Our 2021 Chevrolet Trailblazer was purchased last December in 2023. For at least a week now the "shift to park" alarm goes off, practically every time we put it in park & turn the engine off. It wont shut up. The lights stay on, and it won't let you turn the alarm on. Sometimes if I wait and go back & jiggle the gear shifter through different gears, and turn the engine on & off it might stop, show me a "check the rear seat" warning, and be alright( until the next time I drive it and try to park it). It's becoming more & more persistent. I checked with the Chevrolet dealer, and they said the vin number isn't listed under the recall, so GMC won't cover it. We don't have the money to take care of it ourselves, and don't know what to do.

The contact owns a 2021 Chevrolet Trail Blazer. The contact stated that after shifting to the park position the message "Shift to Park" was erroneously displayed and the vehicle would not shut off. The contact had to shift multiple times before the transmission switched to the park position and the engine was able to be shut off. The vehicle was taken to the local dealer who diagnosed that the shifter was faulty and needed to be replaced. The vehicle was not yet repaired. The manufacturer was also notified of the failure and confirmed that the part was on backorder. The failure mileage was 16,600.

I was driving on the highway and out of nowhere the exhaust pipe after the converter had fallen on the road at highway speed. It happened to be the rear pipe leading to the muffler, which is behind the rear bumper, so when the pipe fell, it fell facing the front of the vehicle. The fact that I was able to get the vehicle to a nearby rest stop safely was amazing in itself, that nothing more tragic happened at highway speed with the exhaust pipe facing forward on the ground is a miracle. How does this happen to a 3 year old vehicle? The flatbed driver said he thought there was a recall on the Trailblazer, as he had towed several with the same problem. I called GM, they assured me that there was no recall and could schedule me a service appt to have the vehicle assessed and repaired, I declined, I already have an estimate from my local repair facility, which is still quite a bit of money.

After putting vehicle into park and shutting off the engine, the warning appears “shift to park” and will not allow the vehicle to completely shut off. For the past few months I have been able to maneuver the shifter and the car recognize it is in park, however this past weekend nothing would work and the vehicle stayed in accessory mode until the battery died. I have spoken to two local dealerships and they are aware of the problem. I am currently awaiting a local repair shop to research the issue and get back to me if they can repair it and what the cost will be. This began in September, I am unsure the exact date. Upon researching this, there are hundreds of vehicles that have had or are having this issue going back as far as 2018 at least. General Motors has been aware since then and only issued an inquiry to dealerships last November. This is clearly a defect in manufacturing that should have been recalled and remedied long before now. I am without a vehicle and out of pocket for a repair that should not have occurred.

On [XXX] I shifted my 2021 Chevy Trailblazer to park and and was unable to shut off the vehicle. When I shifted it to park it kept displaying an error "Shift to Park" on the dashboard, but the shifter knob was correctly in park. I attempted to press the power button to turn off the car and it wouldnt do anything but beep. I tried multiple times to shift to park to get the car to recognize it was actually in park and turn off the vehicle but I was unable to do so. I was frantic and panicked to find I could not turn off my vehicle as I park on a apartment complex lot. That day I took the car to Henna Chevrolet in Austin Tx for repair. They said the part was on backorder from GM with no ETA. It is now November 1st and there is still no ETA on when I will get the part for my car from GM. This has been going on for 3 weeks now with no end. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

When attempting to park the car I am able to shift into park, however, I get a message on the dashboard to “shift to park”. Dashboard also shows a “p” to reflect car is in park creating a contradiction on the dashboard of displayed items. When this occurs the car will not shut off. Dealer service has indicated this is not producing an error code, they have had many complaints, and the issue is not covered by power train warranty and part is back ordered. I am very concerned about the safety of my vehicle given the indicated failures of the shifting mechanism and Chevrolets inability to remedy the issue due to unavailable parts.

After placing the vehicle in park I get the “shift to park error”. I can’t leave the vehicle, or lock it. It can take any where from 5 to thirty minutes for it to actually read the shift. My car is now not reading my key 80% percent of the time. The vehicle turns off while driving down the road. Saying no “remote detected”. The key has been locked in the Car twice. Which should be impossible. I’ve been stranded outside of my vehicle at night in Atlanta for long periods of time. Trying to get the vehicle to unlock because it is not reading the key.

The rear shocks on the 2021 trailblazer are faulty and are blowing out causing the rear tires to bounce and eat away at the tread exposing cords becoming a safety hazard. The rear shocks blowing out is happening on several 2021 Trailblazers causing there to be a national back order leaving these vehicles and drivers to be at risk of serious accidents and injuries.

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!

Odometer: 50,379 Purchased used on April, 1 2024 Odometer: 47,027 Brought to dealer on 8/28/2024 for service. About two weeks ago we had a "Shift to Park" message is displayed on the DIC after the vehicle was placed in Park and shut off. Started it again and then put it in drive then back to park. Message went away. Then over the course of the next week this happened many more times to the point where we were stuck in a shopping parking lot because we could not leave the car as it kept beeping to fix the issue. Made appointment with dealer. After Diagnose from dealer they said it needed to perform Service Bulletin #23-NA-119, recommend replacement of transmission control. They at first wanted us to pay for it and we advised dealer we had a Chevy warranty. After a few days they advised it would be covered under warranty except for our $50 deductible. Main problem is the part # 13545091 was not available locally and dealer had to research to find part. Advise it could take until 9/26/24 to find part. This should be a no charge RECALL by the Mfg. as this can be a safety issue and to ensure more parts are in stock by dealer.

My 2021 Chevy Trailblazer has an error reading “shift to Park” that randomly appeared 2 weeks ago, now is doing it almost every time I stop my car, error has also cause my battery to die. When error is showing my car will not shut off. Took to a Chevy dealer and recommended changing the gear shift assembly, can’t guarantee it will fix the problem. They have ordered the part but $450 plus parts and labor for not a guarantee is concerning. I also travel for work and have been left stranded because of this issue.
