Print this page 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.

Trailblazer 6-cyl

  • 40,000 miles


In my 2006 Chevy Trailblazer, the gas sensor does not work and caused the check engine light to come on intermittently as well as causing the fuel gauge to remain on empty regardless of the actual fuel level. I have had the car diagnosed and was informed that it was the sensor in the gas tank and the repair would cost me $500 to replace a part that would ultimately fail again. GM has refused to cover partial expenses of this repair even though they are aware of said problem. I first notified GM on 6/23/2009 and they have yet to issue a recall. There is currently an open investigation :action number DP10001.

The fuel sensor for my 2006 Chevy Trailblazer went out so it reads empty all the time. Doing internet research it seems this is a common problem with the Trailblazer and is a safety issue. I have children and live in a extreme weather climate.

The gas gauge began to malfunction, indicating that the tank was empty when it was not or inaccurately measuring the amount of fuel. This also triggers the engine light to go on and now happens consistently when the vehicle is turned on. The vehicle has 60,000 miles and the part was replaced for $530.

Fuel gauge malfunction. Fuel gauge will register as empty whether there is gas or no gas in the tank. Gradual degradation. This also cause the check engine light to become engaged frequently. Approximately $700 to resolve problem.

2006 Chevrolet Trailblazer. The gas gauge shows the tank is empty even after fill up. The gauge will then go up and down from full to empty and back again. Have already ran out of gas when it first happened, the gauge showed less than half a tank and then showed no gas, but I was empty and dead on the road with the baby in the car in the middle of the night, alone.

I have just under 40,000 miles on my Chevrolet Trailblazer and the fuel level sensor began malfunctioning. It reads empty when the tank is full and even jumps from full to empty to full again.

I am the un-proud owner of a 2006 Chevy Trailblazer. The gas gauge quit working after getting gas one day. The gas light and my service engine light now stay on consistantly. I was told it will cost me around $800 to repair - $600 for labor and $200 for parts. I live in a rural area and a snowy part of the states and have a small child - this needs to be a recall issue. It is not safe to "guess" how many miles you can go on a tank of gas.

My 2006 Chevy Trailblazer had only 60K miles on it when the fuel gauge quit working. It always reads empty so I have no way of knowing how much fuel remains in the tanks. I understand that many Trailblazers are having this problem.

  • 40,200 miles
The contact owns a 2006 Chevrolet Trailblazer. While driving approximately 70 mph, the vehicle stalled without warning. The failure was contributed to the lack of gasoline in the fuel tank. Roadside assistance was called to the scene. The contact stated that the fuel gauge displayed inaccurate readings at any fuel level capacity. The vehicle resumed normal operation after gasoline was added to the fuel tank. The vehicle has not been repaired. The failure mileage was 40,200 and current mileage was 60,000.

  • 55,000 miles
Traction control lights on and off intermittently. I had a sensor replaced that was located in the steering column behind the airbag and that worked for a few weeks but it is back to going on and off. That sensor and labor cost me $500 total because I had to have it looked at 3 times. Fuel gauge always reads empty. I have done some research on the fuel gauge problem and there are a ton of the same problems out there. This should be a recall immediately. I have to get the fuel pump and sensor replaced at a cost of $800 to $1000. The trouble started at about 55,000 miles. Shame on Chevrolet for letting this go on. They know about the problem and wont do a recall to help the little guy. All I've ever owned is Chevy's....but no more!!!

Fuel gauge stopped working at 49,000 miles. Fuel gauge reads all over the place and trips a code off and on for faulty fuel sending unit. I have to set trip meter to track fuel. I know other people with same year Trailblazer with the same problem. Can run out of fuel at any time during any conditions if not kept in check. Not an easy or cheap fix! fuel tank needs to be dropped and fuel sending unit replaced. Not something the average person can do.

Upon filling my gas tank at a local gas station, the check engine light came on and my gas gauge began to go haywire with many fuel level fluctuations. My local dealer told me that my gas cap was defective, which I then replaced. The check engine light went out a few days later, but my gas gauge continues to malfunction. I am now told that a replacement of the sensor will cost between $800 to $1000 and that my extended warranty does not cover this. Internet research has revealed hundreds of similar complaints. This company has received my tax dollars for a bailout only to expect more money for a defect that is obviously poor quality parts and workmanship.

  • 40,000 miles
I currently own a 2006 Chevy Trailblazer. I had just hit the 40,000 mile mark and started having problems with the gas gauge reading empty and the check engine light staying on. I was told to replace the gas cap due to a possible vacuum seal no longer working, that did not correct the problem. I am now tracking my mileage in order to know how much gas I have because as a working mother of three, I cannot not afford the $900 - $1000 to repair the issue. This is definitely a recall issue that should be addressed by GM.

After leaving the gas station with a full tank, I noticed that the gas gauge was registering empty. After a few minutes it read full. The next day it read empty again even though I had not driven the vehicle more than 10 miles after the fill up. It read full again a couple days later and now it doesn't work at all.
