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.

Fuel gauge for the Trailblazer would bounce back and forth to empty and the full. This went on for a couple weeks but now only stays on empty.

Bought used, mileage indicated above. The fuel gauge was showing an approximate proper amount at 1/4 tank. On first fuel up, full, the fuel gauge went to show "empty". it stayed like this for an approx. 1/4 tank, then went to the actual fuel amount. This occurred for about the next 5 fill ups, then the fuel gauge would not work at all....always showing empty. This has caused me running out of fuel twice, luckily I was able to stop vehicle safely, both times I was in moderate to heavy traffic. I have found no recalls, but many complaints! what's up with this! I have lost trust in Chevy for not fixing an obvious factory problem!

I stopped to fill my car with gas as I was on a little less than a quarter of a tank. The fuel light had not come on, nor the check engine light. After filling the tank up all the way with fuel, I got in the car and the fuel light came on, and the needle wouldn't leave empty. It stayed this way for about a mile till I got home. I shut my car off in the driveway and waited a few minutes thinking that it must play "catch up, " but when I turned it back on, it went to full immediately, but then immediately went to empty with the fuel light on. As soon as this happened, the check engine light came on as well, and goes on and off, which I suspect has something to do with the sensor in the fuel tank. I googled this problem and found that there are several sites, with a lot of people experiencing the same exact problems. I am now having to set my trip meter so that I don't run out of gas till I get it fixed. Hoping someone looks into this.

Wife filled Trailblazer with fuel during a trip today. When she returned to vehicle and started it low gas light on gauge cluster lit and fuel gauge went to zero. Vehicle was purchased at 11,000 miles and gas level has never been allowed to fall below 1/4 of a tank so as to prevent fuel pump overheating and failure, hence, this was the first time the light has been on.

Fuel gauge stopped working. At first it dropped to empty, and stayed there for about 15 miles. After driving for about 15 miles the gauge would slowly return to the correct fuel level. Over time, the problem worsened, as it started taking longer and longer for the gauge to recover to the correct level. Now it stays on empty nearly permanently, only occasionally registering some fuel at startup and quickly dropping to empty again.

Fill the car up and the gauge still show empty and the light was on, when I pulled in to the gas station the low fuel light wasn't on and I had a 8th of a tank but when I filled it up it didn't register and the light was on I drove around for couple of days and put $40 in and the light was on and gauge show empty. To me this is a safety issue if I ran out of gas and someone runs into me I should not pay 50% Chevy should pay for it to replace it.

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.

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!
