Consumer Rights for Defective Cars | Lemon Law in Turkey
The automotive sector in Turkey constitutes one of the most dynamic areas of the economy in terms of both new and second-hand vehicle markets. This dynamism brings with it complex legal disputes. Since the purchase of a vehicle is a significant economic investment for the buyer, defects (“ayıp”) appearing after the sale can lead to serious financial losses and safety risks. The Turkish legal system has created a detailed normative infrastructure to minimize these risks and restore the contractual balance between the parties.
1. Legal Nature and Types of Defects
In legal terms, a “defect” is the state where the sold good (the vehicle) does not possess the qualities agreed upon by the parties at the time of the contract or delivery, or the presence of deficiencies that reduce or eliminate the expected benefit from the good. The seller’s liability for defects is not based on fault but is an objective liability arising from the law (warranty liability). In other words, the seller cannot escape liability by saying “I did not know about this defect.”
In legal doctrine and Supreme Court practices, defects are examined in three main categories:
-
Material Defect: Deficiencies in the physical structure of the vehicle. For example; engine oil burning, transmission failure, presence of painted or replaced parts on the bodywork, processed chassis, chronic failures in the braking system are within the scope of material defects.
-
Legal Defect: Legal restrictions preventing the transfer of ownership or use of the vehicle. For example; liens, pledges, or seizure annotations on the vehicle, the vehicle being stolen, or being a “change” (chassis number altered) vehicle are legal defects.
-
Economic Defect: Defects that reduce the economic value or efficiency of the vehicle. For example; fuel consumption being much higher than factory data, or the odometer being rolled back can be considered economic defects.
2. Liability for Defects Under the Turkish Code of Obligations (TBK)
The TBK, as a general law, determines the basic conditions of liability for defects. These provisions apply directly to sales between merchants or second-hand vehicle sales between two private citizens (non-consumers).
Limits of the Seller’s Liability
Turkish Code of Obligations Article 219
Article 219 – The seller is liable to the buyer for the absence of the qualities they declared in any way, as well as for the presence of material, legal, or economic defects that are contrary to the quality or quantity affecting the quality, which eliminate or significantly reduce its value and the benefits the buyer expects from it in terms of the purpose of use.
The seller is liable for these defects even if they were unaware of their existence.
Analysis and Insights:
When Article 219 of the TBK is examined, it is seen that the seller’s liability has two main bases: “Absence of promised qualities” and “Lack of necessary attributes.”
-
Promised Quality: The seller committing to a specific feature regarding the vehicle. For example, if the seller says “the vehicle is flawless, unpainted” but paint is found on the vehicle, this is a lack of promised quality.
-
Necessary Attribute (Objective Defect): Even if the seller makes no declaration, there are minimum standards expected from a vehicle (it runs, brakes work, etc.). Situations below these standards create liability regardless of the seller’s declaration. The legislator has strictly ruled with the phrase “liable even if unaware” that the seller’s good faith does not absolve them of responsibility.
Defects Known by the Buyer and Obligation to Inspect
Turkish Code of Obligations Article 222
Article 222 – The seller is not liable for defects known to the buyer at the time the sales contract was established.
The seller is also liable for defects that the buyer could have seen by sufficiently inspecting the sold item only if they have specifically undertaken that such a defect does not exist.
Analysis and Insights:
TBK Art. 222 regulates the concepts of “open defect” and “known defect.” If the buyer saw the scratch on the bodywork while purchasing or was told that the engine was defective, they cannot later claim rights based on this. The second paragraph regulates defects “visible upon inspection.” Here, an obligation to act prudently is imposed on the buyer. If the buyer could see the condition by examining the vehicle in an ordinary way (e.g., worn tires, cracked glass), the seller cannot be held liable unless they specifically guaranteed otherwise. This article forms the legal basis for clauses like “I saw and liked the vehicle in its current condition” added to notary contracts; however, this declaration is valid only for “open defects.”
3. Defective Vehicles in Consumer Law and Burden of Proof
The Law No. 6502 on the Protection of Consumers (TKHK) covers cases where the buyer is a “consumer” and the seller is a “professional/commercial seller” (dealer, gallery).
Law on Protection of Consumers Article 8
ARTICLE 8 – (1) A defective good is a good that is contrary to the contract because it does not comply with the sample or model agreed upon by the parties at the time of delivery to the consumer or does not possess the qualities it should objectively have.
(2) Goods that do not possess one or more of the features included in its packaging, label, manual, internet portal, or advertisements… are also considered defective.
Analysis and Insights:
TKHK Art. 8 expands the definition of defect to include “advertisements and announcements.” Information given by a car company in a TV commercial is considered part of the contract. Additionally, the term “internet portal” covers online vehicle sales listings. If a vehicle sold as “flawless” in the listing turns out to be painted, it directly results in a defective good under this article.
The Six-Month Presumption: The Consumer’s Strongest Tool
Law on Protection of Consumers Article 10
Article 10 – (1) Defects that appear within six months from the delivery date are considered to have existed on the delivery date. In this case, the proof that the good is not defective belongs to the seller. This presumption does not apply if it is incompatible with the nature of the good or the defect.
