Transmission Control Value issues. I was driving my car and RPM spiked up high and I coasted and there was no acceleration the rear wheel tires locked up and I felt a jerk. Placed the vehicle in park and pulled hand gear shifter into Drive and the vehicle shifted back into park by itself. Same thing happened on placing the vehicle in reverse. Like the car had a mindset of its own. Luckily I was only going 20 miles per hour this could have been a fatality. This vehicle is not on the recall list. It should be because they use all the same parts.

What owners say
The contact owns a 2020 GMC Acadia. The contact stated while stopped at a traffic light and depressing the accelerator pedal after the light had changed, the vehicle hesitated and then lurched forward. The contact stated that an unknown warning light was illuminated. The contact stated that while driving at an undisclosed speed, the vehicle was vibrating abnormally. The vehicle was taken to an independent mechanic to be diagnosed and it was determined that the transmission needed to be replaced. The vehicle was not repaired. The manufacturer was informed of the failure. The contact researched online but found no recall related to the failure. The failure mileage was approximately 80,000.
Once again (for the second time in a few months) the vehicle put me and my passenger in an extremely dangerous situation. We were driving down a 55mph country highway catching speed, somewhere around 45-50 mph and the car jerked so violently that it shook us even though we had our seat belts on. It then made a weird noise and felt like it was powering down so I stepped on the accelerator to try to bring it back up to speed and it sped up a little bit, jerked again (not as violently) and turned off. Luckily, since it was a country hwy and no cars were coming, I was able to coast into a driveway. I attempted to restart the car to turn around and go home but as soon as i put it in gear, it would shut off. I tried a few times and it would make a "tick tick, tick" sound but not start. I waited a few minutes and tried again and was able to get it to start, go in reverse and get back home. Once I got home it would not start again. Mechanic says it is the same issue and before, which was also part of a recall for this vehicle having to do with the fuel pump relay. I will be trying to tow this vehicle to the dealership for repair.
AUTO STOP enabled while stopped at a stop sign on an uphill incline, there is enough of a delay on restart that it lurches and jerks upon restart, cant be good for transmission and passengers. very much a nusiance.
