Used car warranty: how to check manufacturer and dealer cover and your statutory rights

Key takeaways

A used car can come with three kinds of protection: the seller's legal liability for defects, what is left of the factory warranty and the seller's contractual warranty. You always have statutory rights when buying from a business. For used cars, however, national law may allow the liability period to be shortened by agreement.
The factory warranty is tied to the car and usually continues when the car changes hands. But it doesn't start again, and it ends at whichever limit is reached first: time or kilometres.
Manufacturers give 2–7 years of warranty on new cars. Mercedes-Benz quotes 2 years in Slovenia, Kia 7 years or 150,000 km in the Czech Republic. With a 2–4-year-old used car, any remaining cover therefore depends on the brand and on whether the first owner took out an extension.
Extended programmes require maintenance to the manufacturer's specifications, and some also require servicing within the authorised network. The traction battery often has a separate, longer warranty: Hyundai quotes 8 years or 160,000 km in the Czech Republic.
Carvago provides a free extended warranty with every car.

A used car warranty is one of the main reasons why a young used car is often a better buy than the cheapest new car. A car aged 2–4 years often still has some of its factory warranty left, and its servicing risk is low, though not zero. But the advert usually just says “under warranty”. That may mean cover from the manufacturer, cover from the seller or simply the buyer's statutory rights. Each of them covers something different, lasts for a different length of time and is claimed from someone else. If you know which protection applies and what the car has to meet to keep it, you can buy even an ex-lease or ex-fleet car with peace of mind.

What can a used car warranty mean?

The basic distinction is simple. Statutory rights for faulty goods arise from the purchase itself. A warranty is a voluntary promise from the manufacturer or seller, and it applies under conditions the provider sets itself.

Type of protection	Who provides it	What it covers	What it depends on
Legal liability for defects	The seller you buy the car from	A lack of conformity with the contract that already existed at handover	A consumer buying from a business, the law of the country concerned, any agreement to shorten the period for used cars
Factory warranty	The manufacturer	Defects covered by the original new-car warranty	Warranty start date, time and mileage limits, servicing to the manufacturer's specifications
Manufacturer's extended warranty	The manufacturer or its partner, depending on the programme terms	Cover after the basic warranty has expired	Purchase or activation, age, mileage, servicing (within the authorised network for some programmes)
Traction battery warranty	The manufacturer	Battery faults, or a drop in capacity below a set threshold	Separate terms, age, mileage, how capacity is measured
Seller's warranty	The seller or an insurer named in the contract	Agreed faults or listed parts	List of covered parts, exclusions, claim limits, excess, repair approval procedure

Two offers “with warranty” can therefore differ more in scope than in the number of months. A warranty that covers parts as well as labour and diagnostics is worth more than one that covers a narrowly defined component.

What statutory rights do you have against the seller?

When you buy a used car from a business as a consumer, EU rules on the sale of goods apply (Directive 2019/771). The seller is liable for the car being in conformity with the contract at handover, i.e. with the agreed characteristics and the condition described. This protection applies alongside the factory and extended warranties, and no voluntary warranty replaces it. A statement such as “our warranty doesn't cover this part” therefore says nothing about whether the seller is legally liable for the defect.

With a used car, its age, previous use and normal wear and tear are taken into account. Worn brake pads are not a defect. An undisclosed fault that means the car doesn't match its description is.

The directive allows member states to let the liability period for used goods be shortened by agreement. The length of this period, the deadlines for reporting a defect and the rules on burden of proof therefore vary from country to country. When buying from abroad, it matters who the contracting seller is and which law governs the contract. Anyone buying through Carvago concludes the contract directly with Carvago, not with a foreign car dealer. If you buy from a private seller, consumer rules don't apply.

Does the factory warranty transfer to the new owner?

Yes, the factory warranty is usually tied to the car, so it continues when the car changes hands. But the new owner only takes over the remaining part and must continue to meet its conditions.

