Introduction
Defective goods are among the most common sources of consumer disputes in Turkey. A consumer may purchase a mobile phone that repeatedly shuts down, a washing machine that does not function properly, furniture delivered with structural defects, a vehicle with hidden mechanical problems, or an electronic product that does not match the features advertised by the seller. In such cases, Turkish Consumer Law provides strong protection to the buyer.
The main legal framework is Law No. 6502 on the Protection of Consumers, which regulates defective goods, defective services, unfair contract terms, distance sales, warranty rights, after-sales services, consumer arbitration committees, and consumer courts. Under this legal system, sellers are not free to ignore consumer complaints or force consumers into a remedy that is contrary to the law.
Defective goods are specifically regulated under Articles 8 to 12 of Law No. 6502. The law defines what constitutes a defective good, explains the seller’s liability, regulates the burden of proof, grants consumers elective rights, and sets limitation periods. The Ministry of Trade also provides public guidance explaining that consumers may request refund, replacement, price reduction, or free repair in defective goods disputes.
For consumers, knowing these rights is essential. For sellers, importers, manufacturers, and authorized service providers, understanding these rules is equally important because non-compliance may lead to refund obligations, replacement duties, compensation claims, administrative complaints, reputational damage, and litigation before Consumer Arbitration Committees or Consumer Courts.
What Is a Defective Good Under Turkish Consumer Law?
A defective good is not limited to a product that is completely broken. Under Turkish Consumer Law, a good may be defective if it does not conform to the contract, does not match the agreed sample or model, lacks the objective characteristics that it should normally have, or contains material, legal, or economic deficiencies that reduce or remove the expected benefit for the consumer.
For example, a refrigerator that fails to cool, a mobile phone with a faulty battery, a television with display problems, a sofa delivered with broken parts, a laptop with different technical specifications than advertised, or a vehicle with hidden engine problems may be considered defective.
Law No. 6502 also treats certain failures as non-conforming performance. If the seller fails to deliver the good within the contractual period, or if the product is installed incorrectly by the seller or under the seller’s responsibility, this may be considered a defective performance. If the consumer is expected to install the product but the installation is defective because the instructions are wrong or incomplete, this may also fall within the defective goods regime.
This broad definition is important because sellers sometimes argue that a product is not defective merely because it is still partially usable. That argument is not always sufficient. A product may still be legally defective if it does not provide the ordinary benefit expected from that type of product, does not match the seller’s representations, or contains a deficiency that reduces its value or usability.
Types of Defects: Material, Legal, and Economic Defects
Defects may appear in different forms. The most obvious type is a material defect. This refers to physical, technical, or functional problems in the product. A cracked screen, faulty motor, broken mechanism, manufacturing error, missing part, or repeated malfunction may constitute a material defect.
A second category is a legal defect. This may arise where the consumer cannot legally use the product as expected. For example, a product sold without legally required documentation, a vehicle with title or registration problems, or a product that cannot be legally placed on the market due to regulatory non-compliance may involve a legal defect.
A third category is an economic defect. This occurs where the product’s economic value is reduced due to a deficiency. For example, if a product is advertised as new but is actually refurbished, previously used, damaged, or missing essential features, the consumer may argue that the product has an economic defect even if it technically functions.
The practical importance of these categories is that a defective goods claim should not be limited to physical breakdown. A product may be defective because of misinformation, missing legal qualities, reduced market value, incorrect specifications, or non-compliance with advertising promises.
Seller’s Liability for Defective Goods
The seller is under a legal duty to deliver the product in conformity with the contract. If the product is defective, the seller may be held liable even if the seller did not personally manufacture the product. In consumer law, the consumer usually deals directly with the seller, and the seller cannot easily avoid responsibility by blaming the manufacturer, importer, cargo company, or authorized service.
In practice, sellers often try to direct consumers to authorized service providers. While technical inspection may be necessary in some cases, this does not remove the seller’s legal responsibility. The consumer’s rights arise from the sales contract and from Law No. 6502. Therefore, the seller must take the consumer’s request seriously and cannot automatically reject refund, replacement, or repair requests without proper legal and technical basis.
Depending on the chosen remedy, the manufacturer or importer may also become relevant, especially in replacement and repair disputes. For example, if the consumer requests free repair and the request is not fulfilled, the seller, manufacturer, and importer may face joint responsibility under the consumer protection framework.
The Consumer’s Four Elective Rights
When a product is defective, Turkish Consumer Law grants the consumer four main elective rights. These rights are central to defective goods disputes:
- Withdrawal from the contract and refund
- Keeping the product and requesting a price reduction
- Free repair at the seller’s expense, provided it does not require excessive cost
- Replacement with a defect-free equivalent, if possible
The Ministry of Trade’s consumer guidance confirms that consumers may use these elective rights in defective goods cases.
