2005 GMC Envoy: brake failure

Filed Apr 1, 2022 · Brakes, Electrical · MI

All the gages have stopped working correctly. They do not report proper information to driver . The electrical wiring to the rear wiper, license plate lights and rear hatch stopped working. The most dangerous thing is the ABS brake system dash lights and bell comes on every time the car is driven and the brake pedal goes to the floor when trying to stop.

I just want to add to my recent complaint made December 2021 file number 11444000 when our left side brake failed to disengage completely causing the vehicle to vear left into 2 traffic light poles. recently have the front end rebuilt and noticed the seat belts needs to be replaced or rebuilt but the passenger side belt is retracted so hard I cant get it off the seat, it is crushing the seat basically and I see other complaints of this happening and almost suffocating the passenger. I was lucky my wife was not with or the belt would have pinned her in, the driver belt is stuck as it was when i removed it.

Takata recall, early morning, my power steering stopped working, so I filled it and it started working again, as I was driving down a busy road turning onto my own street, the power steering and brakes failed resulting in me crashing into a pole, and the air bags did not deploy and the seatbelt did not lock, so I flew into the steering wheel, breaking my hand. The damage was so severe it was considered totaled.

There was ignition switch failure while driving the vehicle. The power steering and brakes gave out, the engine shut off, and all the lights on the dash came on. It resembled the car running out of gas without doing so. After I pulled off the road with great difficulties, I put the car in park and the vehicle got stuck in it. The engine would not turn over after this occurred and needed to be towed. There is no release switch which the tow truck driver said there should be so he could get it onto the truck, so the vehicle has to be drug with the wheels locked onto the flatbed and then pushed off in the same manner. We paid to have it fixed and it has now happened again 5 months later. There are many reports of this online and it is not just with the gmc envoy denali it also includes the chevy trailblazer and possibly other vehicles manufactured by gm. There was one person online that said they keep spare ignition switches in the vehicle and the tools to swap it out because of how frequently it happens. The dealership replaced the part and it is not available as far as I know, because it was not returned to me. The vehicle was a 2005 gmc envoy denali.

2005 gmc envoy denali w/37,800 miles. On several occasions, while completely stopped, the vehicle would slightly lunge forward as if going to accelerate although the brake was engaged. When local gmc service dept. Was called by owner to inquire about problem, service tech said he had no reports of such situation. The surge happened again on 10/31/08 and there was a passenger in the vehicle who also experienced the sensation. On 11/17/08 while at a complete stop, after turning wheels sharply to the right to go around a road equipment vehicle in the parking lot, upon removing foot from brake, the denali lunged forward enough to bump the tire of the equipment vehicle and then it accelerated as if the cruise control was activated. There were no brakes when an effort was made to stop the vehicle. Steering of vehicle was hard due to power steering failure . Vehicle jumped upon a curb, driver forcefully turned steering wheel to avoid hitting a brick building as acceleration was still ongoing. Vehicle crashed through a steel garage door and continued until it crashed into a retaining column at which time the motor was turned off. The impact of the collision could be felt up to the second floor of the building. The driver was wearing a seat belt. The onstar services did not initiate response to driver despite the fact that the front bumper of the vehicle was no longer attached to the vehicle, nor did the driver airbag deploy upon impact. Vehicle was towed away from the scene. Driver was transported to hospital by ems for injury evaluation. Several witnesses described incident as "vehicle out of control". *tr updated 10/29/10

In august 2005 on a trip, exiting off ramp brake pedal went all the way to the floor, was able to "pump" it and get response. After shutting vehicle off, setting & restart brake pedal again goes all the way to floor. Upon return to dealership master cylinder was replaced. A few months later brake pedal becomes extremely "spongy" with no stopping power. Dealership bled brakes and said problem was air in system. Still no improvement, extremely soft pedal and unit will not panic stop. Took back to dealership end of june 2006 and they replaced master cylinder a second time. Unit is still no better and in my opinion unsafe to drive if it will not panic stop. Dealership says gm has told them to order more parts, but do not know what the problem is.

I was driving home from work entering the freeway on ramp. The ramp is controlled by a signal and I was waiting my turn when the engine failed. I was coasting downhill into another car when I hit the brakes and there were no brakes. I bumped the car in front of me damaging the front grill and hood of my car. Submitted the car to the dealer for evaluation of an electrical problem. The dealer has been unable to duplicate.
