Coolant control valve replacement after 5 years of purchasing the vehicle. Put at risk of over heating while driving, fan stays on after vehicle is turned off. Problem confirmed by 2 dealerships. Check engine light on for a long time, fan over working, staying on after the vehicle is off. The only warnings were the engine light coming on to get inspected and fan over running. 1st came up in December 2025 and it is now almost April 2026 costing me $1600 in repairs!! There are other Chevy models that this looks like it is being covered for but my vehicle is having this issue now and is not being covered?!?? Ever since i bought this vehicle brand new in 2021 it was labeled a lemon and have had nothing but issue after issue after issue!!
VEHICLE WAS TAKEN TO DEALERSHIP FEB 2026 FOR TURBO/WASTEGATE REPAIR (P0299). MARCH 22, 2026, VEHICLE STALLED AND SCREEN SAID TO SHIFT TO NEUTRAL AND PUSH TO START AGAIN. CAR WOULD CRANK BUT NOT START (SOUNDS LIKE THERE IS NO COMPRESSION). HAD VEHICHLE TOWED TWO MILES TO RESIDENCE AND CONNECTED TO OBDII SCANNER, WHICH SHOWED 6 NEW CODES (P0006, P228C, P0089, P0340, P0365, P0299).
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 on the highway, I heard a loud pop that made me flinch and swerve. After parking I noticed the glass in the sunroof had exploded upward like a volcano, leaving a large hole. Fortunately the shade was closed, or glass would have come into the car while I was driving.
My transmission is defective and past 60,000 miles but only a little. I had a diagnosis and it needs replacing like many of these trailblazers in the ongoing lawsuit. I cannot pay for it and it should not be broken!
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.
I was driving an hour away from home and suddenly my muffler and exhaust started dragging— 49,000 miles, 5 years old AND just passed inspection A WEEK AGO. Luckily, it didn’t become completely unattached because that could have caused an accident as there were cars behind me. Complete safety hazard
This vehicle was sold as new when this vehicle had a defective Turbo Underboost issue from a ECM Issue previously prior to the 2022 Trailblazer being sold to us. This vehicle has a shift to park issue which sticks when you try to Park the vehicle. Next This vehicle has had 4 prior incidents of attempted repair of this Turbo Underboost and a failure to pass emissions which lead to the engine and transmission failure of this vehicle. I have waited since July 6, 2025 of this vehicle being in the shop no rental no loaner. Now no replacement vehicle. For more than nine months and a General Motors open claim since 07/06/2025! GM is hiding the truth about Recalls and Road Hazards not listed to vehicle like this 2021 Trailblazer and other GM vehicles that GM refuses to replace and cannot repair or cover the additional financial hardship placed on unwitting consumer as they sell defective vehicle wholesale or as new vehicles through Chevrolet Dealership across this goble. We must STOP this from happening. GM is not even honoring the Government Guidelines forcing victims to hire counsel to buy time and prevent massive Recalls like ours.
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.

My 2021 Chevrolet Trailblazer has a defect in the gear shifter system that intermittently fails to recognize when the vehicle has been shifted into “Park.” When this occurs, the vehicle displays a persistent “Shift to Park” warning message and prevents the engine from being turned off or the vehicle from being locked. This malfunction creates a safety and consumer concern, as I am unable to exit and secure the vehicle and am forced to remain inside or leave the vehicle running and unattended. The issue interferes with normal vehicle operation and poses potential safety risks, particularly in situations where I need to quickly power down, exit, or secure the vehicle. After a quick internet search, this issue appears to be affecting multiple others with the same vehicle (2021-2023). A prior lawsuit against GM also resulted in a settlement and recall for older model Trailblazers, but unfortunately did not include the newer models that are experiencing the same known issue. • Gear shifter system is malfunctioned, specific reason and/or part is unknown. Vehicle is available for inspection upon request. • Safety risks noted above. • Problem has been confirmed over the phone and via text by local Chevrolet dealership. Only solution offered was to pay over $650+ for a fix that is not guaranteed to fully resolve the error. • Vehicle or component has not been physically inspected by manufacturer, police, insurance reps, or others. • No warning lamps, messages, or other symptoms occurred prior.
The rear hatch interior trim that seals the hatch from exterior elements and sounds continuously comes off, even after having dealership to repair/replace. The trim will not remain in place and is a distraction while driving and hearing out of vechile noise. And the winter weather causes car not to maintain a constant heat temp
After trying to remove rhe key from ignition, it gets stuck and won't come out unless I turn the car on, shift it into drive, wiggle the steering wheel, and try it again. Sometimes it works. Alot of times it take 5-10 min to get it out.

