This needs to be reported to The National Highway Traffic Safety Administration (NHTSA) via their website.
Then, telephone the Saturn/GM customer care people (contact info is contained in your Owner’s Manual), inform them of what has transpired with the vehicle, and also report that you have filed an incident report with NHTSA.
Ask the customer car people how to proceed with this problem. They will likely schedule an appointment with the GM Zone Representative, as even failing corporations are averse to law suits based on defective products.
Also, begin educating yourself about the details of the Lemon Law in your state. In most states, the dealership gets three attempts to rectify a problem, but this could vary, depending on the state.
