Body Problems of Chevrolet Trailblazer - part 1

I could turn off the engine after driving, but the key stays in the position between the engine being on and the car being off (for example when you can listen to music but your car isn’t running). The battery light came on after the issue started and so the car service place charged us to replace the battery, because they had to turn on and of the car a lot and the car had to continue to run. I took it to a car service place and they ran tests and called chevy test support to run diagnosis tests. They can’t figure it out. They think it might be the body control module. Not sure what that is. The car only has 31,000 miles on it and this is a safety issue because what if this happens and the steering wheel locks or it becomes a rolling hazard. This would affect the driver and others. There were no lights or errors indicating a problem before this happened.

Found standing water in spare tire well. Back seat constantly wet, growing mold. The whole back area is moldy, mold under driver seat. My back passenger door seal has mold and water. Seat belts in back, mold. I had to wear a mask just to drive to the store. The mold turning black the day I took it to a shop for a water test. It's been two days and I still haven't heard anything about the water test.

I first noticed an issue about a year ago when an electrical blaring noise was coming from my speakers followed by popping and crackling noises. I have taken my car into the dealership several times without resolution. Since then, I have noticed excessive humidity in the vehicle and recently found the trunk was flooded. I took the vehicle in to the dealership again, and they say the interior fabric is compromised now and the electrical sounds I was experiencing are coming from electrical damage inside the body. I have now read another review online from someone who had the exact same experience with this make and model. I believe this is a safety hazard to drivers who are unknowingly driving around for months in a vehicle that could be flooding and could cause severe damages like in my case. I have documents to support these claims, but I do not have electronic copies. If someone reaches out to me I can provide hard copies.

Frame rotting out - has rot holes - unsafe - remainder of truck is good but without a solid structure this truck is unsafe and useless. Many Trailblazer frames do not last and rot out from what I've been researching. Bad product gm.

The brakes I’ve had issues with them making noises since I purchased my car. The rubber around the wheel wells about 6 months after I purchased my car and the shift to park just started this month September 2023. I feel my car is a piece of crap that’s falling apart.

On this vehicle the manufacturer is using plastic exhaust brackets. This bracket broke while driving on interstate. This caused the entire exhaust system to drop.

Looking at pics below you will see the defective plastic part is gm part# 42708943.

The contact owns a 2005 Chevrolet Trailblazer. The contact stated while driving 50 mph with a fully loaded pull behind 6x12 u-haul trailer hitched to the vehicle on the highway, a tractor trailer drove by at 70 mph, and the wake turbulence from the tractor trailer caused the u-haul trailer to fishtail, the vehicle and trailer did a 180-degree skid, spun around, and then jackknifed; causing damages to the u-haul trailer and the vehicle. There were no injuries sustained. The contact was concerned about the safety of the design of the u-haul trailer. The contact stated that the u-hauler trailer was not designed with the proper wheel and axle configuration which caused the trailer to be unsafe while driving over bumps or depressions on the roadway. The contact stated that he was advised by the south carolina state patrol to file a collision report. The contact had not yet contacted u-haul to report the failure. The vehicle was still drivable and was driven to the residence. The vehicle was not yet repaired. The vehicle manufacturer was not notified of the failure.

I was driving on the freeway and my panoramic moonroof literally exploded from the inside out. It sounded like a gunshot almost. Then the glass shattered. I am glad that the screen was closed otherwise all the glass would have gotten in my car.

Rear frame rail rust through at control arm mount locations on both driver and passenger side. In addition frame from suspension mount forward approx 2feet rust through. Vehicle was kept washed and has no other rust issues except for frame. I’ve learned that this was an issue from 2003 to 2008 model years. This issue has been checked and verified thru a reputable garage.

I have had multiple issues with the car since I've purchased it. The brakes continuously make noise, and the automatic emergency braking does not work. The tire pressure sensors don't work, they have the wrong tire pressure for each tire, and the tires constantly over inflate. Also, my front bumper is coming off. I've taken it to the dealership for all of these things, the dealership said the brakes seem fine, the front bumper clips seem to have warn down for some reason, and that they reset my tire pressure. There was no permanent solution. They put a band aid on my problem and I still have all of these issues.

See attached complaint to general motors. I have additional documents where others have had the same problems with there similar year Trailblazers.

My family was driving home on the freeway when the complete third taillight cover blew off. It appears that the adhesive that attaches the rear spoiler to the glass of lift gate has loosened due to a manufacturer defect.

My speedometer stopped working my gas gaige stopped working and my odometer went out cant see the milelage and I dont know how much gas is in the take,and the speed is mot working. I remember a recall awhile ago if you had the problem they said and I didnt at that time I think it was 2011.

