problem #102

May 192011

Trailblazer EXT 6-cyl

  • 90,000 miles


I was driving the truck and the fuel gauge was reading that there was gas in the tank. The vehicle died causing loss of power steering and power brakes. I was able to pull the truck to the side of the road with great effort. Had my wife or teenage daughter been driving the outcome might had been very different.after filling the gas tank the gauge went to E and never worked properly afterwards.

I was on a trip when I had stopped to fuel up my tank because it wad close to empty so once I fueled it up to full and turned my car back on for a second it showed full tank then just strolled to empty and after fee minutes went back to full. Couple days later the gauge just started going crazy and showing all kinds of levels of the fuel tank. Now it only stays on empty with the yellow light on. But before this all happened my oil pressure sensor stopped working. Its frustrating and I've been left without gas on middle of road a few times.

We have had this vehicle in the Chevrolet dealer shop several times over the past few years. Twice it was sent with the engine light on and came back to us with the same light still on. As a matter of fact, the last issue that was repaired had to be fixed two more times by my husband. The dealer repairman told my husband what to do in case it happened again. $800 later, it has happened twice. Also, the last time it came back from the dealer, the gas gauge had stopped working. I have been tracking miles to keep from running out of gas; however, I have still run out of gas five times! as a busy mom, keeping up with gallons and mileage becomes too much of a hassle. I'm driving (stop and go) 300+ miles a week. We haven't taken it back to the dealer because our income has suffered a loss over the past six months; therefore, we have been dealing with the problem. This is obviously a problem with a lot of 2006 trailblazers. I am asking for help because I'm tired of running out of gas.

In summer of 2011 I had the first occurrence of the fuel gauge incorrectly showing the fuel level. This went on for several weeks and then went back to normal for a few months. As of January of this year, I have the issue again, only this time the fuel gauge is down completely and showing empty 90% of the time. I have contacted GM and they are aware of the issue and offer 50% discount on repair. This should be a recall as this is a serious issue and obviously affecting a very large number of owners of this model of Chevrolet.

The fuel gauge stopped working and we were told to take it to our local Chevy. Dealer, where we were told that Chevy would fix this problem by paying half the cost to repair the problem, this is such a rip off, there problem yet we have to pay half to fix it, not right. I have gone to many web sites and this is a verycommon problem with Chevy trailblazers, all years. They should be recalled and Chevy. Made to fix there problem for nothing.

Trailblazer EXT 6-cyl

  • 80,000 miles
I ran out of gas on expressway on way home from work while gauge showed 1/4 tank. This happened again months later with tank showing just under 1/4 tank. Gauge around the time of first incident started bouncing around off and on at any reading while SUV was running. It would go from empty to 1/2 a tank and bounce around back and forth eventually stopping at a random amount. The gauge would go to empty when it was full until it was driven enough that I was down to around 3/4 of a tank then it would give the correct reading until guessing around 1/4 of a tank when the incidents happened with me running out of gas. A few months later the gauge completely quit working and has yet to work since then. I started researching online about the gauge and found multiple incidents with same year and make and many people stating they paid over $700 to have repairs done and multiple people stating they had it fail again. Since reading those remarks I have yet to have it repaired and have had to keep track of my mileage so that I don't run out of fuel again.

The bearings on the alternator are wearing and need to be replaced, the vehicle only has 29,000 miles and according to my mechanic they should not be worn this early and should be replaced as soon as possible; this is definitely a safety issue and a faulty part that I should not have to pay to have replaced. The fuel level indicator has stopped working over 2.5 years ago. I did receive a letter saying that the part may wear out prematurely and they are willing to pay 50% of the replacement but if it wears out prematurely then the part is faulty and I should not have to pay to replace the part. The backup light panel is bad, I tried to replace the bulb but the problem lies with the panel, faulty part again.

Fuel sensor failure, does not read true fuel tank level. Generally when full reads empty then as tank decreases gauge may read correct.

