The car has parking brake on unable to disable.Have to put in drive force the system to move. Same with reversing the car. Air bags not working. Seat belt restraint on when we are wearing them. Left turn signal failure. Steering limited caution sign on. ESC sign on. Engine light on. Transmission unable to shift soon light on. Traction lights on. ABS brake light on. Temp says -40 degree when 30 out. I-??m finding this unsafe to drive. Call GMC that told me to start On Star diagnostic. Pull up at least 4 codes And today the transmission indicators came on. Not sure what to do. The car has low miles. But I have stopped driving as of today due to break down or serious malfunction while driving.

While in motion- blind spot sensors turn on when they should not and vice versa. Traction control has failed multiple times while driving. Predictive braking has activated improperly multiple times while driving. Cameras went out and then battery completely died. Was told fixing battery would fix vehicle. This has proven to be untrue. Vehicle is currently in for service for third time. Remains under warranty, as I have had it three months. Most recent date has been used but I've had problems since literally the first full day I have had it.

Recently purchased a 2020 Acadia denali. When parking at any incline the parking brake automatically turns on. Dealer is not sure why, but no where in the manual does it state this is normal. To disengage brake vehicle has to be put in gear with foot on brake to turn off. The parking brake should turn off when vehicle is in park with foot on brake but it does not. Dealer is unsure of issue and has an open case with GMC to investigate.
