I continue to get a message "Steering assist is reduced drive with care " this appears to be a very common issue with my vehicle model. it is very expensive to fix. I am just outside of warranty so it is not covered. Online indicates this is so common. It is the vehicle thermostat and sensor prematurely going bad

STEERING
"STEERING ASSIST IS REDUCED" This message appears on the instrument panel once in a while, and I have to get a mechanic to reset it. Many other people who drive the 2018 GMC Acadia, are reporting the same problem. This occurs so frequently on this model, that it obviously was a manufacturing design flaw.

SHIFTER PROBLEM 2018 GMC ACADIA. I NEVER RECEIVED A RECALL NOTICE OR BULLETIN ABOUT SHIFT TO PARK SHIFTER PROBLEM

I have owned this vehicle less than 5 years and it has had the "Shift to Park" error 3 times and has now been replaced 3 times. The 2nd time was in August 2023 and yesterday it had to be replaced again. I don't understand how a part can fail this rapidly when the vehicle is only being driven approximately 10,000 miles per year. It only has 82,445 miles. I would like for GM to issue a recall for this issue or advise who the manufacturer is of the Switch part number 84955381 and Harness part number 84733196. The parts are not that expensive but the labor to replace was $ 462.50 and total parts was $ 55.56 on the invoice yesterday. As this is an ongoing issue I would like reimbursement. I am widowed and living on one income.
