Print this page Notes: The 2002-2007 Chevrolet Trailblazer is known for many things, but perhaps it is most famous for its faulty fuel gauge.

This gauge flip-flops more than a politician during election season. Some report that the gauge says "empty" after a fill-up, while others report the gauge says "full" when they're running on fumes. Either way, there's one thing everyone seems to agree on: the darn thing is just wrong.

Following hundreds of complaints and a few accidents allegedly caused by the malfunction, the National Highway Traffic Safety Administration (NHTSA) opened an investigation into the issue in May 2011. Unfortunately for frustrated owners, no recall has been announced.

I purchased a used 2007 Chevrolet Trailblazer 15K in June 2008 form bob bell Chevrolet eastern ave. Baltimore, md. This vehicle was advertised and assured to be a GM certified vehicle which was reconditioned and 117 point inspected under GM certified used program. I don't believe that this vehicle underwent this inspection as the dealer represented because a week after purchasing the vehicle, I had brake failure and traction control malfunction that the dealer repaired and assured me that I would have no further problems, on top of that, the oil wasn't changed or air filter which was as black as the street when it was changed out. Now a year and a half later, I'm having noise in the steering column and was advised that a noise I was hearing in the front of the vehicle when I went over a bump was my struts that needed to be replaced when I took it back to the same dealer purchased and advised my vehicle which is now at 47K is out of warranty for the repairs needed and I was going to need to pay almost $2000. My problem is I haven't had this vehicle that long and my dad owns the same year and model vehicle with zero problems, I have never had a vehicle which was supposedly as good as new with these issues. The dealer hasn't gotten back to me and I feel like they are avoiding my problem which I believe was their fault and should be fixed because they represented themselves and this vehicle to me as such and that was under the condition of my purchase, can you offer me any help or advice"?"

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.
