Car dealer concealed a defect in Germany? What must be disclosed and when you can avoid the purchase

What did the Higher Regional Court of Munich decide?

The Higher Regional Court of Munich (Oberlandesgericht München) dismissed the appeal of a buyer who had avoided her used car purchase for fraud, in German arglistige Täuschung (final judgment of 1 July 2026, 7 U 2446/24). The court refused leave to appeal on points of law, and the judgment is final. The dismissal of her claim by the Regional Court of Munich II of 20 June 2024 therefore stands.

On 26 October 2018 the buyer had bought a Renault estate with 23,761 km on the clock from a car dealership for €23,590. On 6 November 2018 the dealer had repairs carried out on the car, and on 15 November 2018 it handed the car over. About two years later, by a lawyer’s letter that reached the dealer on 14 November 2020, the buyer avoided the contract. She relied on two allegations. First, the dealer had concealed that the car had previously been used as a rental car. Second, it had kept quiet about the work done between signing and handover. According to the buyer, that work concerned the cylinder head, the head gasket, the camshaft, the front and rear axles and the gearbox, among other things. The dealer said it had merely replaced a leaking gasket on the timing cover housing.

Neither allegation succeeded. The rental history was stated in the contract and, according to the salesman’s testimony, had also been mentioned orally. And in the court’s view the dealer did not have to disclose repairs after which the car was free of defects on handover, even if the work was as extensive as the buyer claimed.

Avoidance for fraud or rescission for defects: which way out of a car purchase?

Anyone who wants to give back a used car bought in Germany has two legally distinct tools. Rescission (Rücktritt) is based on a defect, meaning the condition of the car when the risk passes to the buyer (sections 434, 437 no. 2 and 323 of the German Civil Code, BGB). Avoidance for fraud (Anfechtung wegen arglistiger Täuschung) looks at a different moment, the conclusion of the contract: the buyer avoids his or her own declaration to buy, because the seller induced it by deceit (section 123 (1) BGB). Once avoided, the contract is treated as void from the outset (section 142 (1) BGB).

If the seller acted fraudulently, warranty claims fall under the regular limitation period (s. 438 (3) BGB)

The differences matter in practice. Rescission normally requires an unsuccessful deadline for the seller to remedy the defect (section 323 (1) BGB), and warranty claims for a car generally become time-barred two years after delivery (section 438 (1) no. 3 and (2) BGB). For used vehicles sold to consumers the dealer may even shorten this period to one year, but under current law only if it informs the buyer of this specifically beforehand and the shortening is agreed expressly and separately (section 476 (2) BGB). Avoidance needs no deadline for repair. It must be declared within one year of discovering the deceit and is excluded ten years after the contract was made (section 124 (1) to (3) BGB).

Then there is the exclusion of liability. Clauses such as “gekauft wie gesehen” (bought as seen) or a warranty exclusion when buying for a business concern warranty rights, they do not touch avoidance under section 123 BGB. Even a clause excluding avoidance in the event of the seller’s own fraud would be invalid, because according to the Federal Court of Justice a party who deceives deserves no protection (BGH, judgment of 17 January 2007, VIII ZR 37/06, NJW 2007, 1058, para. 18). Where the seller fraudulently concealed a defect, it cannot rely on such an exclusion anyway (section 444 BGB), and warranty claims are then subject only to the regular three-year limitation period, counted from the end of the year in which the buyer learns of the defect and the deceit (section 438 (3), sections 195 and 199 (1) BGB). That is why avoidance is typically the remedy of choice once the warranty has expired or was excluded. In the Munich case almost exactly two years passed between handover and receipt of the avoidance letter.

The price for these advantages is the burden of proof. The buyer must plead and prove the deceit, the resulting mistake, its influence on the decision to buy and the seller’s intent. Most avoidance claims fail at this hurdle in practice, and so did the buyer in Munich.

When does a concealed defect amount to fraud by the dealer?

