On 7/26/2003, the owner heard the motor running while the vehicle was off. The owner disconnected the battery to stop the motor from running. This caused the owner to manually lock the doors but the hatch would not lock manually. On 7/31/2003, the vehicle was taken to the dealer who found a short in a wire under the hood and corrected the problem. Please provide details. *ph consumer stated there is no way to open the rear hatch if there is an electrical failure. There is no mechanical device to lock or unlock the hatch door. This could be a significant safety hazard. *ph
Vehicle's dash gauges came on and speedometer started fluctuating after 35 miles driving and vehicle stalled out, not being able to restart. Computer was replaced by dealer. Problem arose again about a week later. Gm had dealer replace another part in I believe the ignition key area. Check engine light came on again in a couple weeks and vehicle would not start for dealer after it was driven there. Dealer found wire connection in wiring harness to computer was not making continuous contact at a connection. Also dealer had to replace a switch when the A/C would work intermittently. Luckily I have a good efficient dealer and service department who cares about their customers.
