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.

  • 80,000 miles


I am filing a complaint.and will continue to file complaints until all of the consumers issues have been addressed. I understand that GM is not willing to hold theirselfs liable for these issues, but people spend pretty pennies out of pocket to purchase vehicles from these manufacturers to spend more money to pay for repairs after just a short while of owning these. I have researched issues I am having with my vehicle, and I am having all the above listed issues, and do not wish to spend large amounts of money to pay for these cost considering I am still paying for this vehicle. I just spoke with a representive about these complaints, and have set up an appoinment to pay a dealership for diagnostics, but am hoping that I can get closure on these issues without paying big expenses. I hope everyone else will follow suit and keep inputting your complaints until they are resolved. My vehicle issues are the fan clutch needs replaced, my gas tank has been replaced already, just replaced my serpintine belt this morning, my exterior lights (brake/turn signal) have been replaced 3 times over two months, and engine light keeps coming on, something doesnt seem right underneath this vehicle either. I just feel like I am paying for a peice of junk on top of paying to keep the vehicle running. Oh yea this vehicle has had to have thousands of dollars of body work done as well thanks to mother nature. I just hope they will be responsible enough to take on this responsibilty of theirs, not ours.