Deceit can be committed actively or by silence. A seller deceives actively by making false statements, for example by writing “unfallfrei” (accident-free) in the advert while knowing of accident damage, or by giving an untrue answer to a specific question. Silence amounts to deceit only where the seller had a duty to disclose. The seller acts fraudulently if it knows that the information is wrong, or at least considers this possible and accepts that the buyer would not have bought, or not on these terms, without the mistake. Negligence is not enough.

„Nach der ständigen Rechtsprechung des Senats handelt ein Verkäufer bereits dann arglistig, wenn er zu Fragen, deren Beantwortung erkennbar maßgebliche Bedeutung für den Kaufentschluss seines Kontrahenten hat, ohne tatsächliche Grundlagen ins Blaue hinein unrichtige Angaben macht“

“According to the settled case law of the Senate, a seller already acts fraudulently if, in response to questions whose answers are recognisably of decisive importance for the other party’s decision to buy, it makes incorrect statements off the cuff without any factual basis”

BGH, judgment of 7 June 2006, VIII ZR 209/05, BGHZ 168, 64, para. 13 — our translation

A dealer who promises “accident-free” without having inspected the car must therefore make clear that it does not know for certain. Absent specific indications, it is not obliged to inspect the car for accident damage, but a promise that sounds like reliable knowledge makes it liable (BGH, VIII ZR 209/05, para. 15). Conditional intent is sufficient.

Finally, the deceit must have influenced the decision to buy. It need not be the only reason, it is enough that it was one of several causes (BGH, judgment of 22 February 2005, X ZR 123/03, NJW-RR 2005, 1082). This creates a time limit that mattered in Munich: what happens only after the signature cannot have caused the signature. The court expressly left open whether work carried out after the contract was made can ever justify avoiding that contract, because there was no duty to disclose in the first place.

What must a car dealer in Germany disclose without being asked?

Not everything the buyer might be interested in. The Munich court summed up the starting point of the Federal Court of Justice’s case law as follows:

„Insoweit ist beachtlich, dass den Verkäufer keine generelle Verpflichtung trifft, den Käufer von sich aus über alle Umstände aufzuklären, die für den Vertragsentschluss des Käufers von Bedeutung sein könnten“

“In this respect it must be borne in mind that the seller is under no general obligation to inform the buyer, of its own motion, of all circumstances that could be relevant to the buyer’s decision to enter into the contract”

OLG München, final judgment of 1 July 2026, 7 U 2446/24, para. 28, citing BGH, judgment of 13 July 1983, VIII ZR 142/82 — our translation

A duty to disclose exists only where the buyer can expect the information in good faith (Treu und Glauben). For used cars, settled case law applies this above all to accident damage. The reason is economic: accident damage that is more than trivial reduces the market value of the car even after a professional repair, because buyers pay less for a car that has had an accident (merkantiler Minderwert, loss of market value).

„Danach muss der Verkäufer eines Gebrauchtwagens einen Schaden oder Unfall, der ihm bekannt ist oder mit dessen Vorhandensein er rechnet, grundsätzlich auch ungefragt dem Käufer mitteilen, wenn er sich nicht dem Vorwurf arglistigen Verschweigens aussetzen will, es sei denn, der Schaden oder Unfall war so geringfügig, dass er bei vernünftiger Betrachtungsweise den Kaufentschluss nicht beeinflussen kann.“

“Accordingly, the seller of a used car must, as a rule, inform the buyer even without being asked of any damage or accident of which it is aware or whose existence it suspects, if it does not wish to be accused of fraudulent concealment, unless the damage or accident was so minor that, on a reasonable view, it cannot influence the decision to buy.”

BGH, default judgment of 10 October 2007, VIII ZR 330/06, NJW 2008, 53, para. 20 — our translation

A mere trifle need not be disclosed. The Federal Court of Justice draws this line narrowly, though: for passenger cars only very minor external paint damage counts as trivial, not sheet-metal damage, even if it had no further consequences and was cheap to repair (BGH, VIII ZR 330/06, para. 20). A second rule applies regardless of any duty to disclose: if the buyer asks a specific question, the answer must be true. A seller who answers a question about accidents, previous owners or prior use falsely or misleadingly deceives actively.

Former rental car: is a note in the contract enough?

