Since the purchase my TB engine will stop when ac and heater is on on stop light, that it was delaying while driving. It got worse after "warranty was out, I believe in July 2007.no one can find the cause, but thinking its all system faulty., engine, electronics, fans. Could I afford a new car, I would not keep this car, as now I know it was the worse year making of all. Now I only pray to stay alive while driving and not get into some beyond my control but faulty GM model makers

When you turn the heat or air on high the red wire on the blower motor resistor gets hot and melts and I have 2 little girls that ride in this vehicle. This isn't normal

Gauges on the instrument panel stopped working. There are currently 3 gauges not working on my instrument panel including the speedometer and the gas gauge. This is extremely dangerous not knowing when your gas tank is empty or how fast your going. The gauges do not work whether I am driving or stopped.

Nov.2013 was the frist time we had a proplem, right after that the oil gauge was not working. On an off we have noticed other type of problem that seem to be electrical. For the last year \year an half my gas is all over the place, always stopping to get gas as not to give out. Also, my gear and mileage gauge does not work. Now have no idea when to change the oil or rotate tires

GM ignition switch problems/recall. On 07/18/2014 I took my 2005 Chevrolet Trailblazer (32,262 mi.) in for service to fix/replace parts: Faulty ignition switch. Today, 06/02/2017, my Trailblazer (35,193 mi.) is still having the same problem. A faulty ignition switch which is causing ABS and parking brakes lights to come on and stay on, the blower for air/vent will not work and since these parts are all connected electrically, I once again have to replace the faulty ignition switch. I was never reimbursed for the first recall. Please look into this matter. I would hate to get rid of a perfectly good vehicle, that has held up all of this time, I only have 35,200 miles on this 2005 Chevrolet Trailblazer. Will the ignition switch keep failing on this vehicle? thank you.

When driving vehicle both left and right low beam headlights go out. The first time it happened was when I was driving long distance in the dark. Had to drive with my high beams on for the rest of the trip. There is no specific time frame, but generally it happens anywhere from 10- 30 minutes of driving. I suspect it is heat related. I have changed the headlight relay #46, bit it only fixed the problem for a week. Again the lights will go out after driving several minutes. I noticed there is a recall for a similar issue on the 2006 Chevy Trailblazer. Could this be the same problem with my vehicle. There are also multiple forums explaining the same exact issue with early 2000 model Trailblazers. This issue happened approx 6 months ago. Last week we ran into another problem. Our ABS light comes on periodically. Like the headlights going out, the ABS light comes on after driving the vehicle for a certain amount of time anywhere from 10 minutes to 30 minutes. Again, I feel it electrical components/wiring is overheating and causing these issues. I feel there should be a safety recall for this this issue as it is affecting hundreds of customers usa wide.

The driver's door master power window switch module got hot & started smoking. Removing and looking at it showed that it caught on fire. It looks like it started somewhere on the circuit board. It seems identical to the problem listed on the 2006 Chevy Trailblazers. (NHTSA campaign number: 15V599000) it happened in 2015. I've just been holding onto the part because I didn't know what to do with it & the local dealer wasn't any help.

I bought this car used in 2009. It had about 60000 miles on it. 1) the first problem I had with it was a burnout of the hac blower plug, that part of the wiring harness had to be cut out and replaced wth a completely new plug( both halves) and rewired in for a cost of 125.oo and 3 hours of labour. I looked this up on the internet very common problem 2) rider side door control panel stopped working with strong odor of burnt plastic. Again looked up and found there was a recall, but only 2006 vehicles 3)brakes burn out of rotors only on rightside- left side rotors were fine, brake job with replacement of 2 left rotors I front piston amd all 8 pads $650. Failure occurred while driving on city street 4) failure of ignition switch with erratic electrical function of running lights, radio and dashboard instrumentation. Happened on the road early twilight very dangerous had to get a local toll for $75 all of these failures have made me very wary of driving this vehicle. They occurred at various times over last 4year some have been repaired as noted above. Presently waiting for igniton system repair.

Fuel gauge always shows empty, not working. No way to know how much gas is in the car. Oil gauge not working.

- Boston, MA, USA

The low beam headlamps fail simultaneously. This occurs while driving at night. I have replaced the hdm solid state relay twice, but after a time. 6 months to a year, the failure occurs again. Once the hdm module became to hot to touch upon failing. This last time, the third, the lights may come on again after some time has passed. It is as if the module is short circuiting or overheating leading to a short circuit.

The low fuel gauge indicator remains on even after I fill my fuel tank. The indicator never goes off at anytime.

Since 2011 I've been having wrong reading of gas levels causing my vehicle to shutoff. Plus my passager air bag displays on when no one is sitting in seat and when someone is sitting in passager seat it occasionally flicker on and off. However I have not had a incident just yet but I'm very concerned and don't feel safe driving with my kids in this vehicle.

- Washington, DC, USA

As of 2011 (while driving on freeways in multiple occasions) I've been having electrical issues such as my fuel level gage would read full and vehicle would shut off cause no gas in tank, air bags sensor would show it on when no one is sitting in the passenger seat, and there are some electrical issues on driver seat controls not working, dash board gages not showing readings while vehicle is in motion (rmp, speedometer, oil, gas).

- Fontana, CA, USA

The speedometer will not work properly. It will be stuck and then it will not display the correct speed while driving. This has been a problem with this car for 2 years. Also the fan control switch stops working at the same rate. Some days it works and some days it won't.
