Vehicle does not recognize it's in park. Vehicle won't shut down completely, it honks horn and beeps inside and won't let you lock doors or restart car. Haven't noticed it rolling away like many people state... jerking the shifter seems to get it working so far.. haven't been stranded yet.vehicle was stationary in a parking lot

First time back in June 10th, 2020, I took it in because of "remote not detected" they could not duplicate the problem, few hours later, same day after I picked the car up it went haywire while parked. It threw itself into theft mode, would not let us manually lock the car, electrical was still on but engine was shut off, alarm, windshield wipers, and lights was going off while I had it towed to the dealership. This time they've told me, the A/C condensation fried the cpu module because the only thing keeping water out of the cpu was a tray. September 9th, 2020 I take it back into the dealership because again the car kept reading "no remote detected". they claimed it was my "dash cam" that caused the issue. October 14th, 2020 the car again went haywire while in motion. This time it threw itself into theft mode, alarm went off, wipers, was reading low fuel (full tank) steering assist turned on and off, brakes started locking mid busy street, steering wheel tightened also. I barely could turn it into a neighborhood street to get off the road. I had the vehicle towed back to the dealership again, through my triple a plan for the second time because I was "out of the area" that they could send a tow truck to. They tell me again condensation got into the cpu and wasn't even sure if it'll happen again if I continue to run the A/C. I picked the car up the next week and on October 25th, 2020 the car again would not read the keys. Every incident but October 25th, 2020 incident, I have let a supervisor from GM know of the situation, his name is [xxx] ext. I have recorded even phone records of every incident that's occurred.

I have experienced issues with the shifter of the vehicle twice now and it has resulted in replacing the shifter at least once. 6 months later and after an initial replacement the shifter has gone out again. The shifter refuses to move out of the park function. Prior to the shifter going out the car would say shift to park even though the car was already placed in park. I believe the issue to be an electrical problem. The middle seat belt in the second row of the vehicle has also stopped working.

My mother has become trapped two times due to the locks on the vehicle not working. The issue only happens when it rains. I took the vehicle to the dealership and they said they replaced some kind mechanism and that everything was good to go. It rained again yesterday and my mother was trapped in the vehicle again. This happens anytime you try to engage the locks, I.e. in park, putting it in park, putting it in drive, using onstar to lock or unlock, using the GMC app to lock or unlock, using either key fob to lock or unlock, trying to lock or unlock it manually.
