DS 7 vs. Lexus UX: Complete comparison 2026

The luxury French SUV DS 7, formerly known and commonly available on the used car market under its original name DS 7 Crossback, attracts with its unmistakable avant-garde design and first-class level of driving comfort. Opposing it is the confident Japanese crossover Lexus UX, which instead bets on expressive sharp curves, legendary reliability, and advanced full hybrid or electric powertrains. Let's take a detailed look at how these two unconventional premium segment rivals stand in a direct comparison and which of them could be the best choice for your daily travel.

Looking at the exterior dimensions, it is clear at first glance that although both models target premium-oriented customers, each of them plays in a slightly different league. The French DS 7 (often also known by its former designation DS 7 Crossback) gives a much more robust and massive impression of a full-fledged family car. The Japanese Lexus UX, on the other hand, bets on very compact proportions, which with their low build and dynamic silhouette are closer to traditional hatchbacks with a raised chassis. This difference in approach has a fundamental impact on how the cars behave in the real world and how representatively they appear on the road. Clear advantages and disadvantages for different types of drivers thus result from the different concepts.

In terms of specific numbers, the DS 7 with its base length of 4573 mm is approximately 78 mm longer than the Lexus UX, which measures exactly 4495 mm. Even more striking is the difference in height – the DS 7 is roughly 100 mm taller, which contributes not only to an overall more confident appearance and a higher seating position behind the wheel but also to a better view of traffic. The body width is similar, where the DS 7, with a value exceeding 1895 mm, surpasses its Japanese competitor by a noticeable 55 mm. The longer wheelbase of the French car (2738 mm compared to 2640 mm for the Lexus) primarily benefits rear-seat passengers and overall ride smoothness, while the shorter wheelbase of the Lexus aids greater agility in tight corners.

The choice between these two models from the perspective of exterior dimensions thus depends primarily on the environment in which you will move most often. Lexus UX, thanks to its compact dimensions, narrower body, and shorter wheelbase, is an absolutely ideal companion for crowded city streets, where you can park it much more easily and maneuver skillfully through traffic. In contrast, DS 7 represents a significantly more spacious alternative with a generous footprint. While the larger body might trouble you a bit when maneuvering in narrow underground garages, it fully rewards you with excellent interior comfort and plenty of living space during family trips and long highway journeys.

When it comes to comparing practicality and luggage compartment volume, DS 7 and Lexus UX represent two completely different approaches, which can be a decisive factor for many buyers on the used car market. While the French SUV emphasizes family usability and generous space for long journeys, the Japanese crossover focuses more on urban agility and compact design, to which the trunk size had to be sacrificed. For families or active individuals who often transport sports equipment or simply need plenty of space, this difference is absolutely fundamental.

The French DS 7 model confidently dominates in this regard on the market for roughly four-year-old used cars. In its basic configuration, it offers a generous volume of 555 liters, which is space easily sufficient for weekend shopping and longer family vacations, where you get room for several extra suitcases. Furthermore, after folding the rear seats, the capacity increases to an impressive 1,752 liters. A huge advantage for those interested in electrified models is the fact that the popular E-Tense plug-in hybrid versions, thanks to the clever placement of batteries under the floor, do not lose a single liter of this above-average space and fully match the conventional internal combustion versions.

The Lexus UX, on the other hand, comes up significantly short in the luggage-carrying discipline, as its trunk is similar in volume to smaller hatchbacks. The standard hybrid version with front-wheel drive offers about 320 liters, but the situation is even more compromised for the sought-after all-wheel-drive variants (E-Four). In these, the rear electric motor reduces the capacity to just 283 liters. When the seats are folded, you get a maximum space of 1,231 liters. As a result, while the DS 7 fulfills the role of a full-fledged family car without compromise, the Lexus UX serves more as an exceptionally reliable and stylish car for couples who are fully satisfied with a smaller transport capacity for everyday city life.

