Bought a Faulty Car From a Dealer UK

Bought a faulty car from a dealer? Understand your rights under the Consumer Rights Act 2015 including the 30-day short-term right to reject.

Last reviewed: 30 March 2026

Quick answer

When a car is bought from a dealer in England or Wales, the Consumer Rights Act 2015 generally requires it to be of satisfactory quality, fit for purpose, and as described. If it develops a fault within the first 30 days, the buyer may have a short-term right to reject the vehicle and obtain a full refund.

What this means in practice

Within the first 30 days of purchase, buyers may be entitled to a full refund if the car has a fault that was present at the time of sale or delivery. After 30 days but within six months, the dealer generally has one opportunity to repair or replace the vehicle before a refund can be requested, though any refund after the first six months might have a deduction for use. If the car was bought on finance, the finance company may be jointly liable under section 75 of the Consumer Credit Act 1974, provided the cash price was between £100 and £30,000. People often find it helpful to put complaints in writing and keep records of all faults and communications.

Common situations

Common situations include: a car developing mechanical faults shortly after purchase, a dealer refusing to accept responsibility for pre-existing issues, mileage discrepancies or clocking, a car described as having full service history when it does not, warning lights appearing within days of collection, and discovering outstanding finance on the vehicle after purchase.

What UK law says

The Consumer Rights Act 2015 (sections 9–11) requires goods sold by a trader to be of satisfactory quality, fit for a particular purpose, and as described. Section 22 provides a 30-day short-term right to reject. Sections 23–24 set out rights to repair, replacement, and price reduction. If the car was purchased on credit between £100 and £30,000, section 75 of the Consumer Credit Act 1974 may make the finance provider jointly liable. The Misrepresentation Act 1967 may also apply where false statements were made about the vehicle.

What people often consider

People in similar situations often consider: exercising the 30-day short-term right to reject, requesting a repair or replacement from the dealer, making a section 75 claim through their credit card provider or finance company, raising a complaint with the Motor Ombudsman if the dealer is a member, or pursuing the matter through the small claims court. Some people also explore whether an independent inspection report would strengthen their position.

Common mistakes to avoid

Common mistakes include: waiting too long and missing the 30-day rejection window, accepting verbal promises of repair without getting them in writing, continuing to drive the car extensively after discovering the fault (which may weaken a rejection claim), not obtaining an independent vehicle inspection to document faults, and not checking whether the dealer is a member of a trade body with a dispute resolution scheme.

Frequently asked questions

Can I return a faulty car to the dealer within 30 days?
Under the Consumer Rights Act 2015, there is generally a 30-day short-term right to reject goods that are faulty or not as described. This may entitle you to a full refund, though specific circumstances can vary.
What if the dealer says the car was sold as seen?
A 'sold as seen' notice does not generally override your statutory rights under the Consumer Rights Act 2015 when buying from a trader. The car still needs to be of satisfactory quality and as described.
Can I claim against the finance company for a faulty car?
If the car was bought using a credit agreement and the cash price was between £100 and £30,000, section 75 of the Consumer Credit Act 1974 may make the finance company jointly and severally liable for any breach of contract or misrepresentation.
Do my rights differ for a second-hand car?
The same statutory rights apply, but satisfactory quality takes into account the age, price, and mileage of the vehicle. A used car is not expected to be in the same condition as a new one, but it still needs to be roadworthy and as described.
