2021 Chevrolet Trailblazer Complaint Log

Shortly after purchase, one of the factory tires had a side bulge. The dealer indicated in their opinion, was from a pot hole. However when they checked the rim, it was not damaged. I had tire replaced. Then at 39K miles, all the the other tires were already getting worn out. I've NEVER had tires wear about pre-40K miles in all my life. At local belle tire, they told me that the Hankook tires that come with new cars are not the same quality as those you would buy at tire store. But I submitted a replacement claim to Hankook, as the belle tire rep suggested, but they would not honor anything. Simply said need tire insurance. I notice when buying the car new, the dealers offer extra (cost) tire insurance. Must be because the are lousy, compared to buying at a local tire store. Now at 42K I'm replacing tires already. New cars should come with same quality tires as you buy at tire stores. And I will tell everyone about poor quality of Hankook brand.

Reduced engine power, code P0014. Camshaft actuator oil control valve bolt stuck open. All the signs and symptoms per bulletin released by NHSTA to repair if not sold yet. Extremely hazardous when accelerating to get on highway and engine power reduces.

The radio screen is constantly going black or glitching, the music will silence, the back up camera will stop working. Carplay does not connect often, also glitches in and out when driving. There is little to no air or heat coming from the floor panel when feet option is pressed for climate. In order to feel heat or A/C have to be on face option.

Whenever I accelerate over 65 miles per hour the engine and transmission light comes on and the car goes into reduced engine speed. I get a message to service my engine I took it to the dealership, they could not figure out the problem because the engine light only stays on for a day or so and then goes out again. This issue has been happening more frequently over the last few weeks.

Very strong gas smells coming from under the hood. After driving a few miles, fumes enter the passenger compartment. Had to stop parking it in our garage for fear of a fire before I could get it into the dealer. I've been told it's a fuel leak associated with the fuel rail system. I'm 20 days past my warranty and only at 29,000 miles. It's a nearly $2000 fix. GM was aware of the problem in 2021 as there is a service bulletin for this item. I should have been notified in 2021 that there was a possible problem which could lead to a fire or explosion.

The car will all of a sudden make a loud popping noise through the radio. It is enough to scare someone while they are driving and have a wreck. The brakes are very touchy to the point of almost giving you whiplash

The contact owns a 2021 Chevrolet Trailblazer. The contact stated that during inclement weather, water accumulated inside all four door panels. The contact stated no warning light was illuminated. The vehicle was taken to the local dealer and the contact was informed that the failure was common in the year, make, and model vehicle. The vehicle was not repaired. The manufacturer had been informed of the failure. The failure mileage was 23,520.

The contact owns a 2021 Chevrolet Trailblazer. The contact stated while driving 65 MPH the contact struck a deer on the front passenger side causing minor damages to the vehicle. No one was injured. The contact was able to stop on the side of the road. The contact smelled a burning odor and noticed that smoke was coming from the floor of the vehicle on the front passenger side near the seat belt assembly. The contact and the passenger were able to exit the vehicle, but after exiting the vehicle burst out in flames. The fire department was able to extinguish the fire. A police report was filed. The vehicle was towed. The manufacturer was not notified of the failure. The failure mileage was 20,000.

My key gets stuck in the ignition almost every time I turn the car off. In order to get it unstuck I have to restart the car, put the car in drive or reverse, put the car back in park and then try to take the key out again. This has to be repeated sometimes as many as 10 times for it to finally release the key. I have read about many other people having this same problem and eventually the key not coming out at all and they've had to have it cut out. I have an appointment at a dealership for August 1st (the first available appointment) and my vehicle is just out of warranty so I'm told I have to pay to have this fixed. This is clearly a manufacturers defect and first starting happening before my vehicle was out of warranty, I just didn't realize that it would become a much bigger issue the longer it kept happening.

Brakes failed and myself and others were in harms way. To my knowledge the car was totaled as the air bags did deploy.

Wiper system failed. No function of front wipers. Issue occurred on freeway, in heavy rain conditions, with fast moving traffic surrounding. Visibility with the inability to clear the windshield was at a minimum or not possible. Required pulling over, could have easily caused collision with no forward vision. Vehicle is currently at a dealership for evaluation. Previously brought into dealership, “no problem found” reported by the dealership mechanics. Three separate occurrences of this issue. No other warnings or lights associated.

