1 Other Fuel System Tank Assembly problem

Failure Date: 09/05/2020

Fuel gauge drops to empty constantly, even where there is half a tank. Only 5-10% of the time it shows how much fuel there really is. This happens while traveling and while stopped.

2 Other Fuel System Tank Assembly problem

Failure Date: 06/27/2020

The gas gauge shows empty even after the tank is filled. Other 2005 Trailblazer models have had a recall on this issue regarding the gas gauge and sensor but my model did not. It also causes the check engine light to come on after putting fuel in the gas tank. The gas gauge shows empty at all times ( when your moving, and stationary). Not accurately knowing how much gas is the vehicle can cause you to stall out while on city streets or on the highway driving 60 mph.

3 Other Fuel System Tank Assembly problem

Failure Date: 03/01/2018

The whole instrument cluster does not work anymore, does not let me know how fast I'm going or how much fuel I have, oil pressure gauge doesn't work, temperature gauge doesn't work. . . Why hasn't this been recalled? this is very dangerous, considering I have 4 kids that are constantly in the car with me and I have no idea what is going on with my vehicle?? and it also tells me that my fuel level is low, even after I fill my tank. This seems like a very common problem in these vehicles, why has it not been considered a safety issue????.

4 Other Fuel System Tank Assembly problem

Failure Date: 01/05/2018

I can't tell if my tank is full or empty.

5 Other Fuel System Tank Assembly problem

Failure Date: 07/01/2017

The fuel level sensor is a very common problem. The tank is filled full but it will always read empty. I already have a refurbished cluster so it will not be the cluster's fault. Gm needs to recall the fuel level sensor to be fixed to avoid accidents on the road.

6 Other Fuel System Tank Assembly problem

Failure Date: 06/12/2017

The gas gauge is not working and the fuel light stays on even when the tank is full of gas. Vehicle was stationary at a gas station when fuel gauge malfunctioned.

7 Other Fuel System Tank Assembly problem

Failure Date: 02/18/2017

Fuel gauge sensor not working properly. When fueling up, the gas gauge falls to 0, after turning the vehicle on and the low fuel sensor light comes on and dings. After a few miles the gauge goes to 1/4 of a tank indicating there is gas, but not indicative of actually what is in the tank. I have tried to reset my tripometer every time I fuel up, and then stop at the gas station and refuel every 240 miles. However this past weekend I ran out of fuel and the vehicle came to a stop on a major highway. I know now that this is also unreliable and will make it a point to stop at every 200 miles.

8 Other Fuel System Tank Assembly problem

Failure Date: 12/27/2016

My 2005 chevy Trailblazer ext is leaking gas from the gas tank underneath the vehicle when the SUV is running.

9 Other Fuel System Tank Assembly problem

Failure Date: 10/10/2016

Fuel gauge was on 1/2 tank. I went to the gas station to fill it up and all of a sudden the gauge meter went to the left and read "empty" and the low fuel light came on even though I had a full tank of gas. I restarted the truck and the fuel gauge meter still read low (less than a 1/4 tank), it eventually returned the to the 1/2 gauge/meter mark. Car was stationery at the gas station at time of the incident, then I eventually drove off at low speed.

10 Other Fuel System Tank Assembly problem

Failure Date: 01/28/2016

I went to the gas station and filled up my tank. I started my car and the gauge was not at the fill line. The gauge just bounced up and down and then went below the empty mark making the chime go off and the car red "fuel is low". This was on a secondary city street.

11 Other Fuel System Tank Assembly problem

Failure Date: 10/15/2014

Lights go out/dim while driving. No additional electrical items in use-heater, ac, gps, radio, cigarette lighter. Does not appear to be affected or caused by speed, acceleration, deceleration. Fule tank will sometimes register empty while mostly full. Do not notice problem during daylight driving.

12 Other Fuel System Tank Assembly problem

Failure Date: 05/03/2014

On may 3, 2014, I filled the gas tank up, and began to exit the gas station. The fuel gauge showed less gas in the tank then when I began fueling. After several miles the gas gauge showed slightly more gas, but was still not providing an accurate reading. After shutting down the vehicle I checked the gas gauge, and it was still not working properly. I've been reviewing online complaints through the NHTSA website, and this appears to be an ongoing problem with the 2005 chevy Trailblazers resulting in accidents. I'm very grateful. I observed the problem before stalling in an intersection or other dangerous location with my three small children in the vehicle.

13 Other Fuel System Tank Assembly problem

Failure Date: 02/08/2014

I just purchased this vehicle yesterday from a dealership. They filled the gas tank up before I drove it off the lot because, they said, "the gas gauge isn't working. " I was looking up what it could be and noticed there was a lot of people with complaints of this, 668 people. I suppose I'm the 669th person. There wasn't a recall that I could find, but investigations were being done?.

14 Other Fuel System Tank Assembly problem

Failure Date: 02/04/2014

Approximately 5 or 6 months ago I started noticing when I would fill my tank, the fuel gauge would not register full. I took my car to the dealership and they told me it was the fuel sensor that wasn't working. They told me it would be $600 for a new one. I couldn't afford that, so now I use my mileage indicator as to when I fill up.

