2019 GMC Acadia

The contact owns a 2019 GMC Acadia. The contact stated that while attempting to park the vehicle, the gear shifter failed to shift into park(P). The vehicle failed to turn off, with the message "Shift to Park" displayed with an audible chime. The contact was forced to move the gear shifter back and forth before it was recognized that the transmission was in park(P). A dealer was notified of the failure and the contact was provided an estimate for the repair. The vehicle was not yet diagnosed or repaired. The manufacturer was not notified of the failure. The failure mileage was approximately 69,000.

My 2019 Acadia often will not turn off because it has a Shift to Park issue. Apparently it is caused by a faulty microswitch in the shifter assembly that fails to signal the Body Control Module when in park, leading to a persistent warning message, inability to turn off the vehicle and battery drain. It has been going on for at least 4 years. It appears there is a recall for this problem but when I search my VIN number a recall does not come up. There are many posts that say "certain" models in years 2017-2019 but why not mine? It is definitely a safety issue because it does not turn off.

Parts # 84733196 Harness ASM-TRAS CONT WRG and 84955379 SWITCH ASM-TRNS CONT have been replaced three times. This is described by dealer as a faulty PARK SWITCH. When this switch fails the vehicle is unable to be shifted to park. Vehicle needed to be located in a level position, wheels chocked and battery disconnected to safely disable the vehicle. Dealership and General Motors has been made aware of problem won't do anything, other that have me pay for the labor and new part to fix it, AGAIN. There is no warning ,it simple decides to fail to shift to park.

Vehicle experiences multiple simultaneous failures including “Steering Assist Reduced / Drive With Care” warning, extremely loud cooling fan operation, temperature gauge not functioning, tire pressure monitoring system failure, and widespread electrical issues (windows, mirrors, infotainment delay). Issues occurred together and are consistent with numerous owner reports for 2019 GMC Acadia models. Condition affects steering assist and engine temperature monitoring, creating a potential safety risk.

My 2019 GMC Acadia has shift to park warning light that repeatedly keeps coming on I've tried to park it have to turn it off two to three times maybe four times I have paperwork that I have went to the dealer and they have fixed it twice with a harness that is failing it only is a temporary band-aid fix. Even though in Indiana we do not have a recall as I know of for this year I would need to have this fixed for my safety I fear that one time it may not go into park and I may not be able to shut my car off.

The contact owns a 2019 GMC Acadia. The contact stated that while driving at an undisclosed speed, the vehicle stalled unexpectedly. There was no warning light illuminated. The vehicle was able to be restarted. The contact also stated that while coming to a stop and attempting to depress the brake pedal, the vehicle lost motive power but unexpectedly lunged forward. There was no warning light illuminated. The vehicle was restarted after the failure. The vehicle was towed to the dealer, where it was diagnosed with transmission failure. The contact was informed that the transmission needed to be replaced. The vehicle was not repaired. The manufacturer was made aware of the failure and referred the contact to the NHTSA Hotline for assistance. The approximate failure mileage was 85,695.

Started getting a warning indication when starting the vehicle that stated some portion of driver assist was not functioning (or some verbiage close to that). We didn't notice any difference in the operation of the vehicle and took it to a service shop after about a week. They did some testing and discovered the problem. I am not mechanical at all but they said there were several technical bulletins from the manufacturer that led them to the problem - a bent pin on one of the rocker arms. I am going to upload the technical bulletins (3) they provided me as well as the invoice (3 pages).
