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.

Please take a moment & say thank you by donating $5 or whatever you can to the Center for Auto Safety.

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 started fluctuating between full and empty, now it just stays on empty. 09-09-2011 with car in park the idle sometimes goes up to 2100 rpms then will go as low as 600 rpms, recently as of 09-16-2011 I have been noticing a fluctuation in speed on its own or without my assistance.

The fuel gauge light went on when the vehicle still had nearly 10 gallons of gas. The fuel gauge will read full for a week and then the fuel light when come on suddenly. There have been multiple occasions when the fuel gauge read empty, but I was only able to fill up with 8 gallons (fuel tank is 20 gallons plus). Fuel gauge has been so inaccurate that I have been forced to use my trip odometer and I don't feel confident taking car on a road trip or out of town.

Fuel gauge shows empty, while there is still plenty of fuel in tank. When the vehicle is first started, the gauge reads correctly, but as soon as the vehicle is in motion, the gauge drops to empty. When tank is 100% full, the gauge reads correct until around 100 miles, when the gauge immediately drops to empty. Online research is showing this to be a known issue, possibly with the fuel sending unit attached to the pump.

I own a 2007 Chevy Trailblazer. The fuel gauge started fluctuating erratically and the gas light would come on and stay on. Then eventually it stop working altogether. My wife has ran out of gas in it one time. From the complaints I've been reading. I'm not the only consumer experiencing this same problem. I have called dealerships about this repair and it will be very expensive to fix it. I feel the manufacture should step up and fix their problem. Its obvious that you have one. My family only purchases general motor products. Please let us keep our relationship healthy.

Fuel gauge keeps showing empty when I know there is fuel in the vehicle. The faulty gauge goes from half full to the empty light (warning) coming on after driving less than 10 miles. This has been going on for about 3 weeks and just yesterday I received a letter from GM saying they will cover 50% of the cost to repair. It's faulty equipment and GM should put a "recall" in place and cover the total cost to repair!

The contact owns a 2007 Chevrolet Trailblazer. The contact stated the fuel gauge failed to display an accurate reading with fuel consumed in the fuel tank. The manufacturer mailed a notification offering to reimburse fifty percent towards the fuel level sensor repair expense. The failure was not diagnosed nor was the vehicle repaired. The manufacturer was not notified of the defect. The approximate failure mileage was 52,000.

Fuel gauge no longer reads correctly. Problems began several weeks ago with a gasoline fill up. The gauge did not read correctly (empty) but righted itself after several miles. The gauge no longer corrects itself and reads empty practically all of the time, even when there is sufficient fuel in the tank.

2007 Trailblazer at 51000 mi. Fuel gauge reading incorrectly after filling it would read ok for aprox. 100mi. Then drop to empty. Now 10,000mi later it is permanently on empty. I am driving using the trip meter. I think this should be recalled for safety reasons.

Fuel gauge on my 2007 Chevy Trailblazer does not give consistent readings. The needle moves up and down and signals the tank is empty while the vehicle is in use regardless of actual fuel level. This occurs every time I drive the vehicle. I am looking to fix the issue.

Filled by my 2007 Chevy Trailblazer yesterday and the fuel gauge reads empty and the fuel light stays on. Took my vehicle to the dealer and was told that I missed the warranty by 3,000 miles and it will be almost $800 to repair. Have read online that hundreds of consumers are experiencing the same problem with the same type of vehicle from 2005-2007 so there is obviously a defect in the manufacture. This needs to be looked into and handled, it is obvious the dealer needs to recall these vehicles and correct the problem.

Fuel gauge on the 2007 Chevy Trailblazer has failed at less than 40,000 miles. Not knowing the level of fuel is a definite safety hazard. Problem is very common according to dealer. Cost to repair is from $600 to $1,000. GM should be made to recall these vehicles.
