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.

23sep10 1715 pdt my wife was driving to work on a highway when low fuel light went on. She had literally just filled the vehicle with gasoline. I had her exit off highway to sidestreet and call for a tow. I told her not to continue driving because it could be the fuel pump. I then looked online to find any reports of this. I found it to be the second most reported problem with the vehicle. We had just purchased this vehicle used a few days before. So we have no history with the vehicle. This occurred once. I did notice the light on once the morning of the same day. I plan to have it towed to and repaired at a trusted local mechanic. Online the estimated cost for repair is $550.

Fuel system, gasoline, in-tank gauge defective un-reliable, intermittent or random readings shown on gas gauge and yellow low fuel warning light not indicating actual fuel tank level. Resulted in a serious un-safe condition abruptly running out of gas on the free-way needing to pull off roadway with no power and limited control. With increasing numbers of customer complaints for the same issue GM is aware of the defective design, product reliability insufficiency, that is contributing to exposing operator, and / or passengers to hazardous unsafe conditions which may result in serious injury or death.

Fuel sensor on 2005 Chevy Trailblazer going out for the past year. If vehicle was filled, it would go down to empty after several minutes then over the course of about 20 minutes go to the correct spot. Recently it just doesn't give you any clue as to the amount of fuel in the tank. There are pages and pages of people with the same complaints online, so it's not just my vehicle. This is a major safety issue if there are lots of 2005 Chevy Trailblazers on the road without knowledge of how much fuel is in their cars. Please look into this, because Chevy sure isn't!

The gas gauge light comes on even though we have filled up the car. This happens now on a regular basis. The light will start making a noise when it detects there is no gas, but we just filled up the car. It is going to cost 1,000 dollars at the dealership and have noticed a lot of other people have this same problem.

The gas gauge on my 2005 Chevy Trailblazer is always on "E" and the empty indicator light is always on, even after I have filled up my gas tank. This problem has been going on for about 2-3 weeks now. I read some statements online that several GM owners of 2005 Trailblazers are having the same issue, causing me to believe that the issue lies with the car itself.

I have a 2005 Chevrolet Trailblazer with a defective gas gauge. Regardless how much gas in the tank the gauge reads 1/4 tank or less, most of the time the low fuel light is lit indicating there is no gas in the car. I am reluctant to pay the $900 to repair this as there is ample evidence the replacement part is no better than the original and the condition returns within weeks. This part is defective and needs to be replaced with a functional gauge.

The contact owns a 2005 Chevrolet trail Blazer. The contact stated that the fuel level gauge would continuously read inaccurate fuel levels causing the vehicle to stall intermittently without warning. The failure would occur even when the fuel tank was full with gasoline. The dealer advised that the fuel pump would need replacing. The fuel pump was replaced three times to no avail. The vehicle was not further repaired. The failure mileage was 50,000 and the current mileage was 120,000. Updated 12/01/10. Updated 12/07/10

While driving, the gas gauge when from nearly full to empty, causing the low fuel warning light to come up. It then intermittently when from empty, back up to full, and then down to reading empty again. The vehicle was serviced with a full tank of gas the day prior and had only been driven for several short errands around town. This has occurred both times the vehicle was driven on Aug 17th. Today (Aug 18th)we took the vehicle around the block for a test drive. It started out reading full tank. At about 30mph is dropped to empty. While sitting in the parking lot when getting home, the gauge was going up and down. An online search shows that the likely cause is the fuel sending unit. This is apparently a well-known issue with 2005 Chevy Trailblazers. There were also several reports of vehicles actually shutting off while driving due to the vehicle believing it was out of fuel when it was not. Chevy refuses to acknowledge there is a problem, but is happy to take your $800 for the repair. Another cause could be the stepper motor for the gauge, which from online research appears to be another known issue with the Trailblazer that GM refuses to acknowledge.

2005 Chevy Trailblazer. Fuel gauge does not work properly. Have to keep track of mileage to get an idea of how much fuel is in tank. Gauge usually reads empty, with low fuel light on, even when filled up. Wife ran out of gas on busy street. Checked around, and found many, many other complaints of the same problem.

My 2005 Trailblazer fuel gauge suddenly stopped working. It always reads no fuel now even after filling up. I have read online and it seems many consumers are having this issue and GM wants over $1,000 dollars to fix. Please look into this as this could result in my vehicle stalling or running out of gas. Thank you.

Fuel level component does not accurately measure fuel levels in gas tank and could lead to unexpected stalling on highways and roadways which could result in collision when gas runs out but gauge says it is full. It fluctuates every time vehicle is turned on and after tank is filled and car turned on, gauge reads empty for several days and then changes to full.

The fuel tank sensor in the vehicle is defective. After putting approximately $50 worth of gas in the tank the low fuel light goes on and the gas gauge does not move out of the low fuel position. This is a serious safety concern for obvious reasons.

Without warning the fuel gauge has completely stopped working and the low fuel indicator light stays on all the time. I have not replaced any parts as it is quite costly and my mechanic suggested I research a recall for this problem as it is quite common in these vehicles. I am afraid I will forget to reset my mileage one time and run out of gas, causing a traffic hazard and possibly an accident.

This goes with the Office Of Defects Investigation NHTSA action number: DP10001. I have a 2005 Chevrolet Trailblazer. This is the second time the fuel area of the vehicle is having to be repaired. My fuel sensor is no longer working. This area of the vehicle is defective and, according to my search on the internet, many, many people have had the same issue (some multiple times) with the 05 Trailblazer. This could result in the vehicle running out of gas without warning which could result in an accident. I have spoken with GM on multiple occasions regarding this issue as well as the oil gauge not working. As stated, this will be the second ~$500 repair on the area of this vehicle.

My 2005 Trailblazer has a problem with the fuel tank level sensor. When I fill it sometimes it says there is gas other times it bounces all over the place. I have owned many cars before & this has never happened with only 40,000 miles on the car. This is a safety issue. I ran out of gas on the street when it occurred. Myself or anyone could have been on the freeway when it happens. Please take a look into this it seems to be common place for these vehicles.
