Shift lever to Park Alert on dashboard. Paid to have shift lever replaced on Blazer. Also had same problem on 2018 Malibu..paid myself to have shift lever replaced! I was NEVER NOTIFIED about a Class Action suit. I believe this is a MAJOR PROBLEM on GM vehicle. NEED GM TO HAVE A RECALL!

Steering assist reduced message, then no AC, temp gauge stuck at Cold, P0128 error Code.

Oct 28, 2025

The thermostat is stuck open and needs replaced. If left as it is, could create overheating issues for the engine and even more damage. A service engine light was illuminated prior to finding the issue. The light was accompanied by a warning about assisted steering. Two days after the light first came on, a Chevrolet service department diagnosed the problem and is repairing it. An invoice can be provided at a later date once repairs are completed.

Oct 16, 2025

Nothing necessarily happened, but I've been getting the "steering assist reduced, drive with care" pop up, which assist I've been reading might mean a faulty thermostat. Sounds like a common issue and may e time for a recall? Only 60k miles on my blazer.

My transmission is leaking fluid and has trouble going in reverse. This model Has had two recalls in 2020 and 2021 with the one from 2020 Was specifically for missing parts on the transmission causing leaks. My car is under the mileage for the transmission to even be a problem as stated by multiple mechanics. If there was a recall why wasn’t I informed before the transmission began to leak. The is serviced regularly by dealership where car was purchased. My safety is important to me but I guess not to CHEVROLET BECAUSE I MEVER WAS TOLD ABOUT A POSSIBLE ISSUE WITH THE TRANSMISSION. SO I HOPE YALL TAKE NOTICE AND DO THE RIGHT THING

Warning message flashes "put car in park" after putting it in park and pushing the stop button. It flashes for a few minutes, beeps the horn alert, and you can't lock it . It was diagnosed at a Chevy dealership as needing new switch and jumper harness at almost $800.

Jul 1, 2025

The car does not sense when it is put into park. The alarm continues to ding and the car will not turn off . It displays a message stating shift to park.

Jun 9, 2025

coolant temp gauge stuck on cold, AC quits blowing cold air, reads the thermostat code when check engine light comes on. Was told my car needs a new thermostat and a coolant temp sensor. This has proven to be a common issue among Blazers. there is no rhyme or reason when this happens and will fix itself after a while, but then happens again.

May 20, 2025

My check engine light is on the, the temperature meter is stuck on cold, the A/C only blows hot air, and the engine fan is blaring loud as heck the moment the car is started. Also it keeps telling me the steering assist has failed. I have replaced the battery and checked the coolant. Still the same issues.

May 6, 2025

"shift to park" message appears when parked (even if safety brake is engaged) and attempting to turn off the vehicle. The vehicle does not turn off and remains running for various periods of time. Unable to turn the vehicle off, leaving it unsecure and drains the battery. This happens consistently. I contacted my local dealership and they confirmed getting several of these reports through their shop, but no recall has been made.

Apr 28, 2025

My check engine light came on (solid) and my AC stopped blowing cold air and my auto start stopped working. I used a diagnostic tool to read the code and it said "P0128 Coolant Thermostat $07e8". The same thing happens with my heat when it gets too cold out.

Apr 22, 2025

Action Required: Steering Assist is Reduced Drive with Care & Check Engine Light comes on after the alert message. When these are on, the ac does not get cold. Unhooking the battery resets it for a few days and then it comes back on.

Apr 5, 2025

Thermostat clicking off, internal cab thermostat not reading going to C, and air blows hot

Mar 19, 2025

Consistent Blazer issue. Error coded “steering assist reduced. Please drive with care”. There is a thermostat issue. Causing the car to sputter and not run properly. This a common issue with Blazers and a manufacturer default. Should be recalled and covered. It is a safety issue.

Mar 19, 2025

Steering assist is reduced driver with care

Mar 17, 2025

Steer assist and thermostat issue. The vehicle has 42,000 miles on it. Have not been able to obtain/find a new thermostat since November 2024.

