Problems with 2007 Chevrolet TrailBlazer FUEL SYSTEM, GASOLINE

On average, the 2007 Chevrolet TrailBlazer starts to “feel” problems with the FUEL SYSTEM, GASOLINE and its various aspects after 59 777 miles.

Recently reported FUEL SYSTEM, GASOLINE problems on 2007 Chevrolet TrailBlazer

My 2007 trail blazer has a bad fuel gauge which has caused me to run out of gas 3 times over two years. in all of those occasions my gauge reading said i had more fuel in it. now it will completely stop working after half a tank is used. the last incident was 2/11/2011. one of those incidents was reported to police. *tr

The fuel gauge on my 2007 chevy trailblazer is malfunctioning. although there is plenty of fuel in the tank the fuel gauge randomly falls to empty and shows a low fuel message. it is difficult to know when the vehicle will be out of fuel without trying to estimate based on mileage. *tr

My 2007 chevrolet trailblazer's fuel gauge is no longer functioning properly. the vehicle has been receiving all preventive and scheduled maintenance and has approximately 64,000 miles. the problem started approximately two weeks ago (first week of february 2011) and has progressed to the point where it has completely failed. the gauge will indicate proper level when key is turned on but will drop to zero with low level light staying on almost immediately after the vehicle is started even if the fuel tank is full. this makes it very difficult for me to continue to allow my teenage daughter to use this vehicle as her primary transportation to school and work. especially in the winter months where being stuck on the side of road in the country can be a matter of life or death. i have taken the vehicle to the dealership for estimate and the repair will reach between $600-900 since the vehicle is out of warranty. i understand from talking to professional mechanics and internet research that this problem is well documented and known to be the use of substandard parts in the fuel level sensors in the fuel tank. even if my limited research is not conclusive, the number of incidents where this occurs seems to warrant a response from the company. *tr

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.

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. *tr

Faulty fuel gauge/check engine light. *tr

Like many other owners of the 2007 trailblazer, i have experienced failure of the fuel gauge. this is the second time it needs replacement in the four years i have owned this vehicle, and gm is not covering it under the warranty. the gauge goes down to zero and the low fuel indicator chimes. last time around the check engine light also came on. *tr

Fuel gage read 1/4 of a tank and ran out of gas on the side of the road in the winter with two small children in the car. since the incident my fuel gage read all over the board and eventually only reads empty. i have meet many other people with the same make/model with the same issues

Experienced inaccurate fuel gauge readings while driving. *tr

Fuel gauge reading inaccurate. *tr

I have a 2007 chevy trailblazer with less than 50,000 miles, the fuel level sensor just went out. the estimate was nearly a thousand dollars.....this of course is not covered by extended warranty, which was included in the price of this vehicle when i purchased in feb of 2010. the low fuel light is on at all times. i estimate fuel mileage with every fill up. butt i am disabled, and running out of gas somewhere on the side of the road is not an option. i bought this vehicle thinking i would be safe driving it. i can't afford an expensive repair like this.i have owned gm all my life....very disappointed in gm... *tr

Fuel gauge always reads empty check engine light on obd code reports fuel sensor input high notified chevrolet customer assistance center 1/6/2011 reference service request number is [xxx] information redacted pursuant to the freedom of information act (foia), 5 u.s.c. 552(b)(6). *tr

2007 chevy trailblazer fuel gauge no longer works and constantly reads "empty." the trailblazer is my wife's sole transportation and puts risk to both her and my 3 year old daughter. in the instance that she runs out of gas due to her inability to know how much gas she has she is at risk of being stranded with my 3 year old daughter in the 100 degree texas heat. additionally, the risk of her being stranded away from home or on a highway puts her life in danger. the failure of the gas gauge and fuel detection unit occurred in january of 2011 and has not operated properly since. to fix the problem will cost $700. the fact that this is a known and common issue for these vehicles makes it obviously apparent that the fuel detection system is defective and the responsibility of chevy. it is in the best interest of chevy to issue a recall on the unit to maintain consumer loyalty to the chevy brand. otherwise, i am commiting to no longer purchase chevy or gm vehicles. *tt