In the Munich case it was. One of ten text fields with the vehicle data on the contract form stated in typescript that, according to the previous owner, the car had been used as a “Taxi- /Miet/Fahrschulwagen”, meaning taxi, rental car or driving school car. The buyer argued that this combined entry did not show that the car had actually been a rental car. Neither the Regional Court nor the Higher Regional Court accepted this: the prior use was expressly named, and the form did not provide for ticking one of the three options at all. In addition, the salesman testified that he had mentioned the rental history orally. The Regional Court found him credible, and the Higher Regional Court saw no reason to doubt that assessment. The vehicle documents also listed a car rental company as the first registered keeper.

Whether a dealer must disclose prior use as a rental car without being asked at all has not, as far as can be seen, been decided by the Federal Court of Justice, and the lower courts are divided. The Higher Regional Court of Stuttgart found a duty to disclose where a young car (first registered in 2006) was sold first-hand after being used exclusively as a rental car by its first owner: for an average private customer such prior use is atypical and usually causes a loss of market value. An incomprehensible note on the order form was not sufficient disclosure (judgment of 31 July 2008, 19 U 54/08). The Higher Regional Court of Cologne requires disclosure at least where a car was used for many years as a taxi, driving school car or rental car, but denied a duty where the rental period lasted only about six months shortly after first registration (judgment of 29 May 1996, 13 U 161/95). The Regional Court of Kaiserslautern rejected any duty to disclose for a former rental car sold as a one-year-old car (order of 25 March 2009, 2 O 498/08). The Munich court did not have to decide the question, because the prior use had been disclosed.

For buyers this means that a clear entry in the contract counts as disclosed, even if it sits inconspicuously between the date of first registration and the mileage. An incomprehensible abbreviation, however, is not enough. Read the contract field by field before you sign, and where an entry lumps together “taxi/rental/driving school”, ask which of these applies. Ideally get the answer in writing.

This should not be confused with consumer warranty law, which has been considerably stricter for dealers since 2022. If a dealer wants to agree that a car deviates from the usual requirements in a particular feature, it must inform the consumer of this specifically before the contract is made, and the deviation must be agreed expressly and separately (section 476 (1) second sentence BGB). Pre-printed tick boxes do not meet this standard, as the Higher Regional Court of Cologne has held. More on this in our article on dealer tick-box disclaimers. That rule did not yet apply to the Munich contract of 2018, and for avoidance the only question is whether the buyer was deceived.

Must the dealer disclose repairs between the contract and handover?

No, at least not where the car is free of defects on handover and the repair does not concern a circumstance that would have to be disclosed anyway. That is the core of the judgment. The court focused on the passing of risk: risk passes to the buyer on handover (section 446 first sentence BGB), and at that point the car must be free of defects. The 2018 contract was governed by section 434 BGB in the version in force until 31 December 2021 (Article 229 section 58 of the Introductory Act to the Civil Code, EGBGB), but in the court’s view nothing has changed as to the decisive point in time.

On handover the car was free of defects. The dealer did not have to disclose the earlier repair.

„Die Beklagte hat ihre Vertragspflichten damit objektiv und subjektiv erfüllt. Ob und welche Instandsetzungsarbeiten zur Erfüllung dieser Vertragspflichten zuvor erforderlich waren, musste die Beklagte der Klägerin nicht mitteilen.“

“The defendant thus fulfilled its contractual obligations objectively and subjectively. Whether, and which, repair work had previously been necessary to fulfil these contractual obligations was not something the defendant had to tell the claimant.”

OLG München, final judgment of 1 July 2026, 7 U 2446/24, para. 31 — our translation

The reasoning is this: the buyer pays for a car free of defects and received exactly that. How the dealer got it into that condition is the dealer’s business. Things would be different if the repair revealed a circumstance that permanently reduces the car’s value, such as accident damage. The buyer did not rely on that, however, and alleged neither an accident nor a loss of market value. Rescission was not an option either, because the car had no defect.

Notably, the buyer did win a procedural point. The Regional Court had dismissed her allegations about the extent of the work as speculation “ins Blaue”, a shot in the dark. The Higher Regional Court disagreed: a buyer who lists the work done, submits the car’s repair history and offers an expert report as evidence pleads with sufficient precision (para. 27). It just did not help her, because even if her allegations were taken as true, they gave no ground for avoidance.