Analysis and Insights:
This article introduces a “presumption” that significantly strengthens the buyer’s hand in consumer transactions. If a malfunction occurs within the first 6 months after delivery, the law accepts the assumption that “this malfunction existed at the time of sale.” The burden of proof shifts to the seller. The seller must prove that this malfunction was caused by user error or did not exist at the time of sale.
4. Inspection and Notification of Defects
Our legal system ties the use of rights arising from defects to certain form and time conditions.
Notification Periods in the TBK Regime
Turkish Code of Obligations Article 223
Article 223 – The buyer must inspect the condition of the sold item they have taken over as soon as possible according to the ordinary course of business and, if they see a defect that requires the seller’s liability, must notify them within a reasonable time.
…If a defect that cannot be revealed by ordinary inspection exists… it must be notified to the seller immediately upon discovery.
Analysis and Insights:
-
Open Defects: Defects that can be noticed by ordinary inspection. Must be reported within a “suitable time.”
-
Hidden Defects: Defects that appear with use or expert examination. Must be reported “immediately” upon discovery. In Supreme Court practice, this is interpreted as the shortest reasonable time (usually 2-8 days) via notary notice.
Fraud and Gross Negligence Exception
Turkish Code of Obligations Article 225
Article 225 – The seller who is grossly negligent cannot relieve themselves of liability, even partially, by claiming that the defect in the sold item was not notified to them in time.
The same provision applies to defects that persons who have made selling their profession should know.
Analysis and Insights:
TBK Art. 225 refuses to protect the seller in cases of dishonesty. “Gross negligence” includes fraud. Odometer rollback is accepted as gross negligence/fraud by the Supreme Court. In this case, the seller cannot claim “lack of timely notification.” Furthermore, galleries and authorized dealers are expected to know the defects in the vehicles they sell due to their profession.
5. Optional Rights of the Buyer and Their Application
The buyer facing a defective vehicle is granted four basic optional rights in both laws.
Catalogue of Optional Rights
Turkish Code of Obligations Article 227 / Consumer Law Article 11
Rescission of the contract by declaring readiness to return the sold item (Refund).
Requesting a discount on the sales price in proportion to the defect.
Requesting free repair, provided it does not require excessive expense.
Requesting replacement with a defect-free equivalent.
Detailed Analysis of Rights
-
Rescission of Contract (Refund): The buyer returns the vehicle and demands the money paid with interest. In recent consumer law decisions, there is a strong jurisprudence unity that a “usage fee” cannot be deducted from the consumer returning the defective good.
-
Discount on Sales Price: The discount amount is not just the difference between “defect-free value” and “defective value.” The Supreme Court requires the Proportional Method. Formula: (Sales Price x Defective Value) / Defect-Free Value = Amount to be Paid.
-
Free Repair: Expenses belong to the seller. In consumer law, the repair period is a maximum of 30 working days.
-
Replacement with Defect-Free Equivalent:
-
Supreme Court Decision (Yargıtay HGK 2020/35 E., 2021/317 K.): The consumer requested a replacement due to a brake system failure in a new vehicle. The court ruled for replacement, stating that even if it could be fixed with simple repair, it was “trust-shattering” due to the vital importance of the brake system.
-
6. Statute of Limitations
Missing these periods leads to the loss of the right to sue.
Table 1: Statutory Limitation Periods
| Type of Sale | Legislation | Period | Starting Date |
| Consumer (New Car) | TKHK Art. 12 | 2 Years | Delivery Date |
| Consumer (Used Car) | TKHK Art. 12/2 | Min 1 Year (Usually 2) | Delivery Date |
| Ordinary Sale (TBK) | TBK Art. 231 | 2 Years | Transfer Date |
Statute of Limitations in Case of Gross Negligence and Fraud
If the defect is hidden by gross negligence or fraud (e.g., odometer tampering, hiding a total loss record), the 2-year statute of limitations does not apply. In this case, the general statute of limitations of 10 years applies.
7. Legal Liability of Expertise Firms
According to the 3rd Civil Chamber of the Supreme Court, expertise firms are jointly and severally liable with the seller for defects not stated in the report. The buyer can sue both the seller and the expertise firm for compensation. Liability is limited to the scope of the report (e.g., bodywork, engine).
8. 2026 Application Authorities and Limits
Correct determination of the authority is vital.
-
Consumer Arbitration Committees (2026 Limit): For disputes between 0 – 186,000 TL, application to District or Provincial Consumer Arbitration Committees is mandatory.
-
Consumer Courts: For disputes above 186,000 TL, a lawsuit must be filed in Consumer Courts. Mediation is a mandatory prerequisite before filing a lawsuit.
-
Commercial Courts: If both parties are merchants, the case is heard in Commercial Courts.
Conclusion and Roadmap for Buyers
-
Evidence Collection: Do not continue using the vehicle when a defect is noticed. Document the existence of the defect via authorized service records or court determination.
-
Notary Notice: After learning of a hidden defect, send a notice to the seller immediately (preferably within 2-8 days) specifying which optional right you are using.
-
Legal Process: If the seller does not respond positively, initiate the Arbitration Committee or Mediation process according to the 2026 limits.
-
Keep Records: Keep expertise reports, listing images, and service records. Remember that “sold as is” signatures do not bind you regarding hidden defects.
