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.

Received repeated message on display " steering assist reduced, drive with care" Engine races at times and Auto Stop quicks working. 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.
