When I go to put my car in park, I get a notice warning chime to shift it into park. Which then results me into not being able to turn off my car. I am then forced to sit in the car and try to wiggle the shifter until it registers that the car itself is in park.. This first happened to me a few days ago with my toddler and infant child in the car. Compromising my safety as well as the safety of my children, since I was now forced to sit in a public parking lot with my kids in the car trying to not only turn off the car, but also trying to make sure my car was properly parked and not an endangerment to others. I recently called a dealership on feb26,2025 and found out I had the problem fixed once before in 2021. I-??m now currently working on getting my car to the dealer to get this issue resolved asap. Which is an inconvenience to me, my schedule as well as the schedule of others, since I now need assistance getting to and from the dealer along with taking my children to school and or appointments.

When attempting to put my car in PARK, the car issues a warning stating the car is not in PARK, it doesn't recognize the gear shift being in park, therefore, I am unable to shut my car off or lock it up. It is a known manufacturing defect and GM refuses to cover the cost to add a bandaid to it as there is no permanent fix. This is a safety issue, and now my car is not reliable, nor safe. GM refuses to issue a recall on this.

Shift to park message coming up on dash screen eventhough shifter was in park. Engine would not turn off. Had to shift several times for vehicle to recognize park. There was a recall on some 2019 Chevy Blazer and a technical service bulletin issued, but my VIN number is not on the recall list. The current mileage is 37752. I bought the vehicle new. Dealership relaced shifter control at a cost to me of $553.60. If there is a safety issue, should a recall cover all ?

Park to shift code displays, would be available for inspection. Problem has been confirmed by dealership-bill roberts Chevy in bolivar, mo safety issues- not for sure if car is in park could roll off. Will run battery down. Safety issues with existing the vehicle. At some point could cause transmission failure. Problem started around [xxx] mileage on vehicle is 44,000 not under warrenty due to mileage the dealership states. GM and dealership stated that my VIN# is not under the recall for the very same thing as on other VIN# with this same problem. There is a problem if my car is doing the same thing, it should be covered under the recall as well. It is a safeety issue that the company should cover.

2019 Blazer with 73,399 miles is in Park, but displays "Shift to Park". System does not recognize that the vehicle is in Park. Vehicle will not turn off even after shifting transmission to drive and then to Park again. "Shift to Park" message won't reset. Dealership said it's $1,642 to fix issue. Afraid to drive the vehicle because it won't shut off, can't be locked, and will run out of gas/battery if "Shift to Park" displayed message can't be reset/fixed.

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.

8 out of 10 times I put the vehicle in park I receive a "shift to park" alert. I have to put it in another gear several times before it recognizes it is parked. Sometimes flicking the shifter push-in piece on the bottom will work. I am unsure if the car is officially parked when I don't get this message.

Could lead to a crash if steering is restricted due to P0128 code was repeatedly triggered as a fault code. Turned out to be thermostat which is being replaced on thousands of these vehicles. You can search for the message. GM is replacing under powertrain warranty however many vehicles are beyond warranty. This is approximately a $1000 repair.

I cannot shut off my vehicle. When I turn off engine warning message and alert binging tells me to shift to park. The vehicle is in park but vehicle does not register that it-??s in park. I-??m stuck in vehicle which will not stop alerts and runs down battery. This is a hazardous situation. I can-??t tell if car is actually engaged in park or not. This started happening intermittently over the last month but now it happens 8 times out of 10 when I try to shut off the vehicle.

Error code P0128. Engine temp sensor keeps going off and on. Temp gauge drops to 0 and doesn-??t read, AC goes out, check engine light comes on, steering assist is reduced drive with care notification comes up. This error code and same issue is all over GM forums. Thousands are experiencing this same issue, having to spend over $1000 to get it fixed. Ridiculous this isn-??t a recall yet.

I took my vehicle to the dealership for the recommended oil change on 09/15/2023. I am extremely good about keeping up on the routine maintenance. Upon arrival, the technician asked if I knew that my check engine light was on. I stated no, it was not on during my drive in and has not been on previously whatsoever. I scheduled a diagnostic for 09/20/2023 and brought it back to the dealership with 68,191 being the mileage. It was determined that my thermostat needs to be replaced. I then began receiving the message Steering Assist is Reduced" which is very unsettling. I am finding that a lot of newer model 2019+ Chevy Blazer owners are struggling with the exact same temperature issue, even those with way fewer mileage than mine for example a person who just had 25K on theirs. This needs to be taken more seriously / addressed further by the manufacturer.
