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.

The dash and radio have gone out while driving several times now. Was driving out of state on vacation and it has gone out on us over 9 times. We will be driving and the dash goes black. You can’t see your speed, gas or radio.

I received a email from carfax stateing the truck had diagnostic testing and is the transmission in the engine system. It’ll start up but you cannot drive it. It shows that are passed the state inspection on June 27/2025 stating that the truck passed the inspection how the truck went past inspection and it’s not driveable and I don’t have it. There’s no way that’s fraud you gonna say that the truck pass inspection when you can’t drive it normally when you go get a state inspection and once they do it and it pass they give you the keys and put the sticker on it. In this case the truck is still at the dealer and it’s not driveable. You can’t drive it. It’ll start up. They change the oil rotated to tires but it’s not driveable. You can’t drive it.

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.

Hift to park the vehicle began to display 'shift to park' on the display even after the vehicle was in the park position. 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. Vehicle has only 23,478 miles. 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.

Check engine light is on. Took to o'reilly and had them put their tester on it to get the codes. Codes show p0700 and p1467. My cruise control and auto start will not work. My mechanic said this is an issue that should be fixed free of charge but no recalls show for my vehicle.

Upon starting vehicle it would idle for 30secs to 1 minute before shutting completely down, then would prompt to engage brake and push start/stop button to turn back on. Two different times while driving at 60+ mph the vehicle completely stalled losing power steering and brakes. Both times when the vehicle shut down it would say to push start/stop button and then place vehicle in park, engage brake to restart. When the vehicle stalled I was getting onto a highway and was about 2 seconds from being hit from behind by a semi while I was at almost a standstill while they were doing 70+. Have taken it back to the dealership both times and it died on them once but there is no solution to this issue as no codes come up.

I could turn off the engine after driving, but the key stays in the position between the engine being on and the car being off (for example when you can listen to music but your car isn’t running). The battery light came on after the issue started and so the car service place charged us to replace the battery, because they had to turn on and of the car a lot and the car had to continue to run. I took it to a car service place and they ran tests and called chevy test support to run diagnosis tests. They can’t figure it out. They think it might be the body control module. Not sure what that is. The car only has 31,000 miles on it and this is a safety issue because what if this happens and the steering wheel locks or it becomes a rolling hazard. This would affect the driver and others. There were no lights or errors indicating a problem before this happened.

Traded in a good 2018 chevy cruze for a Trailblazer that just keep cutting off and wouldn’t start back contacted dealer 9,989 miles 11 months old it would cut off it said the theft determine system needs service then one day it just wouldn’t start at all it would cut off while driving I had it towed to dealer I had been telling the dealer fruitless and for 4 months fruitless I traded a good chevy they gave 9,500 and I put towards the trail blazer 9 ,989 miles I am 65 years old and half rude company every time the vehicle will cut off it will state that the theft determine system needs to be serviced. It’s a software.

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.

Engine power reduced came on after I was driving from a patient’s home. My car started driving very rough. I had to pull over because I was in danger of being hit from behind. I took my car to a mechanic and was diagnosed with the code dtc p2714. I looked online and there are a lot of people having this issue and being put in dangerous situations when we drive. Chevy knows about the issue and has not issued any recalls. Unfortunately for me my vehicle is past the limited warranty so now I have to save up money to get my transmission serviced. I’m never buying american again. I could’ve been really hurt when my engine cut off.

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.

Found standing water in spare tire well. Back seat constantly wet, growing mold. The whole back area is moldy, mold under driver seat. My back passenger door seal has mold and water. Seat belts in back, mold. I had to wear a mask just to drive to the store. The mold turning black the day I took it to a shop for a water test. It's been two days and I still haven't heard anything about the water test.

Issue: when the vehicle is put into park and the ignition is turned off, the vehicle may not recognize that it is in park and a message will appear. This can make it difficult to turn off the ignition and remove the key. The “shift to park” message appears in the driver information center of my 2022 chevy Trailblazer. The cause of this is a malfunction in the park switch inside the shifter assembly of my chevy Trailblazer. My local chevy dealer advised me that some vehicles are getting recalls for this issue, however my vehicle has not. There are currently two class action lawsuits pending on this issue - one in tennessee and one in ohio. I would just like my repair to fall under a recall since there are so many issues throughout the united states on this part it does not seem fair that I should have to pay almost $500. 00 (parts and labor) for something chevy knows is defective.

Onstar module that is supposed to working in case of a crash or another emergency stopped working back in November 2024. It also is attached to other operations such as the vehicles microphone. I took it to the dealership Chevrolet said they would pay half of the replacement. My vehicle is not the only one. There is a forum online and other gm vehicles are having the same issue.

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.

When I place my car in park, a "shift to park" message appears on the dashboard. I am unable to fully turn my car off and the car will ding at me. I have tried driving around the parking lot, pushing the shifter from side to side and into another gear then park again, going forward and backward, but the problem still exists. It started to occur more frequently, until it occurred every time I drove the car. I'm not sure if the car is actually in park, so when I finally get it to turn off, I place the emergency brake on. I can not physically turn the car off when this message appears on the dashboard. I took the vehicle to the service center of the dealer on 11/12/2024. I was told this has been a big problem with gm cars and they have had many cars coming in with the same problem. Currently the part is on backorder, and there is not an eta as to when it will be available due to high demand for this part.

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.

I get a "shift to park" error message even though the car is in the park position as all indicator says it's in park. If I wiggle the shifter it would go away and come back on when I drive it again. On November 1st I came home from work and it would go off at all, I tried everything, wiggling the shifter, put in drive and back in park took if for ride around the block and it still would go off even after 20 minutes. My husband had to remove one of the battery terminal so the battery would die. It did reset it for a few days but now it's back. I reported the issue to the dealer the first time it happen but they can't get me for 3 weeks. This is a hazer if it doesn't go off as I can't lock my car and my husband isn't always with me especially when I go to work.

