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.

Ive had to continueously replace the brakes axles, warped rotors. As well as needing to purchase tires for front end due to control arms malfunction. Constant replacemenf of front axle all causing rubbing, mis alignment and front end sitting inward. These replacements happen more than 3 times a year the last 3 years of ownership.

I have had my SUV since 2011 have had no problems with it until about Feb. 25,2019. I had my brakes replaced ftont and back along with the rotors. A week after that I was driving on the highway come up to a red light was slowing down and when I got to 10 mph it started to paulsate and wasn't for sure if I was going to stop completely. I finally did. I took it back to my mechanic he checked the ABS to see if the wheels were spinning at the same speed and they were. When I go down my driveway whick is a hill I'm not for sure if it's going to fully stop or go on out in the road, we are on a blind curve and it's rather scaring. Also I have a problem with the stablility and track light coming on and staying on, I just restart my SUV again for it to go off. It's both of the lights on the track and stablitity. My driver side seat belt is frilly on one side and getting thinner.

Right brake light continues to go out and the connector is burned and corroded. Also, I am continuously replacing my headlights and brake lights. Once replacing, the light works for about 3-4 weeks. It appears there is a problem with the brake light connector circuit board. Please help!

ABS always engaging at low speeds, issue cause by ABS module located under vechicle, gets wet or moisture, poor GM design, poor location to pit electronics under vechicle. Alota of people online have same issue spening over $1000 on new module does not correct problem per online forums.

The manufacturer was not made aware of the failure. The failure mileage was 136,000.

All of the lines on my vehicle (fuel, brake, power steering) have really bad rust corrosion. These will have to be replaced before there is a serious failure. The truck is only a 2007 and the lines look like it's a 1987.

While driving at 45 mph (foot not on the gas, going downhill) the vehicle lost all power. Was approaching a stoplight and brake to stop. After truck came to full stop due to me braking for light anyhow, brake pedal became hard, unable to push down or pump. Stopped at traffic light not knowing what happened since gas tank was full, I shut key (truck) off, and on waited till light turned green, it restarted on the first attempt thank goodness. Why the complete powerfailure while driving at 45 mph, I have heard this could be onstar related, even though I am not signed up as a customer, if a Trailblazer 07 is stolen or in an accident, I heard the onstar features confusion w/ satellite and causes them all to shut down. Don't know if this is true, but something went way wrong, luckily no one was hurt or I'd be suing bigtime. Today is 10-12-12, yesterday got a recall notice in the mail for door/windows/locks problem. They will fix for free however no parts to replace are currently available, really"?" wow.
