ELECTRICAL SYSTEM, UNKNOWN OR OTHER
The infotainment system which controls the radio,backup camera, onstart,and other safety components stopped working i took it to a gm certified dealership and it has just been all bad from there. gm has horrible customer service and so does the gm certified shop in michigan city i took my truck in that I only had for 11 months because the infotainment center went of paid for two diagnostic tests they still couldn't] find the issue and now they they're changing me 1,037.76 for a radio which they dont even know if it's going to fix the problem which if it doesn't then I have to pay more money for another diagnostic test and more parts and because I got mad and said I'm paying for a guessing game the dealership told gm that because I had some aftermarket equipment in my vehicle that that caused the issue bullshit the stuff never got plugged into anything at that point the day of my appointment with the audio shop the screen went black with no sound they're all full of shit and didn't want to take responsibility for the widely known issue with the telemedic system

car was driving fine, went up a hill then check engine light came on with warning that stated "reduced engine power." drove it approx 8 min to home. parked in garage. Next morning, took to Firestone Complete Autocare as that was the first place available. Just got a call that the whole turbo assembly needs to be replace costing almost $2000 and will be without a car for about a week. 5 year warranty expired 3 months ago and there is less than 47,000 miles on it. It is currently at the shop so I don't have a bill yet, but they told us how much when they told us what was wrong with it. This is unacceptable! Reading about and hearing about this complaint all over the internet!!!

ENGINE
All 3 bolts that connect my tailpipe underneath my car failed. This caused the tailpipe to disconnect from the car, meaning I was pushing the pipe as I drove. Luckily it failed when I was at an intersection, and I heard the noise. I was able to drive slowly into a parking lot and disconnect the exhaust for a repair. However, if I had been traveling down a highway when it occurred the pipe surely would've hit a bump and then jammed the rest of the exhaust back up into the under carriage of the vehicle and perhaps causing an accident. I did email the dealership I purchased the vehicle from, but they were unaware of an issues on the vehicle. However, from searching online, there are other 2022 Trailblazer owners experiencing the same issue. There were no warning lights before during or after.

The shift to park is defective on mine and many other GM vehicles. I had it previously repaired under manufacturer warranty and then again in just over 16,000 miles driven which fell outside of the manufacturer warranty. I had to pay out of pocket for the repairs and GM refused to reimburse me for the repairs. GM has a service bulletin recognizing the defective part and still refused reimbursement. The shift to park causes the vehicle to not recognize the vehicle is in park preventing it from shutting off. This causes the battery to drain and need replacement as well. I have now had the shift to park and battery replaced twice in under 45,000 miles. The service advisor for Seminole Chevrolet advised this part should last minimum of 100,000 miles and it is a known issue. This causes a major safety concern as the vehicle doesn't shut off and could cause someone to be stranded anywhere. It is concerning that a major vehicle manufacturer is continuing to manufacture and use known defective parts. My vehicle has been inspected and repaired both times at Seminole Chevrolet in Sanford, FL. I have also contacted the Executive Resolution team at GM with no resolution. The shift to park and low battery illuminates on the dashboard before the vehicle completely shuts down due to the battery failing caused by the shift to park defect.

ELECTRICAL SYSTEM, POWER TRAIN
Component Affected: POWER TRAIN: AUTOMATIC TRANSMISSION / TRANSMISSION CONTROL MODULEDescription of Safety Defect:The vehicle is experiencing a severe, intermittent, and violent mechanical "garage shift" engagement lurch. This occurs specifically when shifting the gear selector from Reverse to Drive during a cold-start cycle.When the gear is selected, there is a distinct hydraulic delay followed by a violent mechanical slam that causes the entire vehicle to violently lurch forward. This unintended vehicle movement occurs even though the engine has naturally idled down completely below 1,000 RPM, and while the brake pedal is fully and firmly depressed to the floor.Safety Hazard and Consequences:This defect poses an immediate and severe safety hazard. The mechanical force of the lurch is strong enough to potentially overcome the vehicle's braking system or cause a foot-slip off the pedal, resulting in sudden, unintended vehicle movement. This creates a high risk of a low-speed collision, vehicle damage, or striking a pedestrian or property during tight parking or garage maneuvers. General Motors' internal service bulletins (such as Bulletin 24-NA-009) indicate known issues with sticking clutch regulator valves or solenoid over-travel causing line pressure spikes in these modern transmissions, yet no safety recall has been issued to permanently address this dangerous powertrain defect.

Shift assembly kit, it is available. Dealership has to order part for inspection. Still passed inspection. Possible unintended rollaway accidents. Not being able to lock the vehicle as well. Yes, it’s been confirmed. There’s also so many class action lawsuits against GM about this matter. Why isn’t there a recall already?! Getting the “shift to park” message in my vehicle for the 2nd time now in less than 4 years. The shift assembly kit was replaced back in December 2022. Apparently it needs to be replaced again because of a switch.