I was waiting at the traffic light and the car just shut off without any warning and it wouldn't start back up. After a few minutes a warning came on that said "battery low-start vehicle." When I tried to start the vehicle it still wouldn't start. Then all of the warnings lights were flashing on the dashboard the wipers were moving back and forth but the vehicle still wouldn't start then the car just shut down and and nothing would come on. This happened in the lane of traffic at the red light. With the hazard lights not working it was a dangerous situation. The police were called to be there with me until the tow truck came so no one would run into the vehicle. I feel that the fact that no warning light flashed before the car just shut off was very dangerous especially after it wouldn't start back up. I had just purchased this vehicle (used) December 2022. I am very frustrated because now I don't have a vehicle to get to work. I only purchased this vehicle because my KIA was stolen and totaled October 2022 and I needed transportation to get to work. The car is at a Chevy Dealership now so they can try to figure what's wrong with the vehicle.

When putting the vehicle in park I receive a messege saying "shift to park" this means the vehicle is not recognizing I put the vehicle in park. This is a safety issue my truck is not even off when this message pops up. GMc knows about this issue and their is not a recall on it. Dealer will not fix the issue becazue it actually has to say that messege when they are diagnosing the problem. It does it randomly but more frequent now. I call gmc the only thing they can tell me is record it when it does it as a paper trail I guess. They are saying the same thing the dealership is saying they can't diagnose the problem without the shift to park messege. Been having this problem when I hit 20,000 miles

The contact owns a 2021 Chevrolet Trailblazer. The contact stated that while operating the vehicle at night, while reversing the vehicle, the back-up camera image became extremely bright creating a visibility hazard for the driver. The contact stated that the display screen was too bright to see images at the rear of the vehicle. Additionally, while driving at an undisclosed speed, there was an extremely loud audible squealing sound inside the cabin of the vehicle. The contact stated that after a while, the vehicle ceased. The cause of the failure was not yet determined. The manufacturer and local dealer were not notified of the failure. The failure mileage was 32,000.

The contact owns a 2021 Chevrolet Trailblazer. The contact stated that while driving at various speeds, an abnormal fuel odor was coming from the vehicle, without warning. While in traffic, the contact started feeling dizzy and pulled over. The contact’s son who was following her vehicle, also stated that he could smell fuel upon approaching the vehicle. The following day, the vehicle was taken to a dealer where the mechanic discovered a crack in the fuel rail. Upon investigation, the contact discovered Service Bulletin: PIP5765, which she linked to the failure. The manufacturer was notified of the failure, and the contact was provided a case number. The vehicle was not repaired. The failure mileage was approximately 21,000.

Took to mechanic due to strong fuel smell coming from engine area. Mechanic said not safe to drive - fuel rail leaking and must be replaced - vehicle could catch fire or explode! I drive grandchildren in this vehicle and was shook up! Vehicle towed to GM dealer who said I was 3400 miles passed my warranty but they would start work on my $3k repair. I’m outraged that GM cares so little about this known issue from the GM bulletin PIP 5765 which was published 11/18/20. All this time they have known about faulty and dangerous part but only send recalls for minor issues like possible faulty tire jack.

While traveling down the road at approximatly 35-40 mph with my two minor children, the steering was not responding properly and the car kept attempting to veer to the right. I let off the gas to slow down since the brakes were also not seeming to respond well. Upon attempting to brake and execute a left hand turn, the car would not turn at all despite the steering wheel being as turned as far to the left as possible, the lights began flashing on the dashboard for "PowerSteering" ESC warning. We ended up going through the intersection without stopping and narrowly missed another car in intersection and went completely off the road into a snowbank. Fortunately we were not injured. We drove the vehicle back home (approximately one mile) by overpowering the steering and manually forcing the car to stay on the road. Throughout the lane assist kept attempting to autocorrect and drive us off the road. The car was damaged by the impact and the mechanic said that the tie rod is bent and has no idea what could have caused this to happen. I am somehow now responsible for the situation. I have asked what caused the power steering to fail, and Chevy claims that they have no record of any power steering issues (which research has shown to be untrue) and in order to determine IF it failed and/or why, they need to make the repair and then run additional tests to re-create the issue. This car only has 21,000 miles on it, and has never been in an accident before this.

