Purchased this vehicle from a dealer. The next day the truck was dead. It has since had the battery replaced 3 times. The exhaust manifold cracked at 82,000. The number 4 position on the blower does not work. The stabiltrak lights come on for no reason and go off for no reason. With all of the complaints, something should be done.

Low beam lights went out. We replaced bulbs, they worked for a short time. Low beams went out two or three days later. Went to local garage, they replaced wire from battery to lights as they were not getting any power. Lights worked for two or three days. Trailblazer was in shop for a week, unable to find issue. Called Chevrolet dealership, at first they thought it was a 2007 which has a recall for the issue. Found it was a 2008, no recall. Found bad/burnt/exploded fuse labeled 15016745. Have found multiple other people with same issue online.

Trailblazer 4WD 6-cyl

  • 89,000 miles
While I was driving down the road, both curtain side air bags deployed at same time. There were no other cars on the road, so I was able to stop the vehicle without causing an accident. The airbag on the driver side pushed me over so hard that it broke my center console. My lower back still hurts, but I am hoping the pain will go away. My left ear is still ringing and has not returned to normal hearing yet caused from the exploding noise from the airbag deployment. Both of the front seat belts will not work and the dashboard has so many lights going off, I don't know if there are any other problems. The dealership that I purchased the vehicle from said the damages could run as much as $4000 which I do not have and my insurance doesn't cover this since there was no accident that caused this. The dealership service dept. Also said they have never heard of any vehicles doing this. After research, I see that this has happened alot.

My fan blower quit working on some settings (0-5 available, only 1,2, and 3 make fan work). I bought a new blower resistor to replace it, and when I tried to disconnect the old one, I discovered what appeared to be an electrical fire had fused the harness to the resistor. I was able to break the harness away from the resistor, but two of the connectors on the harness are blackened, and the harness is partially melted away. When I hooked up the new resistor, 1,2,3, and 5 work, but 4 is still not operational. I believe 4 is not operational due to charring or melted plastic preventing connection from being made to one or both of the two charred connectors. First date of problem is estimated to be winter 2012, though it may have been a year or two earlier. My replacement of the resistor was 18 Oct 2014.

While driving on a steep downhill curvy mountain pass, the key got jerked into the off position. Luckily I quickly restarted the engine. This is very dangerous on roads with a sharp incline and/or decline as one would need to be able to brake and steer the car into a safe area.

The ignition switch has been acting like the ones that are recalled with the 05 - 07 model years. Our vehicle when you turn the ignition on it acts like its dead, even with no key in ignition you can turn switch a little and the gear selector light comes on as well as the battery light, and we have had two dead batteries from this.

The electronic control module "fried" and caused the brakes to "fail" - specifically, the brake pedal needed to be pressed to the floor although it had little effect. This sounds very much like the failure seen in the recall #3: 2014 Chevrolet Malibu. The ECM failure also caused a short in the airbag sensor. (a repair was done on the brakes - but I am not sure it was needed except for the ECM problem based upon the description of the Malibu recall). The dot reference for this is: 656599.

problem #26

Trailblazer 8-cyl

  • 27,225 miles
On the 2008 Trailblazer, had two problems with the ignition switch. In April 2011 the tumbler mechanism portion of the ignition switch failed at approximately 27,225 miles and was replace under warranty. In May 2014 had difficulty starting the vehicle when the ignition switch was in the start position. Was able to start the vehicle and drive to the Chevrolet dealership. While waiting for the service technician, I moved the tilt steering wheel to a different position and the vehicle stopped running. This would have been an extremely dangerous situation under normal driving conditions. It was diagnosed that the electrical portion of the ignition switch had failed. The ignition switch was replaced. The approximate mileage was 71878.

  • 69,000 miles
Repeated issue. Smell of smoke/burning triggers dash warning signals. Same dash warning signals come on without smell of smoke/burning. Cycle repeats itself without pattern, and includes during 4 wheel use. Vehicle taken to multiple Chevrolet dealerships for service (Utah, North Carolina and Washington) with the dash warning lights on. Utah and nc claim unable to replicate event or identify problem, so listed as unknown without correction. GMC executive office interdiction resulted in replacement of stereo even though dash light indicate powertrain & electrical. Stereo broke 2 mos later. Gmeo and wa identified fuse issue related to 4 wheel drive, but unable to replicate smoke/burning before claiming issue resolved. Dash warning lights constantly come on and off indicating problem with powertrain/electrical. Gmeo closed case as resolved.

Trailblazer

  • 98,000 miles
I've noticed several times that my vehicle will turn on when I place the ignition key into the "on" position right before I turn the key all the way to start it. I'm not sure if it was due to the cold weather or not. Also, my engine light is always on and I had it tested which came back as an emissions control problem. Which could be the gas cap I haven't paid to fix yet.

Trailblazer 6-cyl

  • 90,000 miles
In the fall of 2012, I had to replace an ignition switch in my Trailblazer at approx. 90,000 miles. Then, in July of 2013, we were driving on interstate 95 in ct, heavy traffic, high speeds, and all of a sudden my car just died. I, fortunately, was in the right hand lane and was able to drift off the road. A ct trooper sat behind us for an hour while we waited for aaa. It was a Sunday. We were towed to a Chevrolet dealer in old saysbrook, essex ct. Had to spend the night in a hotel and that Monday, the dealer put in another ignition switch. My mileage was a little over 100,000. Have all the documentation. Have you looked into ignition switch failure in Trailblazers" is my car safe to drive" would appreciate a response.
