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 fuel gauge quit registering how much fuel I have in my tank, and as a result I have to stop and fill my tank more often than needed so that I dont run out of gas (which has happened). I also received a letter from the mfg that they are aware of the issue, however because it is not safety concern they would only cover 50% of the cost to fix the issue. Last time I checked running out of fuel is a saftey issue, not just to the person driving the vehicle but to others that may be driving behind said vehicle that runs out of fuel. I have not fixed this issue as I dont feel like I should have too, I feel that GM should pay to have these issues fixed.

After filling the fuel tank to full, the fuel gauge read empty and the display read "low fuel'. after driving a few miles, the gauge read different readings from 1/4 tank to 3/4 tank and would sometime read full and slowly drop to empty.

I purchased a used car from ez cars & credit located in riverside California because they had some very good reviews. I could of bought a car from a private owner but I decided to go with a dealership because I figured that the law would protect me and they could not sale me a defective vehicle. I purchased an SUV, Chevrolet Trailblazer 2006 on 2/07/2013 and after taking the car for a test drive, I noticed the airbag light on. The manager [xxx] said it was just something that could be fixed in like 5 minutes and that it had to do with the fuses being replaced but his service technician left for the day so I should bring the car in tomorrow. I contacted the dealership and asked for [xxx], I was told by the sales manager who's name is [xxx], that [xxx] was on vacation for 1 week in Mexico. I explained the airbag situation and[xxx]said he doesn't know anything about it and I would have to wait for [xxx] to return from Mexico. A week and a half later driving with the airbag light on, not knowing if my kids, husband or myself were safe in this vehicle but we spent all our money to purchase this car. We here from [xxx] so I brought the car into the dealership, [xxx] had the car for 4 days and the airbag light is still on today! I contacted [xxx] and told him I was on my way to pickup my car, mr. [xxx] he was at the office, now when I pick up my car, I get my keys from the owner of the auto repair shop next door. He doesn't even work for the dealership! I have serious water corrosion under my car, the steering wheel feels shaky the fuel gauge never reads correctly and the lights go off and on inside the car after a while of driving. I don't know what to do?? information redacted pursuant to the Freedom Of Information Act (FOIA), 5 U.S.C. 552(B)(6).

My Trailblazer is also having problems with the gas gauge. My husband actually ran out of gas and had to walk to the station buy a gas can and walk back to fill it. We can no longer reset the trip miles as this is the only way to tell accurately how much farther you can drive on a tank of gas. I have a 2006 Chevy Trailblazer.

After refueling the gas gauge still read empty, bounced up and down, gas gauge light came on, service engine soon light came on, pulled over, turned off car, turned on car- same thing - has happened with every refueling since. Only way to know how much gas is in car is to watch and reset tripometer- which does not always happen with various family members- making it unsafe for long distance high speed highway travel since you cannot rely on the gas gauge, or even know if service engine soon light actually means something other than gas gauge.

After filling up my tank, as I pulled away from the pumps, the gauge registered empty, low fuel light came on, and check engine symbol came on. I pulled into parking lot; the engine sputtered and refused to start for a few minutes. After a day or two, the gas gauge showed full, but it fluctuates between full and 1/2 all of the time. This happens every time I fill up my tank! I am afraid to go out of town because of the low fuel light coming on. I now have to rely on my trip meter being on display constantly so I can estimate how much gas I have left. I have seen hundreds of complaints regarding the same thing happening in Trailblazers, but I have not yet received a recall notice from GM. Shame on you, GM! and you wonder why we're trading your product for foreign autos!

Initially the fuel gauge began fluctuating and working intermittently. Then, it stopped working all together. It always says the vehicle is on empty with the gas light and the check engine light staying on 90% of the time. This is very frustrating because if there were a problem with the engine, I would have no way of knowing whether the light is on due to the fuel sensor or because of another more serious issue. I also must rely on the "trip meter" to determine my fuel level. I have found this is a very common problem with these vehicles and would hope Chevy would take responsibility.

On November 16,2012 I stopped to get gas. After getting gas my low fuel light was on and the fuel gauge registered as if the vehicle was out of gas. Having known better I started the vehicle which hesitated to start. It finally started but sputtered its way out of the gas station. As I finally cleared the gas station the vehicle stalled and came to a complete stop without any warning and I was hit from behind.

The truck has been at a several times into a chevorlet dealer, the check engine light the reduced engine light and the traction control lights all come on at the same time and it causes a failure in which the vehicle losses 90% of power. The failure happens at random time and all weather and traffic conditions. I have had it at two dealers as well have contacted GM executive dept. They have claimed to be fixed several times but it still fails. The issue at hand is that in traffic conditions this failure proves to be a huge safety hazard for myself and other drivers on the road. Its not a used car issue as its an electrical failure issue. I have asked time and time again to have a GM field tech come look at the car but, they insist that the dealer fix it. I need someone more to see and understand the failure comes with at great risks of other drivers on the road. If you goggle this problem you will see others have the issue and I think its worth a recall if they can find a fix for it but after 3 years and several tries they are still unable to fix the issue.

My fuel gauge on my 2006 Chevy Trailblazer just stopped working. One day was good with half a tank and the next day I went to turn it on, the fuel gauge read empty. Now the fuel gauge at times tells me I have full tank then empty then half a tank etc.

Fuel system sending unit appears to have failed. Fuel gauge swings erratically, and has no relation to the actual fuel level in the tank. Check engine light came on due to signal from faulty fuel sending unit. As a result, vehicle ran out of fuel on the highway during rush-hour. Upon investigation, it appears that there has been a previous investigation by the NHTSA that has been closed. Chevrolet has agreed to pay for 1/2 of the cost of repair. Unacceptable. I request that you reopen your investigation, and make Chevrolet take responsibility for this issue. This is a definite safety issue, as running out of fuel on a busy highway can be a potentially life-threatening event. I never received any notification that this was an issue, although some owners are claiming to have received a letter from GM.

Trailblazer

  • 55,000 miles
Don't have the exact dates and miles but I have had 2 instances where my gas gauge stopped working after filling up. First time I had the issue fixed at the Chevy dealership while under warranty, then maybe a year later it broke again. I have not gone to fix it. Due to the gauge never showing gas in the vehicle my check engine light comes on. I drive about 200 miles until I go and fill which would be around 1/2 a tank. I cannot go on long trips as I would never know where I am on gas. One time breaking I can see since this appears to be a well known issue with the vehicle, but a 2nd time after the dealership replaced it seems like really faulty parts or dealership errors. I have been quoted between $300-$500 to fix the problem but not by a Chevy dealership. I have many issues where I purchased this Trailblazer. I don't know if Chevy would fix this again at their cost and I would hope this becomes a recall after nearly 1,000,000 complaints.

I start the car and the gas gauge shows that I have a full tank of gas, as I start driving the gauge will suddenly go to the empty line and start dinging that I have no fuel. Once it showed that I had a half a tank of gas, but then I suddenly ran out. I was stuck on the side of the road with my two children until help arrived. This gauge problem has happened daily since day one. I am now relying on my trip meter to know how much gas I have. I like this vehicle but if this continues with no help from Chevy/ GM I will be forced to trade this car in!

Immediately after filling up, my 2006 tbss fuel gauge stopped working. I fill up with non-ethanol gas premium grade. The low fuel message appears on the dash along with the needle sitting on empty and the low fuel light remains on. I have read over 250 complaints of the same problem.

Gas gauge showing more fuel than in tank....I ran out of gas....car shut off in traffic. Gas gauge would float from full to empty and stop along the way, so you did not know how much fuel you had. Then it just stopped working all together.