My son was in an accident in his 2006 Trailblazer. He was crossing a city street intersection when another vehicle struck his truck on the drivers side at an estimated 40+mph, the truck flipped and slid about 15-20 feet. None of the airbags deployed.

I've noticed that my front end was lower than usual. At first I thought my upper control arms were giving in. I took my car to replace the front tires and to also get a 4 wheel alignment. That is when I was told that the strut base that is welded onto the chassis was rotting off. The mechanic expressed that I was a very lucky guy because at any point in time during my commute, I could have been in a serious car accident that could have resulted in death since I mostly use this car on the highway to commute to work. I didn't think much of it until he actually showed me all the rotted parts and I was in deep shock once I saw what he was telling me. I'm thankful that the cars strut was leaning on the inner fender frame preventing it from completely falling to the ground. I asked the mechanic how something like this could have happen and he explained that since we live in an area where it snows, the salt that is applied on the roads gets trapped into the slotted holes of the chassis and deteriorates with time. It is unknown of the time of which the chassis had begun rotting.

Driving on freeway at a cruise control speed of 70 mph without any warning lights or malfunctions with the truck, white smoke was noted from behind the truck. Smoke immediately became worse and truck was pulled off on side of road. Smoke was noted coming from under front hood as well. Driver then saw flames coming up driver side window. Driver ran from vehicle and it was consumed in fire. The whole vehicle was a fire bomb and destroyed. No injury was sustained by driver as of next day except to say shock and emotional trauma. Driver side door switch for safety recall of possible fire was done and serviced on April 2015. Truck was in the shop the previous day for a tie rod repair, oil change, and tire rotation. Mechanic said the truck looked in good shape without any problems noted on the vehicle. I have pictures on my phone of a ball of fire that was the truck.

Electrical fire started in driver door while truck was parked and not running. It was a total loss.

Driver door does not close. We've had it in a few times for repair as the driver's door hinges were loose. I was told by my mechanic of 13 years that he will not be able to repair it again. The last repair did not hold long, just about a week. Then I brought it to our local chevy dealer for repair as the door would not close all the way and bounce around on bumps. I was told the chevy mechanic that they are not able to repair the door, that I can take it to the body shop. My parents were the original owners. Just through normal driving the door would loosen, and drop out of alignment. I have had the truck in for repairs a few times as well. I have heard from my mechanic and the chevy mechanic that this is not uncommon for this particular model and year.

"takata recall" was driving down the highway doing bout 70mph and I hear a nosie on the roof and then I saw my whole 3rd break light asmbley break off and fly into the air and almost hit the car in back of me this can cause a major accident if it fly's off and hit a car in back of you and I was doing research online and saw its a common problem with these SUV its a poor design and needs to be recalled before somebody dies.

While traveling westbound on 192 in osceola county between narcoossee road and nova road there were several barricades 4 to 5 inches in the traffic lane. I was in the left lane with the barricades over the yellow line on the left-hand side of the road. This took place at approximately 8:15 am while taking my children to schoo, during the morning time traffic. My vehicle struck a large round orange barricade on the left side of the vehicle. I attempted to maneuver and avoidance however I was traveling next to a semi and was unable to do so. As a result my vehicle now has a scratch on the left side. I then called dot to report the damages and to have the site investigated for future incidences. The company conducting the construction work is jr davis construction. There is not a pull off zone or a place I felt safe stopping to directly speak with an individual in charge. I travel this road several times a day and have never seen the barrel barricades in the road as they were this morning.

On Saturday, August 1, 2015 at approximately 8:55pm my mother was involved in a 1 car accident on baum rd located in tallahassee, FL. She was the only passenger determined to be in the vehicle at the time of the accident. According to the crash report, d1 (driver one) was traveling westbound on baum rd going the normal posted speed of 55mph, when she veered towards the center of the rd and suddenly turned right veering of the right shoulder of the rd and striking several trees on the drivers side and front end. D1 was wearing her seatbelt and managed to exit out the drivers side window before coming to her final resting place on the shoulder of the rd. When I went to retrieve my mothers things from her Trailblazer, I noticed that no air bags had deployed. And as fast as my mom was going and the type of impact & damage her SUV sustained, I would think and hope the airbags would deploy in this type of accident, thus preventing serious injury or death. My mom was not so lucky, and myself and my family have endured great pain from loosing her so suddenly.

Don't know why air bags did not deploy, don't know why steering wheel spin then locked up, thank god it was not worse! state trooper said it could have been worse from the way I landed.
