I have had my car for only a few days and already I am having problems with it. Can I just return it to the dealership?

No. Problems can occur immediately, but if you are interested in opening a Pennsylvania Lemon Law claim, you must follow proper procedures. That means making an appointment to have your car examined and repaired, and securing a repair invoice when you pick up your car. Make sure the invoice properly outlines all of the problems you disclosed to the service manager.
