2021 Chevrolet Trailblazer complaints

Receiving "Shift to Park" alert when vehicle is already in Park.

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.

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 Trailblazer. The contact stated that while the gear shifter was in the park(P), the message “Shift to Park” was displayed. The vehicle was taken to an independent mechanic, who determined that the gear shifter needed to be replaced. The mechanic informed the contact to use the parking brake while parking the vehicle. The contact called the local dealer and was informed that parts were on back order. The vehicle was not diagnosed or repaired. The manufacturer was not contacted. The approximate failure mileage was 16,000.

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.

Reduced engine power, code P0014. Camshaft actuator oil control valve bolt stuck open. All the signs and symptoms per bulletin released by NHSTA to repair if not sold yet. Extremely hazardous when accelerating to get on highway and engine power reduces.

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.

Service power steering light It turns on and off frequently

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.

Unknown key keeps getting stuck in the ignition.

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.

The pick up on the vehicle is losing power it seems not letting the RPM's Go up or drop down before taking off. This cause the vehicle to move slower than normal Code keeps popping up losing power engine while drive and engine light comes on this goes on for about a week or so than stops and engine light disappear and reappears again.

Strong gasoline smell noticed inside and outside vehicle. Took vehicle to dealership 3/1/24 where the smell was confirmed. Fuel rail was found to be leaking. Dealership removed and replaced all components damaged with leak. This problem started again Friday, 8/23/24. Did not resolve and got stronger. Car will be going back to the dealership Monday, 8/26/24 for evaluation.

The contact owns a 2021 Chevrolet Trailblazer. The contact stated while driving at 5–10 MPH, there was an extremely loud clicking and rattling sound coming from the vehicle. The contact stated that there was an unknown object moving inside the vehicle. There were no warning lights illuminated. The vehicle was taken to the local dealer, where it was diagnosed that the turbo needed to be changed. The vehicle was repaired, but the failure recurred. The dealer informed the contact that the sound was duplicated in other similar vehicles and informed the contact that no further action was needed. The manufacturer was not contacted. The failure mileage was approximately 48,482.

My key gets stuck in the ignition almost every time I turn the car off. In order to get it unstuck I have to restart the car, put the car in drive or reverse, put the car back in park and then try to take the key out again. This has to be repeated sometimes as many as 10 times for it to finally release the key. I have read about many other people having this same problem and eventually the key not coming out at all and they've had to have it cut out. I have an appointment at a dealership for August 1st (the first available appointment) and my vehicle is just out of warranty so I'm told I have to pay to have this fixed. This is clearly a manufacturers defect and first starting happening before my vehicle was out of warranty, I just didn't realize that it would become a much bigger issue the longer it kept happening.

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.

I’m just adding confirmation to my solenoid/waste gate/ turbo system reduced engine power on the 2021 trailblazer around 23,000 miles . [XXX] , Raleigh n.c INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

The brake pedal goes to the floor and does not want to stop. There is a brake failure meesage on the dash.

My vehicles check engine light came on at 80,000 miles with a reduced engine power alert. If I'm on the highway I'm unable to accelerate quickly if I needed to. We had the vehicle checked out and it was the Turbocharger that was bad. I had taken it to a Chevrolet dealership and they said other Chevy vehicles have already had a recall on some models for the exact same reason. I believe this is a serious problem with the Trailblazers as well for what I have found online. Please put a recall on this. It's very expensive repair for most people's financial situation.

Turbo failure resulted in loss of engine power. I was driving down the road and the engine light came on and I got a notification that the engine was in reduced power mode. The vehicle became very sluggish and lost speed. While I was fortunate that I was not on a busy road, had the incident happened on the highway it could have been dangerous given my loss of speed. What's of greater concern, this appears to be a common problem on the Trailblazer message boards. The dealer confirmed it was the turbo and stated that the part was on back order. This indicates the problem is occurring very frequently. The vehicle only has 33k miles on it.

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.

Coolant control valve causes car to overheat leaving car and passengers stranded on the side of the road. This is dangerous as it increases the risk accidents. The part is on back order since most of the vehicles with the original part are defective. Something needs to be done to correct this problem!

Malfunctioning door locks cause safety issues for drivers and passengers. If you do an internet search, you can find thousands of questions on this specific issue for Chevrolet door electronics. They are doing nothing to correct this isse.

The Turbo is bad in the car at 90,000 miles. It is a common issue among these, lots of other people have the same issue with the “engine power is reduced” message popping up, per the 2021 Chevrolet TrailBlazer facebook group. There needs to be a recall so they can be fixed. It has happened on mine for the past few months and the dealer said the turbo is bad. The purge pump has already been replaced.

Turbo has went out twice or the piece that makes it go and has been replaced under warranty once and is going in the shop again

On 7/2023, my timing chain broke causing shards of metal to get in the engine. Engine replaced with new engine. When I received car back, started having issues with transmission. Now transmission needs replacing.

Shift to Park warning message continues to appear when already in park and trying to turn the vehicle off. Unable to exit and leave vehicle until you continually try jamming the gear into park over and over to get it to register.

CEL came on at 77,000 miles P1467 Is this covered?

