What do you do if the dealership where you purchased your vehicle does not honor the warranty?

If the dealership does not honor the warranty, there is usually a reason. Did the dealership give you a reason? If it was a new car such as one from General Motors or Chrysler, they may have closed the dealership. However, on new cars, the warranty is not from the dealer, but from the manufacturer. Another dealer that still has a contract with the manufacturer should be able to take care of it. If you damaged the car, that is not covered by warranty. The dealer does not need to take care of that. Otherwise, there should be someone at the local or state level who takes care of such problems. These people are paid to solve these kind of problems. There may be an information number for your local government that would tell you where to call, or you could start at your local library.
