Seven problems related to wiring have been reported for the 2002 GMC Envoy. The most recently reported issues are listed below.
As I was driving down interstate at 70-75mph , the headlights, dash lights, all the lighting just shut off! I had no idea what to do. I was on one of the most dangerous interstates, known for fatal accidents. . . And I'm driving in the dark without lights! I quickly moved to side of road and shut it off in case of faulty wiring/fire hazard. After approx. A five minute phone call, I started car, lights worked. Started driving again, approx. 10 minutes down road, lights shut off again. I hope this problem is resolved soon! this is dangerous and can kill people!.
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.
Stoped by cop, unaware rt front light went out, got warning letter. Socket burnt and smelled strongly of electrical burning. Taking it to dealer on Monday.
The contact owns a 2002 GMC Envoy xl. The contact stated that he has been experiencing the same failures as noted in recall # 03v096000 (electrical system: wiring: interior/under dash). He has taken the vehicle to the dealer, but the failure still persists. The contact stated that the seat belts continue to lock and the windshield wipers are malfunctioning. The wipers have been replaced numerous times and the failure causes limited visibility in certain weather conditions. The suspension for the arms of the ball joints was replaced and the vehicle continues to shake, shimmer, and make a loud noise. The vehicle was repaired, but the failures are ongoing. When turning, the steering wheel hesitates and causes the vehicle to jerk uncontrollably. When the windows are down, the interior lights dim due to an electrical short. The tires were changed four times, but continued to fail. The contact stated that the brakes have been replaced repeatedly. The dealer stated that the discs were failing due to adverse weather conditions. The current mileage is 68,000 and failure mileage was 38,000. Updated 1/15/09 the catalytic converter, the camshaft, and engine coil was replaced. The check engine light is still on. Updated 01/21/09.
Transmission does not work properly. Have had it repaired twice, but still vibrates, and fails to move vehicle forward at times, from a dead stop. Is very dangerous at intersections where moving quickly is imperative. Also wiring problems which operate various remote instruments (mirrors, seats, etc. ) fear of fire. Rear door latch was replaced - clicks "locked/unlocked" while driving. Seats move on their own while driving.
My 2002 GMC Envoy lost all power three times at high rates of speed. The first time we had it serviced and I was told a module needed replaced. The second time, the car shut down at highway speeds but restarted approximately 15 minutes later but then the same thing happened again the next day while my wife was driving home from work traveling at 65 mph down a highway. We had it serviced again and this time I was told it was due to a loose wiring harnass. Car has had numerous problems since and it is an unsafe vehicle for my family to be transported in.
The electrical computer memory for the exterior mirrors and the seat adjuster failed. This caused the seats for driver and passenger side not to be adjusted. Also the mirrors are not able to be adjusted. Driver has to continously adjust the miirrors in order to see. Dealer reset memory seats, reprogrammed mirror memory, and replaced left and right front seat modules. Did not remedy problem. Customer states that there is a fuel leak loss of 1/2 tank in 3 miles. Dealer repaired loose connection between main fuel line and the fuel tank.