Trailer weights, or towing capacity, represent one of the biggest technical differences between these two cars and play a key role for buyers with an active lifestyle. While the DS 7 as a classic luxury SUV bets on a more robust construction and powerful internal combustion and hybrid powertrains, the Lexus UX pays the price for its compact body and platform focused primarily on efficient urban operation. Although precise records for comparison are missing in the official tabular database for these specific models, completely different parameters follow from the manufacturers' technical specifications.

The French representative, the DS 7, standardly allows towing a braked trailer weighing between 1290 and 1850 kg, depending on the chosen engine. The great news is that even the popular E-Tense plug-in hybrid versions maintain a decent capacity and can handle a solid 1200 to 1550 kg. For an unbraked trailer, the DS 7 most often reaches the legislative maximum of 750 kg. Conversely, the Lexus UX, including the most widespread hybrid variants UX 250h or the newer 300h, is strictly limited to a maximum weight of 750 kg for both braked and unbraked trailers. The fully electric UX 300e version does not allow trailer towing at all.

In practice, these differences mean completely different use cases. The DS 7 can easily handle transporting a heavy caravan or boat, offers generous space for a few extra suitcases in a larger cargo trailer, and its total towing power is more than sufficient for weekend shopping or longer holidays with the whole family. The Lexus UX, on the other hand, will satisfy more basic utility needs – it will serve at most for hauling garden waste in a light trailer or for installing a bike rack on the tow bar.

Therefore, if you are choosing a used car around four years old and anticipate frequent towing of heavier loads, the DS 7 is clearly the more logical and practical choice of the two. The Lexus UX, by contrast, remains an excellent companion for stylish and economical daily commuting, but with very limited towing capabilities.

When comparing the powertrains of roughly four-year-old used cars (around the 2022 model year), a fundamental difference in the philosophy of both manufacturers emerges. The DS 7 (formerly known as the DS 7 Crossback) bets on a traditional European approach, combining turbocharged petrol and diesel engines with powerful plug-in hybrids (PHEV). These plug-in hybrids represent the absolute top of the range, delivering up to 300 hp and being the only ones to provide all-wheel drive. In contrast, the Lexus UX prioritizes maximum efficiency in suburban traffic and overall mechanical reliability, which is why it completely omits diesel engines. Its main weapon is a highly efficient full-hybrid system, which, unlike the DS 7, does not require charging from the grid. The range is then complemented by a purely electric version. If you are a driver who spends a lot of time on motorways or requires high performance and dynamics, the DS 7 with E-Tense engines or an economical diesel will be the better choice. The Lexus UX, on the other hand, will appeal to calmer drivers and those looking for an agile car for the city, where full-hybrid technology guarantees unrivaled fuel consumption and legendary maintenance-free operation.

DS 7 Engines

The basis of the range for the DS 7 from the 2021–2022 period is the economical 1.5 BlueHDi four-cylinder diesel with 96 kW (130 hp), which is an ideal choice for drivers with high motorway mileage. The petrol alternative consisted of 1.6 PureTech turbocharged four-cylinders in versions with 132 kW (180 hp) and 165 kW (225 hp). However, it is important to note that purely petrol engines gradually disappeared from the European range with the arrival of newer model years and modernization, being replaced by electrified variants. All mentioned internal combustion engines are standardly paired with an exceptionally smooth-shifting 8-speed automatic transmission and drive the front wheels exclusively. The pinnacle of the brand's innovation is the E-Tense plug-in hybrid versions. The basic E-Tense 225 offers a combined output of 165 kW (225 hp) with front-wheel drive, while the top-of-the-line E-Tense 4x4 300 adds a second electric motor to the rear axle. This not only increases the total system output to an impressive 221 kW (300 hp) and torque to 520 Nm but also, as the only version, ensures confident traction thanks to all-wheel drive.

