  • 22,000 miles
The problems started in 2006 and were very intermittent. There is an electrical issue with the instrument panel, lights, battery, and other unknown items. The dealer check the electrical system when it started, but could not find any problem. Sometimes, while driving at night the lights went off, and I would have to pull off the road, check any fuses and relays, and then they would come back on. The next electrical issue was with the speedometer, which on a trip across to Florida it would be erratic and indicate I was traveling over 120 miles an hour when my gps said I was driving at 65. After the warranty expired I have had issues with replacing multiple batteries which go dead every 4 or 5 days depending on usage. After the speedometer stopped working, each other instrument panel item worked on and off. This includes the gas tank gauge, the ammeter, the temperature gauge, tachometer, and the oil pressure gauge. They all worked on and off for the next 3 years, and now none of these very important instrument panel gauges have worked for over 2 years. I wonder if the electronics that effect the air bags would work if I ever have an accident. I have replaced many batteries, I still have to charge each one every 4 or 5 days or I cannot start the truck. I have checked online and there are thousands of Trailblazer, and their related GM vehicles with the same problems. I hear that a recall was issued for the GMC-Envoy which is the same related parts vehicle but there is not one for the Trailblazer? I am dealing with these issues and hoping for the recall that we all have been waiting for. Thank god I have a 97 Toyota Camry that runs well. I wish [xxx] would read this. I also have photos of the non-working instrument panel, and the 120mph speedometer. Information redacted pursuant to the Freedom Of Information Act (FOIA), 5 U.S.C. 552(B)(6).

I can start my vehicle and the gauges started sticking. I am constantly being shocked by the driver door. My gauges no longer work at all and have completely went haywire. I have no dash lights. My vehicle has just died in the middle of a busy street. I do not know how much fuel I have, how fast I am going. My cruise control either at times increases my speed or does not hold the speed. I have to use a gps device to know approximate speed. This vehicle needs to be recalled. I love my vehicle but it has tons of issues.

I bought this car about 4 years ago and it has been nothing but an elecitrical mess. First my head lights would go out once a month, then a couple times a month, then once a week. My brake lights started doing the same. Our famliy mechhanic couldn't figure it out, he just kept replacing them and sending the bad bulbs in for warranty. A couple times the pigtails and lamps had to be replaces. Also 3 seperate occasions both headlights went out at once while driving. And I had to drive home in the dark with no head lights on. I took it the Chevy dealership after the third time abd apparently my fuse box was melted and needed to be replaced. Spent over $1000 doing that and it worked okay for about a year. Then headlights started going out again and brake tlights as well. Not once a week, but still about once a month or every other month. Recently my drivers window stopped working and I couldn't control the master switch to lock my car or roll up my windows. The cluster panel in the door needed to be replaced. Also, had two sensors that needed to be replaced because my 4 wheel drive, parking brake, and crusie control would stop working all at once and the lights would be lit up on the dashboard. I wasnt' able to use any of them until the sensor was replaced. Also the power shorted out in my side mirros, so I can't adjust the mirrors with the control or they start tiliting back and forth like crazy on their own. I have to get out of the car and adjust them manually. GM needs to do a recall, this car is not safe and I will not be buying a GM car while I look for a new car soon.

The headlights will turn off while the vehicle is in motion for no apparent reason. This has been occuring for several years. You can switch to the high beams and the high beams will work. After about 10 to 15 minutes of driving, you can put the lights back to normal and they will operate on the low beams. It may be a month before this occurs again.

My complaint is that I contacted Chevy dealer and advised of so many issues I have had with my vehicle since the purchase mainly most recent is the driver signal light will not come on and it was recalled 2004 recall# turn signal 05V198000 in which they advised me that the campaign has expired and therefore mine cannot be replaced. I have already almost had 3 car crashes because the signal is not working. I do not understand why Chevrolet did not replace when it is clear this is life threatening regardless of when the recall was put into force.

While driving at night noticed no low beam head lights. Flipped to high beam and they worked. Called a friend who said to check the relay by switching the fan relay with low beam relay. That was problem. Purchased a new relay next day and installed it. 2 days later, no low beam lights again. Popped cover on relays to find a melted mess. Low beam relay had melted along with the 15 amp fuse adjacent to it as well as the fuse box. Upon further research on line, this seems to be an ongoing issue with this vehicle. I'm currently hunting down a used under hood fuse/relay box to replace this one with.

Back hatch and window will only open occasionally if I'm lucky. Tail lights went out once and I was able to get the hatch open to fix it. They are out again and I can't get the hatch to open now. I have been replacing head lamps about every 8 to 10 months. Head lights are now going off for no apparent reason while I'm driving at night. I can flip on the brights and then wait a few minutes and flip back to low beams, sometimes this works sometimes it doesn't. the dome lights will not come on and stay on after I turn it off. Half of the dash lights for the radio are out, sometimes they will come on if I tap them. The feature that lets you turn the vehicle off and the radio will continue to play and the windows will still roll down as long as you don't open the door, is not working. Both O2 sensors are out and have been for a long time. I purchased this SUV brand new from a Chevy dealer. I have paid it off and kept up all of the general maintenance on it. When I took it in to get these issues fixed I was told it would be over $2500 to fix and that did not include labor. This SUV is a lemon, if I was in a position to trade it in or buy a new one I would, and I would not be getting another Chevy. I have never been notified of any recalls. I only found out about the electrical recalls on the turn signals and tail lights because a friend had heard about them and suggested a website to check. I'm calling the dealer today to see if I can get these issues taken care of. Another reason I will not be buying Chevy again.

I was driving down the freeway when I noticed my headlights went dark. All the other electrical components worked well (radio and stuff) and the lights came back on about 10 seconds later. The incident has happened a few times, but I can't figure out what is causing it. It's happened on the highway, the street, my driveway when I pull in... usually it lasts about 20 seconds and then the lights come back on. The high beams still seem to work, though.

There are a few things. And I just would like to know if there is a recall or possible recall issue at hand. The first thing that happened was the RPM gaudge. It will stick at 3000rpm or higher. But the engine is not over reving and the needle still moves up and down as if it would when reading correctly. But doesn't drop below the 3000rpm. Then it randomly resets and works correctly then will again randomly stick at 3000 empty or higher. The next thing that happens is the battery light will randomly flicker. Not all the time just at random. I had the battery tested and its holding a charge just fine. The weird thing next was I killed the power. No key in at all and it still flickered on my dashboard. Then stopped the next day. Another thing I was driving home 1 night from work. Turned my blinkers on to turn onto my road and my interior lights slowly come on and slowly turn back off. My head light wire on the drivers side burnt out about a yr ago which I replaced. Now I'm having issues with the drivers side. The bulb for my low beam is not blown. If U hit it comes back on. My drivers side speaker has not worked since I purchased my Trailblazer. And it will randomly work. This is recent. I really think there is an electrical problem. And my consent is a fire. Ive had it just under 2 yrs. And I'm only the 2nd owner and it had 34000 miles on it when I bought it in June of 2011.