ELECTRICAL SYSTEM, UNKNOWN OR OTHER
When putting the vehicle in park and turning off, a warning message will appear that states "Shift to Park" and initially a nudge of the gear shift would clear the message, after one week, a simple nudge does not clear the message. The vehicle will not turn off and continues to beep, you have to put vehicle in gear (D or R) move a few feet, return to P, press very firmly on the brake and press the ignition button, this may or may not clear the message and it could take a few attempts of these steps to clear.

ENGINE, UNKNOWN OR OTHER
The two components that failed were the water pump and the coolant control valve which caused the engine to overheat, resulting in me having to pull over along the side of a busy highway putting me at risk for injury while the vehicle cooled down. It would be available for inspection upon request. This was dangerous mostly to myself due to having to pull over on the side of a busy highway and wait until the vehicle could be somewhat ok to be driven the rest of the way home. I had to drive very slowly home with my hazards on at a very low speed. Vehicle was brought to a nearby Chevy dealership the following morning. They had the vehicle for two days and claimed they could not get the problem to present itself, however, within five minutes of me driving it off the lot it overheated resulting in having to pull over again on a busy highway. An independent service center had the vehicle and diagnosed it initially as an intermittently failing water pump. This repair did not resolve the issue 100% as the vehicle began to slowly overheat again within 18 minutes of highway speed driving. Car was towed back to repair shop from my place of employment. They were able to get it to present the issue and diagnosed it as the coolant control valve. This has so far appeared to resolve the overheating issue. The vehicle has not been inspected by the manufacturer, police or insurance rep/others. The only warning that came up was on the info screen above the steering column advising me the engine was overheating and was in idle. Immediately upon seeing this I pulled over to prevent any damage. Temp gauge was all the way in the red. Fan was blowing hard. This has never happened previously and there were no other warning lights of any kind on the dash to indicate an issue. This incident happened on 6/2. Please be advised, this vehicle has since been repaired and has ran me $2300 as it is out of warranty.

I used the jack for the first time of buying the vehicle new. I jacked the vehicle up to put the spare on and the scissor jack folded up and the car dropped. So I looked up if there was a recall on it and there isn't but there is on other vehicles. Note: the car was on level hard surface ground and I placed the jack in the correct location.

POWER TRAIN
I am having issues with putting car in park. Keeps showing not in park and will not shut off until I yank on handle. Getting worse & taking so long. Took to dealership and they said probably the harness and would cost $400 to $600 to fix. My research shows they have had this issue since 2018!! Only recall I could find was in Ohio. I feel angry they still keep using a defective part and expect us to pay to fix. I am older and on fixed income & don't have the money. Also why should I when it's their ongoing issue. I'm scared of this not letting me shut off car till I run out of gas!!

ENGINE AND ENGINE COOLING
The contact owns a 2023 Chevrolet Trailblazer. The contact stated that, while driving on several occasions with the auto start-stop feature activated, the vehicle appeared to shut down at a complete stop as the infotainment screen and dashboard lights turned off. The vehicle restarted automatically but shuddered during startup. The dashboard lights and the infotainment screen became operable. The vehicle was not diagnosed or repaired. Additionally, the contact stated that while driving at approximately 30 MPH, the thermostat needle went to Hot, and the Check Engine warning light illuminated. The vehicle was steered to the side of the road and turned off for approximately 15 minutes. Upon restarting the vehicle, the check engine warning light remained illuminated. The vehicle was taken to an independent mechanic, where it was diagnosed that the coolant flow control valve had failed and needed to be replaced. The vehicle was not repaired. The manufacturer was not notified of the failure. The failure mileage was approximately 88,251.

SERVICE BRAKES, ELECTRICAL SYSTEM, FORWARD COLLISION AVOIDANCE: AUTOMATIC EMERGENCY BRAKING
While driving on Thursday, June 4, 2026, the vehicle experienced a sudden and complete failure of the electronic braking/power brake assist system. Simultaneously, multiple safety warnings illuminated on the dashboard display, including a persistent service wrench icon, a traction control warning light, and a lane-keep assist indicator light. Due to the loss of brake assistance, the vehicle was unsafe to operate and had to be towed/driven directly to a licensed dealership for emergency diagnosis. The dealership technicians subsequently inspected the vehicle and reported that the entire electronic braking system had suffered a total failure and is completely non-functional. Despite multiple technical service bulletins and recalls issued for similar vehicle builds regarding electronic brake boost interruptions and mechanical brake vacuum pump failures, I am being forced to pay for these critical safety repairs out of pocket. A sudden loss of braking power poses an immediate crash hazard, and I am filing this report to urge the NHTSA to investigate why this manufacturing defect is not covered under an active safety recall for this specific vehicle configuration.