15 Other Fuel System Tank Assembly problem

Failure Date: 01/06/2014

While sitting at a stop light, the fuel gauge stopped working. The gauge went all the way down to "e" and the low fuel level indicator appeared on the display. Now when I fill up the tank, the gauge reads empty and after I drive about 20-30 miles it will move up to about 1/4 tank but no higher and sometimes it will still move back to empty that slowly move back up. Also sometimes the oil pressure indicator will drop all the way down while idling or in park and the low pressure indicator will appear, but as soon as the gas is pressed, the pressure will go back to normal. Also, about 1 1/2 years ago, the keyless entry/alarm/back liftgate lock and license plate light all stopped working simultaneously. I was told that it is probably a grounding wire issue but not definitive. Now my liftgate will not lock at all.

16 Other Fuel System Tank Assembly problem

Failure Date: 10/23/2013

My 2005 Chevrolet Trailblazer shows empty when vehicle is filled up, this lasts until close to a quarter tank has been used; frequency: 100% of the time. Contacted prior owner and he confirmed it had been doing it off and on since 2 year of ownership but dealer could not duplicate. Took to Chevrolet dealership for diagnostic and was told its the fuel sending unit, a common problem in my year in particular. Vehicle also is beginning to have issues with showing correct fuel left when it drops below a quarter tank, it does not drop consistently which would lead to my running out of gas if I trusted it, to date I fill before it gets to a quarter tank to avoid the problem.

17 Other Fuel System Tank Assembly problem

Failure Date: 10/02/2013

After filing the gas tank, the check engine light and low fuel light came on and the fuel gauge registered empty within minutes of leaving the gas station. It has continued to be malfunctioning like this off and on over the last month. I have heard of 2 other people I know, with the same make, model, and year vehicle with the same problem. Is this a recurring problem nationwide with other owners of this vehicle?.

18 Other Fuel System Tank Assembly problem

Failure Date: 05/01/2013

Gas gauge does not read correctly, light stays on even after a full tank of gas.

19 Other Fuel System Tank Assembly problem

Failure Date: 03/18/2013

I had just filled up my SUV, and while on the highway, my fuel gauge started dropping within a minutes time, to 3/4 tank, 1/2 tank, 1/4 tank, then the fuel light came on and stated I was on empty. I didn't smell gasoline, but the gauge then started going back up, then down and went haywire. After some of the gas was used, it went back up to almost full, but after a bit, it dropped back down to half tank again. Every subsequent time I fill up, the gauge does the same thing. Another incident that has been happening for the last few years is the head lights dim and get brighter. This doesn't happen all the time, but at least three times a week. I didn't think too much about it until I saw other complaints on this website about the same thing.

20 Other Fuel System Tank Assembly problem

Failure Date: 03/04/2013

Filled up gas tank only to find that it was reading empty. Fluctuated between empty and 1/4 tank. Ran out of gas with children in vehicle at one point in very bad weather. Finally able to save $450. 00 to have it fixed. Is it true that gm will pay for half of the repair bill? very upset with general motors!!.

21 Other Fuel System Tank Assembly problem

Failure Date: 03/01/2013

The contact owns a 2005 Chevrolet Trailblazer. The contact stated that the fuel tank displayed a fuel level reading of empty after refueling to capacity. The fuel sensor light was also illuminated. The vehicle was taken to the dealer, who stated that the fuel sensor needed to be replaced. The vehicle was not repaired. The manufacturer was not notified. The failure mileage was 76,000.

22 Other Fuel System Tank Assembly problem

Failure Date: 01/18/2013

Ran out of fuel once on highway, when gauge showed tank was full. In Jan/Feb the gas gauge just stopped working even when completely full of fuel it will show only 1/4 of a tank or none at all. The radio works only intermittently will work then stop working unexpectedly. Headlights are always burning their connection, short circuiting my headlights pretty frequently.

23 Other Fuel System Tank Assembly problem

Failure Date: 01/03/2013

While driving to work I felt my truck lose power a few times while slowing to stop as well as taking off after a complete stop. My fuel tank was approximately half full and it kept feeling like I was running out of gas. This really scared me because I was in the middle of heavy traffic and trying to accelerate it finally kicked in and I almost ran into the person in front of me. Please let me know what I can do about this? thank you very much.

24 Other Fuel System Tank Assembly problem

Failure Date: 10/01/2012

Gas gauge does not work properly. Will not register gas in tank.