Lexus UX Engines

The Lexus UX is primarily built on electrification and driving smoothness. Although a purely naturally aspirated 2.0-liter petrol UX 200 with 126 kW (171 hp) was available in the early stages of production, this engine was removed from European price lists relatively early. The vast majority of used cars on the current market are thus equipped with the sophisticated UX 250h full-hybrid powertrain. This system combines a reliable naturally aspirated 2.0-liter four-cylinder with an electric motor and achieves a very decent combined output of 135 kW (184 hp). It is exceptionally efficient and, unlike the DS 7, you can purchase it either with front-wheel drive or as an AWD (using the E-Four system with a small independent electric motor at the rear). In the hybrid, power is transmitted via an electronically controlled planetary e-CVT gearbox, which ensures completely smooth acceleration. For those interested in locally emission-free driving, Lexus also prepared the fully electric UX 300e model with 150 kW (204 hp) and 300 Nm of torque. Models in the generation around 2021 (before the deployment of a significantly larger battery in 2023) offered a 54kWh battery, making this electric car primarily a great comfortable vehicle for daily commuting to work.

While the DS 7 relies on French elegance supported by a wide range of plug-in hybrids and diesel engines, the Lexus UX paves the way for Japanese precision with an almost exclusive focus on exceptionally reliable self-charging hybrids. Choosing the right power unit is key to long-term satisfaction, as both manufacturers take very different approaches to electrification. The recommendations below reflect real-world market experience with roughly four-year-old used cars, where the ratio of real-world performance, fuel consumption, and mechanical durability plays a major role.

For the DS 7, we recommend: Plug-in hybrid E-Tense 225 (165 kW)

The E-Tense 225 plug-in hybrid version with front-wheel drive represents the most rational choice for a roughly four-year-old DS 7 (around the 2022 model year). The legendary and bulletproof 2.0 BlueHDi diesel disappeared from the range at the end of 2020, and the smaller 1.5 BlueHDi engine in models before 2023 can suffer from an undersized 8mm camshaft chain. Therefore, the E-Tense 225 version makes the most sense on the used car market – it combines a 1.6 PureTech petrol four-cylinder with an electric motor, giving the car a very solid 165 kW (225 hp).

• Technical advantages: A battery with a usable capacity of 13.2 kWh allows for a real-world pure electric range of around 40 km, which is ideal for daily city commuting without local emissions. Furthermore, the smooth-shifting eight-speed e-EAT8 automatic perfectly complements the overall soothing suspension tuning.
• Risks and how to prevent them: To make this powertrain sensible and avoid damage, you must charge the vehicle regularly. When driving with a long-term discharged battery, the heavier SUV is powered only by the petrol engine, fuel consumption rises to 8 liters per 100 km, and the engine is under more strain. For a used car, have the battery degradation (SOH – State of Health) checked at a service center. Also, ensure the oil change interval is shortened to a maximum of 15,000 km or 1 year – in plug-in hybrids, oil is often diluted with petrol due to frequent cold starts of the internal combustion engine, which degrades its lubricating properties.
• Who it's for: Ideal for suburban drivers with home or office charging options who appreciate absolute silence on board during their daily commute but need a full range for longer trips on weekends.

For the Lexus UX, we recommend: 250h (135 kW / 184 hp)

For the Lexus UX, the choice on the used car market is absolutely clear – the UX 250h self-charging hybrid. The fourth generation of the hybrid system from Toyota and Lexus represents the absolute pinnacle of reliability and perfectly matches the character of this premium city crossover.

