GM took my car in and replaced the ignition switch and keys. All the problems I have now with the electronics, were not there before the replacement switch. Now my speakers don't work and warning lights come on for a couple of days show everything from flat tire to engine trouble. I have it checked every time it happens and nothing is ever found except being told, it's an electrical problem and that should be covered under the manufactures warranty, since it all worked before GM put it in the shop. The Dealership wants to charge me for repairs, time and labor. Even though it's the same place my car was taken for the ignition problem. This car is a lemon and needs to be repaired by GM or Replaced by GM..
