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: 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.

Trailblazer 4WD 6-cyl

I bought this SUV to go off road, mostly riding in the sand on the beach. The first time on the sand it did not want to go and I thought my husband or I did something wrong. However the second time it went a short distance and then sank up to the axles and we had to have it towed off the beach. It was taken to the dealership and they could find nothing wrong with it, and acted like this was the first complaint on this problem, however my accountant has the same SUV same year model and same problem, took it to the same dealership and was also told there was nothing wrong with his Trailblazer.

All of a sudden the transmission started to shift funny after a long road trip. It did this once on the highway. We got off the highway and pulled into our town and the car was having problems shifting. We barely made it to our house and the transmission was leaking. We went to drive it to the dealership and it over heated less than a mile from the house. We were told that the radiator deteriorated and sent anti-freeze into the transmission which destroyed the transmission.

I parked a 2005 Chevy Trailblazer rented from budget rent a car in the hotel parking lot where myself and my fiance were checking in to. I removed the key from the ignition and went inside. Approximately 30 sec later the car rolled down the hill in a large arc (due to the steering wheel being locked) and collided with another vehicle. The car was in neutral. At that point I put the key back into the ignition and found that the key could be removed while in neutral, which caused the car to roll. The police arrived and also were able to remove the key while it was in neutral. This is included in the police report. I was not cited since the police officer found the car to be defective. Budget rent a car replaced the vehicle without question, however are now seeking me to pay for the damage, which is obviously being contested.
