Bought from a dealer? Strong rights
From a trader, the Consumer Rights Act 2015 says the car must be of satisfactory quality, fit for purpose and as described. If it’s faulty:
- First 30 days: you can reject it for a full refund — including the return of any part-exchange.
- After 30 days: you must give the dealer one chance to repair or replace it; if that fails, you can claim a price reduction or a final rejection.
- The fault must be beyond normal wear and tear and have been there (or developing) when you bought it.