Popping sound from passenger side front speakers when releasing the brake pedal after a stop. Vehicle in drive.

Front wipers spray only on one side, the working side changes, sometimes it only squirts on one side, sometimes it sprays over top the roof of the car, sometimes it doesn't work at all. Reservoir is full, rear window spray nozzles always work properly. I'm unable to wash away debris, in winter with snowy roads it can leave salty/muddy windows. Sap from the trees & pollen create poor visibility. No warning lights are on, never have been. This happened without incident.

The contact owns a 2021 Chevrolet Trailblazer. The contact stated that while stopped at stop light, the vehicle shut off with the check engine warning light illuminated. Due to the failure, the vehicle was towed to a dealer and the transmission was repaired. Despite the repair, the vehicle continued to shut off without warning. One day while driving 60 MPH, the vehicle shut off without warning, and the contact was stranded in the middle of the highway. The vehicle failed to restart after several attempts even with assistance from the Highway Patrol. Due to the failure, the vehicle was towed to the residence and remained at the residence unrepaired. The manufacturer was not notified of the failure. The failure mileage was unknown.

Shortly after purchasing my trailblazer in 2020 I noticed a glitch in the speakers where it would make a crackling noise (mainly when the car is off). it hasn’t been consistent when it happens, but since observing the issue I notice the issue happens most often when I close the trunk (by pressing the button on the trunk door.) no warning lights shows when this happens. Although this doesn’t seem to be a harmful safety issue, anything electrical can result to something more serious. I plan to bring this issue up at my next oil change at the dealership.

Someone pulled out in front of me going 45 mph and totaled my car when they smashed into the front drivers side of my vehicle. My airbags didn’t deploy and no warning notifications or emergency braking ever occurred. This is dangerous and was severe enough to total my vehicle. My airbags should have deployed. No warning lights or any other issues when it occurred. It was inspected by insurance and determined a total loss.

"Shortage in radio" according to Chevrolet's diagnostic. Caused black screen, no back up camera, no beeping when in reverse and coming close to another object, no sound when blinkers or hazard lights are on, no radio, no power to front charger, no ability to use front auxiliary cable. Initially a loud buzzing noise which could not be controlled by the volume dial. Problems began on or around October 7, 2022. Purchase was made September 2020. Vehicle is available for inspection upon request. Problem can be reproduced/is constant. Problem was reproduced by dealer. Vehicle was inspected by dealer. There were no other warning lamps.

The vehicle began to give the error Shift to Park when the vehicle was in park and after the power was shut off. Because of this I cannot safely turn off the vehicle because it cannot recognize it's in park and will run the battery down whenever I use the vehicle. This problem has been previously presented in other models manufactured by GM. I am taking the vehicle in for inspection at a local Chevrolet dealership on 9/24/22 at 8 am. This issue first started around the second week of September this year with one or two errors here and there. Now, it happens every time I drive the vehicle.

When I shift the gear from PARK to DRIVE & step on the GAS, the vehicle hesitates to DRIVE. I have to turn off my vehicle, play with the gear shift, then shift again to get it to move. The other day I put my vehicle in DRIVE and it rolled back and REVERSED. Nobody can figure out what’s wrong with my vehicle. The check engine light comes on then goes off. Nobody can get the problem to duplicate. A ticket to GMC was submitted and from them, my vehicle seems fine on paper. This is a safety hazard. I’ve taken my vehicle to a Chevy dealer and also to a GMC dealer multiple times.

3 times in the last year while we were driving the acceleration wen very high like from 50 to all of a sudden went up to about 80. I had to stand on the brake and try to pull over. Still accelerating I put it in park and shut it off. When you restart it it drive fine again. This has happened three times and the dealership says they can't find a problem. We are stuck driving a death trap. Please help. They wanna charge diagnosis everything I take it in. Then they say they can't find nothing. Now I am finding others that have had same issue and dealership says there is no problem. This has got to be destroying the engine reving at such high speeds.

Second time in dealership shop to get gas smell coming from engine. Vehicle still under warranty. Afraid of the vehicle catching fire on me. Took it into another repair shop and 2 technicians notice the strong gas odor and was afraid of working on it.