The fuel level sensor installed in model year 2007 chevrolet trailblazer vehicles. the fuel tank level sensor is defective and could result in a subject vehicle running out of fuel, stall, and being rear ended by another vehicle. *tr

Gas gauge is irratic after filling up. i believe it is a faulty fuel level sensor. *tr

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. *tr

Fuel level gauge fluctuates from low fuel to accurate fuel level once actual gas level reaches approximately 1/2 tank. *tr

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. *tr

Fuel gauge stated i had enough fuel and i ran out of gas. it happened again just 2 months ago and i received a letter from gm telling me this might happen and that they will cover 50% of the cost. that's not good enough, i see complaints all over the internet. this needs to be a recall!!!! *tr

I have a 2007 chevrolet trail blazer that has a faulty fuel gauge. after a fill up the gauge reads full for approximately 20 miles and then reads empty and i get a chime and fuel warning light. i cannot rely on this equipment and fear running out of gas and causing an accident. *tr

Fuel gauge sensor malfunctioning. fuel gauge sensor malfunctioning and will read empty after filling the tank and cause the service engine and low fuel lights to illuminate. *tr

My 2007 trailblazer runs out of gas when gauge says full, have run out at 70 mph without notice on highway. have no idea when it is working or not will show full one minute then empty the next. repair is costly and have resulted to resetting trip meter, however if i forget or sit in traffic more than usual it is not accurate. i have run out of gas more times in the last 6 months than my whole life. very unsettling to be stranded not to mention unsafe to be in car not knowing when going to just stop. i have been told that it is the fuel sending unit. there are many many 2005 - 2007 trailblazer owners on numerous chat and complaint boards, why is there not a recall. i only have 65,000 miles this is ridiculous and not safe. thank you for your time. *tr

Tl*the contact owns a 2007 chevrolet trailblazer. upon starting the vehicle, the fuel gauge displayed a reading of empty. the contact refueled the vehicle but the gauge showed a full tank for a moment then dropped down to empty. the check engine light also illuminated on the instrument panel. the vehicle was not inspected or repaired. the failure and current mileages were 54,000.

I have a 2007 chevrolet trailblazer with a faulty gas gauge. the gauge will show how much fuel there is and then it will slowly go down to "e". i have to keep records of how much fuel that i put into the vehicle so that i do not run out of gas. this vehicle also has a faulty horn, where i need to turn the steering wheel for the horn to function. *tr

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. *tr

Fuel sender fails resulting in false report by fuel gauge as empty tank. incidences started in december 2010, 4 months after vehicle purchase, approximately 17,800 miles driven on vehicle, 5,000 by second owner. endangers driver by possibility of becoming stranded by running out of gas. repair, not covered by manufacturer, is prohibitively expensive, $500+, due to possible need to replace more than just sensor. incidents occur daily, as gauge sometimes resets on start up, then fails while driving, and sometimes immediately after start up. well documented defect of fuel system online and by repair shops, claims of no responsibility of defect by chevrolet/gm. *tr

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.

My car quit reading out how much fuel i had. i had to write down on a piece of paper the miles on the car when i filled it up in order to keep track of when to put gas in again. with my husband being disabled this was not good. i took it to my dealership and they wanted closed to $100.00 just to tell what exactly was the problem then if it was what they thought it was it would be approximately another $600.00 to fix it. i took it to a reputable repair place it cost $0.00 to tell me the problem and it cost me $418.80 to fix it. the problem was the fuel sensor was not registering the amount of gas i had. they had to take the gas tank apart and replace that plus the fuel pump (as now these 2 items are built into 1). *tr

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!!! *tr

The fuel gauge does not read the proper level. even if i fill the tank the gauge reads empty. previously when the tank would reach half full the gauge would read accurately. however; each time i filled up that level where the gauge would begin to work would decrease, and now it does not work at all. when there is approximately 1/8th of a tank left the gauge will read erratically, sometimes saying 1/4 full or empty. also, this fuel level sensor has triggered the check engine light to register on the dash, when diagnosed by the dealer they told me it was the fuel level sensor triggering the code and not an issue with the truck emissions. *tr