I am having a problem when I shift my car into Park to stop the car It will shut the engine off, but it will not shut off the accessories, and I have to restart the car and tried over and over again until it shuts off. Also the dash lights up to shift the car to park, but I already have

Yesterday I received a message saying Driver assist reduced. Today received the same message, and heard a whirring noise when car was started.

Nov 6, 2024

My 2019 Blazer gave a Steering Assist warning on 2 Nov 2024. I was aware of a recall for other Blazers but for some reason my VIN was not among those recalled. I took it to the dealership on 6 Nov 2024. The dealership has determined that the issue is indeed the same issue with those other Blazers that have been recalled but refuses to include my car in the recall because the VIN number wasn't originally among that recall. I was told that the car needed anew temperature gage and that they would have to order it, however, the component was available outside of the dealership. I paid for the diagnostics and the part, being told that the light(s) would stay on, I would still be able to drive it and that I would receive a call when the part came in. It is my understanding that the steering assist reduced can affect the power steering and essentially revert back to manual power steering, potentially causing a loss of control while driving and increasing the risk of accidents. There were no warnings of the steering failure assist warning. It just appeared on Nov 2, 2024 at 1130am. About 1240pm I noticed that the temp gage was inop and the check engine light was now illuminated. I contend that because GM has already identified the thermostat issue serious enough to do a recall, then all Blazers with that recall issue, VIN number aside, should be given the same consideration and not have to pay for something that GM has already taken responsibility for. The dealership however does not agree for the simple fact that the VIN was not identified in the original recall.

When I shift my car into park, I’m getting a “Shift into Park” warning on the dashboard and alarm is sounded telling me the car is not in park while it is. The car won’t shut off.

Sep 24, 2024

The vehicle is not recognizing the car is in PARK when it is placed in Park.

Sep 5, 2024

When I am shifting my vehicle to park (gear shift in console area) and turn my vehicle off I will get an error code in my dashboard that I need to shift to park. My gear shift in the console is lite up P and my dashboard electronic system says P; but when I try to turn my car off it won't turn off and stays on again giving me the error code that need to shift to park. I then have to turn my car back on to then try and turn it off with the same error code coming on. I can try pushing the gear shift further with no success, shift to different gears back to park, and try waiting a few minutes after shifting to park before turning it off and still no success. This is a safety issue that my car is not really in park and will take off if I take my foot off the brake when this is all occurring. I at one point had to turn my vehicle on and back off with no success at least 5 times before I can finally get it to turn off. This problem has been confirmed by multiple Chevrolet dealerships with all of them saying they have seen many vehicles (same make and model with other models included) with this issue. Manufacturer knows about it.

When I stop and put my vehicle in park the panel lights up and says put car in park and it is in park. I am not able to shut off my car when this does that. There have been recalls on the 2019 blazers for this specific reason. Mine did not make the cut. I had to pay $400.00 to get this fixed from the Chevrolet dealership and it's the same thing that has been happening for the other 2019 Blazers that had recalls. I would like to be reimbursed. Thank you

Aug 11, 2024

We had the shift to park issue 3 years ago and fixed it. Cost near $300. Now we are taking it back in for the same exact issue. In addition to this issue all the lights on the dash board keep coming sporadically and on star sent us report with a ton of engine and transmission issues.

Jul 19, 2024

2019 Chevy Blazer RS - 39,217 miles and shifter assembly is malfunctioning and will not allow car to turn off properly and leaving lights, beeping and miscellaneous dash indicators on. This is a known issue with Chevy.

Jun 6, 2024

When in park my car says “shift to park” when it has clearly been shifted into park. I’ve read forums and it’s the same issue for many Chevrolet cars

May 11, 2024

There were 2 incidents. 1) got a steering control error, plus my AC stopped working and the temperature gauge would exceed zero. I was able to drive. I had the error code reset and the problem went away 2) car stalled on a busy street and I got a service all wheel drive warning. I was able to restart the car and the error went away.

