2022 CHEVROLET TRAILBLAZER Power Train Problems

Vehicle experiences intermittent loss of acceleration at highway speeds. While driving at highway speed or going uphill, up ramp, down hill, down ramp the engine loses power and enters reduce power mode, making it difficult or impossible to maintain speed or safely merge with traffic. The issue is unpredictable and has occurred despite prior repair attempts. Vehicle is covered under a GM special turbo warranty for a known defect. Warranty came out Oct 2022, Due to the loss of power the vehicle is unsafe to operate and is currently at the dealer.

When parking and trying to shutoff vehicle a warning stating that the car needs to be shifted into park needs to be performed even though it is already properly in the parked position. The car cannot be shutoff and remains running until several actions of shifting the car in and out of the park position.

The cruise control system intermittently fails to engage indicating an error with the system. After several random occasions it was finally determined that the issue is related to the brake pedal sensor not determining that the brake pedal has been fully released. It requires having to manually pull the brake pedal up to properly set the sensor to allow the cruise control system to engage. This does not present any clear danger in itself, however, after having the vehicle inspected the manufacturer service center states that the entire pedal assembly has to be replaced because of worn parts and that the pedal may continue to get worse. While the mileage has taken the vehicle out of warranty that covers this issue the car is primarily driven on the interstate with minimal wear and tear on the pedal assembly.

“Shift to Park” message came on the dashboard. Car would not change gear or go into reverse or drive. Basically stuck in Park position. Car kept peeping sound nonstop for over 20 minutes. And it drained the battery. Car would not drive. Had to have it towed to the dealership I brought it from 45 miles away. I had to pay $656.72 at dealership to get it fixed. The dealership removed and replaces the shifter assembly which cost $656.72.

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.

The contact owns a 2022 Chevrolet Trailblazer. The contact stated that while in park(P), the gear failed to shift into the intended gear. The contact wiggled the gear shifter for the vehicle to recognize that the gear shifter was shifted out of park. The shift to park error was displayed. The vehicle was taken to the local dealer, but was not diagnosed or repaired. The manufacturer was contacted, and referred to the NHTSA Hotline. The failure mileage was approximately 32,700.

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.

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.

The vehicle began to display 'Shift to Park' on the display even after the vehicle was in the park position. This started periodically over a few days, but then became a regular occurrence within a week. At first this could be resolved by shifting back out of park and back into park, but that became less effective as time went on. The vehicle will not shutdown fully when this warning is displayed and therefore can cause a battery drain condition, which can result in a safety risk returning to a vehicle with a weak or dead battery. This occurred at 37 months of ownership with ~28,100 miles on the vehicle. In researching to understand the problem, I discovered that there are many instances of this same issue occurring at about the same time period, as well as there being several class action lawsuits on the identical issue, which shows that it isn't isolated. Further, the cost of this repair is a replacement of the shifter assembly at nearly $700 on a $24,000 vehicle less than 3 years old, because the failed inexpensive switch isn't repairable. Repair information is available, but the system isn't allowing for an upload of the files.

The gear handle, when I place in park, will NOT park, therefore, I am not able to turn off my car. I have to jiggle, push start button and try over and over. This is a 2 .5 year old vehicle.Warning alert comes on stating the obvious, Unable to park! Also, it sounds like when I do drive of like the dragging, rough sound, which sounds like the gear is not fully in drive. Again, this is a new vehicle. It is unsafe and getting worse. Thank you.

Alert for shift to park keeps alerting after already in park. I have to turn car on and off at least 20xs to get notice to shut off . I cannot leave car with notice on dash screen or it will beep at me and drain battery. I went to service at Chevy and they told me this isn’t a recall and the part I need is a new shifter and it will cost me money on a 3 yr old car to fix with 14000 miles. I am extremely upset because the part is unavailable and no estimate when I can get it fixed. I’ve been dealing with this for a few months and it take me 20mins off and restarting to get error to go away. I need answers !

Shift to Park is Displayed on the Driver Information Center (DIC) When Vehicle attempting to turn vehicle off. This is a known issue to manufacturer, but not warrantied fixes are being offered. (TSB 23-NA-119)

Shift Control Assembly (Shift to Park Issue) I bought a 2022 Chevrolet Trailblazer custom, and around 57,550 miles it started throwing a shift to park error message. This does not allow me to turn my car off complete as it does not recognize it’s in park. It has been looked at by Dealer and parts are back ordered no known fix for it. This is a well known issue from Chevrolet but they only cover it under bumper to bumper and not Powertrain, but everywhere I read it’s a Powertrain issue. This will drain my battery inhibiting my ability to use my vehicle which is only 2 years old. This could be a safety concern since the car isn’t recognizing it’s in park therefore not allowing it to shutdown and leaving electricity running through it all the time. Let alone a huge hassle for the drivers of the vehicle.

For about a month now my vehicle is telling me to put it in park when it is already in park. Have to restart multiple times and go through all the gears put it back in park turn it off and still get the "shift to park" error. It does not happen every time I use my vehicle, but it happens so much I am unsure if it is safe to use. Even though it shows it is in park I wonder is it really? I have called the dealer where I purchased it for them to look at it and they will not even schedule an appointment because they say the parts are on back order and they have no idea when they will get them. This is the first brand new car I have purchased and after having a lot of secondhand vehicles I went back to Chevy. I am very disappointed in Chevy it only has 23000 miles on it, and they are not doing anything to fix this, I would not recommend Chevy/GMC to anyone.

Bought last year in November. Starting having "Shift to park" alert when car was in fact, in park. Took me 5 minutes to successfully turn my car off. It happens intermittently and at first it was just one and done, now (after about a week) it's almost every time I park. It's very frustrating. I called the dealership and they can't get me in for 2 weeks. Unsure if they will be able to diagnose/fix the problem.

Noise only when cold at front tire passenger side Nosie at front tire passenger side while steering. Check engine lite code PO299 Turbocharger/supercharger underboost-engine power is reduced. Replaced tire at 24600 miles. While driving at 65 mph, the forward collision avoidance system activated, and the car stopped at 65 mph. It happened 5 times that car fully stopped, and numerus time I get forward collision activated but then nothing happens. Imagine on freeway from 65 to 0 brakes by itself. Hard shifting and body shaking while accelerating. Hood is shaking while driving on freeway.

Nearly every time I park my car and shut it off a message pops up on the message board that says SHIFT TO PARK even though it is in park. I have to restart my car MULTIPLE times and shift to another gear and back into park before the message goes away. This has been happening for a couple of weeks but is getting more frequent.