These are called “elective rights” because the consumer is generally allowed to choose among them. The seller cannot simply impose repair if the consumer lawfully requests refund or replacement. However, the exercise of these rights may be affected by proportionality, impossibility, the nature of the product, the seriousness of the defect, and whether the requested remedy creates disproportionate difficulty for the seller.
For this reason, the legal strategy should be determined according to the facts of each case. A minor cosmetic defect may justify price reduction or repair, while a serious hidden defect in a vehicle may justify rescission and refund. A recurring defect after repeated repairs may strengthen the consumer’s position when requesting replacement or refund.
Refund Right: Withdrawal from the Contract
The refund right is one of the most powerful remedies available to consumers. It is legally framed as withdrawal from the contract. In practical terms, the consumer returns the defective product and requests repayment of the sale price.
A refund claim is especially relevant where the defect is serious, the product cannot be used for its intended purpose, the consumer has lost confidence in the product, or repair attempts have failed. For example, if a newly purchased vehicle repeatedly breaks down due to a serious mechanical problem, or if a household appliance cannot perform its essential function despite service intervention, the consumer may argue that refund is the appropriate remedy.
The refund request should be clear and written. The consumer should state that the product is defective, explain the defect, indicate the purchase date, attach evidence, and expressly request withdrawal from the contract with repayment of the sale price.
From the seller’s perspective, rejecting a refund request requires more than a general denial. The seller should provide a reasoned technical explanation and supporting evidence. If the defect appeared within the first six months after delivery, the burden of proof rule may make the seller’s position more difficult.
Replacement Right: Requesting a Defect-Free Product
Replacement is another important remedy. If possible, the consumer may request that the defective product be replaced with a defect-free equivalent. This remedy is common in electronics, white goods, furniture, vehicles, mobile phones, computers, and other consumer products.
Replacement may be more appropriate than refund where the consumer still wants the product but does not want to keep a defective unit. For example, if a consumer buys a new laptop and the device has a manufacturing defect shortly after delivery, replacement may be a reasonable solution.
However, replacement may not always be possible. If the product is no longer produced, is out of stock, is unique, or replacement would impose disproportionate difficulty, the seller may argue that another remedy should be applied. Law No. 6502 recognizes proportionality considerations where free repair or replacement would create disproportionate difficulty for the seller. In such circumstances, refund or price reduction may become more realistic alternatives.
The replacement request should also be made in writing. The consumer should avoid vague expressions such as “solve my problem” and instead clearly state: “I request replacement of the defective product with a defect-free equivalent under my elective rights arising from Law No. 6502.”
Free Repair Right
Free repair is frequently used in defective goods disputes, especially for electronics, white goods, furniture, vehicles, and technical products. If the consumer chooses repair, the seller must ensure that the defect is corrected without charging the consumer, provided that repair does not require excessive cost.
Free repair includes labor, parts, transportation, and other necessary expenses connected to eliminating the defect. A seller or authorized service should not impose additional charges on the consumer for a defect covered by the legal remedy.
However, repair must be effective. A repair process that repeatedly fails, takes an unreasonable time, or does not eliminate the defect may not adequately protect the consumer. In such cases, the consumer may later rely on other remedies such as replacement or refund, depending on the facts.
Consumers should keep all service forms and repair records. These documents are very important because they show the history of the defect, the number of repair attempts, the dates of service applications, and whether the problem continued. In many defective product disputes, repeated service records become the strongest evidence in favor of the consumer.
Price Reduction Right
Price reduction allows the consumer to keep the product but request a reduction in the sale price proportionate to the defect. This remedy is useful where the product is still usable but its value is lower than promised.
For example, if furniture is delivered with a visible but non-critical defect, or if a product has a missing feature that reduces its value but does not make it unusable, price reduction may be suitable. It may also be appropriate where refund or replacement would be disproportionate but the consumer should not be expected to pay the full price for a defective product.
The amount of reduction should be determined according to the difference between the value of the product as promised and the value of the product in its defective condition. In court proceedings, expert examination may be required to calculate this difference.
From a legal drafting perspective, a price reduction claim should be supported by photographs, market value comparisons, technical reports, invoices, and expert opinions where possible.
Burden of Proof in Defective Goods Cases
The burden of proof is one of the most important issues in defective goods disputes. Under Law No. 6502, defects that appear within six months from delivery are presumed to have existed at the time of delivery. In that situation, the seller must prove that the product was not defective. This presumption does not apply if it is incompatible with the nature of the product or the defect.
This rule provides significant protection to consumers. Without it, consumers would often struggle to prove that a technical defect existed at the time of delivery, especially in products such as electronics, appliances, or vehicles. The six-month presumption shifts the evidentiary burden to the seller and requires the seller to produce convincing technical evidence.
