Huge win for car owners! All TSBs to be made public. The Center for Auto Safety just made the NHTSA (US Government) make public the full text of all TSBs from now on. They are the same organization that has petitioned the NHTSA & filed lawsuits to protect car owners over exploding gas tanks & other major safety issues. Whenever you drive in your car, you are safer thanks in part to a lot of work over the years by this small but very effective consumer advocacy group.

Please take a moment & say thank you by donating $5 or whatever you can to the Center for Auto Safety.

Envoy XL 6-cyl

  • 94,525 miles


Driver had just exited a parking lot onto a main road in the evening. The car was cold, had not been used since the morning. The car failed to take power after slowing down for a light that was red than changed to green. The car was on and in drive, but failed to go further. There was no warning whatsoever. The driver braked and stopped, nearly causing the car behind to rear end the GMC. GMC driver had put flashers on immediately. The car was put in park, turned off, than restarted. The GMC was put into drive, but again would only roll. The driver put the car into gear 3 on the auto trans, than 2. in gear 2, the car moved. The GMC was immediately moved back to its parking spot. A diagnostic shows the transmission has failed. Only 94,500 miles, and the GM transmission is dead. In looking on line at certain consumer data and speaking to local mechanics, all point to transmission failures on the GM SUV products, including Chevrolet trailblazer & GMC Envoy.

Envoy XL 4WD 6-cyl

  • 40,644 miles
I own a 2006 GMC Envoy XL. Last may of 2009 I was driving on us state 30 with my children when the driver's side door start smoking vigorously without warning. Just as this happened the vehicle shut down in the middle of the highway while I was driving. I was able to restart the vehicle after a few attempts and remove it from traffic. I then tried to open the drivers door to get out (the handle its self was not smoking) and it would not open. I climbed into the passenger's side and manually opened the door, got out, then removed my children also. This incident was reported to GMC and their answer was that the car shutting off was designed as a safety feature. Explain how this could be safe in my situation? the consumer stated the 4-wheel drive recently failed for the fourth time in disastrous weather conditions. On February 17, 2014, the 4-wheel drive was not operating properly in a serious time of need. On February 19, 2014, after 6 1/2 hours, the problem was finally diagnosed as being the decoder motor and wiring for the fourth time since February 15, 2010. Updated 06/05/14.