Rear back up camera view on display screen image is fuzzy or shorts out for a second then corrects to give proper image.

Driving vehicle and noticed smoke coming from front end. Pulled over and entire vehicle caught fire. No check engine light, no temp gauge changes. Just smoke and then fire.

Vehicle makes a loud popping noise while connected to Apple play with usb cord while slowing down and while just driving.

Started having issues where all the electronics on the car go blank/dead. So far when this has happened it has not caused the car to be inoperable but in the meantime I have found that the car is leaking (seriously leaking) under the entire drivers seat was soaked. I noticed a while back that it smelled like mildew in the car, I had it cleaned and put a damp rid pouch in there, that basically absorbed in 2 days, but never could find the water. This week I found the water...under the drivers seat. This car has been leaking for 2 years! Last night, I get in the car and plug in my phone to charge and get a message of LIQUID DETECTED Charging is not available because liquid has been detected in the lightning connector. Disconnect to allow the connector to dry. At the same time the phone was plugged in everything started to crackle and squeal through the radio and then no radio at all. There is no way all these components are not damaged. Meanwhile I have take it to a dealer for them to do a "water test", I have zero confidence that this water test will yield any positive results and I am without a vehicle . So I am trying to get this info out anywhere I can to see if other people had similar issues and what can be done. It can not be safe to drive a car that the electronics have water damage.

The brakes make squealing sound when coming to a stop. the dealer has acknowledged the problem and said there is nothing they can do about it and that the problem is normal. It is not normal for brakes to squeak every time the car stops.

Shift to park. Vehicle will not shut off. Also trying to start vehicle having to repeatedly push brakes down hard and push to start before finally starting. I bought this vehicle with 0 miles this has been an on going on and off problem since around 20000 miles have been put on.

I had a smell of gasoline inside and under hood of 2021 Trailblazer LT 1.3l. Took to Chevrolet dealer.Confirmed gas odor. Gas was leaking from fuel rail.Sevice manager said it was pouring out. Found out GM has Service bulliten for this PIP5765 that covers both Chevy Trailblazer with 1.3l and Buick Encore GX with 1.3l motors. This has been a scary situation considering gas fumes could have caught fire.

The brakes squeak and squeal at low vehicle speeds including when in reverse.

225/60R17 99H Bought trailblazer brand new from dealer March 2021. I've owned many cars, street cars, etc. I've never had a tire with 10K miles develop a bulge in the side. I took back to dealer as warranty book showed covered to 12K, but they said 'upon inspecting, it appears from a pothole'. That was strange to me, as we never hit anything or the rim does not have a mark or bent or anything.

When I put my car in Park, my car fails to detect it is in Park, leading to a persistent error message that tells me “Shift to Park”, inability to turn off the engine, and battery drain. I’ve had the car since Oct. 2020 and this car has been doing this since at least Oct. 2021.

The contact owns a 2021 Chevrolet Trailblazer. The contact received notification of NHTSA Campaign Number: 21V440000 (Equipment). The contact called a local dealer and was informed that the only resolution for the recall would be to remove the jack stand inside the vehicle. The contact was informed that the jack stand would not be replaced. The manufacturer was not made aware of the issue. The vehicle was not yet serviced under the recall. The contact had not experienced a failure. Parts distribution disconnect.

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.

The brakes squeal and squeak when in reverse and applying the brake when going forward at low speed. I have been told there is a GM service bulletin that says this is normal for the brakes to make this very loud noise. I have not seen this bulletin and have not been able to find the bulletin online. At any rate this is not normal for a car with 7600 miles to have brakes that squeal all the time. I have taken this to two different dealers and get the same answer but I do not believe it is proper to make a customer deal with this when they spend close to 30k on a car and you will not fix it because it does not cause a safety issue. Bumper-to-bumper warranty coverage should mean just that.

The ABS and stability control systems crash without warning. Randomly on a trip the check engine light randomly comes on without warning and immediately my break system stops being effective. I have to put full force on the brake pedal to start breaking the vehicle and coming to a stop becomes difficult. This puts my life as well as others at risk as I would not be able to break on time. The problem immediately goes away after turning the car off and turning it back on leading me to believe it’s simply a computer problem. The service provider Chevrolet has not reproduced or confirmed the issue to my knowledge. No warning lights come on prior to the issue nor does the check engine line persist after being turned off and on again.

