general problems of the 2021 Chevrolet Trailblazer

The contact owns a 2021 Chevrolet Trailblazer. The contact stated that while driving approximately 70 mph, the brakes became inoperative. The message "brake failure - speed reduced to 53 mph – service required" was displayed on the instrument panel. The vehicle was taken to a dealer; however, the dealer stated that the vehicle could not be diagnosed because diagnostic tests were available only by appointment. The dealer informed the contact that the computer software needed to be reset to drive the vehicle back to the residence. The vehicle was not diagnosed or repaired. The manufacturer was notified of the failure and provided the contact information about a recall; however, the VIN was not under recall. The failure mileage was approximately 135,884.

When stopped at a red light & the light turns green & I accelerate, the vehicle does not move. It makes a loud noise and jumps. This happens way too many times. There’s also an issue with the brakes, when you press on them, you can hear something grinding, which should not be happening because I bought the car brand new. Also the brakes have always been super squeaky, which is very frustrating because they should not be with a brand new car once again. The engine light goes on and off randomly and doesn’t say anything.

While driving, a service warning came on that reads "service power steering" - when that came on, the brakes ceased to work properly and required significant force, causing a big delay in braking. It is not safe to drive due to the limited braking. This mirrors the recall situation for other 2021 Trailblazer models with the interrupted brake sensor.

There is a faulty sensor on this car that does not allow the car to be properly parked and gives the error message "shift to park" on the dashboard. You have to turn the car back on and mess with the shifter multiple times to get it to register that it is park. This usually takes about 10 attempts every time you need to park the car. There are other reports regarding this exact issue on this car that further validates that this issue is relevant and needs to be addressed through a recall.

The contact owns a 2021 Chevrolet Trailblazer. The contact stated that while driving approximately 40 mph, the vehicle stalled. During the failure, several unknown warning lights illuminated, and the vehicle was jump-started. The auto start/stop function was disabled for the vehicle to operate properly. The vehicle was inspected by an independent mechanic; however, the failure could not be duplicated. The contact replaced the battery, and the failure was almost resolved. Additionally, while depressing the brake pedal, the vehicle failed to stop as needed. The issue was not diagnosed or repaired. The contact stated that while starting the vehicle, the rpm was abnormally elevated, and the vehicle jerked abnormally while shifting gears. The manufacturer was not notified of the failure. The vehicle was not diagnosed or repaired. The approximate failure mileage was 75,000.

Getting error message for shift to park not found when vehicle is in park. Chevy already has a recall for this but my VIN is not one showing it is affected. Vehicle is at the dealer now for diagnosis and repair.

A loud popping noise heard through the radio when light pressure applied to brakes. Noise loud enough to scare the hell out of all the occupants in the car. Brakes squeaked when car was in reverse. Tried to slow down on wet pavement. Car started to veer to the right. Forward collision warning nor automatic emergency braking worked. Pushed brake all the way to the floor and the car did not slow. Rear ended another car. No airbags deployed. My passenger was okay. I got diagnosed with a concussion. Do not know if the occupants in the other car were injured.

I have brought my car into the dealership over the last few years at least 6 times for the same issues. Currently there are two codes coming up as permanent on my car which is for the evaporative emission system flow and brake booster hydraulics performance. I drive my child of three every day and the number of times my check engine light comes on and goes into reduced engine power is not okay nor safe.

What component or system failed or malfunctioned, and is it available for inspection upon request? - the shift lever/gear control malfunctions when trying to put the vehicle in park. The vehicle once the lever is in park on the dashboard it will say !place vehicle in park. When it is in park you can't open the doors or turn off the vehicle. You can try to jiggle the shift lever but it doesn't move out of park. How was your safety or the safety of others put at risk? - unable to get out of the vehicle, the system locks the doors. Has the problem been reproduced or confirmed by a dealer or independent service center? - it has occurred at the beginning of the year. No it hasn't been confirmed by a dealer or independent service center. Has the vehicle or component been inspected by the manufacturer, police, insurance representatives or others? - no were there any warning lamps, messages or other symptoms of the problem prior to the failure, and when did they first appear? - once you put the shift lever in park and try to turn off the car the warning lamp comes on and says place in park. But the shift lever is in park. You are unable to move the shift lever. I don't know the exact date it first started happening but I believe it was at the beginning of the year.

05/29/24 I took this vehicle to cronic Chevrolet in griffin, GA due to check engine light being on. Code detected purge pump it was still under warranty at that time only had 43,906 miles on had to get the purge pump replaced. Several weeks after getting it back I kept getting a shift to park message come up when trying to put it in park then started having trouble getting it to go into drive. I have had so many close calls from people almost bashing into me because my car will not go into drive and you constantly have to switch in and out of gears for it to finally go in. Its sucking the had right out due to it not shifting gears properly. The code reader detected transmission control module which I find to be faulty and understand there are serval recalls on this specific vehicle , when it started this issue it didn’t even have 50,000 miles on it!.

The brake pedal goes to the floor and does not want to stop. There is a brake failure meesage on the dash.

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.

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

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.

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.

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

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.

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.

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.

Stabilitrak stability control service and service antilock braking sysytem 2 times since I have owned it for about 2 months.

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.

Brakes required extreme pressure to stop the vehicle. Accident barely avoided during rush hour traffic on busy surface road.

Breaks squeaking.
