Can I complain about hidden defects in a car I bought?
Yes: the seller is liable for a car's hidden defects under the statutory warranty. Buying a car (including used) from a private person, you're protected by the Civil Code warranty — the seller is liable for physical defects, including hidden ones (e.g. a crash history, hidden faults), as a rule for 2 years from delivery. Between private persons the warranty can be contractually limited or excluded (the popular "the buyer checked the condition" clause), but such exclusion is ineffective if the seller deceitfully concealed the defect. You can demand a price reduction, a repair, or withdraw from the contract (for a material defect) and get your money back. Buying from a dealer (a business) as a consumer, you have protection for non-conformity of goods with the contract. Claims must be raised in time after discovering the defect.
📋 The rules
- The seller is liable for hidden defects under the warranty
- Liability period: as a rule 2 years from delivery
- Excluding the warranty is ineffective on deceitful concealment
- Demands: price reduction, repair or withdrawal
- From a dealer: protection for non-conformity with the contract
🔓 Exceptions
- Contractual exclusion of the warranty between private persons: valid, but not on concealment
- Defects the buyer knew of at purchase: outside liability
- Buying from a business: consumer rules apply (not the Civil Code warranty)
⚠️ Penalties & fines
The hardest part is often the proof — the buyer usually must show the defect existed before the sale and was hidden; an expert opinion helps. The clause "the buyer has examined the technical condition" doesn't release the seller from liability for deceitfully concealed defects. If the seller refuses to recognise the claims, the case can go to court, and for deliberate fraud criminal liability also applies. To complain about hidden defects effectively: gather documentation (contract, listing, correspondence, expert opinion), promptly after discovering the defect file a demand with the seller (in writing), state the basis (warranty or non-conformity), and on refusal pursue your rights in court. Before buying, always check the vehicle's history and have a mechanic inspect it.

❓ Frequently asked
Can I complain about hidden defects in a used car?
Yes. The seller is liable for physical defects, including hidden ones, under the warranty — as a rule for 2 years from delivery. You can demand a price reduction, a repair, or withdraw from the contract for a material defect. This applies to buying from a private person and a business alike.
Does a clause about checking the car release the seller?
Not always. Between private persons the warranty can be contractually limited or excluded, e.g. by a clause that the buyer examined the technical condition. But such exclusion is ineffective if the seller deceitfully concealed the defect. Then, despite the clause, they're liable for hidden faults.
What can I demand for a hidden defect?
Under the warranty you can demand a price reduction or a repair, and for a material defect — withdraw from the contract and recover the amount paid. The choice of rights depends on the situation and the nature of the defect. Buying from a business, the non-conformity rules apply.
How do I prove a hidden car defect?
Usually the buyer must show the defect existed before the sale and was hidden. An expert opinion and documentation help: the contract, the listing's content, correspondence with the seller. It's also worth checking the vehicle's history in advance and having a trusted mechanic inspect it.
What if the seller rejects the complaint?
First file a demand in writing, stating the basis and describing the defect. If the seller refuses, you can take the case to the civil court. For deliberately misleading about the car's condition, the seller can also face criminal liability for fraud. Keep all the evidence.