• Technical advantages: The naturally aspirated two-liter four-cylinder engine operating in the efficient Atkinson cycle is connected to an electric motor via a sophisticated e-CVT planetary gearbox. The system lacks a conventional starter, alternator, turbocharger, dual-clutch transmission, or a sensitive dual-mass flywheel – components that most often fail in common used cars are simply absent here. Real-world fuel consumption easily stays between 5 and 5.5 l/100 km, even in heavy city traffic.
• Risks and how to prevent them: Mechanically, this powertrain is almost indestructible and easily handles mileages in the hundreds of thousands. The only critical maintenance that many owners neglect is cleaning the hybrid battery cooling filter (the intake grille is located near the rear seats). If the filter becomes clogged with dust and pet hair, the battery will start to overheat, which can lead to premature failure. Ensure the filter has been regularly cleaned or replaced. In cars that are driven infrequently, a discharged standard 12V battery can also occasionally cause trouble.
• Who it's for: For any city and suburban driver who wants a luxuriously crafted car with minimal operating costs, bulletproof reliability, and refuses to be limited by searching for charging cables or stations.

Real-world fuel consumption: Paper withstands everything, reality differs

When choosing a used premium car around four years old, such as the DS 7 and Lexus UX, it is crucial not to rely solely on official laboratory data from manufacturers. Values measured according to the earlier NEDC or newer WLTP methodology are often more optimistic than daily reality. To get an accurate picture of actual operating costs, it is best to look at databases created by drivers themselves. By far the most faithful representation of the real fuel consumption of these cars is provided by user data from the Spritmonitor.de server, which forms the basis of our comparison of engines relevant to the used car market.

Looking at the real-world data, it is clear that both manufacturers approach the issue of efficiency differently. The French DS 7 offers a classic and very wide range of fuels. The paper king is the E-Tense plug-in hybrid version, which in the real world achieves an average of around 4.5 l/100 km. However, one essential rule must be added here – this value is directly proportional to the frequency of charging. If you do not regularly recharge the heavy SUV from the grid, consumption skyrockets. In contrast, the traditional diesel engine in the DS 7 confirms its reputation as an economical workhorse and, with an average of 5.7 l/100 km, represents the most stable choice regardless of the route profile. Conversely, with the powerful petrol engine in the DS 7, performance takes its toll, and an average consumption approaching the eight-liter mark shows that downsizing in larger SUVs does not always bring miraculous savings.

The Japanese Lexus UX, on the other hand, bets almost exclusively on proven hybrid technology. The UX 250h variant is a masterpiece of efficiency. A long-term average of 5.6 l/100 km in practice means that the petrol "full-hybrid" can outperform even the diesel engine in the DS 7 in real-world traffic, without any need to plug the car in. The classic purely petrol UX 200 version (less represented on the used car market) is naturally thirstier with an average of 7.0 l/100 km, yet it performs significantly better compared to the conventional petrol engine in the DS 7.

For the average user, clear recommendations follow from these trends. If you spend most of your time in the city, in traffic jams, and on suburban roads, the Lexus UX 250h will be an unrivaled choice for you in terms of consumption and user comfort. It offers diesel-like fuel consumption but with the quietness and smoothness of petrol. If you swallow thousands of highway kilometers a month across the country, it still makes the most economic sense to go for the diesel DS 7 1.5 BlueHDi. The plug-in hybrid DS 7 E-Tense is then ideal for disciplined drivers who have the possibility of daily home or company charging and want to combine locally emission-free commuting with longer weekend trips.

Overall, operating costs associated with fuel consumption should be one of the decisive factors when choosing between these two cars. While the DS 7 scores with versatility and offers a specific type of drive for every driver (diesel, petrol, PHEV), the Lexus UX clearly proves that a precisely tuned self-charging hybrid represents one of the most versatile and least demanding solutions for efficient daily mobility today.

Used Car Market Situation and Price Range

When choosing an approximately four-year-old premium car (model year 2021–2022), an interesting difference in the approach to the residual value of both models emerges. While the French DS 7 Crossback initially undergoes a slightly steeper price drop, which significantly favors used car buyers, the Japanese Lexus UX holds its value very firmly thanks to its reputation for bulletproof reliability.

