Can I reject a used car within 30 days?
If you bought a used car from a UK dealer and a fault appears within 30 days, your options may depend on when the fault appeared, whether it was present or developing at purchase, what the seller told you, and what evidence you have.
Plain English explanation
The short-term right to reject under the Consumer Rights Act 2015 typically applies to faults appearing in the first 30 days.
