SERVICE BRAKES, ELECTRICAL SYSTEM
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.

POWER TRAIN, ELECTRICAL SYSTEM
I am reporting a recurring “Shift to Park” malfunction with my 2022 Chevrolet Trailblazer. When I shift the vehicle into Park and attempt to turn it off, the dashboard displays a “Shift to Park” message, and the vehicle remains in Accessory Mode rather than shutting down completely. The vehicle continues drawing electrical power and the battery drains overnight. This condition poses several serious safety risks: 1.The vehicle may not consistently detect or hold the Park position, creating a potential roll-away hazard. 2.It prevents the driver from shutting off or locking the vehicle, leading to security and electrical safety concerns. 3.If the vehicle remains powered in an enclosed area, it increases the risk of carbon-monoxide exposure. I understand this issue has been widely reported by owners of late-model GM vehicles, and appears related to a defective park/position switch or shifter assembly. I request a thorough investigation, appropriate repair, and confirmation whether this defect falls under a service bulletin or recall.

ELECTRICAL SYSTEM
There is something wrong with the battery charging system, this is a known issue for GM. I've brought it to the dealership to address the issue and they do not know what is wrong or how to fix it. Sixteen times since I got this vehicle it has flashed a warning "service charging system: your vehicle may stall because the battery is not charging properly. Schedule service soon." I obtained this vehicle April 30th with 5 miles on it. They still do not have a fix for this, the dealership stated they would contact me when there is a recall....

ENGINE, VEHICLE SPEED CONTROL, STEERING
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

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

POWER TRAIN
Vehicle displayed "Shift to Park" error and would not shut off. This occurs after the shifter is placed in the park position. By any standard, a defective component that prevents the car from being shut off is an extreme safety concern and needs immediate attention. Additionally, the instrument panel remains illuminated and the aux power items continue to function. This has happened multiple times and has drained the battery on several occasions.

POWER TRAIN, SERVICE BRAKES
My car has been well maintained and always taken for service according to recommendations from the manufacturer. My brakes have ALWAYS squealed since I first bought it new but apparently there’s nothing they can do about it so I’ve just dealt with it. Now a more serious concern I am having after manufacturer warranty is my dash is displaying a shift to park message every time I shift into park and turn off my car. I also might add that this has been going on with others! Chevy doesn’t think it’s a concern when it is a very serious issue. I have children and once when I went to get gas after almost being on empty my car wouldn’t turn off because of that error and I couldn’t get gas. I tried turning it off and on multiple times to fix but it just didn’t want to work when I needed it most. I have to aggressively charge gears go get it to work most of the time. It’s a serious issue that has been brought to their attention and shouldn’t be happening to a vehicle under 50,000 miles and well maintained. These issues need to be addressed there’s no reason I should have to pay to fix an issue this extensive and costly in a 2022 vehicle.

STRUCTURE:BODY, UNKNOWN OR OTHER, ENGINE
The exhaust and muffler completely detached from the catalytic converter/exhaust manifold while driving down the road. If we were driving at a higher rate of speed, the exhaust pipe could've caught on any imperfection on the roadway and shot the rear end of the vehicle up and then potentially caused an accident/death. This has happened to many I have discovered upon further research and is a common problem with the vehicle according to the dealership. Vehicle has been towed to the dealership to be inspected and/or repaired. Zero warning signals, lamps, or messages.

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

ELECTRICAL SYSTEM, SERVICE BRAKES, STEERING
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.