After six months, the consumer may still bring a defective goods claim, but proving that the defect is legally attributable to delivery may become more difficult. This is why early documentation is critical. Consumers should not delay complaints, service applications, or legal notices.
Hidden Defects and Repeated Malfunctions
Some defects are obvious at delivery, such as broken packaging, missing parts, or visible physical damage. Others are hidden and appear only after use. Hidden defects are common in vehicles, electronics, machinery, furniture mechanisms, heating systems, and household appliances.
A hidden defect may still give rise to consumer rights if it existed at delivery or is legally presumed to have existed at delivery. The fact that the consumer discovered the problem later does not automatically remove the seller’s liability.
Repeated malfunctions are especially important. A product that fails again and again may show that the underlying defect was not properly resolved. In such cases, the consumer may argue that repair is no longer a sufficient remedy and that replacement or refund is necessary to restore contractual balance.
A strong repeated-defect claim should include a chronological table of service applications, repair dates, fault descriptions, service reports, and evidence showing that the same or related defect continued.
Warranty Documents and Statutory Rights
Many consumers believe that warranty rights and statutory rights are the same. They are related but not identical. A warranty certificate may provide additional procedural and technical protections, but it does not eliminate the consumer’s statutory rights under Law No. 6502.
A seller or service provider cannot reject a valid defective goods claim merely by referring to warranty limitations if the consumer is exercising statutory rights. Similarly, a warranty period does not necessarily determine all legal consequences of defective goods. The consumer’s rights must be assessed under the relevant provisions of consumer law, limitation periods, warranty rules, and the facts of the case.
Warranty disputes often arise when authorized services claim “user error.” This defense must be supported by objective technical findings. A vague service report stating “user fault” without explaining the mechanism, cause, and evidence may be challenged. Consumers should request detailed service reports and, where necessary, seek independent technical evaluation.
Limitation Periods for Defective Goods
Limitation periods are critical in defective goods claims. As a general rule, unless a longer period is provided by law or contract, liability for defective goods is subject to limitation periods that run from delivery. For movable goods, the commonly applied limitation period is two years; for immovable property used for residential or holiday purposes, longer periods may apply.
However, limitation rules can be complex. The type of product, nature of the defect, whether the defect was hidden, whether there was fraudulent concealment, warranty documents, service applications, and contractual provisions may all affect legal analysis.
Consumers should therefore act quickly. Waiting too long may weaken both the evidentiary position and the legal position. Businesses should also preserve records during the relevant limitation periods because service forms, delivery documents, inspection records, and correspondence may later become decisive evidence.
Evidence Needed for a Defective Goods Claim
Evidence is often the decisive factor in defective goods disputes. A consumer may be legally right, but if the claim is not properly documented, the dispute may become harder to prove.
Important evidence includes:
- Invoice or receipt
- Sales contract
- Warranty certificate
- Delivery document
- Cargo record
- Product photographs and videos
- Service forms
- Authorized service reports
- Written complaints
- Emails and messages with the seller
- Call center records, if available
- Bank or credit card payment records
- Screenshots of advertisements or product descriptions
- Expert reports, where necessary
For online purchases, screenshots are especially important. Product pages, technical specifications, campaign statements, delivery promises, seller identity, and return conditions may change after the purchase. A consumer who preserves screenshots from the purchase date will usually be in a stronger position.
Consumer Arbitration Committees in Defective Goods Disputes
For many defective goods disputes, the first legal forum is the Consumer Arbitration Committee. These committees provide a relatively accessible and cost-effective mechanism for resolving consumer disputes.
For 2026, consumer disputes with a value below TRY 186,000 fall within the application scope of Provincial or District Consumer Arbitration Committees. The Ministry of Trade announced that this threshold applies from 1 January 2026.
A defective goods application should include a clear factual summary, the purchase date, product details, defect description, evidence list, correspondence with the seller, and the chosen remedy. The consumer should clearly state whether the request is refund, replacement, free repair, or price reduction.
A weak application usually contains emotional complaints but lacks legal structure and evidence. A strong application explains the defect, connects it to Law No. 6502, proves the purchase relationship, documents the defect, and makes a precise legal request.
Consumer Courts and Mediation
If the dispute exceeds the Consumer Arbitration Committee threshold or falls outside the committee’s authority, the dispute may need to proceed before Consumer Courts. In locations where there is no separate Consumer Court, the competent civil court may hear the case in the capacity of a Consumer Court.
For many consumer disputes that must be filed before court, mandatory mediation may be required before litigation. This procedural step is important because filing a lawsuit without completing mandatory mediation may result in procedural problems.
Consumer Court cases involving defective goods often require expert examination. This is especially common in vehicle disputes, electronic goods, construction-related consumer products, expensive furniture, appliances, and technical products. The expert report may determine whether the product is defective, whether the defect is user-related, whether repair is possible, and which remedy is proportionate.
