Randomly when the car is out in park a warning light will come up saying to shift into park which is it.
Clicking the shifter will eventually get the code to go away.
Ideas?
There was a warranty repair for this from GM back in 17-18. It should be a no cost repair even if the vehicle is out of warranty. There was a bad shifter position indicator due to a supplier issue. Contact your local GMC dealer.
Crappy gym quality I would assume the transmission module that tells what gear you're in on the transmission is breaking down
It sounds to me like a worn out switch in the gear selector.
I owned a 2017 Acadia, they had a re-design of the shifter latch and electrical sensor. The issue was in a certain vin sequence and was handled without a recall.
