When trying to put car in park a "shift to park" notice appears on dashboard not allowing the car to be turned off. It takes multiple attemps be able to get the car into park and turn OFF. This has been an ongoing problem for several years and reported to the dealer. To date the dealer tells me there is nothing wrong with the car. Battery has been changed multiple times.

While driving the temperature gauge drops from normal to cold , the dash displays " steering assist reduced" and the fan is very loud . My mechanic said the thermostat and or sensor needs to be replaced . When he resets with the reader its good for about a week and temperature gauge is normal. After seven days it repeats I only have 40,000 miles on the vehicle and its a 1,400 dollar job. I believe this should be a recall because i have seen a lot of the same complaints in this forum and what about the people who have the same problem but don't complain ?

When I’m driving on the highway, I get a message on my dashboard saying steering assist reduced, drive with care. I have taken to the GMC dealership and they will not cover this repair even though it would be covered for 2021 GMC. When this happens, my car makes a loud noise and my steering wheel does not feel right. I do not feel safe.

Gear shifter is not registering that the vehicle is in park. Because of this issue I have to sit in the vehicle for up to 15 mins trying to get it to register that it is in fact in park and can turn off. If I didn't take the time to do this, it would kill my battery. Unfortunately with the heat index, the vehicle gets hot very quickly and im now worried about getting hot stroke trying to get it to register it is park. This is a known issue with the vehicle that has an active recall for other vin numbers with the same issue.
