NHTSA Complaint #11514786 — 2019 GMC ACADIA

While driving the temperature gauge shuts down completely to C - the check engine light comes on and a message appears on the dash saying "Steering Assist Reduce Drive With Care". Any air conditioning goes from cold to hot and the fan under the hood goes to high automatically and wont shut off. We have been informed that this is a known error that has existed for a long time now, with no recalls to date. I cannot schedule my vehicle for repairs yet because I do not have the money to pay for the repairs. They are saying that the placement of the thermostat and sensor, which need to be replaced in order to fix this problem, are located in a very difficult spot to get to. Saying that it will take upwards of 4-5 hours to get everything fixed, which increases the amount of money to fix this issue. My 2019 GMC Acadia just started doing this about 2 months ago and I have 54000 miles.