Shift to park when the car is in park notice

Feb 25, 2024

I'm getting a Shift to Park message on my dashboard when the car is in park position telling me to take action with a loud dinging sound. I need to know if this is a GM issue? Thanks

Feb 16, 2024

When shifting into Park, system fails to detect that car is in park and gives the Alert/Error message informing driver to “Shift to Park”. This error prevents the car from turning off or locking. Further, driver is unable to differentiate between if the car is actual in park or not, which is a major safety issue. A car not recognizing being in Park, can pose a huge risk to the driver and any around the car when it is in this state.

Right before my warranty went off I had my car in for service. I also mentioned the shift to park light coming on after putting my car in park. They could not duplicate the problem. On the next service I mentioned it was happening more and more. They wanted to charge me a minimum of $500 just to look at it but also informed me it was a known issue. Because my warranty was now expired by a few hundred miles they wanted me pay if I wanted them to look. Absolutely not. Known issue with hundreds of the same complaint=‘s RECALL Fix our cars Chevy!!!

When I placed my car in park, I received a SHIFT TO PARK warning. I was unable to shut the car off. I had to return home because I was unable to leave my car. Upon returning home, I was still unable to turn off my car. I had to keep restarting, going in reverse, back in drive, then to park. Kept receiving the message for over an hour. I was trapped in my car, unable to turn it off or lock it. Took it to dealership and they are aware of the problem, but no recall has been issued. How can this be legal?? I had to repair the car due to the fact that I felt unsafe to go any where. My bumper to bumper expired in 2022 and this is not covered on the 6 year warranty. My car only has 37,196 miles. Is there anything you can do? Also if a recall is issued, will I be notified?

Nov 3, 2023

Shift to park will not disengage even though the car is in park. The alert will not stop sounding. Additionally, the radio and car will remain on and doors will not lock.

I leased this car October 2019 and I had to tow the car to the dealership on December 12, 2019 for an electrical issue, as the car would not start. In June 2023 with 35,700 miles, I was driving the car when an error messages flashed on the dashboard. First message was to put the car in shift/neutral and immediately I was unable to move the shifter, the break got hard under my foot and the car "STOPPED IN THE MIDDLE OF THE ROAD". Then it kept flashing the following messages "SERVICE ESC" and "INFORMATION - ALL WHEEL DRIVE OFF" and the starter light remained "GREEN". I towed the car to the dealership, however, it took them a week to check the car and as a result the battery died and they missed the "Error Messages and CODES". Without the accurate codes, I was told I had to replace the battery and starter. When I picked up the car the air condition wasn't working, so I had to replace the compressor!!! I was very afraid to drive the car and I had it parked at home for some time. My husband and friends kept encouraging me to drive it etc. Eventually, I gave in and I started to drive the car, but still stressed and afraid and praying the car will not shut off again. The trauma of the car stopping so suddenly in the middle of the road and there was nothing I could have done - is very SCARY. I am just thankful that I was not on a highway when this happened - I could have been killed. However, I decided to drive the car and I now have 38,119 miles on the car. I had to take it to the dealership again on October 24, 2023, as when I park the car, although the shifter is in Park, the dashboard is telling me to put in in park and the Starter button will not turn off. I was advised by the dealership that I need to change the "Shifter Assembly" No one can tell me why the car stopped while driving in the middle of the road and I do not feel safe in this car anymore. I am just changing all the parts in this car one by one!!!