DS 7 Crossback (2020–2022)

• Base engines: Diesel BlueHDi variants and proven PureTech petrol engines with a mileage of around 100,000 km can be purchased very advantageously on the used car market, usually in the range of €16,000 to €22,000.
• Plug-in hybrids (E-Tense): Technologically more advanced and powerful versions with the possibility of external charging (often supplied in top Rivoli or Opera trims) most often range between €26,000 and €33,000.
• Buyer's advantage: A used DS 7 model offers an extraordinary price-to-value ratio. The most dramatic part of the depreciation has already been paid by the first owner, so for the price of a common new lower-middle-class car, you get a uniquely designed and exceptionally spacious SUV with opulent equipment.

Lexus UX (2020–2022)

• Dominance of hybrids: The proven UX 250h hybrid engine overwhelmingly prevails on the secondary market. Base versions with higher highway mileage start roughly above the €20,000 mark.
• Higher trims: Popular and more aggressively designed F Sport versions, or models with all-wheel drive (E-Four) and a clear service history, sell in good condition for amounts between €26,000 and €35,000.
• Buyer's advantage: Although you will need a slightly higher budget to purchase a used Lexus, the car will hold its residual value more reliably even when you eventually resell it. Another advantage is the minimal risk of expensive service interventions.

Indicative Price Comparison (cars approx. 4 years old)

Price Verdict
If you are looking for ostentatious luxury equipment, sophisticated interior details, and generous space at the most advantageous purchase price, the DS 7 Crossback is a great choice that cleverly benefits from the depreciation of French luxury cars. If, on the other hand, you care about future value retention and low fuel consumption in city traffic, the Lexus UX will easily justify its higher purchase price at a used car dealership and reward you with above-average reliability.

Safety and Euro NCAP Results

Both compared cars, the DS 7 and Lexus UX, achieved the maximum five-star rating in independent Euro NCAP safety tests. However, when evaluating safety on the used car market, it is crucial to put these results into the correct context and take into account primarily the year the tests were conducted.

Euro NCAP testing protocols are constantly evolving and becoming stricter over the years. Percentage results from different years cannot be directly compared, as the requirements for obtaining the same number of points, especially in the areas of active safety and protection of vulnerable road users, are constantly increasing.

DS 7: Stable Foundation from 2017

The DS 7 model (initially sold as the DS 7 Crossback) underwent crash tests in 2017. It showed very solid structural protection of the cabin with an excellent rating of 91% for adults and 87% for children. The car was already equipped with an automatic emergency braking (AEB) system as standard, which helped it achieve 76% for safety assistants at the time. However, it is necessary to mention that due to the gradual aging of standards, the validity of this Euro NCAP certification expired in January 2024. Although it is a very safe family SUV from a structural point of view, from today's perspective, the range of its assistance systems no longer fully corresponds to the strictest current standards, and the older architecture of the DS 7 thus lags slightly behind the most modern cars.

Lexus UX: Stricter Tests and Advanced Assistance from 2019

The Lexus UX underwent testing two years later, in 2019, when significantly stricter Euro NCAP evaluation rules were already in place. In adult protection, the car excelled with a score of 96%, and child protection reached a very good 85%. Mainly thanks to the implementation of the modern second-generation Lexus Safety System+ package, the car performed much better in protecting vulnerable road users (82%). This system already handled more advanced cyclist detection scenarios during the day and automatic pedestrian recognition even in poor lighting conditions at night.

Final Summary
Although both cars offer a high standard of passive safety and a full five-star rating from the time of their market launch, the Lexus UX represents a more modern and comprehensive choice. Because it underwent testing in 2019 according to more demanding criteria and features a more advanced generation of active assistants focused even on complex urban scenarios (e.g., night-time pedestrian detection), its safety equipment corresponds slightly better to the latest safety standards than the older architecture of the DS 7.

In addition to standard equipment, each model offers several unique features that may be decisive for the customer. Both vehicles bring much more than just basic equipment, with each choosing a completely different approach to offering the driver maximum luxury, comfort, and added value.