Why was the case already decided at first instance?

Because the appeal court is, as a rule, bound by the findings of fact made at first instance. It establishes the facts anew only where specific indications raise doubts about their accuracy or completeness (section 529 (1) no. 1 of the German Code of Civil Procedure, ZPO). The court stressed that repeating the taking of evidence is not at the appeal court’s free discretion and comes into question only where there is a certain likelihood that the first-instance findings will turn out to be wrong. The first-instance court assesses evidence according to its free conviction (section 286 (1) ZPO) and may believe a witness even where individual circumstances could raise doubts.

For buyers this means that the examination of the salesman at first instance is the decisive moment of the whole case. A buyer who has no evidence of his or her own at that point, such as chat histories, the advert, a person who came along as a witness or written answers to specific questions, stands little chance against a confident salesman in the witness box. This cannot be fixed on appeal.

How do I avoid a car purchase for fraud, and what do I get back?

You declare avoidance to the seller (section 143 (1) BGB), for evidential reasons in writing and with proof of receipt. Describe the deceit specifically and, as a precaution, declare rescission at the same time if warranty rights still exist. The one-year period runs from the day you discover the deceit (section 124 (2) first sentence BGB), for example from the garage diagnosis or the expert report that reveals the concealed accident damage. The Munich court left open whether the buyer there had met this deadline. Be careful about negotiating a discount once you know of the deceit: a buyer who confirms the contract knowing the ground for avoidance loses the right to avoid (section 144 (1) BGB).

If the avoidance is effective, you paid the price without legal grounds and can claim it back (section 812 (1) first sentence, first alternative BGB). In return the dealer can demand the car back and compensation for the kilometres driven, concurrently against repayment (sections 812 (1) and 818 (2) BGB, BGH, judgment of 7 June 2006, VIII ZR 209/05, paras. 28 and 29). The deceived buyer has one important advantage: he or she can claim the price back even if the car was damaged or destroyed while in the buyer’s hands and can only be returned in a reduced state or not at all (BGH, judgment of 8 January 1970, VII ZR 130/68, BGHZ 53, 144, headnote 1). In such cases the Federal Court of Justice examines avoidance and rescission side by side (BGH, VIII ZR 209/05, para. 7), so it pays to declare both.

Frequently asked questions

Does the dealer have to tell me the car was a rental car?
The courts are not unanimous. The Higher Regional Court of Stuttgart found a duty to disclose for a young car that had been used exclusively as a rental car by its first owner (19 U 54/08), other courts take a narrower view. A clear entry in the sales contract is in any event sufficient, as the Higher Regional Court of Munich held on 1 July 2026 (7 U 2446/24). If in doubt, ask specifically, a false answer is active deceit.

The dealer repaired the car before handover without telling me. Can I avoid the contract?
As a rule not, if the car was free of defects on handover. The Higher Regional Court of Munich found no duty to disclose repair work between the contract and handover, even assuming work on the cylinder head, camshaft and axles. It may be different if the repair concerned accident damage that permanently reduces the car’s value.

How long do I have to avoid a car purchase for fraud?
One year from the time you discover the deceit, but no more than ten years after you made your declaration to buy (section 124 BGB). The two-year limitation period for warranty claims plays no role for avoidance.

Does avoidance help if the contract contains “gekauft wie gesehen”?
Yes. A warranty exclusion only concerns warranty rights, not avoidance under section 123 BGB. In addition, a seller who fraudulently concealed a defect cannot rely on the exclusion (section 444 BGB). You do, however, have to prove the deceit.

What do I have to prove?
The deceit, your mistake, that the deceit influenced your decision to buy, and the seller’s intent. Written evidence carries more weight than your recollection, because the salesman will usually testify as a witness for his employer.

I live outside Germany and bought the car from a German dealer. Can you represent me?
Yes. We review the contract, the advert and the correspondence, declare avoidance and rescission to the dealer and conduct the proceedings before the German court, in English, German and Polish. You can send us your documents online.
