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. Notes: Carrying the not-so-proud traditions of its 2002 predecessor, the 2003 has a handful of instrument panel malfunctions that can leave you guessing your speed, engine temperature or how much gas is left in the tank.

A D V E R T I S E M E N T S have you seen this? these fools should never have been performing tests like this in public highways. Tests like this, should be done on closed courses. They did this for show and to get attention and could have been deadly. They should be locked up.

The contact owns a 2003 Chevrolet Trailblazer. When the brake pedal was depressed, the ABS and security warning indicators illuminated. In addition, all the gauges on the instrument panel failed. The contact stated that the terminal battery needed to be disconnected and reconnected in order for the instrument panel to function properly. The failure occurred on several occasions. The vehicle was not diagnosed or repaired. The manufacturer was not notified of the failure. The approximate failure mileage was 115,000.

Car is a 2003 Chevy Trailblazer the ignition key is still stuck in the car. There where no warning lights that anything was wrong with the car. Brakes failed after 7 months of having the car, I had to go to an outside company to fix car. Also when hitting brake lights it comes on as hazard lights. Car started to shake when turning on A/C took to dealership I was told to contact someone else that can fix the car. Also the only way for me to start the car and turn the car off is by unhooking the battery due to key being stuck in the ignition I went to dealership to get car fixed or replace and dealership was bankrupt. Please help I really feel that I got a bad car or a recall car.

This is a third time the ABS warning light has come on malfunctioning saying we need service once in Montana and then another incident in 2008. "service brakes, air antilock ABS warning lights come on in the drivers information center. However, it happens every time it gets 5 to 10 degrees or more below zero. The first time I took it into garage and they cleaned up the ABS ground connection on the frame. This is a safety issue because a person doesn't know if it is accurate or another false alert. I would hope that other persons report these issues, and that the manufacturers would be forced to repair the issue.
