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.

2004 Chevrolet Suburban Owner Comments

The coolant level in the reservoir continued to drop, prompting me to refill it weekly. Service shop worked on this on and off for several months. After several engine overheating situations, we took it to a different shop. Turns out our heads are cracked. They were manufactured by castech and are known to be defective according to GM bulletin #06-06-01-019B (document id 1986750). There is now so much anti-freeze in our engine that the entire motor needs to be replaced due to the corrosive nature of the fluid. GM said that they would pay nothing towards our repair. The engine only has 91K miles and now needs total replacement B/C of an issue that GM knew about since 6/12/07 but never contacted us about. Had the replaced the heads back in 2007, we most certainly wouldn't be facing total motor replacement at this time.

Owner of a 2004 Chevy Tahoe Z71 4X4 lat August 2006 my vehicle will not start after an overnight stay. Since purchasing the vehicle in may of 2004, I had to replace the speedometer. After towing my vehicle to the dealer, 5 times I was told that I had a bad intake manifold and it was causing my vehicle to not start. They replaced it. A few weeks later. About a month later my vehicle did not start. I took it back to the dealer, they claimed that they couldn't find anything wrong. 3 weeks later the problem emerged again, this time I was told that my battery was bad, they replaced it. Now this weekend of March 10, the same problem. My vehicle is dead and will not start. I am very anal about taking my vehicle for regular checkups. Why is that there is something wrong with the vehicle but the dealer cannot find or fix it. I cannot rely on Y vehicle, I may go to work or to store etc. Expect to get in my vehicle to come home or even on vacation. The point is that I don't know when it is going to start or halt on me.
