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.

1. normal winter driving in northeastern Ohio. 2. anti lock brake system failed to operate. The result was immediate loss of control of the vehicle, causing it to slide into oncoming traffic on a rural country road where it was struck by an on coming car. 3. the car is totaled as assessed by the insurance company, no repairs made.

The vehicle was in service 3 times within 14 days, GM says the problem was the ignition switch, I say the source of the problem has not been fixed. Engine stalled 6 times in moving traffic, the "ABS" warning light is on, some time the "check engine soon" light comes on. Dealer replaces throttle body injection assembly. Next day the vehicle stalls again with same symptoms. Dealer replaced ignition switch again. !4 hours later engine stalls in moving traffic. Dealer installs event recording device, engine stalls and identified low ignition voltage (6.7 vs 13.6 vdc). Source of problem could not be identified, dealer says vehicle is safe to drive. We filed a lemon law claim.

When reaching a stop sign consumer applied pressure on the brakes, instead of vehicle coming to a stop, it accelerated and ran onto two curbs, finally crashing into a play ground.

Consumer stated the rotors and brakes were rusted. This resulted in extended stopping distance.

problem #2

Envoy 6-cyl

  • Automatic transmission
  • 7,000 miles
My wife was driving around 35 mph during a clear day when suddenly the steering wheel of our 2003 GMC Envoy started wobbling and she couldn't control it anymore. She stepped on the brakes but the vehicle wouldn't stop. The vehicle went over the curb and initially hit a utility pole on the left passenger side, then eventually hit the tree with the front bumper and knocked the two stationary objects down. Surprisingly, the airbag didn't even deploy. The insurance company declared the vehicle total wrecked and unrepairable. As expected, GMC declined responsibilities. They sent a so called independent investigator but they wouldn't give me his phone number. The report they sent contained only raw data about the airbag and nothing about the steering wheel. I will never buy or recommend a GMC again.