One day i was driving my trailblazer after i filled it up and a few miles down the road the gas gaugue went to empty.it does everytime time i fill up it will got to full then goes to epmty right down the road. been doing since november 0f 2010 (88,000) and as of march 2011 (94,000) its still doing it. i have to calculate my gas milage. i called cox the dealership and they wont fix it for free there is no recall on this and there should be. there is hundreds of complaints about this. i was driving down the highway once in the fast lane with my 2 year old son and i ran out of gas and almost got hit by 2 cars behind me. i got stranded for 2 1/2 hours till i got someone to bring me gas. this needs to be recalled!!!!!!!!!!!!!!!!!!! *tr

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!!!!!! *tr

The fuel sensor on my 2007 chevy trailblazer has failed. the sensor would function when the vehicle was refueled. however, the dashboard gauge would quickly drop to "fuel level low." for the past few months, the sensor has failed completely and the fuel gauge always displays "fuel level low." . this is a very serious safety concern. unexpectedly running out of fuel and not being able to monitor fuel levels puts owners with the same problem in a unnecessary compromised safety situation. i now monitor the level of fuel in the vehicle with the trip odometer gauge. i know that i have to refuel at around 300 miles from fill up. *tr

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...

Fuel gauge does not register the correct amount of fuel in the gas tank.

My 2007 gm trail blazer's fuel gauge began to show an empty tank when i would fill it up, and then when i would drive for a while, it would register full. eventually the engine light started coming on and going off at random. i took the vehicle to a garage and was told it would cost approx. $800.00. i could not afford that, so i started inquiring about the fuel pump and fuel sending unit. eventually i found a web site where i could purchase the sending unit for approx. half the retail price. i ordered the sending unit, took the vehicle to a garage to have it repaired and have not had any other problems with either the gauge not registering properly or the engine light coming on. if this investigation becomes a recall, since i have already made the repairs, can i be reimbursed? i would appreciate your response when your decision is made. thank you. *tr

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!!! *tr

Tl*the contact owns a 2007 chevrolet trailblazer. when the contact started the vehicle, she noticed the fuel gauge displayed an inaccurate reading. the failure progressed and currently the fuel gauge was inoperable. in addition, the check engine warning indicator illuminated sporadically. the warning indicator remained illuminated until the engine was turned off. the vehicle was taken to an independent mechanic for diagnostic testing. the technician stated that the fuel tank sending unit needed to be replaced. the vehicle was not repaired. the manufacturer was not aware of the defect. the failure mileage was approximately 62,000. updated 06/17/11*lj updated 06/27/11

Fuel level sensor failing. *tr

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. *tr

Fuel level sensor doesn't register correct amount of fuel. stalled in traffic in middle lane of 6 lane highway. chevrolet has admitted problem with "some" vehicles. i feel this is more widespread than has been admitted. chevrolet should recall and replace at no cost to consumer. *tr

Fuel gage sending unit shows that the tank is empty when it is full. it will work normally between 3/4 and 1/2 full and then drop to empty and sound warning chimes as if it is out of fuel. this is a huge annoyance and it is very common. i know 4 individuals that own trail blazers and all of them have had or are having this same problem. when talking to the dealership about this problem they told me that it is the number one problem among trailblazers. *kb

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. *tr

Fuel gauge incorrect readings resulting in several 'out of gas' situations. this has happened on busy express ways, remote rural areas, etc. safety issues. vehicle also has random warning lights that seem to come and go at will.

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? *tr

Fuel gauge reads when tank is full but as fuel is used gauge will intermittently go to empty and alarm will sound. i cannot be sure how much fuel is ever in the tank. i must rely on the odometer readings to approximate the range remaining. i fear running out of gas and getting in an accident. *tr

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! *tr

Fuel gauge on my 2007 chevy trailblazer quit working suddenly at about 40k mile. gm denies any recall in order, but seems to be a common problem across the country when i research it on the internet. now they're giving me the run around about fixing it. *tr

Fuel gage registered empty after fill-up and has not worked since.

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. *tr
