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.

Vehicle was purchased 1 year ago and continues to stall. It stalls at high speeds. Has taken it to the dealer, he says it is a fuel pump issue, they have replaced the fuel pump, and the problem is still there. Chevrolet says this effects vehicles above 5000 feet. And on hot days. Consumer lives at 6000 feet and vehicle does stall at high speeds.