Two days ago I received an alert that says steering assistant reduced drive with caution then I noticed my temperature gage was all the way on cold and my a/c doesn't blow cold. My fan on the radiator blows constantly and doesn't turn off I was reading the chevy blazer forum and it seems to be a numerous amount of people with the same exact issue dating up to 4 days ago I do not see a fix for this issue. People have replaced sensors and thermostat but that does not seem to fix there issue I feel as though this is a known issue with no fix yet. Please I need some help here my warranty just ran out and I don't have $1000 to replace parts and this is my only vehicle and still owe $33,547

Hi My wife arrived home from work and put the truck in park. A message came up on the instrument panel saying shift to park and would not let her shut the vehicle off. I went out could not figure out what was going on because the truck was clearly in park. After moving the gear shift around the message went away and I was able to shut off the truck. A couple of days later when she got to work, it did it again. Moving the gear shift around turned it off. I took the truck to the dealer 10/18/23 and inquired about a recall for this because so many people are having the same issue, on several GM makes. No recall and I had to pay close to $572.99 for them to replace the gear shift assembly. We just bought the truck in Feb of 23 and paid cash. $30.000. At time of purchase the truck had 21000 miles. Today it has only 24000.

Can will not turn off. States shift into park when the car is in park

Jul 24, 2023

I looked online and a lot of Chevy products are having this issue. Something will pop up saying limited driving assistance then your cold hot gauge doesn’t work is get stuck your air conditioning quits working your oil gauge quit working your battery how much voltage you have quits working it falls your whole window up where you can’t see. This is an ongoing issue with most of GMC vehicles, especially blazers. This is a safety issue that could cause your car to blow up or your windows. The fog over where you can’t see and you have a wreck and I could kill you.

When Driving the vehicle, usually around 1500 rpm, you feel the transmission start to stutter, and during this stuttering, the whole car shakes violently. this violent shaking occurs on the highway with speeds of 70mph and over. the shaking causes the steering wheel and lane centering function to become disoriented, hence almost causing me to get into an accident on the highway. This is not an isolated incident for my vehicle only. I am in a chevy 2019 blazer group on facebook and dozens of members have experienced this same exact issue. the members that got it repaired had to have the entire transmission replaced. apparently it is an issue with the gears not fitting properly and grinding causing shavings to get into the the transmission fluid causing the danger. I have addressed this issue with the chevy dealership i bought it from but the refused to document it or take accountability for the issue.

Steering assistance reduced drive with care! Will not let engine warm up. GMC does not know what is causing this to million of cars. Could evently blow engine and or cause a fatal wreck

I have had problems with my 2019 chevrolet blazer since I bought it. Incidents as follows: computer screen stated fuck off...took car to dealership and I was told they never saw anything like that. They suggested to set back to manufacturer radiodefault. SD card has been removed is what the vehicle was telling me . Took to dealer,I was told they could set radio back to factory settings...On star was not on star,at one point I said to on star ...you are lying you are not really on star and the person on the other end laughed I have many police reports about this issue. Continental tire burst, so I replaced tire not knowing what caused this incident.I replaced with another continental tire.car bucks sometimes when shifting...took to dealer , I was told because of incline, there are no hills mountains or anything like this where I live.when I turn the car off a bell will sound...and displays shift to park...I am in park,so I will have to turn car off and restart 5 or 6 times. I have issue after issue since I purchased this vehicle in 2019 off the showroom floor .and today's date is 11-10-22 Also rear camera will come on when the vehicle is turned off this has been an ongoing problem. An app was downloaded on my vehicles computer, called manufacturer and I asked if a satellite flewover my my vehicle because the app was not on the screen before.she stated she never heard of that. An app on my computer screen was deleted as I sat in the car looking at the screen.

The TBS sensor or switch that tells the vehicle when it has been put in park is malfunctioning. It is not allowing me to park the vehicle correctly and forcing me to start and stop the car multiple times before registering that it is in park. Also, while driving it causes the doors to lock or unlock due to sensing the vehicle is in park or not. To my knowledge this is a widespread issue with GM from 2013-2020. The vehicle has less than 70,000 miles and should not be creating a safety concern for my wife or baby. This needs to be looked into and fixed via a recall. The consumer should not have to pay for the cheap part GM used and should not be failing within 3 years of purchasing the vehicle.

Feb 21, 2022

When placing the vehicle in park and turning off the vehicle there is a message on the dashboard saying ‘shift to park’ and the vehicle will not shut off, and you cannot lock the vehicle due to the error message.
