Shifting to park and vehicle stating the vehicle is not in park, won't let me turn the vehicle off. Transmission going out, brought to many shops letting me know that the transmission is not working properly but won't give an engine light if anything is wrong with vehicle, Wont show on readers what is wrong with vehicle. Electrical, Doors will automatically lock and unlock most times lock and locks me in the vehicle having me have to climb through the windows and having to leave my windows open or locks me out the vehicle and can only get in by climbing in the trunk. Testing has been done and brought to GM to figure out the issue, and they replace the computer in it but still has the problem. I have had shops tell me these are all huge issues that needs to have a recall because my vehicle is not the only GMC Acadia that does all this. How is any of this safe for me and my kids.

Sold 2018 GMC Acadia by LEE GMC in auburn. Acadias shift to park was defective, dealership replaced before sale did not disclose, shift to park and transmission malfunctions occurred. I returned Acadia to the dealership several times and they would never properly fix or address my concerns now my vehicle is unsafe to drive. I have documentation to support the claims in my letter, I can send as well if you’d like. Thank you Will send attachment

On July 26, 2024, I was driving my 2018 Acadia, with my cruise control set to 48 in a 45 MHP zone. Nearing a bad curve, I sneezed. When this happened, I tapped the brakes to disengage the cruise control, my passengers side tires exited the road and with both hands on the wheel I tried to slowly bring my tires back to the road. However, I was unable to gain control and totaled the vehicle. A witness stated that she heard a loud pop coming from the vehicle before the wreck happened. I later learned from my insurance that the vehicle had a Recall 17V516000 on it and I was never made aware of it. I believe that this was a factor in me not being able to control the vehicle.

VEHICLE WILL NOT ACKNOWLEDGE THAT IT IS IN PARK. FORCES ELECTRICAL TO STAY ON, AND SOMETIMES WILL NOT ENGAGE PARK SO VEHICLE CAN MOVE AS IF I'M NEUTRAL. HAS THUS FAR HAPPENED WITH VEHICLE STOPPED, BUT YOU CAN SOMETIMES SHUT OFF ENGINE AND EXIT VEHICLE WHEN IT IS NOT IN PARK AND CAN ROLL AGAINST YOU, OR ON KIDS EXITING ETC. VEHICLE ROLLED IN GARAGE AND STRUCK, AND COULD HAVE CRUSHED CHILD AGAINST DOOR.
