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.

Consumer 2004 Avalanche sometimes will not start and stalls while driving. ** answer required*** the dealer attempted to solve the problem but failed several times. The consumer's wife experienced this problem while traveling at high speeds, losing the power brakes and power steering. On another incident, the consumer's wife was turning into an intersection with a sufficient amount of time and the vehicle stalled again, nearly causing a serious accident.