The warranty doesn't start on the day the current owner bought the car. The date of first registration is a guide, but the exact start date is set by the warranty documentation. With an ex-demonstrator, part of the warranty may have run out before the car was first sold.

With a warranty limited by both time and kilometres, whichever limit is reached first applies. A hypothetical example: a car with a 7-year or 150,000 km warranty has covered 150,000 km in four years. Its factory warranty has ended, even though by age it would have three more years to run. With ex-fleet and ex-lease cars that do a lot of motorway driving, the mileage limit is therefore often reached before the time limit. How to assess the mileage itself is covered in the article on used car mileage.

Factory warranty on a used car: examples from manufacturers

The examples show different types of warranty; they are not a ranking. Terms vary by market and year of manufacture, and only the car's own warranty documentation applies to the car you are buying.

Manufacturer and market	Warranty according to the manufacturer	What it means for a 2–4-year-old used car
Mercedes-Benz, Slovenia	2 years on a new car	Without an extension, the factory warranty on a three- to four-year-old car has already ended
Škoda, Czech Republic	2 years, up to 5 years with an extended warranty	Any remaining cover depends on whether the first owner bought the extension
Volkswagen, Czech Republic	Extended warranty up to 5 years or 150,000 km	As with Škoda, plus a mileage limit
Lexus, Czech Republic	3 years or 100,000 km	Ends on a three-year-old car; sooner with high mileage
Hyundai, Czech Republic	5 years with unlimited mileage	Even high mileage won't exhaust the limit
Kia, Czech Republic	7 years or 150,000 km	Plenty of time is left; the limiting factor is more likely to be kilometres
MG, Czech Republic	84 months or 150,000 km from first registration (cars registered from 1 January 2021)	Terms vary by registration date
Dacia Zen, Czech Republic	Repeatedly renewed cover up to 7 years of age or 150,000 km	Applies only if the car meets the programme's conditions
Toyota Relax, Germany	Cover up to 15 years from first registration or 250,000 km	The upper limit of the programme; whether cover continues for a given car depends on its terms

Cars of the same brand and age can therefore have completely different protection. One has an extension, another only the original warranty, and a third has already exceeded its mileage limit.

Does a car under warranty have to be serviced at a main dealer?

Not for the factory warranty. EU rules on servicing cars under warranty don't allow manufacturers to make the warranty conditional on routine maintenance being carried out by their authorised network. The condition is maintenance to the manufacturer's specifications: service intervals kept, prescribed work carried out, and fluids and parts of the correct specification used. Warranty repairs paid for by the manufacturer are, however, carried out by an authorised workshop.

In a dispute, what counts is proof. An invoice with the date, mileage, itemised work and oil specification carries more weight than a stamp saying “oil change”. Extended and service-renewed programmes have their own rules. Some of them require servicing within the authorised network, and if the car misses a single service, the cover may end.

Traction battery warranty

In electric cars and hybrids, the traction battery has its own warranty, which is usually longer than for the rest of the car. Hyundai in the Czech Republic quotes 8 years or 160,000 km for high-voltage traction batteries. With a 3–4-year-old used electric car, the battery is therefore usually still under warranty even if the factory warranty on the car itself has ended.

The terms distinguish between two situations:

Battery failure: a fault covered by the warranty terms like any other.
Loss of capacity: gradual ageing of the cells. This is only covered if the terms state a guaranteed capacity and how it is measured. Any loss that leaves the capacity above this threshold is borne by the owner.

So “battery under warranty” doesn't promise the original range. It only says who pays if the battery fails or drops below the guaranteed threshold.

Extended warranty and seller's warranty: what matters in the terms

A manufacturer's extended warranty and a seller's warranty are worth having if they cover expensive parts and you can reasonably claim on them. With a young used car, the servicing risk is low, not zero. A contractual warranty transfers it from the owner to the provider. Carvago provides a free extended warranty with every car.

