Filed Feb 2, 2014 · Electrical, Fuel system · 110,000 miles · IA

Vehicle's headlamps will power surge, dim while driving periodically. Fuel sensor showed constant empty until repaired by the recall. Vehicle will occasionally surge forward revving on it's own at random times. The blower resistor pack has burnt up twice, the blower motor has been replaced as well as the melted wires.now the vehicle will not start. The power windows, locks, radio, dome lights, dash lights are inoperative and the vehicle will not attempt to turn over. Seems like this vehicle has had a lot of electrical issues.

My 2005 trailblazer has begun to have several problems and in speaking to other chevy owners the same problems have been found in other models and years of chevy trucks and suvs. I'm very disappointed to see that chevy chooses not to recall, which is why I'll never purchase another chevrolet. Beginning a few months ago my gauges began to be erratic. Starting with my speedometer sticking at zero and then later sticking at 60mph even while sitting still. Sometimes it works and sometimes it doesn't. Next while sitting at traffice lights or stops signs my engine began to surge forward without applying the gas. When the vehicle surges the RPM gauge also jumps up. I already replaced one transmission at 50k miles and now since passing 100k miles have begun to have rough shifting again in my vehicle. I do not drive my vehicle in a rough manner, speed, or haul a trailer, so there is no reason to be going through transmissions. Now my fuel gauge has stopped working and I'm having to track my mileage with my odometer. I've never seen a vehicle with so many problems and no help offered from the maker. * tr

Traffic was horrible bumper to bumper, I was driving and realized not to rush so I stood in the first lane, as I was driving bumper to bumper I always drive within one car lengths in case I get rear ended. As I am driving bumper to bumper all for a sudden next thing you know my car just suddenly accelerated at incredible speed I manage to swerve into the emergency lane to avoid causing a multiple car pileup my car died instantly I started it up again and it just wanted to take off as it did before I turned the car off thinking to myself my god what just happened and what is going on, I am trying to calm my 12 year old child because it was the most frightening thing I am my family ever went thru. I press the break and just relax for a second and started the car up and it was fine. However, my nerves were pretty much shaken, I had taken the car to jj auto shop in hayward who is ase certified he did a diagnostic on the vehicle he said he could not verify what I was saying, no error lights and the history was clean. He also mentioned the computer at times does not pick up a split of a second acceleration. He believes my story and said everything is done thru computer so there is no finding as of the moment. I was not sold on that but he also recommend I could change the body throttle @ 700.00 but he said I just dont want you to buy the part so you could just drive in the slow lane and if it happens again to shift the car into neutral and turn it off asap> my thing is since cars are computerize this should have why is it they could not verify my situation and also body throttle what he was looking at and what chevy thinks it was! So my complaint is for chevy did they overwrite software to overlook sudden acceleration? The only major issue I had had with my vehicle was when the speedometer went crazy as I was driving 110 but was really going 35mph

At low rpms the truck will lunge forward /reverse depending which gear you are in . This happens when it wants it is not a constant . It idles high and surges. First occurrence happened in feb dealer did nothing . Next occurrence it almost hit my daughters friend when she passed in front of me. Again dealer did nothing and finally the last occurrence it lunged into a tree. Again dealer and gm found nothing. I have documentation from the mitchell repair company that states that the year make of my truck this has happened . However gm denies this. This truck is not safe.
