Which rules apply to a used car purchase depends on who sold it: consumer legislation where you buy from a dealer, the general provisions where you buy privately. Where the seller knowingly concealed the defect — fraudulent concealment — they cannot rely on the time limits, and that is the buyer's strongest ground.
Used vehicle sales generate more consumer disputes than almost any other area, and the two recurring complaints are clocked mileage and concealed damage history.
Dealer or Private Seller?
From a dealer (a commercial business): the seller is a "seller/supplier" and the buyer a "consumer", and Act No. 6502 applies. That is a much stronger position for the buyer.
The Regulation on the Trade in Second-Hand Motor Vehicles also obliges licensed businesses to have an inspection report prepared and to inform the buyer of the vehicle's condition before sale.
From a private seller: there is no consumer relationship, so Act No. 6502 does not apply and the Code of Obligations governs the sale. The competent court is the civil court of first instance.
The buyer is not unprotected there either: TBK arts. 219 ff. govern the warranty against defects.
| From a dealer | From a private seller | |
|---|---|---|
| Applicable law | Consumer legislation | General provisions (TBK) |
| Forum | Arbitration committee / consumer court | Civil court of first instance |
| Liability period | 2 years as a rule | 2 years as a rule |
| Where the defect was concealed by fraud | The time limit does not apply | The time limit does not apply |
| Inspection report required | Required of the seller | Not required |
| Ease of proof | Relatively high | Relatively low |
A "sold as seen" clause gives no protection in respect of defects the seller knowingly concealed.
The Warranty Against Defects
TBK art. 219: the seller is liable both for the absence of qualities they represented and for material, legal or economic defects that remove or substantially reduce the value of the thing for its intended use, or the benefits the buyer expected of it.
The seller is liable even if unaware of those defects.
The buyer's alternative remedies (TBK art. 227):
- Rescission, declaring readiness to return the vehicle;
- Keeping it and claiming a reduction in the price proportionate to the defect;
- Free repair at the seller's cost, where it does not require excessive expense;
- Replacement with a defect-free equivalent, where possible.
The buyer's right to claim damages under the general provisions is reserved.
TBK art. 223 also requires the buyer to examine the vehicle as soon as the ordinary course of business allows and, on finding a defect for which the seller is liable, to notify them within a reasonable period.
Why Fraud Is the Strongest Ground
Clocking the mileage and concealing serious damage go beyond a simple defect: they amount to fraudulent concealment, with two consequences.
First, no limitation period runs. TBK art. 231: unless the seller undertook a longer period, any action arising from a defect is time-barred two years after the vehicle is transferred, even if the defect appears later. But a seller who concealed the defect by gross fault cannot rely on the two-year period.
Act No. 6502 art. 12 adopts the same principle for consumer transactions: where a defect was concealed by gross fault or fraud, the limitation provisions do not apply.
Second, the contract can be annulled. TBK art. 36: a party who entered a contract as a result of the other's deception is not bound by it, even if the mistake was not fundamental. Annulment for deception must be notified within one year of discovering it (TBK art. 39).
Fraud may also constitute the offence of fraud, and can be the subject of a criminal complaint.
How It Is Proved
- Insurance damage records. They show the damage history and should be checked before purchase.
- Authorised service records. The mileage entered at each service exposes clocking.
- Vehicle inspection station records. Mileage is recorded at every inspection and past records can be compared.
- An inspection report. Paint thickness measurement, chassis check, mechanical examination.
- The advertisement. Statements in the listing form part of the contract; keep a screenshot.
- Correspondence containing the seller's assertions that the vehicle was "undamaged" or "original".
Preservation of evidence before filing is highly effective: the vehicle's condition and the nature of the defect are established by the court.
The expert examination also determines the difference in value between the vehicle as it is and as it should have been, which is the basis of a price reduction claim.
What to Do
- Notify immediately on discovering the defect — in writing and dated; a notarised warning notice is safest.
- Obtain preservation of evidence before any work is done on the vehicle.
- Choose your remedy. Rescission or price reduction? State the claim clearly.
- If you bought from a dealer: apply to the consumer arbitration committee or the consumer court according to the value. Consumer actions are exempt from court fees.
- If you bought privately: file in the civil court of first instance, checking whether mediation is a condition where the dispute is commercial.
- Where there is fraud, make a criminal complaint. The criminal file also strengthens the civil case.
- Administrative complaint. For licensed businesses, a report can be made to the Ministry of Trade.
A final warning: clauses such as "the vehicle has been seen and accepted, no liability is accepted" do not relieve the seller of liability for concealed defects. Under TBK art. 221 an agreement excluding or limiting liability for defects is void where the seller concealed the defect by fraud.
Under TBK art. 221, an agreement excluding the seller's liability for defects is void where the defect was concealed by fraud. And where a defect was concealed by gross fault, the seller cannot rely on the two-year limitation period. Clocking and concealed damage fall within this.
Frequently Asked Questions
Does it matter whether I bought from a dealer or privately?
Yes. From a dealer, Act No. 6502 and the consumer forums apply; privately, the Code of Obligations and the civil court of first instance.
The mileage was clocked but two years have passed.
Where a defect was concealed by gross fault or fraud, the two-year limitation period cannot be relied on.
Can I return the vehicle?
Rescission is one of the alternative remedies, along with a price reduction, free repair and replacement. The choice is yours.
How do I prove it?
Insurance damage records, service and inspection station mileage records, an inspection report, the advertisement and the seller's statements in correspondence.
Is the exclusion clause in the contract valid?
Not against a seller who concealed the defect by fraud; it does not relieve them of liability.
