I own a 2007 chevrolet trailblazer. The fuel gauge indicator remains illuminated no matter how much fuel is in the tank. As a result, my wife and I are never fully aware of the amount of gasoline left in the fuel tank. I believe it to be a defect as so many other people online is experiencing the same issues.
2007 Chevrolet Trailblazer fuel system complaints
Page 10 of 12: complaints 251 to 280 of 311, newest first, as owners wrote them.
Upon filling up the gas tank on the vehicle, the gas gage dropped to "empty". The gas gage then went to half and returned to empty several times. The gas gage finally returned to full, the correct level. However, several minutes later, while traveling over a narrow two-lane bridge, I was startled by the sound of a warning chime. While trying to identify the source of the warning I was distracted and almost caused a collision on the bridge. It turns out that the gas level had returned to the empty level even though the tank was full. The "check engine" light subsequently came on. I did some on-line research (google "trailblazer fuel defects") and found hundreds of comments from trailblazer owners who had exactly the same problem. The year of vehicle ranges from 2003 to 2008. Many of these owners state that due to the defective gas gage they had run out of gas while in motion thereby endangering themselves and others.
Fuel level gauge fluctuates from low fuel to accurate fuel level once actual gas level reaches approximately 1/2 tank.
Gas gauge is irratic after filling up. I believe it is a faulty fuel level sensor.
The fuel tank sender stops working when the fuel level in the tank reaches half full. It occurs every time the tank reaches half full.
2007 trailblazer gas light comes on when fuel tank is full. This needs to be a recall due to fact vehicle could fail on road in freezing conditions. Lives could be in danger for faulty reading or for engine failure due to improper sensor working. Apparently this has happened to many people with even 2005-2006 models. It is not covered under warranty. There needs to be something done about this for safety of the public!!!!!!
Tl*the contact owns a 2007 chevrolet trailblazer. While driving at any speed, the contact noticed that the fuel gauge would indicate inaccurate fuel levels. The dealer was informed and they advised the contact to bring the vehicle in for diagnostic testing. The manufacturer was notified and the contact was awaiting a response. The vehicle was not repaired. The current mileage was approximately 24,453. The failure mileage was approximately 24,000.
2007 trailblazer fuel level sensor failure causes my fuel gauge to give incorrect reading. I would fill up the car with gas and the gauge would go to 1/4 tank or empty at times and then back to full. I brought this vehicle brand new and at 65,000 miles this issue started. My extended warranty ended at 60,000. I ran out of gas once because the fuel level display showed that I had 1/4 tank when I was on empty. I took the vehicle to a local chevy dealership and was told there's a shortage in the sensor and it has to be replaced, but since my warranty is no longer it would cost over $600.00. I know of 3 other people with the same sensor failure and after reading reviews online I believe chevy needs to recall this sensor.
When I start my vehicle, gas gauge rises to actual gas level. After 3-4 minutes of driving, gas gauge drops to empty, and remains until truck is restarted. Sometimes the gauge will rise to one-half tank, and stay as well. On one occasion, I was stranded on the interstate with my 4 year old son and my wife. The gauge was stuck a half tank, but I was actually out of gas. 4 hours later I was back home. On some level I think that constitutes a safety hazard. I called my local gm dealership and said it was most likely a fuel-sending unit inside the tank, and it was not covered by my power-train warranty. Was told it would be between $600-$900 to replace. Ridiculous!!! I have read hundreds of similar issues to the same make and model of my trail blazer. It is time for gm to allow these to be replaced under the 100,000 mile power train warranty. This may not qualify as a safety recall, but surely a defect that gm needs to address!!!
At approximately 52,000 miles my fuel gauge broke. It first began when the vehicle was at less than 1/2 tank I could see the needle drop to e in a matter of minutes. Now, it doesn't matter if the tank is full or half empty it always registers on e. The light continues to beep and now my check engine light is on! I cannot believe gm will not recall the trailblazer due to this issue, the dealer sure don't disclose this faulty problem when they are trying to sale you the vehicle!!!
Fuel level sensor failing.
I own a 2007 chevy trailblazer and the gas meter in the blazer says it empty when I just fill it. Now when I drive the light beeps and stays on. I have researched this problem and I see I am not the only one who has this trouble with my blazer. I cant believe there was not a recall on the sensor in the gas take. I contacted my dealer I bought the car from and explained the problem and they said that it not covered in the bumper to bumper warranty I bought for the vehicle. It cost over $1,000 to fix it. I feel that if I am not the only one with this problem, I see there is alot of people with this concern about there vehicle. I don't feel now my vehicle is safe and it only has 30, 000 miles on it.
I was at sams club filling up my vehicle when the gas gauge went to empty and the light came on. The gas gauge thereafter began fluctuating and continues to do the same. Most of the time it starts out showing an inconsistent reading then goes to empty. Fuel descending unit gone bad. An inquiry on the internet reveals a large quantity of trailblazers have the same issues. The dealerships are also very familiar with the issue. My vehicle had 49,000 miles and some change with this first occurred. Can you imagine running out of gas in a rural area with or without kids with no help in site, or even worse in a urban high crime area passing through. Gm has failed to issue a recall for this problem despite the large quantity of vehicles exhibiting this problem. I found the average mileage was 52,000 when this occurs. This repair is rather costly requiring the gas tank to be removed. At this point I am trying to keep up with my mileage, fortunately for me I did not run out of gas when this first occurred.
