Faulty Used Car in Spain? Warranty and Hidden-Defect Claims

Bufete Padilla Torrevieja · Civil and consumer law · 11 November 2026

Buying a second-hand car in Spain and then discovering engine failure, defective brakes or misleading mileage can lead to an expensive dispute. Not every breakdown entitles you to return the car, but a seller cannot necessarily escape liability by saying it is used or sold without a warranty.

> Short answer: a private sale normally falls under the Spanish Civil Code, with a general six-month period from delivery for hidden-defect claims. If you buy as a consumer from a dealer, statutory conformity protection normally lasts three years; a valid agreement may reduce this for used cars, but never below one year. The cause and seriousness of the defect, your contract and the evidence determine the available remedy.

1. Private seller or professional dealer: which rules apply?

Check who signed the contract, took payment, advertised the car and negotiated the sale. An intermediary is not automatically the seller. Equally, someone actually operating a professional car-selling business cannot necessarily avoid consumer law by describing themselves as a private individual.

• Private sale: the Civil Code generally applies. The buyer normally proves that the defect was hidden, serious and already present at sale.
• Dealer-to-consumer sale: the TRLGDCU provides statutory conformity protection, no-cost remedies and evidential presumptions.
• Business purchase: consumer protection is not automatic. A self-employed person buying for personal use may qualify; a commercial company buying for its business generally does not. Article 3 also covers certain non-profit entities acting outside a commercial or business activity.

2. Hidden defect or ordinary wear and tear?

Article 1484 of the Civil Code concerns a defect that existed at sale, was not apparent and makes the car unsuitable for its intended use or so reduces its usefulness that the buyer would not have purchased it, or would have paid less.

Possible examples requiring evidence: a pre-existing engine crack temporarily concealed, serious internal gearbox damage or undisclosed structural accident damage. A failure soon after delivery warrants investigation but does not alone prove it existed beforehand.

Wear is not automatically a hidden defect. Age, mileage, price, maintenance, disclosure and expected component life matter. Tyres, clutches and batteries are neither automatically excluded nor always covered. Distinguish expected wear from an abnormal pre-existing defect or an unfulfilled specific promise.

A private seller can be liable even without knowing about the defect (Article 1485). Any exclusion clause needs scrutiny: it cannot protect a seller who knew of and concealed the problem. Article 1484 also addresses apparent defects and those a buyer should recognise because of their professional expertise.