The issue is the yellow engine light lit up on the dash of my 2021 Trailblazer in late August of 2025. At the same time, the cluster displayed the message "Engine Power is Reduced". Over the next few weeks my car engine would randomly stall out while I was driving! As you can imagine, this is a very unsafe driving condition. My car stalls and I'm in traffic and have no ability at all to control the vehicle. This happened at least 4 times to me. When I checked the On Board Diagnostic codes on my vehicle the system reported back U060F (Mass Air Flow Sensor). I searched online for this condition with 2021 Trailblazers and found GM Service Bulletin number 22-NA-008, dated March of 2022. This Service Bulletin clearly shows that Chevrolet were well aware of a problem years before it occurred to my vehicle. So, in October I took my car to Bowman Auto Center, explained all of the above to them, and I mentioned the Service Bulletin that I found. Their investigation found that, indeed, the cause of my engine stalling was broken wires to the Mass Air Flow sensor (MAF sensor). Bowman repaired my car and billed me $364.44 as shown on the attached 2-page Repair Order. I tried to make the case with the Bowman Service Department that this should be a warranty repair, and paid by GM. Bowman responded that it was only a Service Bulletin from GM for the issue, and the customer is responsible for payment. I am astonished that repair of this product Design Failure, which results in an unsafe driving condition, would be paid for by the customer! The reason I call it a Design Failure is because NO wiring should break during the life of a vehicle. Engines rock and move, and the Trailblazer design should have compensated for this engine movement by having a sufficient slack loop designed into the wire harness leading to the Mass Air Flow sensor. I filed a case with Chevrolet, number 80982656, but they declined my request for reimbursement $$.

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.

Experiencing reduced speed, rattling noise, check engine light, power steering light on. Chevy app shows throttle control system and antilock break system error messages. Took to Chev dealership. Advised it was fuel injector (1 /4 was burned out). Had all 4 replaced ($3000). Picked up car on a Friday, vehicle was having the same issues next day Saturday. Took it back on Monday, it is now Wednesday and they’re saying it’s the turbo charger now (another $3000). Mechanic couldn’t figure out what the issue was so it took 3 days for him to now say it’s the turbo charger. I think it was the turbo charger from the get go! What’s the purpose of the diagnostics ($250)? Isn’t it to pinpointed the issue? 1st day, took him 4 hours to say it was the fuel injector. 2nd time around it took 3 days. I kept showing them and telling them it’s the throttle control system! They’re trying to rip me off! Mechanic is saying he’s been test driving it and no issues. I took a photo of my mileage before I handed them my car and it was 79,190. The mileage today says 79,191. How and where is he test driving it if it’s only been 1 mile? Reverse and forward ? They’re lying

