car   Electrical System problem 8
Failure Date: 03/11/2015

While traveling about 15mph through a boat yard with my heater on high (5) I smelled a hot metallic odor, but thought it was just from some welding be done on a steel boat. Then my heater quit. I turned it down to 3 or 4 and it ran a little longer and quit completely. When I got home I checked on a Trailblazer website to find information and found that the blower resistor speed control unit was a common cause of this type failure. Upon removing this resistor pack I found the plastic plug connection on it had gotten so hot that it melted and fused the plug in the socket. When I did finally get it apart I found that one of the connector pins had burned completely off. Insulation on three or four wires had also been burned. Luckily there had been no major fire.

car   Electrical System problem 11
Failure Date: 01/01/2015

Multiple times while driving the headlights will malfunction and turn on and off, at random driving speeds under many different conditions. I continued to drive the Trailblazer even after this occurred. Just not as often. If the heater was on while driving and the headlights would short the heater would stop and then turn back on. The fan turns on at random, first it turns on when driving at random times. The fan will turn on at random times with a higher speed and sound. I have had the inspection completed multiple times with a mechanic re-assuring the issue although it has been happening frequently. The check engine light is on all the time due to computer error and is a $500. 00 fix. This has all happened and been reported within the first year I bought the vehicle from kendal motors in lewiston idaho. I find that the amount of work to fix this vehicle is overwhelming and to see that this vehicle was under 100. 000 miles is financially distressing. I have already had the fuel pump portion removed and fixed twice, I had to purchase a locking cap. The stereo repeatedly jams with new cd's even.

Failure Date: 11/07/2014

I noticed my battery guage quit. Then after starting my truck a few different times, the gas guage read differently. Then my speedometer wduld stick on 100 when I was doing approximatly 60. Then the speedometer would not work at all. There needs to be a recall on it. My friend has a 2005 also and her cluster pannel went out too. Its a 400. 00 repair. This has happened to quite a few 2005 Chevrolet Trailblazers from what ive read online. Come on general motors. You need to recall these models.

car   Electrical System problem 15
Failure Date: 10/07/2014

For approximately 6 months my 2005 Chevrolet Trailblazer's speedometer was intermittently showing that I was going from 100 to 120 mph. It didn't matter what speed I was actually going or even if I was sitting still. I called the Chevrolet hotline because I noticed other owners having the same problem. They were basically not helpful. As many complaints that there are about this defect, I cannot believe the NHTSA has not stepped in. It is now happening all the time as it is approaching 74,000 miles which seems to be the mileage when everyone is stating they are having the most trouble.

car   Electrical System problem 16
Failure Date: 10/01/2014

Since October 2014 the speedometer would randomly start up at different initial points. Some days it would start at 60 mph, 10mph and recently it starts up at 110mph. When the vehicle is in motion the needle would move when accelerating but the readings are completely inaccurate. I have read various online blogs of this same incident happening to numerous chevy Trailblazers in general. Gm does not have this problem as a recall therefore I would formally like to make a complaint. Thank you for your time.

car   Electrical System problem 17
Failure Date: 08/29/2014

I bought this car at the end of March of this year with under 100,000 miles. The first thing to go was the gas gauge, about 2 months after I bought the trail blazer the needle went south. It actually hovers around 6 0 ' clock. Then a couple nights ago driving home I had the cruise control on, I took it with the hand button and looked down and the needle never moved, it was stuck at 65. It's been 3 days and the needle has moved but the wrong way, to the right going up 75, 80, 90, then back down to 65 and staying there. I have looked into replacing the gas gauge and I was told the entire dash would have to be done at a price of 1200. 00, I should not have to do this, Chevrolet should be held responsible.

Failure Date: 06/10/2014

When I fill up with gas my gas gauge reads 0. After driving 40 - 80 mi. It slowly comes back, but reads incorrectly for a few miles. By the time its nearing 1/4 to 1/2 tank is seems ok. I really think its only a matter of time before it quits altogether. I don't trust and use my odometer to estimate my gas level.

Driver's side passenger door left rear door latch on 2002 Chevrolet Trailblazer LS is stuck. The door will not shut! I have read another complaint for the very same reason and a very similar situation to the ext and there is a recall on the ext but doesn't pertain to the LS. I can't shut my door because the latch won't connect. I opened the door and could not shut it after that because it wouldn't latch. We have looked everywhere and have not been able to locate the part at a reasonable price. I was in the process of selling it, but because of this faulty defect we cannot sell it. We have not been able to get it fixed. No one seems to have the part and we contacted dealerships and they looked up recalls but couldn't help us cause our VIN number isn't covered. What do we do now??.

The windows would roll up by themselves, one of my dogs almost got his head stuck in the back window, also seat heater would come on and switch from high to med. To low, then back to high. I had it repaired, cost was $413. 00 I'm hearing the same trouble has been reported with the 2006 - 2007 models and some have caught fire. Is the new part going to do the same? can I recover any of the cost?.
