11 Electrical System problem

Failure Date: 09/26/2015

I recently started having problems, one being my brake lights don't always work. I took it to a local chevy dealer and was told it all had to do with an electrical problem as is impossible to fix. Shouldn't my vehicle be recalled? I'm a safe driver and it's a bit upsetting knowing that I don't know if and when my break lights are working. Especially when I have small children with me. We recently moved, as my husband was following me, he was the one that noticed my brake lights weren't working.

12 Electrical System problem

Failure Date: 09/09/2015

The driver door module does not work when it rains. I took this to a dealer and after they tested it told me it needed to be replaced $500. For part plus labor that they could not quote. I checked on line to find out if gm had recall on these vehicles and found that they did 2004 - 2007 mine is a 2008 experiences the exact issues that the others had but gm can't help me because my VIN # is not listed. Why did gm not try to help me with this issue? when over 184,000 vehicles where recalled for this issue. What do I need to do to see if I can get help to replace this? I wouldn't ask but I feel its only right to replace it after all those vehicles where recalled and mine is doing the exact same thing. It happens every time it rains apparently it leaks in the door some how and it gets wet and want work it controls seat heat, all door locks and windows and driver window. I purchased this vehicle used in 2014 and it has done it every since I have owned it by the time it gets back to the dealer its working again. Usually a day or so and it will work. This time its not working.

16 Electrical System problem

Failure Date: 11/11/2014

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. 00 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.

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 cheverollet 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.

18 Electrical System problem

Failure Date: 05/10/2014

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.

20 Electrical System problem

Failure Date: 02/28/2014

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.

21 Electrical System problem

Failure Date: 02/10/2014

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 discription of the malibu recall). The dot reference for this 656599.

22 Electrical System problem

The failure mileage was 61,000 and the current mileage was 63,000.

23 Electrical System problem

Failure Date: 01/08/2014

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.

24 Electrical System problem

Failure Date: 12/30/2013

I had to replace the driver side window motor at about 30,000 miles and now the passenger side motor is acting up and will probably have to be replaced - I am currently at 38000 miles. Seeing so many other complaints, including vehicle door fires, this should be recalled.

25 Electrical System problem

Failure Date: 09/09/2013

Incident with my 2008 chevy Trailblazer incident reported on sept. 9 at 9:30pm which occurred as I was driving home from a cubscouts meeting, with my 2 sons in the vehicle. As I was driving home around 845pm home from our methodist church,which is located about . 3 mile from my house. The lights on the dashboard and the headlights were not working all of a sudden and I could smell something burning as I a driving. The time of the day was dusk and starting to get dark but a clear sunny day before this occurred. My oldest son, who is 9, said what is that smell and then my other son, who is 4 years old also said the same thing. I drove slowly down the hill as this occurred off the road and the red light near our subdivision entrance. I live in hixson TN. I also noticed there was black smoke coming from under the hood area near the fuse box area on the drivers side vehicle. I got home within 5 minutes of this happening and immediately pulled my car into my drive way and told both my boys to get out of the car. I pulled the hood release under the steering wheel and went to lift the hood and could see black smoke was coming from the fuse box area. I popped the end clips that keeps the fuse box in place and opened the fuse box. When I did this, there was a spark of flame and smoke that put itself out when I lifted the lid off the fuse box and you can see what happened(photo attached for you to see). You can see there is significant damage to many fuses that control the electronics in the vehicle. I have not driven this vehicle since this occurred as the person I talked to instructed me not to move the vehicle. I would hate to get legal counsel involved and the national safety and transportation commission involved and would hope chevy would like to get this resolved. Sincerely, caesar wood. ## VIN passed ## Chevrolet Trailblazer 2008 ##.

The corrosion that could result in a short in the circuit board. A power short in door lock and power window switches to function intermittently or become inoperative. The short cause overhearing, which could melt components of the door module, producing odor, smoke, or a fire. After review with my service provider this is same problem with the pass recall.

34 Electrical System problem

Failure Date: 01/02/2012

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.

35 Electrical System problem

Failure Date: 10/15/2010

I bought this vehicle back in September 2009. Ever since I bought the vehicle I have had problems with the traction control lights coming on for no apparent reason. This happens when its hot and cold, dry or wet. Just starting the engine makes then come on. I have been back to the dealer for 2 years now for the same problem and they tell me that they don't know why it is happening and can't fix it. My vehicle is now out of warranty and will never be fixed. ?.