Defective Vehicles Under Turkish Consumer Law
Vehicle disputes are among the most serious defective goods cases because the financial value is high and technical issues may affect safety. A defective vehicle may involve engine problems, transmission defects, electronic faults, paint defects, hidden accident history, mileage manipulation, or recurring mechanical failures.
In vehicle cases, expert examination is usually essential. The consumer should preserve service records, inspection reports, expert reports, advertisements, messages with the seller, payment records, and vehicle history documents. If the defect appeared shortly after delivery, the six-month presumption may be particularly important.
A refund claim in a vehicle dispute must be carefully structured. The petition should explain why the defect is serious, why the consumer cannot be expected to continue using the vehicle, whether repair attempts failed, and how the defect affects safety, value, and ordinary use.
Defective Electronics and Household Appliances
Electronics and household appliances frequently generate defective goods claims. Phones, computers, televisions, refrigerators, washing machines, dishwashers, ovens, and air conditioners may develop technical defects shortly after purchase.
Common problems include repeated shutdowns, overheating, battery failure, display defects, motor failure, software instability, sensor problems, excessive noise, or failure to perform basic functions.
In these disputes, consumers should avoid relying only on verbal statements from service personnel. Written service reports are critical. If the product is sent to service more than once, every form should be preserved. A repeated technical defect may justify a stronger remedy than simple repair.
Defective Goods in Online Sales
Online purchases create additional legal issues. The product delivered may differ from the online description, lack advertised features, arrive damaged, be counterfeit, be previously used, or fail shortly after delivery.
In online defective goods disputes, the consumer should preserve the product page, order confirmation, invoice, cargo delivery record, unpacking photos or videos, messages with the seller, and return request records. If the seller is on an online marketplace, the consumer should also document marketplace complaint records.
Online sellers must ensure that product descriptions, photographs, technical features, stock information, delivery promises, and warranty statements are accurate. Misleading online representations may strengthen the consumer’s defective goods claim.
Practical Steps for Consumers
A consumer who receives a defective product should act systematically. First, the defect should be documented with photographs and videos. Second, the invoice, warranty certificate, delivery documents, and product descriptions should be preserved. Third, the seller should be notified in writing. Fourth, the consumer should choose the preferred remedy clearly.
The notification should not be vague. Instead of saying “I am not satisfied,” the consumer should say: “The product is defective because of the following reasons. Under Law No. 6502, I exercise my elective right and request refund/replacement/free repair/price reduction.”
If the seller refuses or remains silent, the consumer should evaluate whether to apply to the Consumer Arbitration Committee or proceed through mediation and Consumer Court, depending on the dispute value and legal route.
Practical Steps for Sellers and Businesses
Businesses should treat defective goods complaints seriously. A legally weak complaint-handling process can transform a small customer issue into a formal dispute. Sellers should record the complaint, inspect the product, obtain technical reports where necessary, respond in writing, and avoid unsupported allegations of user error.
Businesses should also train customer service teams. Employees should understand that statutory consumer rights cannot be eliminated by internal store policies. A sign saying “no refunds” does not override mandatory consumer protection rules.
Good compliance requires accurate product descriptions, proper delivery records, valid warranty documents, transparent return procedures, clear service forms, and legally reviewed customer communication templates.
Why Legal Assistance Matters
Defective goods disputes may appear simple, but they often involve technical evidence, expert reports, limitation periods, warranty rules, burden of proof issues, and procedural requirements. Legal assistance can help determine the correct remedy, prepare the application, organize evidence, and respond to seller defenses.
For consumers, a lawyer can help frame the claim persuasively and avoid procedural mistakes. For businesses, legal support can reduce exposure, improve compliance, and help distinguish valid consumer claims from unsupported complaints.
High-value disputes, especially vehicle cases, expensive electronics, luxury goods, real estate-related consumer products, and repeated service failures, should be handled with particular care.
Conclusion
Defective goods under Turkish Consumer Law are not limited to completely unusable products. A product may be defective if it does not conform to the contract, lacks promised or expected qualities, differs from advertisements or technical specifications, contains material, legal, or economic deficiencies, is delivered late, or is installed incorrectly under the seller’s responsibility.
Law No. 6502 gives consumers four key elective rights: refund, replacement, free repair, and price reduction. The correct remedy depends on the nature of the defect, seriousness of the problem, feasibility of repair or replacement, proportionality, evidence, and procedural route.
For consumers, the strongest strategy is early documentation, written notification, clear remedy selection, and timely legal action. For sellers and businesses, the safest approach is transparent sales practice, accurate advertising, effective complaint management, proper technical reporting, and compliance with mandatory consumer protection rules.
In Turkey, defective goods disputes can often be resolved through Consumer Arbitration Committees or Consumer Courts, depending on the value and nature of the dispute. Success depends on legal accuracy, strong evidence, and a well-structured claim or defense.