2021 chevy Trailblazer when I go to park my car, there is a constant error of 'shift to park'. The car is already in park. I must wiggle the shifting knob, restart my car, or drive around before my car will turn off and recognize that it is in park. My safety is compromised each time I get in the car. If the car cannot recognize it is in park, what happens when it can't recognize it is in drive as I am on the road? or reverse? or any gear? my safety is also affected because my car does not realize it is in park, and at times I cannot exit my car. I am highly concerned that the car does not truly know which gear it is in and it compromises not only my safety, but the safety of my family/other passengers, and other drivers on the road. The problem is a known problem and there is an active fix bulletin for the problem. Gm cannot get the part in stock - it has been 5 weeks. It affects not only my year, make, and model, but many others too. Gm continues to sell the cars with this known safety defect. This defect has been confirmed by the dealership, and gm has sent out a known fix for the issue (TSB pit5616a). There is also a class action lawsuit for this specific issue with gm. Gm's solution to me is to trade in my car for a newer model rather than waiting for the part. In addition, many cars of my year, make, and model require a whole new transmission, but gm will only replace the shifter harness to start with, if and when they receive the part. I was told that the part could take up to six months to receive. For an issue that has been happening since at least 2019, this is unacceptable. The only warning that I receive is when I am trying to shut off my car and it will not shut off due to this error. This has been happening to my car for 2 months, but there seems to be a history of this defect since at least 2019.

When I shift into park and turn the engine off a warning signal and bell goes off, telling me to put the car into park, when I have already done so. This has happened three times. 09/30/24 10/14/24 10/2824.

Unknown key keeps getting stuck in the ignition.

Car is not registering when it is not in park. This should be covered under the warranty or a recall as it is a common issue for this vehicle.

The audio in the vehicle goes out the radio and the warning sounds for all the safety alerts. The vehicle has been to the dealer 3 times the problem still is occurring. The problem is random no telling when it will occur. I have called gm customer service they were useless. When the audio for the vehicle goes out when I turn off the vehicle if it sits most of the time the audio will come back on. Today 8/18/2024 the audio went out twice no sounds for anything blinkers, lane assist, side mirror alert, stop alert nothing. This also affects the radio. The service department tells me they are dependent on the gm it guys who in my assessment have no idea how to fix this. This is a safety and hazard problem with all sound going out for all alert systems.

When I shift my vehicle into park and attempt to turn off the car, the computer gives me an error message, "shift to park, " even when the vehicle is securely shifted into park. With this error message engaged, I am unable to turn the vehicle off and lock it. I end up spending several minutes trying to convenience the computer that the car is indeed in park, by shifting it so it registers.

My navigation, radio, internet and onstar went out and continually goes out on a day-by-day basis. I was in a different state, and it was pouring rain, my navigation, radio and onstar ability was gone. Chevy knows this is an ongoing issue with 2024 and said the radio is back ordered. This car is a 2025 and its still and issue. The ability to fix it has been stated as unknown because they have no fix for the radio at this time in either year. When you rely on navigation to get you home and it leaves in torrential rainstorm, and you have no idea how to get home that is bad. If I had been in an accident or god forbid rolled down a hill. Onstar would not have been alerted to this and it could be a potential life or death issue. Everything in the front of the car goes out. I am not sure what else is affected as the car is new and I am learning all the different devices. In all states nationwide it is illegal to hold your device, that is why we rely on this technology. There is no lights or failure indication other than the onstar goes red and the radio goes out. Onstar has stated if my button is red, it's a hardware failure and they will not be alerted, and I will not be able to alert them to an emergency situation.

Shift to park comes on after vehicle is shifted into park and the vehicle is turned off. You have to hit the gear shift or jiggle it to register it is in park or start the vehicle and shift to neutral and back to park and turn it off a few times to get it to register it is in park.

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.

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.

I first noticed an issue about a year ago when an electrical blaring noise was coming from my speakers followed by popping and crackling noises. I have taken my car into the dealership several times without resolution. Since then, I have noticed excessive humidity in the vehicle and recently found the trunk was flooded. I took the vehicle in to the dealership again, and they say the interior fabric is compromised now and the electrical sounds I was experiencing are coming from electrical damage inside the body. I have now read another review online from someone who had the exact same experience with this make and model. I believe this is a safety hazard to drivers who are unknowingly driving around for months in a vehicle that could be flooding and could cause severe damages like in my case. I have documents to support these claims, but I do not have electronic copies. If someone reaches out to me I can provide hard copies.

Intermittently I will receive a dashboard message reading “shift to park” after I park the vehicle and do shift to park. This is a known issue with this vehicle across several years identified as “a known issue caused by a faulty switch in the shifter assembly failing to detect when the car is in park”. Gm has identified and found a solution to this problem by replacing the entire shifter assembly at the owners own cost. This malfunction has the potential to cause great harm. Potentially the vehicle could roll if the engine/system does not identify that it is in park. This could cause very expensive damages or even take a life. The vehicle also remains in accessory mode which drains the battery and can become even more costly for the owner at no fault of their own.

When parking vehicle, warning comes on to place vehicle in park although it already is. Engine will shut off, but dash will not and it continuously dings. This causes the battery to die. This happens every time I drive my Trailblazer and the dealership states there is no quick fix but to continue trying to put it in park repeatedly until alert goes away. Through research gm and chevy vehicles have had this same issue for many years with no recall. I demand a recall as this is a safety issue after being stranded due to battery dying if alert is unable to be cleared with workarounds.
