Equipment Problems of Chevrolet Trailblazer - part 1

Vehicle has given me a "shift to park" message when the sift is all the way up and off at park. You basically has to push hard for the message to go away.

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.

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.

Multiple times of getting the warning that I need to "shift into park" when the vehicle is in park. I did have fixed at my local dealer but did have to pay, I know this is been an ongoing issue with many Trailblazer . Chevy should look into recalling the failing part.

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.

The bolts attaching my muffler to my exhaust pipe sheared off of my 30,000 mile 2022 chevy Trailblazer at highway speed, launching them into my muffler. My exhaust pipe dropped-at 70 miles an hour it could have ripped off, and I am lucky the bolts went into my muffler and not something more vital. Also, if the pipe or muffler had fallen, I-or someone behind me- could have run over it causing potential control issues. I am seeing that this is a common problem on various consumer forums. There was no warning- didn't even get a check engine light after the fact- things just got really loud. I was fortunate to be close to an exit (as I was in a construction zone) and was able to get a tow to the nearest dealership.

I get a shift to park warning after putting the car into park. I’m not able to turn the car off, this has drained the battery and caused safety issues for me and my child.

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.

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.
