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.

Strap on gas tank broke (rusted through) while driving on bumpy road. Tank fell and hit driveshaft. I was surprised it didn't rupture the tank.

Avalanche 8-cyl

  • 200,000 miles
I was driving approximately 15 to 20 mph down a hill that was curvy and all of a sudden my truck completely shuts off as I was driving down the hill and almost went into a ditch because the truck just shut off while in drive and luckily I was quick enough to put it in neutral so I could steer it away from the ditch and I turned the ignition over and luckily it turned on while in neutral otherwise I would of crashed into the ditch. Then it shut off again about 30 seconds after and luckily I was able to put it in neutral again so I could steer and coast down the hill because it wouldn't start up the second time when it all shut off. I was stranded at the bottom of the hill near a light so I tried to start it again and it would keep trying to turn over but wouldn't start again. I was stranded in the middle of the road and had to call aaa to tow my Avalanche to my house. This could of killed me if I wasn't quick enough to figure out to put it in neutral to be able to steer. There should be a recall on whatever made this happen and I still don't know what is wrong with it because it happened late last night and I was looking for recalls and it doesn't show anything on this.

In the mornings I turn on the truck and it stalls, and the idle bounces up and down like it is going to turn off.