Gas gauge malfunction.
Fuel level sending unit quit working or reports false level. Particularly happens when I fill up. Check engine light also has come on and when it was checked showed problem with the fuel sending unit.
Gas gauge is faulty. Does not read accurate fuel levels. When you fill the tank the check engine light turns on and then the fuel level will drop to empty and then back up to half tank.
2007 chevrolet trailblazer ss gas gauge sensor malfunction. Fuel level indicator does not function properly and will trigger the service engine light to come on and off on any given day. Vehicle gives low gas indication even after filling up gas tank. If you google this problem or search auto forums, it appears thousands of people have this same issue and no one is doing anything about this.
Tl*the contact owns a 2007 chevrolet trailblazer. The contact stated that the check engine light illuminated consistently and the fuel sending unit failed. Whenever the contact filled the vehicle with gas, the fuel gauge would register an empty reading. The vehicle was taken to an authorized dealer who stated that there were no related recalls and the fuel sending needed to be replaced at the contact's expense. She called the manufacturer who offered no assistance. The failure mileage was approximately 50,000 and the current mileage was approximately 90,000.
2007 chevy trailblazer with 64,000 miles. Fuel gauge will move around no matter how much gas in it. Could have a full tank & one minute it will read full, next minute low fuel light is coming on. 3 times now, my trailblazer shut off going down the road, which means no power steering or power brakes. It thinks it's out of fuel, when there is fuel in it. After sitting a few minutes along side the road, I start it up & I'm good to go. I have to keep it filled all the time, because the gauge will not read correctly. Sometime sitting at idle I've watched it go to empty & back up while I'm just sitting there.
After we fill the gas tank, the needle will go to 1/2 full then as we drive further the needle goes all the way down to empty and the empty light comes on.
The chevrolet trailblazer has several complaints on-line about the fuel gauge not operating accurately and the need for the fuel sending unit needing to be replaced on several vehicles that are relatively new. This is an incredible nuisance. I have owned several vehicles in my life and have never had to replace this part in any car. I now have a 2007 trailblazer and had to spend almost $600 on this part. I am curious why there are so many complaints on line and why there isn't a recall on this?
2007 chevy trailblazer gas sensor has malfunctioned. Found out that it is not under warranty! I have found many complaints about this on the internet. There should be a recall on this part and it should be replaced or covered by my warranty!
The electronics on my 2007 chevy trailblazer have gone out which includes the brake lights and the fuel gauge. The repair on the brake lights was minimal but it will cost over $800 to repair the fuel guage. Chevrolet has known about these problems for years but has not attempted to fix them or recall the vehicles.
Tl*the contact owns a 2007 chevrolet trailblazer. The contact stated that the fuel light turned on intermittently which caused the check engine light to illuminate. The failure occurred even after the fuel tank was full. The vehicle was taken to an authorized dealership where the contact was informed that the fuel level sensor was defective. The vehicle had not been repaired at the time of the complaint. The contact had not spoken with the manufacturer. The VIN was unavailable. The current mileage was approximately 45,000. The failure mileage was approximately 44,000.
The gas sensor on the 2007 trailblazer goes out and the vehicle is not able to pass emission test required by state law. I have researched on line and found several of the same complaints from other trailblazer owners.
Tl*the contact owns a 2007 chevrolet trailblazer. While driving at an unknown speed the fuel gauge began to read as if the fuel tank were empty. Upon refueling the vehicle the fuel gauge operated normally for approximately 15 miles before reading as if there was no fuel in the tank. The vehicle was taken to an authorized dealer where he was informed that the sending unit needed to be replaced. The vehicle was not repaired and the failure continued to occur. The failure and current mileages were 36,000. The VIN was unavailable.
Chevy trailblazer fuel sending unit failed. The gauge starting acting erratically and now does not work at all. It is now extremely difficult to know how much fuel is in the car at any given time.
Gas gauge reads empty when half full, fuel pump replaced.
Gas gauge sensor alarm signals gauge is empty when tank is 3/4 full; have not gotten an answer as to whether the vehicle will become disabled and have to stop to just put in a few gallons. The low fuel indicator signal is very distracting and goes off constantly. Repair cost is $400-$600 for the sensor and is not covered under vehicle or extended vehicle warranty. It is an obvious manufacturing defect and the vehicle should require a recall.
Gas gauge would not work - did not give accurate account of how much gas was in vehicle even after filling up. Gas light was on and would ding as if empty. Took car into chevrolet dealership & it was a sensor in the gas tank. Gas tank had to be "pulled" and sensor had to be replaced. Would have cost me $800, but luckily I purchased an extended warranty when I bought the vehicle. I have seen numerous reports of this same thing happening to others with a 2007 trailblazer - is this not a recall?
