Continued electrical problems with 2002 GMC Envoy. Such as on-star telephone along with radio/cd player, all four doors failing to lock or open including the back hatch. Service air bag light and engine check lights coming on. Reprogram engine/transmission module, also telephone antenna replaced, short in wiring located due to rubbing/pinching during construction, replaced wiring harness. Hundreds of dollars required to identify short in wiring. Transmission operates sluggish until warmed-up vehicle feels as if the brakes are on until it has moved several blocks.
While driving at 65 mph engine shuts off; would not restart first try. Would start a little later. Went to dealer, reprogrammed PCM with latest calibration update. Second time happened at 70 mph.
Consumer states while comiing down a hill PCM shorted out. As a result, driver lost all electrical functions. Steering wheel got really stiff. Brake pedal became hard to press.
