Shift to park message in DIC along with audible warning, even though car in park. Will not allow you to lock car, will run down battery. Have to play with shifter to stop. Eventually couldn't get it to stop. Per dealer "Possible intermittent failure of the park switch in transmission shift control. Need to replace transmission shift control assembly." Car out of warranty, cost was $726.21. Dealer said this was an updated part.
The backup grid randomly disappears on the rear view camera when the vehicle is in reverse. This happens at least 1-2 times every trip, and sometimes as often as every other time I put the transmission in reverse.
When auto start/stop turns on the aux pump that pumps coolant into the cabin to continue to heat makes the most annoying sound in the world. GM states that it's normal but, under normal operation you can barely hear the pump. When it malfunctions you can hear it down the block. But sure, that's normal, of course it is. That's why they changed the design of the aux pump for 2020 but won't admit fault. GM refusing to change the aux pump, I had to buy it and do the work myself. Buick warranty is useless.
