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.

I have had the car since 3/05 brand new off the show room floor, currently have about 38K miles on the vehicle -since I have owned the vehicle more than 20 times while driving all of the lights will come on the dashboard and the seatbelt light will chime --then the battery light will remain on for approx 15 to 20 minutes-have had the vehicle on for service numerous times and they have replaced module after module -cannot diagnose problem. On at least 5 occasions while driving at highway speeds of 50mph or more the vehicle will just turn off and everything will lock up. Vehicle will restart right away but there is no warning that the vehicle is about to stall or turn off --had in for service numerous times -have been assured that the problem is fixed and then it will happen all over again. This vehicle is a hazard to be on the road -as Chevrolet truly has no idea what is causing the problem, they believed the problem was due to the remote start in the vehicle -they replaced that numerous times and finally removed all together and the problem still exists. There is no telling when the car will shut off it will be fine for days and the problem will resurface. Last incident date was 3/27/09 -problem started in 2007.

Speedometer doesn't work most of the time. It will freeze or go to 0 at any time or at any speed. This is a G.M. problem that has resulted in recalls on some SUV's but not any cars. If you were to google G.M speedometer problems you will get over 200,000 hits. Dealers know the problem exists but G.M is denying it is a safety problem. I have to assume when you are driving a car and don't know how fast you are going that is a safety issue. G.M customer service says there may be a recall someday if they get enough complaints...the car in question is a 2004 with 9500 miles. I feel this is something that needs to be researched. To recall some trucks and SUV's but not the cars is stupid. I would hope our gov't can help resolve this problem...after all G.M would like our tax dollars. Thank you
