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.

While driving at 25 mph consumer smelled something burning, like electrical wires. Stopped and pulled off road. Lifted hood and burning wires smelled stronger near alternator. Touched area, and it was hot. Took vehicle to independent repair shop, and was informed that alternator failed due to bearings burning out. Front bearings caused the alternator to burn. Had to replace old alternator with a new alternator that had larger/bigger bearings, and would not wear out as fast.

Traveling @65 mph engine just shut off. Would not start until 3 hours later then it was hard to start. Problem was determined to be ground under passenger seat. Car still was hard to start now the deal claims it is the fuel pump regulator. Very upset with this experience. Other problems seem to have cropped up due to this ground problem such as alternator failure, headlights failing to the on positon, power windows would not work and of course the failure of the fuel regulator. This ground seems to be a major problem and I am surprised there has not yet been a recall. The common thread can be seen in the complaints lodged on your internet site.
