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.

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.

My 2006 Trailblazer gas gauge has failed. When filled the gauge will show full then gradually fall to empty. It now shows empty after fill-up. I now have to rely on mileage tracking on my mileage odometer trip gauge so not to run out of gas. I have been told the fuel sensor(s) have failed and that a investigation to recall is in effect.

My 2006 Chevy Trailblazer ran out of gas on a rural road leaving me stranded. The gauge does not register properly. It floats around. I cannot afford the $600 to replace the system at the dealership. I understand that this is a common failure for this model vehicle and think that it should be covered by a recall..

The fuel gauge worked great and eventually started to read empty when there was plenty of fuel in the tank. Sometimes it starts at full and slowly goes to empty. Other times, it goes straight to empty without missing a beat. Now it occurs all the time. Have yet to repair it because I see that supposedly a recall is in the works and there should be!! with as many people that have had the problem including accidents and other extreme inconveniences, GM should definitely do something about it.

Chevy Trailblazer - gas gauge inaccurate that caused vehicle to stall on the highway. It said I had more gas than I actually had. Also, the gas gauge was overall not accurate. It was one level and then a few minutes it was much different. I eventually had to have the sensor replaced at the Chevy dealership.

Fuel gauge began reading inaccurately for a while. At one time, the gauge showed a quarter tank, but then my vehicle shut down while I was driving on redwood hwy in grants pass, or due to being out of gas. Since then, the gauge has completely stopped working. Sometimes, the gauge will show up to a half tank, but the needle quickly falls back to empty. This is a chronic problem. Two mechanics have told me that the sending unit very commonly fails on Trailblazers and that he would need to drop the tank to replace it.

When I filled my car up it would suddenly show it was empty & a check engine icon showed up & yellow low on gas warning light started dinging last fall 2010. When I drove approx 25 to 30 miles it would register gas normally & engine light would go away. I fill up every 2- 3 weeks normally. Then this past February it went haywire & when I fill up it goes to the empty side, engine icon shows up & low on gas light dings & it never registers correctly at all, the gas hand is all over and I have been having to use the mileage gauge to even know how much I might have. It low gas warning will star dinging & I am driving down the road or interstate for no reason & startle me. It has caused me to suddenly jerk the steering wheel because I am startled & that is dangerous in itself. Our family has been owned GM cars from the mid 1990's on and this has caused a very unsafe feeling for me. I have children & grandchildren with me and I feel very unsafe for the 1st time in this vehicle I am so nervous just driving to work & back & my eyes are constantly monitoring the panel when I need to keep focused on my drive. I am so concerned that since the gas gages are so wrong what would just keep it from "sensing" there is no gas and suddenly stop! I would hate for it to take a death to push this problem to be a recall. I am also a consumers report panelist and this will be on their report this year for sure. I have dealt with the noise issues as you drive & small things that happen as time goes on, but this is definitely an issue for recall. I need a safe vehicle and to trade is not the answer yet as I would not be honest in something else buying this car and maybe losing their life please I beg listen to the notices you have received concerning this, these are real as I have sensed myself in their concerns & complaints.

2006 Chevrolet Trailblazer, 4dr, lt, 4WD. Fuel gauge stopped working. Fill up tank, gauge goes up to full, but then falls back down to empty. I do not know the level of fuel in my vehicle. Appears to be a common problem among 2003-2006 Trailblazers. Have ran out of fuel on the road. Most likely fuel sensor or cluster.

Trailblazer

  • 61,331 miles
The fuel gauge recently stopped working after filling the tank with gas. It reads empty (and the low fuel amber light illuminates and the warning bell chimes). It then will go between 1/4 tank to empty to full to empty (back and forth) even though the tank is completely full. This vehicle suffered the same problem when it was under warranty (it had less than 3 years 36,000 miles). At that time GM replaced the "fuel sensor sending unit" at no charge to me since the vehicle was under warranty. We are not suffering the same problem. I would have to surmise that there must be a defect since it can not possibly be normal to replace a fuel gauge sensor twice on a vehicle that is just now five years old with 61,000 miles on it. I fear for my family's safety since an accident could result should our Trailblazer run out of gas...stall...and subsequently cause an accident.