DS 7: Parisian Luxury and Avant-Garde Technology

The French SUV focuses on a unique design experience and technology inspired by higher classes. The DS 7 (formerly sold with the Crossback suffix) is a showcase of French "haute couture" in the automotive world.

• Chassis and Comfort: The DS Active Scan Suspension system uses a camera located behind the windshield that scans the road surface ahead of the car in real-time. The electronics then instantly adjust the damping stiffness for each wheel individually, creating the effect of the legendary "flying carpet."
• Design and Materials: The interior is full of unique elements. It is dominated by luxury materials such as Nappa leather with a watchstrap pattern, crystalline controls with Clous de Paris guilloché, and pearl stitching. After starting, an analog B.R.M R180 clock elegantly flips out from the dashboard.
• Lighting and Safety: A prominent feature is the DS Active LED Vision headlights. When the car is unlocked, they not only light up in purple, but their individual modules also rotate 180 degrees in a striking display. For safer night driving, the car is equipped with the DS Night Vision system – an infrared camera that highlights pedestrians and animals in the dark on the digital instrument cluster.
• Powertrains: In higher trim levels, the backbone of the range consists of E-Tense plug-in hybrid systems. In roughly four-year-old used cars, you will often encounter the top-of-the-line 300 hp (or even 360 hp) engine, which, thanks to two electric motors, offers all-wheel drive and very dynamic driving with the possibility of driving purely on electricity.

Lexus UX: Japanese Craftsmanship and Hybrid Efficiency

The compact crossover from Lexus, on the other hand, bets on technological reliability, quiet operation, and details inspired by traditional Japanese craftsmanship. It will particularly appeal to drivers looking for peace and perfect ergonomics without the need for plug-in charging.

• Powertrain and Efficiency: The fourth generation of the Lexus Self-Charging Hybrid system excels in immense reliability and extremely low fuel consumption in city traffic. The system seamlessly alternates between gasoline and electric power without any driver intervention.
• Aerodynamics and Functional Design: The rear combination lights with integrated Aero Stabilizing Blade Lights are not just a design whim; they effectively direct airflow around the rear of the car for better stability. This clever engineering approach is also reflected in the specially shaped wheels that cool the brakes while driving.
• Interior and Traditional Crafts: Lexus brought materials inspired by Japanese culture to the UX model. The dashboard surface can have a Washi texture (traditional Japanese paper used in interior sliding doors). In some trims, the leather seats use the Sashiko stitching technique, which is known for its strength and is used in the production of martial arts uniforms.
• Climate Comfort and Audio: The Lexus Climate Concierge function is one of the smartest climate control systems on the market. It automatically links interior heating or cooling with seat heating and ventilation, as well as steering wheel heating, so that the driver and passengers reach the ideal temperature as quickly as possible. A traditional trump card of higher trims is the top-tier Mark Levinson audio system.
• Controls and Infotainment: In models from 2019–2022, a specific Remote Touchpad is often found on the center console, which functions similarly to a laptop mouse. Although it takes some getting used to, combined with physical audio buttons cleverly hidden in the armrest, it shows Lexus's different approach to ergonomics.

DS 7

Advantages:

• Avant-garde and premium interior design using luxury materials (top-tier leather, Alcantara, and details inspired by Parisian jewelers).
• Highly comfortable chassis with DS Active Scan Suspension technology, which uses a camera to read the road ahead and actively adjusts damper stiffness.
• Generous interior space and a practical, easily accessible trunk with a very respectable capacity of 555 liters.
• Excellent cabin soundproofing ensuring a quiet and peaceful ride even at higher highway speeds.
• A wide range of advanced plug-in hybrid powertrains (E-Tense) with the option of powerful all-wheel drive.