Purchased my 2021 Chevy Trailblazer in August 2021 with less than 100 miles. After about 500 miles the Lane assist, forward collision assistant and the automatic breaking features all stopped working. Factory reset has been set several times with no fix. The buttons on the steering wheel do not do anything when pressed. I have been told by the dealership they will need to keep my car for at least 3 days to disassemble and trouble shoot the issue, however they do not have a rental to provide me in the mean time. I am now at around 10K miles because this is my daily driving and only vehicle. I am not comfortable that some of the safety features have stopped working and fear that any day something else could stop working that is more important to the functioning of the car.

Cutter Chevrolet in Honolulu had a recall on my vehicle for a jack unable to support the vehicle. I had the appointment to address the recall. Their solution was to remove the jack without a replacement. Now I no longer have a jack. It will now cost me to have someone else to change a wheel that I can do myself. I have a spare tire with no jack in my new vehicle

Was in the middle of a 3 car collision. After about 5 min engine started smoking and a fire started. Fire slowly escalated and fully engulfed the entire car.

Within 3 months of owning the vehicle I started to hear a crackling sound coming from the passenger speaker in the door. At first it was loud and I thought someone hit me. It did it several times and then stopped. It has happened about a dozen times since I have owned the vehicle. When I took it in for my oil change I told them and they could not replicate it so they didn't know what it was and didn't see anything. It actually just happened again yesterday so when I take it in again I will tell them about this. We thought maybe it was only when it rained but that is not the case, it just happens and I can't think of anything that is consistent when it does. It comes out loud and scares me every time. I just want this fixed, I have only owned my car for 1 year now and like everything but this.

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.

The contact owns a 2021 Chevrolet Trailblazer equipped with Continental tires, Tire Line: Pro Contact, Tire Size: 225/60/R17, DOT Number: 16YOF98YW. The contact stated that while his son was driving at an undisclosed speed, the tire pressure warning light was illuminated then the front passenger side tire had a blowout. The contact's son pulled over on the side of the road and contacted a tow truck company for assistance. The tow truck driver replaced the tire with the spare tire. The dealer was made aware of the failure but informed the contact that there was no defect with the tire. The manufacturer was not made aware of the failure. The failure mileage was 2,100.

The contact owns a 2021 Chevrolet Trailblazer. The contact received notification of NHTSA Campaign Number: 21V440000 (Equipment) however, the part to the recall repair was unavailable. The contact took the vehicle to the local dealer and it was confirmed that the part was not available. The contact stated that the manufacturer had exceeded a reasonable amount of time for the recall repair. The manufacturer was made aware of the issue. The contact had not experienced a failure. Parts distribution disconnect.

I have had the 2021 Chevy Trailblazer since May 2021, it has been 15 months, not even a year and a half off the lot and i have had wayyyy too many problems. I have has service the stabilitrak stability control system, service the antilock breaking system multiple times within the first 8-10 months. I had to get a part replaced due to that. The dealership had my vehicle literally for a month after i bought it, had an open tak report through Gm due to my engine light coming on. Gm did not know why it was happening. Had 2 service engine and transmission system alerts. I have had a fuel injector and line replaced as well within the first 6 months. I have had to get the system updated 2 times also. Now August 2022 im having service battery, or starter. Have had my vehicle shut off on me at an intersection then come back on two different times. My breaks have been squealing ever since i got this vehicle. Dealership confirms everything is in good standing. I have not had a vehicle where breaks squeal when i am coming to a stop or backing out of my driveway constantly. Dealership keeps saying oh its just probably dust or dirt, spray them out and it should stop. But, it has not for about a year now! Unbelievable! I am going it to trade this vehicle in. This is wayyy too much to be dealing with when you pay $30 grand on a vehicle!

Brakes squeal when in drive. Any amount of pressure on the brakes the car shakes and a loud squeal begins. Bought the car new in May and this issue started in June. Have taken the car to the dealership since June to try and figure out the issue. Dealership states that rotors and brake pads are in perfect condition, thus the issue being the actual brake component. Dealership will not fix despite car being under warranty because there is no bulletin out for car model. I am very concerned for my safety and the safety of others when driving, especially since the dealership knows their is an issue and will not fix it.
