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.

On August 2014, general motor decided that a defect which relates driver's door was not working properly it was to be replaced a safety related defect corrosion that could result in a short in the circuit board causing the power door lock's and window switches to function intermittently or stop working in November of 2014 at the rochester, mn dealer was to install a new door module at no charge to me the Chevrolet dealer rochester, said they performed the service that November 2014 but as of today the power door 's lock and window switches are doing just what the recall said after the service was performed should not do so on July 2015 I retune to the dealer and told them about the lock and window switches not working and was told by the dealer I need to pay $130 dollars or more to have them fix the problem I told the rochester, dealer it was on a recall to be fix at a no charge to myself and was told they did fix the problem back in 2014 now the $130 is to see why the problem is back !!

I bought my Trailblazer (which I love) in the spring of 2012. A few months after purchasing the vehicle I came to learn that the horn no longer worked. I know the horn worked when I purchased the car because I checked it. I brought it in to a well renowned repair shop and they told me that their findings after looking it up was that there is a slight glitch with the horn and that, like other forms had stated, the more you use it the better chance of getting it to work. The mechanic said that he was reading that other people were having the same problem and that the horns on these Trailblazers needed to be massaged a little in the corner and the would work again. He said they got it working. I have yet to be able to get any noise out of my horn at all. This concerns me because of the safety issues that can arise with the lack of a horn to get someone else's attention if need be.