Disadvantages:

• More complex controls and slower response of the older generation infotainment (a system from before the major Stellantis software update).
• Specific ergonomics – for example, the placement of window controls on the center console requires a longer adjustment period.
• More detached steering and an overall less engaging driving experience, which won't thrill drivers looking for sportier behavior.
• Faster depreciation on the used car market compared to traditional German or Japanese premium competitors.

Lexus UX

Pros:

• Unrivaled reliability and legendary build quality, ensuring trouble-free long-term ownership.
• Highly efficient and economical full hybrid system (UX 250h) with minimal maintenance requirements and exceptionally low fuel consumption in city traffic.
• Rich standard equipment across all trim levels, including the comprehensive Lexus Safety System+ package.
• Low center of gravity and an excellently tuned chassis, thanks to which the car offers surprising agility and driving dynamics in corners.
• Very comfortable and ergonomically well-designed front seats suitable even for long journeys.

Cons:

• Extremely small and shallow luggage compartment (around 320 liters for the front-wheel-drive version; the E-Four all-wheel-drive version has even less volume).
• Cramped space for adult passengers in the rear seats, especially in the knee area and entry space.
• Outdated and frustrating-to-use multimedia system control via a touchpad in cars manufactured before the facelift (until 2022).
• Noisier engine performance and the characteristic "vacuum cleaner" effect of the e-CVT planetary gearbox when maximum acceleration or overtaking is needed.

Based on long-term user experience, breakdown statistics, service reports, and data regularly provided by our detailed comprehensive car audit, we have compiled an overview of the most common problems for both compared models. This information will help you focus on the weak points that buyers of roughly four-year-old used cars should pay the most attention to.

DS 7 (2018–present generation)

The French premium SUV attracts with its avant-garde design and top-tier comfort, but technically it requires a more careful approach and strict adherence to service intervals.

Engines and Powertrain

• 1.5 BlueHDi: In the popular diesel engine from the first years of production (roughly until 2022), one of the best-known problems is the weaker 7mm chain connecting the camshafts. If maintenance is neglected, it can break and cause fatal engine damage. Pay special attention to rattling sounds during a cold start. Later versions received a reinforced 8mm chain.
• 1.6 PureTech: Turbocharged direct-injection gasoline engines tend to form carbon deposits on the intake valves during frequent city driving. This manifests as power fluctuations and rougher operation. It is recommended to use fuel with additives and regularly take the car on longer trips.
• Plug-in hybrids (E-Tense): Software glitches occasionally occur in these versions, manifesting as confused switching between electric and combustion modes. Less frequently, owners report faults with the onboard charger, which can suddenly stop communicating with public charging stations.

Chassis and Suspension

Models equipped with the DS Active Scan Suspension adaptive chassis provide excellent comfort, but the system depends on a camera located behind the windshield. If the glass in the camera area is dirty or a sensor fails (often after an unprofessional windshield replacement), the suspension goes into a backup – noticeably stiffer – mode.

Infotainment and Electronics

Most complaints are directed at the central multimedia system. Especially with older software versions, slow responses, freezing during navigation rendering, or random screen restarts occur. The solution is usually a software update to the latest version at an authorized service center.

Summary for the DS 7:
The car offers exceptional style but hides some technical risks, especially with specific engines. The basis for trouble-free operation is verifiable and shortened service care. Before buying this model, an independent technical inspection focusing on the timing chain, hybrid system diagnostics, and checking for play in the adaptive chassis should be an absolute necessity.

Lexus UX (2019–present generation)

The Japanese crossover is considered a benchmark for reliability. According to most consumer rankings and our own inspections, it is among the least problematic cars in its class. Problems are limited more to user details than mechanical failure.

Powertrain and Battery

• Hybrid system (UX 250h): The combination of a two-liter naturally aspirated gasoline engine and an electric motor with an e-CVT planetary gearbox is extremely durable. The system has no traditional clutch or starter, which eliminates many potential faults.
• 12V battery: Perhaps the most common "real" problem is the small 12V onboard battery. If you use the vehicle only for very short trips or leave it sitting for several weeks without movement, the battery can easily discharge, and the car cannot be started (or rather, the hybrid system cannot be "woken up").

