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.

  • 37,000 miles
As I was leaving las vegas on I 15, I got a message of reduced power. I was just out of heavy traffic, traveling about 70 mph, when the engine slowed to about 1,000 RPM with out warning. Found out later that it was a broken lead wire to the throttle position sensor. The truck had about 37,000 miles onit. The truck is a 2007 2500hd with 6.0 engine. The trucki has never been worked on, and is line new. Dealer installed P/N 88986255 connector. I received half or the cost back after calling GMC. I feel that this is a safety problem. As I was just out of heavy traffic and could pull off of the road.
