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.

CarComplaints.com Notes: The 2002-2007 Chevrolet Trailblazer is known for many things, but perhaps it is most famous for its faulty fuel gauge.

This gauge flip-flops more than a politician during election season. Some report that the gauge says "empty" after a fill-up, while others report the gauge says "full" when they're running on fumes. Either way, there's one thing everyone seems to agree on: the darn thing is just wrong.

Following hundreds of complaints and a few accidents allegedly caused by the malfunction, the National Highway Traffic Safety Administration (NHTSA) opened an investigation into the issue in May 2011. Unfortunately for frustrated owners, no recall has been announced.

The contact owns a 2006 Chevrolet Trailblazer. While driving approximately 45 mph, the battery indicator illuminated on the instrument panel. Ten seconds later, the brakes failed and the brake pedal extended to the floor. The contact had to apply the emergency brake in order to stop the vehicle. She drove to a nearby dealer and was informed that the alternator failed while driving and did not produce enough energy to the brakes in order to stop. The dealer replaced the alternator and the battery. The contact believes that this is a safety hazard and the manufacturer should issue a recall. Through online research, he found numerous complaints for this same defect. The current and failure mileages were 33,900.

The contact owns a 2006 Chevrolet Trailblazer. The contact stated that the alternator failed to work properly. As a result, the vehicle made loud noises. The noise occurred every time the vehicle was started for at least four months. The contact has not taken the vehicle to be inspected for the alternator failure. He was informed by another dealer that the bearings were faulty. He feels that this is a saftey issue because the alternator and battery are needed for the vehicle to operate properly. The current and failure mileages were 39,000. Updated 02-18-09 updated 02/18/09.

Car started making a very faint whining sound and has gotten quite loud and have had it looked at and spoke to other owners with the same problem and so far have found out that the rear bearing goes out in the alternator quite early as in my vehicle which only has 28,000 miles on it.

2006 Chevy trailbazer has a bad alternator. I took the day off work to fix the vehicle. To my surprise you can't get one for this vehicle from anywhere. They are on backorder through GM. I guess I need to find a new way to work until my new one arrives.
