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 Blazer Owner Comments

Got into the vehicle in the morning and when I placed it into reverse I heard a loud shattering noise and the car would not back up. I had it towed to the transmission shop and they reported that the "sun" gear had shattered with a repair cost of $2300. They also told me that this is a very common problem with GM transmissions due to a weak gear from the manufacturer. After researching it on line I am finding many other people with the same problem. The GM customer rep was very short and stated that the car was out of warranty and I have no claim. If this was a known ongoing problem GM could have recalled these vehicles and saved a lot of grief for their customers. I feel that I should be reimbursed some of the expense of this known defect.
