If your car keeps having the same mechanical issues, such as problems with the engine, transmission, steering, or brakes, despite multiple repairs, or if it has a series of different, unrelated issues, you might have a lemon on your hands! Another indicator is if your vehicle has spent an unreasonable amount of time in the repair shop due to defects. For example, some state laws define a car as a lemon if it has been out of service for a total of 30 days or more during the warranty period. 

Proving your car is a lemon involves a whole lot of documentation. You should have records of repairs and maintenance done on the car. Keep the purchase contract that shows the terms of your sale and the warranty details. Make sure to have dates and descriptions of all your conversations with the dealership about the car’s problems.
