CarComplaints.com Notes: The Trailblazer emerged from an "upscale trim line" of the Blazer, but there's nothing upscale about its transmission problems or its wonky, unpredictable headlights.

I was simply trying to clean my windshield with the wiper blades. When I flicked the switch the car shut off. I immediately got over and turned truck back on. A couple days later I was leaving out for work when I tried to start the car, it stalled and I heard a hissing noise. I couldn't get it to turn over or make any noise other than hissing. The speedometer started moving back and forth erotically. The radio and power windows works but the engine would not turn over. I had it towed to my repair man and he told me there was a electric problem and to call the GM dealership for further assistance. The truck will not start up. There is a short. It shuts off constantly while driving and sometimes I have to push it to avoid oncoming traffic. It won't sped up past 60 without troubling the transmission. While driving sometimes the speedometer doesn't work at all or it jumps, around without reading my correct speed. When I try turn signals it cuts off. When I turn my lights on and off it hisses. Something has to be done. Its my only means of transportation and I really need to find a solution.

I was coming to a stop light my brakes did not want to work, then they did. I stopped my vehicle, my lights in my dash went out within a few seconds smoke started to roll from under my hood and cover my windshield. I immediately got out of the vehicle, and called 911. The vehicle was not running at this time, it stopped running. A bystander stopped to assist, he looked from the passenger front tire view and stated he seen flames that appeared to be blue. He wanted to lift the hood but I advised him not to do so, due to my job training I knew oxygen promotes fire. We got away from the vehicle, saint albans fire arrived on scene, the flames were out by the time they arrived, the car continues to smoke. The vehicle was moved to a lot, the key was put in the ignition by the fire department the dash lights did not work even with just turning the battery on. Triple H towing, towed the vehicle to davis smith's auto body. Geico is my insurer, I had full coverage however they will not cover stating it was mechanical failure. I have no without a vehicle, and no insurance funds to replace the vehicle. I have read online this is a common problem with this vehicle, I just do not want anyone to get hurt in a vehicle fire. Thank you for your time.

I approached a stop light. As I stopped, the whole car shut down. I turned the ignition "off", put the car in "park", and turned the "ignition switch" to restart the vehicle. It did start. A couple days later the same thing happened. I took it to my dealer on Sept. 15 2008.they asked if I had a lot of stuff hanging on the key ring, I did not. They replaced the ignition switch. On Jan. 21, 2011, I was driving, and, after stopping, the car was running but would not engage (move). Had the car towed to dealership. They again replaced the ignition switch and another switch. On Feb. 11, 2011, I was at a "drive-up" window, my car just quit running. I had to push it off to the side and have it towed to the dealer. This time they again replaced the "ignition switch" along with a transfer case switch and a transfer case module. They said they had to replace all of them since there was no way to know for sure if it was still related to the "ignition switch". I feel all my issues were relate to the "ignition switch", and all repairs should have been paid by GM.they new they had an issue, or the dealer would not have asked about "excess weight hanging on the key fob".. I believe the "ignition switch issue" goes back farther, and affects even more models, than they are currently owning up to. I still have all paperwork pertaining to my repairs.

I was driving my '02 Chevy Trailblazer on the interstate. The vehicle slipped and fishtailed a bit and I pressed the brakes to bring the vehicle to a stop. When the vehicle came to a stop, I tried to accelerate forward, but it would not move. The vehicle had not turned off on its own. I manually shut off the engine and restarted the vehicle and proceeded to move onto the shoulder of the interstate. I then noticed smoke and a small flame coming from under the hood near the front passenger tire/wheelhouse. The flames got bigger and soon it spread to the entire engine. The flames started near the right passenger wheelhouse and moved to the left driver wheelhouse. In about 20 minutes the entire vehicle was engulfed in flames. I have no idea how or why a fire started. I looked at forums online and many vehicles like mine have caught on fire while driving.

My 02 Trailblazer I bought used 4 days after I bought it the right turn signal would flash quick if I hit the brake but would be normal without pushing break. Than my brake lights started flickering and stopped working except for the middle one. Now when I turn my right turn signal on my reverse lights come on left turn signal flickers almost all the taillights flicker when on. I did research and found a recall for that problem and was wondering if my vehicle is one that was recalled the number is- GM recall no. 04087.

GM ignition switch recall needs to be expanded. My mother purchased a 2002 Chevrolet Trailblazer new. Approximately 5,000 miles into ownership, the car would "drop" various electrical components while driving down the road. For instance, while driving, the engine would continue to run, but the wipers would stop working, HVAC would turn off, air bag and ABS warning lights would illuminate, etc. Dealer had no idea how to fix. Eventually they replaced the ignition switch and the problem was solved. To my knowledge, GM never issued a recall, but I'm sure the issue is not isolated. These switches were unreliable across several vehicle lines, please investigate gmt 360 platform well.

All Trailblazer Tahoe and Envoy have the problem when you disconnect the battery it causes theses actuators to slam open and shut breaking them. The dealership is telling me almost 2000 dollars to fix this safety issue. This is a safety issue because I live in Michigan and depend on the heat to unthaw my windshield. Considering this is a manufactures problem and any mechanic knows to disconnect the battery to work on the vehicle. So what is this crap? do I have to retain a lawyer for this issue if someone could please contact me at [xxx] my name is [xxx] I would like to resolve this issue with a recall. Heat in winter I would say is a safety issue that needs to be recalled. I will be persistent with this.

While driving I noticed a burning smell outside of my vehicle but assumed it was coming from the area around me not my car. When I got to my destination I noticed smoke coming from under the left side of the hood and above the drivers side tire. I raised my hood and noticed smoke coming from around my fuse box. I had the car towed and have been told by my mechanic my fuse box and wiring harness burned. He also stated there could be other damaged related to this fire. The mechanic also asked if I had problems out of my headlights because the problem seemed to have started with the headlights. I have researched this since being given this information and electrical problems seem have been a problem with Trailblazers. I found several instances on this site and also online related to electrical problems on the Trailblazers. Complaint #10487846 is identical to mine and its a shame nothing gets done about these mechanical failures until there is a tragedy.

When driving the check gauges light illuminated and the oil pressure gauge was at zero. This occurred when I slowed and then stopped at a traffic light after having driven for about 20 minutes (the vehicle sounded as if it were about to turn off so I pulled over and turned it off). When looking at the instrumentation panel I then noticed the check battery light is dimly illuminated (battery is 6 mo old) and various readings are off (rpg is registering low and one RPM indicator starts at 5 when the ignition is turned on). Various Trailblazer forums are indicating owners are experiencing the same problem. Two Chevrolet dealerships have indicated that it is likely an instrumentation cluster problem (and indicate they have guidance from GM to run 2 checks to determine if it is an instrumentation cluster problem). Two independent repair shops have identified it as an instrumentation cluster problem that they have seen on many 2002 Trailblazers. The repair costs range as high as $750. GM customer assistance can only state this is not a recalled repair (applies to later models but not 2002); therefore, it is the customer's responsibility. My GM file # is [xxx]. GM did ask that I pay $80 for the diagnostics, while also saying they would not pay for the repairs. Adding an additional $80 to costs or paying a dealership more money than an independent shop is not practical nor an added expense I should assume. Most amazing is that GM can give dealerships instructions on diagnosing this problem, dealerships are repairing a far amount of vehicles with this problem, independent repair shops are aware of this problem because of the many customers who patronize them, yet GM takes no responsibility for correcting this known problem..this is dangerous, the car can stall anywhere and lead to an accident without customers having any idea of the problem.