25 Other Fuel System Tank Assembly problem

Failure Date: 09/19/2012

I have a 2005 tb LS, and it's a pos. As soon as I drove off the lot I've had nothing but issues. My brakes pulsate, go to the floor, get stiff as a board, basically they don't work. I have to pump the brakes quickly in an effort to avoid a crash. I filled the gas tank to full, huge mistake. The moment I did that the check engine light has flashed and sporadic idling. It has a loud whine under the hood, front turn signals and hazard flasher randomly stopped working. Car will die if I run the a/c for more then 15 mins. It will pull to either side when I apply my brakes. I have always kept up with proper maintenance, tune up, etc. This is absolutely terrible, that so many have the same damn issues and yet chevy will not recognize/take responsibility for their obvious flaws and lack of mechanical knowledge. . I just want out of this damn lease and a replacement car!!!.

26 Other Fuel System Tank Assembly problem

Failure Date: 06/25/2012

Fuel gauge does not accurately show the right level of fuel in the car. Fuel light comes on when tank is full. Fuel gauge shows full tank when empty. This has caused two cases o car breaking down and being stranded. One incident almost caused car to be rear ended on busy highway.

27 Other Fuel System Tank Assembly problem

Failure Date: 06/01/2012

While driving on the highway the other day my gas gauge in my 2005 Chevrolet Trailblazer showed that my gas tank was in between half and quarter tank of gas. I was going approx 60-65 mph on the highway and the vehicle stalls due to being out of gas!!!! I get it towed to a gas station and fill it up when I start my car now it shows that there is no gas in the car when I just filled the tank. This is a major problem as I had my young child in the vehicle with me when the stall on the highway occurred. Not a happy person these days!!.

28 Other Fuel System Tank Assembly problem

Failure Date: 05/31/2012

Fuel gauge was showing low fuel level, I filled up the tank and the gauge went to empty and said fuel level low warning.

29 Other Fuel System Tank Assembly problem

Failure Date: 02/05/2012

The fuel gauge does not work. The fuel gauge sets on empty regardless of how full the gas tank is.

30 Other Fuel System Tank Assembly problem

Failure Date: 01/11/2012

When my gas gauge stopped working, it showed I had fuel in my tank, turns out I did not. I ran out of gas while on an interstate in maine. . In the dead of winter, at night, on icy roads, traveling at approx 35 miles an hour. As all of you know, when you run out of fuel, the power steering & braking shut down and the vehicle can be very difficult to maneuver as well as very dangerous. . . Especially on icy roads in maine in January. I am a young lady and happened to be all alone when this occurred and not to mention I was about 15 miles away from the nearest gas station. . So needless to say I was not happy. I wasn't about to hike the interstate, by myself in freezing cold weather at night. . I do not have a death wish. Although I had to sit in my vehicle, where I had no heat, due to no fuel, and wait for over an hour for my dad to come rescue me. This is not right, and it is not the consumers fault, this needs to be addressed by gm, because as you've heard by me, and many others, it's a huge safety issue, and they need to fix this problem. Some of these complaints go back into 2007, it's now 2012. . What are you waiting for?? fatal accidents because of your stupidity? make it right gm. You have not heard the last of this. . .

31 Other Fuel System Tank Assembly problem

Failure Date: 07/20/2011

Refueled with gas and gauge did not go up. Ever since, gauge does not show proper level of gas in tank. Got a letter from gm but they want me to pay half to repair it which total cost is $266. 00 my cost is $133. 00 gm knows this is a problem and should offer a total recall instead of a rip-off of 50-50 to the customer.

32 Other Fuel System Tank Assembly problem

Failure Date: 07/04/2011

Gas gauge stopped working about 2 years ago. Shows as empty even when the tank is full. It's very frustrating as you have to always remember to fill up to to count the miles. I received a letter from chevy a couple of years ago letting me know that they are aware of the problem and will cover 50% of the cost of getting it fix. But why do I have to pay at all? it's not my fault, I should not have to pay at all.

33 Other Fuel System Tank Assembly problem

Failure Date: 05/27/2011

Tl-the contact owns a 2005 Chevrolet Trailblazer ext370. The contact dispensed fuel into the fuel tank, and the fuel gauge displayed an empty reading. The vehicle had not been diagnosed or repaired. The manufacturer was not made aware of the problem. The failure was approximately 44,000. The VIN was unavailable. Js.

34 Other Fuel System Tank Assembly problem

Failure Date: 04/15/2011

I had recently purchased the vehicle in April of 2011. I stopped after getting paid on a Friday to fill up my tank and when I go to turn on my vehicle the gauge goes to full and just drops all the way to empty. Since than I've had the same problem running out of gas in the streets dozens of time. I tried using my trip but my mph aren't always accurate I don't even know how many gallons my tank holds. Being stranded for awhile with my children is really tough. I can't just afford to pay over $500 to have my problem fixed just because gm won't be responsible enough to do a recall.

35 Other Fuel System Tank Assembly problem

Failure Date: 03/15/2011

I drive a 2005 Chevrolet trail blazer. The gas gauge is wildly inaccurate. In fact, when I was driving the vehicle, I ran out of gas. It was in the evening during the cold michigan winter and I had my 6 month old daughter with me in her car seat. The gauge does not provide me with an accurate idea of how much fuel is left in the tank and I am forced to either use my odometer or just make an educated guess. This is a safety hazard which needs to be addressed.