Condition	Why it matters
List of covered parts	A general “engine and gearbox” may not include related parts and electronics
Limit per repair and total claim limit	Determines how much of a repair the provider pays for
Excess and labour covered	Even an approved repair may cost the owner something
Exclusions for wear and for defects known before the warranty was taken out	Separate a covered failure from normal running costs
Servicing obligations	If they are not met, the right to claim lapses
Repair approval and service network	Determine what to do in the event of a breakdown, including abroad

A shorter warranty with clear cover for important parts is often more useful than a long warranty with low limits.

What to check before buying: a checklist

Date of first registration and warranty start date. They may differ for ex-demonstrators and pre-registered cars.
Mileage against the mileage limit. Time left on the warranty is no use without kilometres left.
Service history. Dates, mileage and work should follow on from each other and match the manufacturer's schedule.
Confirmation of cover by VIN. An authorised workshop can use the VIN to check whether the factory warranty and any extension are valid, and for which market.
Claim conditions. Exclusions, limits, excess and the repair approval procedure.

If you buy from abroad on your own, you have to sort all this out with a foreign seller and workshop, often in a foreign language and with documents from another market.

What to watch out for when buying and if something goes wrong

A warranty that only exists in the advert. Who provides the cover and on what terms belongs in the contract or the warranty certificate.
Length instead of scope. A long warranty with a short list of parts leaves much of the repair cost to the owner.
Gaps in the service history. Assurances that the car “definitely had its services” won't help in a dispute.
The end of the factory warranty doesn't mean the end of protection. Your statutory rights against the seller run separately.
A warranty doesn't mean free motoring. The owner pays for routine maintenance and worn parts.

If a fault occurs, safety and preventing further damage come first. Then note down the symptoms, the date and the odometer reading, and report the fault to the seller or warranty provider before the repair. A repair ordered without their approval may not be reimbursed. Invoices, reports and written communication show what you reported and what the workshop repaired.

Carvago: an inspected car, a warranty and a clear seller

With a used car from abroad, it isn't enough to know how much factory warranty is left. Just as important is who is responsible for the car. Carvago buys the car from the original seller before sale, becomes its owner and takes on its risks. The customer buys directly from Carvago and doesn't have to deal with a contract with a foreign car dealer under foreign law.

Before the customer decides to buy, a technician inspects the car as part of CarAudit™ with up to 270 checkpoints. The inspection covers available information on the car's history and legal status, an inspection of the exterior, interior and technical components, diagnostics and a test drive. The customer knows the result before deciding, and Carvago guarantees the condition stated in the CarAudit™ certificate. If Carvago advises against the car after the inspection, the customer doesn't pay for the CarAudit™ of the next car.

Carvago adds a free extended warranty to every car. The inspection, the guarantee of the described condition and the extended warranty therefore cover the risk both before the contract is signed and after the car is handed over.

FAQ

Does the factory warranty also apply to a car imported from another country?

That depends on the warranty documentation of the individual car. Extended and service-renewed programmes tend to be tied to the market where they were taken out. Toyota Relax, for example, is run by Toyota's national organisations, and the terms in the table are those of Toyota in Germany. Before buying an imported car, it's worth having an authorised workshop confirm by VIN whether the cover also applies in the country where you'll be driving.

Does the same protection apply when a business buys the car?

EU consumer rules on the sale of goods protect consumers. A company or sole trader buying a car for business purposes is subject to general commercial rules, and the seller's liability tends to be narrower. The factory warranty and the seller's contractual warranty apply regardless of who bought the car.

Does the warranty include recovery or a courtesy car?

Usually not. Breakdown recovery and a replacement car are part of assistance services, which the manufacturer provides separately or links to servicing within the authorised network. A repair warranty doesn't entitle you to them.

Does a missing paper service book mean the end of the warranty?

No. Most manufacturers keep service histories electronically, and maintenance can also be proven with invoices and job sheets. What matters is that the maintenance is documented and meets the manufacturer's specifications.