There are no tethering clips at the base of the rear seat to secure a child's car seat. The bottom of the rear seat shows they should be there but the dealer confirms they are not . This is an immediate and dangerous problem and puts any child in a car seat in a chevy trail blazer at risk. Not sure how I'm going to secure the granddaughter's car seat safely .

My issue is with the vehicle's car seat latches. The latches in the Chevy Trailblazer (Manufactured) are designed in a way that is unsafe and also hard to install a car seat for children who are 2 and under or under 40 pounds. Car seat safety is important for all children as it could lead to damages of the head, neck, and or spine. I have installed 4 car seats in my vehicle (Chevy Trailblazer) with it being difficult but overcoming the problem. However, the car seat detaches itself due to the location of the latch (Vertically Slanted). After using the car seat multiple times, it cannot withstand the tension due to the location of the latch which then releases itself from the latch, potentially allowing for more problems to occur and is concerning for the safety of a child. I have, as of now, not have to deal with this problem with other manufacturers like Toyota, Kia, Tesla, Volkswagen, and Honda, where the latch is horizontal. The latch on GMs Vehicles is Vertically Slanted and located left or right of the manufacturers noted car seat latch display/button on the seat. I have only seen the Chevy Trailblazer (My Vehicle) and the GMC Yukon with this problem. I am sure there are others.

Whenever I accelerate over 65 miles per hour the engine and transmission light comes on and the car goes into reduced engine speed. I get a message to service my engine I took it to the dealership, they could not figure out the problem because the engine light only stays on for a day or so and then goes out again. This issue has been happening more frequently over the last few weeks.

The radio screen is constantly going black or glitching, the music will silence, the back up camera will stop working. Carplay does not connect often, also glitches in and out when driving. There is little to no air or heat coming from the floor panel when feet option is pressed for climate. In order to feel heat or A/C have to be on face option.

Shortly after purchase, one of the factory tires had a side bulge. The dealer indicated in their opinion, was from a pot hole. However when they checked the rim, it was not damaged. I had tire replaced. Then at 39K miles, all the the other tires were already getting worn out. I've NEVER had tires wear about pre-40K miles in all my life. At local belle tire, they told me that the Hankook tires that come with new cars are not the same quality as those you would buy at tire store. But I submitted a replacement claim to Hankook, as the belle tire rep suggested, but they would not honor anything. Simply said need tire insurance. I notice when buying the car new, the dealers offer extra (cost) tire insurance. Must be because the are lousy, compared to buying at a local tire store. Now at 42K I'm replacing tires already. New cars should come with same quality tires as you buy at tire stores. And I will tell everyone about poor quality of Hankook brand.

The contact owns a 2021 Chevrolet Trailblazer. The contact stated that while operating the vehicle at night, while reversing the vehicle, the back-up camera image became extremely bright creating a visibility hazard for the driver. The contact stated that the display screen was too bright to see images at the rear of the vehicle. Additionally, while driving at an undisclosed speed, there was an extremely loud audible squealing sound inside the cabin of the vehicle. The contact stated that after a while, the vehicle ceased. The cause of the failure was not yet determined. The manufacturer and local dealer were not notified of the failure. The failure mileage was 32,000.

Very strong gas smells coming from under the hood. After driving a few miles, fumes enter the passenger compartment. Had to stop parking it in our garage for fear of a fire before I could get it into the dealer. I've been told it's a fuel leak associated with the fuel rail system. I'm 20 days past my warranty and only at 29,000 miles. It's a nearly $2000 fix. GM was aware of the problem in 2021 as there is a service bulletin for this item. I should have been notified in 2021 that there was a possible problem which could lead to a fire or explosion.

The car will all of a sudden make a loud popping noise through the radio. It is enough to scare someone while they are driving and have a wreck. The brakes are very touchy to the point of almost giving you whiplash

When putting the vehicle in park I receive a messege saying "shift to park" this means the vehicle is not recognizing I put the vehicle in park. This is a safety issue my truck is not even off when this message pops up. GMc knows about this issue and their is not a recall on it. Dealer will not fix the issue becazue it actually has to say that messege when they are diagnosing the problem. It does it randomly but more frequent now. I call gmc the only thing they can tell me is record it when it does it as a paper trail I guess. They are saying the same thing the dealership is saying they can't diagnose the problem without the shift to park messege. Been having this problem when I hit 20,000 miles

Front wipers spray only on one side, the working side changes, sometimes it only squirts on one side, sometimes it sprays over top the roof of the car, sometimes it doesn't work at all. Reservoir is full, rear window spray nozzles always work properly. I'm unable to wash away debris, in winter with snowy roads it can leave salty/muddy windows. Sap from the trees & pollen create poor visibility. No warning lights are on, never have been. This happened without incident.

Wiper system failed. No function of front wipers. Issue occurred on freeway, in heavy rain conditions, with fast moving traffic surrounding. Visibility with the inability to clear the windshield was at a minimum or not possible. Required pulling over, could have easily caused collision with no forward vision. Vehicle is currently at a dealership for evaluation. Previously brought into dealership, “no problem found” reported by the dealership mechanics. Three separate occurrences of this issue. No other warnings or lights associated.
