36 Other Fuel System Tank Assembly problem

Failure Date: 07/01/2010

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.

37 Other Fuel System Tank Assembly problem

Failure Date: 05/01/2010

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.

The fuel guage on my 2007 Chevrolet Trailblazer is faulty. I have ran out of gas several times when the guage shows a quarter tank or less. No low fuel light,no gauge needle on empty,just a dangerous gauge that should be recalled by gm before someone runs out of gas on the freeway and gets ran over. My vehicle had 60000 miles on it when the problem started. After some investigation,I discovered I am not the only one with this problem.

While operating my 2007, Chevrolet Trailblazer , I notice that the vehicle was leaning on the right side ,I stopped the vehicle and after checking the tires I found no flats ,and no air missing, as I drove away I began to feel a wobble in the front tires , which led me to meyer Chevrolet , where he found that the shock absorbers where still good several weeks later the leaning and the wobble continued and I took it to my mechanic where he found that all the shocks where leaking and had worn out at 33000, miles , before replacing the shocks I called general motors to see if they can set up an appointment with another dealer which they stated that I should return it to the dealer I purchased it from . I then returned the vehicle again to meyer Chevrolet where again I was told that they where good and not bad , I continued to drive the vehicle and the tires where so bad that I decided to take it to my mechanic for an inspection of the front end which he found that the four shocks where bad the tires , and the alignment where bad , I then called Chevrolet to ask for there assistance in the costly repairs and they stated that because I had my repairs done elsewhere they could not help , so 1400 dollars later my car is running good again lets see how long before something else goes wrong . Last year while driving to virginia beach , I stopped to refuel and when I got in the car again the gauge had stopped working , the little yellow light came on and would not shut off giving me false gas readings that the tank was empty , when I arrived in virginia beach I called the dealers for an appointment and no one would repair it they said take it back to new york city for repairs . I then placed a call to on-star and they said unless you get stuck you will have no choice but to take it back to new york for repairs , we will send you a tow truck at that point and left me with a car that I didn't know whether there was gas inside or not . Gm get it together .

This Trailblazer was purchased as a demo from a local MD dealer. Around 36000 miles I noticed was fuel gauge was continually moving, it would go from a full tank to empty, for no reason. That problem lasted about 2 weeks, from then on my fuel gauge did not work at all, the gauge sits on empty, regardless of how much fuel is in the tank. Also the low fuel indicator rings constantly a random times. Also the check engine light goes on and off. I took my truck to a local dealer and they quoted a price of approx $600. 00 to fix. I have researched this problem, apparently it is a very common one.