  • 36,500 miles
I purchased a 2006 trailblazer in 2006. It ran great until about 36000 miles when the fuel gauge began acting up. At about 36500 mile, the gauge quit working and I took it to the dealer and was told it would be $800 to repair. I have to try to gauge how many miles I can get on a tank of gas. It has been like this for over a year and a half. I have run out of gas twice, once in the summer with two small children in the car and once in the winter. This is a very dangerous situation and needs to be addressed by GM. I understand they say they will discount the repair 50 %, but this is not something the consumer has control over. We can not cause the damage as it is inside the gas tank. We have 2 GM products and if it is not remedied they may be our last. Maybe it is time for someone to file a class action suit. And we might all end up with new vehicles. I would think the recall would be less expensive.

Went to get gas for my 2005 Chevy trailblazer. When I did I got back in the vehicle and started the car. The empty sensor for the gas dinged alerting me that I was almost out of gas and wouldn't go above the empty level. It now plays tricks ranging from full to empty at any given point it can be full 1 time then go to 1/4 full then back up to full in 1 trip to the store. It appears this is a common issue from research on the internet.

Trailblazer EXT 6-cyl

  • 52,000 miles
The fuel level sensor went out and said there was no gas in the car when there was when it was still pretty new. Sometime during the trip, it would say it was full when previously it said it was near empty. Unfortunately for me I was traveling on the interstate and I had no idea how much gas I had or how much to put in the car. I could have easily been stranded alone on the interstate and put in a very dangerous situation. I also could not renew my license tag without getting it repaired in the state of ga. I thought the $400 expense after having a new car for less than 2 years for an electrical issue was ridiculously unreliable quality.

Fuel gauge showed I was empty after filling up the car. The gauge now reads erratically and does not show the proper amount of fuel in the tank. My wife is the primary driver of this car and I fear that she will run out of gas due to the "failure" of the gauge. We are doing our best to drive by mileage but our mpg varies quite a bit depending on our driving situation. Just received a letter from GM advising they will pay 50% of repair costs. However, I feel that this safety related item failure should be covered entirely by GM via a recall. Anything you can do to help would be appreciated.

Gas gauge became very erratic. Finally didn't register at all. Check engine light came on while out of town. Took the car to a merlin automotive for repair. Spent hundreds of dollars and the light would not go off. Mass air flow meter, plugs, fuel rail, throttle position sensor, fuel injectors. They even called in a Chevy technician who could not figure it out. When I returned home I took it to my local repair shop where they dropped the tank and replaced the sending unit. Hundreds of dollars in expenses. Then the heating fan switch started smoking and had to be replaced as it had melted and nothing worked. Also, every door rusted through at the bottom including the rear hatch. Dealers' response:welcome to Wisconsin. I spent $700 to have the rust cleaned up.

At 30,000 miles the fuel gauge on my 206 trailblazer started giving wrong readings. It never has the correct amount on the gauge. It has caused me to run out of fuel on several occasions. I have been lucky to not cause an accident. As the mileage can change based on driving I have to just fill up every 200 mile to be safe. GM has told me this repair is not covered under any warranty and would cost about $1000 for them to replace the fuel sending unit.

Trailblazer EXT

  • 63,000 miles
Bought 2006 Chevy Trailblazer ext used from the dealer in 2009 for commute to and from work. Upon reaching 63,000 miles began to have problems with fuel gauge reading half full them empty even after just having filled up the tank at the station. As a result check engine light activated and when it came time to inspect the vehicle no one at the local dealerships were willing to drop the gas tank and fix the problem so I could pass inspection. Penna state emissions would not pass the vehicle until the fuel system was repaired, hence cannot pass inspection. I will no longer use the vehicle on long trips where I have to guess how much gas I have in the tank, or take it on busy highways like 95 or 83 near Washington close to where I live. Problem description seems to be consisent with this model year. While I was willing and able to pay for my repair the first time, it is not my responsibility to account for a shoddy product. GM has already attempted to contact me and cover 50% of the repair via mail. This is an insult to my intelligence and I should not have to fork over one red cent to get this fixed given the massive amount of complaints about the same problem on the same vehicle. Ignition switch also failed at 60,000 miles. Yet another item I am finding is a recurring problem with this model, make and year.
