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.

Avalanche 8-cyl

Reduced engine power, engine dies no power steering or power brakes almost rear ended on I-25. Trouble code says P2135 throttle body has happened 20 times or more in 8 months. Dealer where purchased say they never heard of this problem then said new wiring harness might fix it, knew the price without looking it up? there are thousands of posts on line about problem, but they never heard of it.wiring harness replaced throttle body cleaned and checked peddle checked still happens, have spent hundreds. No solution. I have to drive on highway to get to work on oil rig, I'm afraid it well cause an accident.GM doesn't know what is causing problem and doesn't seem to care.
