My ignition coil (?) became stuck/frozen and would not turn - thus the car would not start. $700 later, I got a new ignition, but now my lighter doesn't work, half the lights on the dash no longer work, equipment was not bolted down under the hood and for the cost of this repair, at least the workmanship could have been a little better. This same problem has been reported on many chevy products that I have found on line and still no recall . . . I guess it will take a few people dying before this turns into anything like that.