Infotainment and Interior

• Infotainment control: Until the update (late 2022), Lexus stubbornly used the so-called Remote Touchpad to control the multimedia system. In terms of functionality, it is not a fault, but for many users, it is an ergonomic problem. The system is slow, graphically outdated, and operating it while driving is distracting. Very occasionally, there were complaints about connection drops via Apple CarPlay or Android Auto.
• Interior rattling: Although build quality is generally top-notch, some owners of four-year-old or older units report occasional rattling of harder plastics in the luggage area or trunk cover when driving on very poor surfaces.

Body and other systems

Early models from 2019 and 2020 may experience issues with moisture condensation inside the rear connected LED light bar. Most of these defects were resolved under warranty by replacing the seals; however, for used cars, we recommend checking if water is leaking into the light.

Lexus UX Summary:
The Lexus UX represents a purchase with minimal risk. The drivetrain is "bulletproof," and problems are usually just minor user inconveniences. The only compromises are an outdated infotainment system and a smaller luggage compartment, but in terms of long-term reliability, Japanese engineering wins by a wide margin in this comparison.

When buying a used car, a thorough inspection is key. Here are some specific points to focus on for these two models. For maximum peace of mind before signing the purchase agreement, a detailed physical inspection of the used car by an experienced mechanic is always worth it.

When choosing a DS 7:

• Infotainment responsiveness and software version: The central touchscreen can occasionally suffer from freezing or slow responses. During the test drive, test the map redraw speed and menu switching. Faster reactions often indicate that the car has updated software, which will save you a trip to the service center.
• Adaptive suspension behavior (Active Scan Suspension): If the car is equipped with a system that uses a camera to read the road and adjust damper stiffness, focus on its performance on cobblestones or potholes. There should be no dull thuds or knocking sounds from below. A malfunctioning or poorly calibrated system significantly reduces ride comfort.
• Battery health in plug-in hybrids (E-Tense): For the plug-in version, check the estimated electric range at full charge in the trip computer. A significant drop compared to factory values indicates degradation of the traction battery, which is a real risk for used cars four or more years old.
• AdBlue system in BlueHDi engines: Diesel units from the Stellantis group can have issues with urea crystallization, which occasionally damages the pump in the tank. During a cold start, watch the dashboard closely for any flickering engine lights or emission system warnings.
• Smoothness of PureTech engines when cold: For gasoline variants (especially more powerful ones), listen to the engine sound immediately after starting. Any rattling, fluctuating RPMs, or hesitation during the first acceleration can indicate engine carbon buildup or approaching timing mechanism issues.

When choosing a Lexus UX:

• Hybrid battery cooling filter: Under the rear seats of the 250h version, there is a cooling vent for the traction battery. Check if the grille and filter are clogged with dust or pet hair. A neglected filter leads to battery overheating and thus a rapid reduction in its lifespan.
• e-CVT transmission smoothness: Lexus's hybrid system is legendary for its smoothness. Any jerking, twitching, or unexpected hesitation when starting or driving at low speeds is completely non-standard for this model and requires in-depth diagnostics.
• Seat bolster wear: Especially in F Sport trim levels, which have seats with very pronounced side bolsters, check the condition of the upholstery on the driver's side near the door.

• Infotainment control functionality (Remote Touchpad): The user interface of older UX models is controlled by a touchpad on the center console. Test moving the cursor to all corners of the screen and check if the touchpad has any "dead spots" or delayed responses.
• Tire condition and type (Run-flat): The Lexus UX was often factory-fitted with run-flat tires with stiffer sidewalls. During the drive, listen for excessive rolling noise or vibrations from the chassis. If the previous owner installed cheap replacements or if the tires are unevenly worn, the comfortable cabin silence will disappear very quickly.
