2021 Chevrolet Trailblazer complaints

We purchased this 2021 Chevrolet Trailblazer RS new from the dealership and we noticed on the second day of owership that the brakes were "squealing". The dealership initially inspected the vehicle asap and without having to go through the service department. However, the problem not only continued, it persists to this day. Additionally, we just purchased a used 2023 Chevrolet Trailblazer RS (with under 10,000 miles) and are experiencing the identical issues with the brakes squealing.

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 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.

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.

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.

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

"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.

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.

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.

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!

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.

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.

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.

The contact owns a 2021 Chevrolet Trailblazer. The contact stated that while outside the vehicle, the power liftgate opened and closed independently. The liftgate struck the driver on the head. The vehicle was taken to the local dealer but the vehicle was not diagnosed or repaired. The manufacturer was notified of the failure but no additional assistance was provided. The approximate failure mileage was 5. The contact stated that this issue happens a lot and at any time.

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

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.

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 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.

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.

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.

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.

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.

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.

The contact owns a 2021 Chevrolet Trailblazer. The contact stated that while driving at various speeds, the vehicle made an abnormal popping sound before the power steering and brakes failed. Additionally, the brake pedal became extremely sensitive while gently being depressed causing the vehicle to abruptly stop. The contact had to restart the vehicle to correct the failure. The failure was intermittent. The vehicle was taken to the dealer however, the dealer could not duplicate the failure. The vehicle was taken to another dealer, Frontier Motors Incorporated (31406 US-18, Winner, SD 57580) on numerous occasions and diagnosed with electrical system failure. The dealer reprogrammed the power steering angle sensor and rear differential clutch sensor; however, the failure recurred. The vehicle was not repaired and remained at the dealer. The manufacturer was made aware of the failure. A case was being processed by the Better Business Bureau under the Lemon Law and was awaiting final repair notice from the dealer. The failure mileage was 1,574.

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

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 contact owns a 2021 Chevrolet Trailblazer. The contact stated that while driving at an undisclosed speed, the AUTO-STOP was not functioning properly. Additionally, the doors would not unlock on two separate occasions. Additionally, the keyless ignition button would not turn off the vehicle until the contact applied pressure while pressing on the button. The contact also stated that the tire pressure sensor was faulty. The check engine warning light and reduced power message was displayed on the instrument panel. The vehicle was taken to the dealer on two separate occasions and the dealer informed the contact that the AUTO-STOP function was unprogrammed due to the weather however, the dealer was unable to duplicate the failure. The dealer reprogrammed the AUTO-STOP software and tire pressure sensor however, the failure recurred. The manufacturer was made aware of the failure and the contact was awaiting a callback. The failure mileage was approximately 5,000.

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.

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

On June 10, 2021 I was driving home at a speed of approx 65 miles an hour from the grocery store on Interstate 255 when all my side airbags suddenly exploded. My 2021 Chevy Trailblazer RS was 3 months old and had 3500 miles on the car. After exiting the vehicle, I found the rear passenger tire was flat. Upon changing the tire, we discovered that the wheel had split apart. There is no damage to the body or underneath the vehicle. There was no large potholes or debris anywhere in the area. Upon starting the investigation with GM regarding the incident, they reported that the air bags acted as they should and they would not take liability. When both myself and the service manager of the dealership questioned why the report had not one single mention of the tire/wheel which caused the deployment of the airbags in the entire investigative report, we were both told "the airbags acted as they should" and the decision was final. The service manager was in shock and has stated repeatedly that based on the facts gathered and condition of the tire/wheel, there was some sort of defect in the wheel which caused it to explode. There is absolutely no evidence to make him think that I hit anything or caused the incident. GM will not discuss the case any further and told me to turn it over to my insurance. The fact that they did not investigate the cause (the exploding of a wheel for no apparent reason) makes me believe they are trying to cover up a potential issue that could impact the safet

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.

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.

I WAS DRIVING MY BRAND NEW 2021 TRAILBLAZER (ONLY 160 MILES) AND STEPPED ON THE BRAKE TO STOP AT THE END OF A STREET. SUDDENLY, I GOT ALERTS THAT MY BRAKE SYSTEM HAD FAILED AND RIGHT AFTER THAT, ANOTHER ONE, SAYING THAT THE POWER STEERING NEEDED TO BE SERVICED. AT THAT POINT, IT REQUIRED MUCH MORE PRESSURE ON THE BRAKE TO STOP, AND THE BRAKES DIDN'T SEEM VERY RESPONSIVE. LATER I SHUT OFF THE ENGINE, AND WHEN I STARTED IT AGAIN, THE CHECK ENGINE LIGHT WAS STILL ON, BUT I THINK THE BRAKES WERE WORKING AGAIN. I'M NOT SURE BECAUSE I DIDN'T WANT TO DRIVE IT, JUST IN CASE.

STABILITRAK STABILITY CONTROL SERVICE AND SERVICE ANTILOCK BRAKING SYSYTEM 2 TIMES SINCE I HAVE OWNED IT FOR ABOUT 2 MONTHS

TWO TIMES I HAVE HEARD A LOUD POP NOISE COMING THROUGH MY STEREO SPEAKERS. I NOTICED IT WHEN APPLYING THE BRAKES. I WENT ON A TRAILBLAZER FORUM AND A FEW OTHERS HAD REPORTED THE SAME THING. I HEARD THE POP TODAY WHEN I WAS PULLING INTO A PARKING SPOT AND APPLYING THE BRAKES.

BREAKS SQUEAKING

THE BRAKES INCLUDING BRAKE ASSIST STOPPED WORKING. PRESSING THE BRAKE PEDAL DID LITTLE TO STOP THE VEHICLE. THERE WAS RECALL FOR THIS SAME ISSUE THAT WAS PREFORMED BY THE DEALERSHIP 3 WEEKS AGO.

THEIRS A DELAY ON BACKUP CAMERA.ALSO ON ANDROID PLAY IT SHUTS OF AND ON ON THE SCREEN.

WHEN PARKING OR ABOUT TO MOVE AND YOU PUT FOOT ON BRAKE AND GET INTO A GEAR A LOUD AUDIBLE POPPING NOISE COMES THROUGH THE STEREO SYSTEM. IT IS VERY LOUD AND NOT BASED ON HOW LOW OR HIGH THE VOLUME OF THE STEREO IS SET. THERE IS A THREAD ON TRAILBLAZERTALK.COM ABOUT IT NOW. HTTPS://WWW.TRAILBLAZERTALK.COM/THREADS/POPPING-NOISE-IN-RADIO-WHEN-BRAKES-APPLIED.244/#POST-1557

WHEN IT IS DARK OUTSIDE AND YOU PUT THE VEHICLE IN REVERSE, THE LIGHTS NEXT TO THE BACK UP CAMERA CAUSES THE SCREEN INSIDE THE CAR TO SHOW BRIGHT WHITE. THERE IS NO WAY TO SHUT THE SCREEN OFF WHEN IN REVERSE. I HAVE TURNED THE BRIGHTNESS ALL THE WAY DOWN BUT IT IS STILL VERY BRIGHT MAKING IT IMPOSSIBLE TO SEE YOUR SURROUNDINGS SAFELY. I HAVE ALMOST HIT A TREE AND DROVE INTO A DITCH TRYING TO REVERSE AT DARK. THIS IS VERY DANGEROUS AND NEEDS TO BE FIXED.
