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.

Twice now the vehicle has run out of gas while driving at highway speeds and the gas gauge still shows a quarter of a tank. This past week we started to notice the gauge reading has been going up and down in 1/4 tank intervals and we aren't quite sure how much gas is actually in the tank. We have an appointment scheduled with our dealer, but felt this problem should be reported as others with the same vehicle are having the same issue.

Driving to work gas gauge showed 1/4 tank of gas. Engine stalled and had to wait for 2 hours before tow truck came. Tow truck operator asked if I ran out of gas. I told him I had a quarter tank left. He suggested putting in 2 gallons and try to start, which it did. Fuel gauge started showing erratic behavior and has since stopped working entirely.

The contact owns a 2007 Chevrolet Trailblazer. While driving approximately 30 mph the fuel gauge reading began to fluctuate. After the reading began to fluctuate the contact fueled the vehicle and the empty fuel tank warning light illuminated. The vehicle was taken to an independent mechanic where a new fuel level sensor was installed. The vehicle was repaired. The approximate failure mileage was 32,000.

I have a 2007 Chevy Trailblazer, for the last year I have been having problems with my SUV wanting to stall. I had my fuel pump/gauges replaced 1 year ago because my fuel gauge did not work at all. I was told that the fuel gauge is read by a portion of the actual fuel pump that is inside my fuel tank. That cost me more than $600 out of my own pocket since they had to remove my fuel tank to replace it. My fuel gauge has been working fairly normal up until yesterday, on my way to work at 6:15am my vehicle stalled in the driving lane of a 2 lane frontage road because I was out of gas. Thankfully, the road was not extremely busy at that time of morning. However, my fuel gauge still showed that I had almost 1/2 tank, when in fact my car stalled because I ran out of gas. I hope that some kind of resolution can be agreed upon with GM to get the problem corrected so that it does not happen in the future.

Fuel gauge failure on my 2007 Chevrolet Trailblazer. Filling the fuel tank turns the low fuel notification light and chime off for about 50 miles, then the gauge goes to "E" and the fuel warning light and chime sounds until the tank is filled again and the process repeats itself. I currently use my trip odometer to monitor the fuel level but my husband has forgotten to reset the trip odometer and ran out of fuel. This is a potentially serious malfunction that should be remedied by the manufacturer. Running out of fuel in the middle of a 60 mph freeway is quite dangerous and maybe more so than running out of fuel on a mountain pass, where it could be miles and hours before help arrives. Chevrolet's "wear & tear" excuse is nonsense for a poorly made part. I had the problem diagnosed at a dealership and Chevrolet said it is not covered under my warranty and the dealership would charge me in excess of $1000 to fix the problem!

The contact owns a 2007 Chevrolet Trailblazer. After refueling the vehicle, the contact noticed the fuel gauge displayed an inaccurate reading of empty. As the contact continued to drive, the fuel level gauge began to rise and display various readings. The contact stated that the fuel gauge was always inaccurate.

At 58,000 miles the gas gauge on my 2007 Chevy Trailblazer stopped working. My check engine light went on, so I took into my authorized Chevrolet dealer. They charged me $95 dollars and said that it was a dirty throttle plate. A note on my receipt said that a faulty gas gauge could cause the light to come on. The gage fluctuated between full to empty for awhile, but now it does not work at all. I have to use my trip odometer set to 300 miles to estimate when I have to fill up with gas again. This is a dangerous situation, because I never know if when the engine light comes on if it is the gas gauge or something more serious. It can be a serious problem when driving on the expressway or a long trip. I did complain to GM on case #[xxx], but they refused to fix the problem.

I own a 2007 Chevy Trailblazer. For about six months now every time I fill up with fuel the gage stays on empty and the low fuel light comes on. After driving 30 to 50 miles the light goes out and the fuel gage works until the next time I fill up and the same failure repeats itself. I have not had any accidents or run out of gas because of this. However, I do not trust the gage and have gotten in the habit of filling up when the fuel level gets down to one half tank.

Fuel gauge reads empty when the tank is half full or less. It registers low fuel. I had to replace the sender float assembly to fix. GM dealership said it was not covered by a recall and it was out of warrenty due to milage.

Mar 012009


  • 55,000 miles
I purchased my 2007 Trailblazer in August 2007. Starting around March 2009, the gas gauge began failing. I would fill the tank but the gauge would only register half a tank. Eventually, the gauge completely quit working and sits on empty all of the time. As a result of this equipment failure/defect, my vehicle died once because I did not know I was out of fuel. Because my vehicle had just gone out of warranty (50,000 miles), it was not covered by the dealer and I could not afford to replace the gauge, or fuel sensor, whatever the problem may be. Since that time I have to follow the number of miles I put on the vehicle per fill up.

A couple months after I bought my used SUV I noticed the gas gauge jumping around. Sometimes it would read appropriate (guessing now) and sometimes it wouldn't move off 'E'. the gauge jumped around for a couple weeks then just quit working. I had to start keeping track of my mileage on paper so I could guesstimate when to put gas in. I got a quote on fixing this issue and was told it would cost me between $400-$800 to fix. I called the dealer I bought SUV from and asked them if they would take care of the problem and they told me flat out 'no'. they told me I could bring it in and have it fixed and pay for it but they wouldn't stand behind it. I was on my own. Since I couldn't afford to have it fixed I had to drive it this way for months, always writing down mileage and gas fill-ups. I finally had this repaired on 1/11/11 - it cost me $379.83 to get it fixed. I don't feel I should've been responsible to pay for this repair. I have read numerous places about the '07 Trailblazers having this problem, along with confirmation from the garage that "this is a common problem with the '07 Trailblazer". the dealer I bought my vehicle from wouldn't return my phone calls or inquiries about how to report the problem or anything, they just shrugged their shoulders and didn't care and I had only had the vehicle for 3 months...

Started noticing that when I would fill up, it would show that I was empty. Then after putting about 40 miles on the tank of fuel it would start showing correctly. I dealt with this for about a month and then it showed that I had a 1/4 tank of fuel but I actually ran out of gas in the middle of an intersection. After that I took it to my mechanic and it was $300 to repair.

  • 71,000 miles
The fuel gauge reads wrong. I have ran out of gas multiple times because the gauge reads having more fuel in the tank than it does. Sometimes the gauge will read full then go to empty and back again within a few miles of driving. I'm afraid to go on any long trips because of the fear of running out of gas. It happened to me in an intersection and was almost T-boned by another vehicle because I could not accelerate. The other vehicle was able to swerve and avoid a collision.
