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.

Since August of 2009, having problems with engine/transmission. Vehicle "died in flight" in August, vehicle coughs, stutters, and stalls out every day at first start-up, and I'm experiencing harsh shifting daily. I'm advised there is no resolution to the daily stall-out problem even though the vehicle has been in to the service department four times since 8/6/09. On last visit to service department I was advised that "GM is aware of the problem but has no fix for it" (case #11074714).