Shift to park error. I put the car in park but it tell I get a notice to shift the car in park when it’s already in park. Beeps and continues to tell me to shift my car in park when it’s in park. Turn off the car get out and close the door and the notice and beeping continues while the car is off and in park. Been happening since I bought it.
Vehicle has given me a "Shift to Park" message when the sift is all the way up and off at park. You basically has to push hard for the message to go away.
Park to shift error. Vehicle will not turn off while in park, instead gives an alert to "shift to park" even though the vehicle is already in park. Due to faulty park switch or wiring in the shifter assembly
My vehicle started flashing “shift to park” about 2 weeks ago, after being in a GM dealership for 18 days for repair. I immediately notified them my CEL was back on and what it was showing on my dashboard ( shift to park). I dropped it off on a Saturday and that same day they told me they could not figure out what was wrong with it. I texted the Service Advisor of the notification I was having and if that was the issue to which she did not do anything about. The issue is that it will stay on, and flash and can drain my battery out and it will not allow me to lock my car or it tells me that my vehicle remote is not inside to turn it off. When I called the dealership about it, they told me that the S.A. Did not mention the issue I was having and she was not concerned with it- and they would look at it but will charge me for it ( while they already had possession of my vehicle). Dealership told me they saw no code for it and it wasn’t showing up on their end when they had my car. But the day I picked it up, and put it in park it started doing the exact issue I told them about. They told me they were getting my car to “act up” and they would of clearly seen the notification on my dash and did not look into it. Insurance has not looked into it and no one seems to be able to help me and I’ve already paid $1000.00 to two different body shops to fix my car and it’s still having that issue. At current, it’s flashing “shift to park” and I can’t get it to stop and I have to keep turning my car on. It’s a huge safety issue as it’s going to drain my battery out or cause me to not be able to start my vehicle
multiple times of getting the warning that i need to "shift into park" when the vehicle is in park. i did have fixed at my local dealer but did have to pay, I know this is been an ongoing issue with many trailblazer . Chevy should look into recalling the failing part.
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.

The contact owns a 2021 Chevrolet Trailblazer. While the contact's wife was attempting to park the vehicle, the shift to park warning light illuminated. The dealer was made aware of the failure; however, the vehicle was not diagnosed or repaired by an independent mechanic or the dealer. The contact was informed of an undisclosed recall; however, the VIN was not under recall. The manufacturer was made aware of the failure but provided no assistance. The failure mileage was approximately 79,000.
My vehicle displayed a Shift to Park message even though I was already in Park. I could not turn off the engine, I could not lock my car. I had to go back into Drive and then Park mode and wiggle the shifter multiple times to get it to recognize Park and turn off the car. This is now happening almost every time I drive the car. I did an internet search to see how to rectify the problem only to find that this exact issue has plagued GM vehicles for a decade and they still have not chosen to rectify the faulty part. There have been multiple recalls and class action lawsuits for the SHIFT TO PARK fault but not for my vehicle year YET! There are many Trailblazer owners who are experiencing this exact issue (on online forums) and GM so far is refusing to take responsibility and issue a recall to fix the issue for owners and also to stop using this faulty system in their cars. I have reached out to GM about this multiple times the past few weeks and requested they pay for diagnostic and fix the problem because it is a common and known problem with GM vehicles but they want me to pay for it myself and the repair and then they may decide to help out - unacceptable in my opinion. To be honest there needs to be a recall NOW and GM needs to be forced to change the components in all new models to stop this happening in future models going forward. This problem can cause the car battery to drain, it can cause the vehicle to roll away if it’s not recognizing it’s in Park. Thankfully that hasn’t happened to me but others have had this happen. Not being able to shut the engine off or lock my car is a problem. This is a safety issue that needs addressing. I have lots of messages and communication from General Motors which I have attempted to attach the screenshots with the photo below but get an error message on the upload page.

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.

The transmission shift control / transmission range sensor / shift interlock solenoid in my Chevrolet Trailblazer is malfunctioning. When I shift the vehicle into park, it fails to recognize the gear change and displays an error message stating, “Shift to Park.” As a result, I'm unable to shut off the engine properly, which poses both a safety risk and a serious inconvenience. I strongly urge the NHTSA to investigate this issue thoroughly and consider issuing a recall to address the defect.
vThe contact owns a 2021 Chevrolet Blazer. The contact stated that while driving at an undisclosed speed, there was an abnormal sound coming from the vehicle. No warning lights were illuminated. The vehicle was taken to the dealer, where it was diagnosed with a crack between the muffler and front pipe. The contact was informed that the muffler needed to be replaced. The vehicle was not repaired. The manufacturer was made aware of the failure but provided no assistance. The contact was advised to contact the NHTSA Hotline to report the failure. The failure mileage was approximately 57,850.
I get a shift to park warning after putting the car into park. I’m not able to turn the car off, this has drained the battery and caused safety issues for me and my child
