Can a car be returned to dealership if within 4 days of purchase there is major problems with the engine Ohio?

Yes it can be returned. However, what will happen is the dealership will insist they have their technicians look over the engine and run a computer diagnostic check depending on what type of engine issues you are having and, Chances are, they will 'not find anything wrong with the engine.' In this case, you insist they look over the car again and keep bringing it back to the dealer. Once you keep records, under the lemon law, you can send in a complaint This could be a simple fix depending on what type of engine problems. A friend of mine had a brand new car and after having major issues with the engine, had it returned and exchanged for another car. Hope this helps
