While driving the vehicle, the engine light came on, plus message board said service transmission and the engine went into limp mode. We let the car sit for awhile and checked the car. A scan said it was the pressure solenoid A in the transmission. The car sat for a day and the light was off. Drove the car and then it acted up again and now reverse doesn't work.

Check engine light is coming on, indicating reduced engine power. Took vehicle to GMC dealer and they advised that the repair shop was getting assistance from the GMC Tech line to update a module to correct the issues. I was informed today that the high pressure fuel pump will have to be replaced, along with a hose or pipe to correct the issue. The vehicle has 57k miles on it. Upon researching the issue, I found that this has been a persistent issue with this model vehicle, dating back to 2020. It appears that it has not been resolved and the vehicles could stall or stop at any time. There is currently a class action lawsuit pending on this issue. Please help, this is dangerous

Driving on slightly uphill 55 mph highway, vehicle started jumping & losing engine power. Engine light came on, I made it to the top as it was slowing down. Pulled off to the side. Put it in park for a minute. Message showing on dash read - acceleration power reduced. Drove it on home (engine light stayed on) parked it & had it towed to dealership the next morning. Got a call from dealership the same afternoon saying the vehicle was ready to be picked up. Picked up later in evening from dealership. They left keys & paper in car for pick up. We still tend the paper left it in the box showing we picked it up. The vehicle drove good back home. Drove it the next day, As I was pulling out from a stop sign, it started jumping again for a few seconds. Got home & had my husband to drive it, as we were coming up a small hill, it started jumping & losing power again engine light was blinking at this point. Dash board read engine power reduced. My husband kept on the accelerater & when we got on top of the hill engine light went off & we drove it back to the dealership & left it to be checked again. They kept the vehicle for 7 days & said they were not able to find concern. We picked it up again. Drove it back home without any incident. It has been parked since we got it home.
When accelerating, the engine revved up, switched itself from drive to park, resulting in complete loss of control and the vehicle coming to a sudden stop. The car behind narrowly avoided a rear-end collision by swerving around me. The malfunction indicator light came on for the first time, and the vehicle would not switch out of park. After turning the ignition off and on again, the vehicle would switch out of park. The GMC service inspector ran diagnostics and found fault codes related to the transmission valve components that must be replaced.

The vehicle was taken to a local dealer where the vehicle was diagnosed. The contact was informed that an undisclosed faulty sensor was the cause of the failure.

The manufacturer was not notified of the failure. The approximate failure mileage was 22,000.
I was leaving work when my car had trouble accelerating from stop. The engine revved, but the gear would not engage. It happened several more times after I stopped at a light or slowed to get on the highway. It would take a minute or so to engage, and then I could drive the car, but it made it dangerous when trying to merge on to the highway or to make any turns in to traffic. It then happened two more times as I slowed to make turns until my engine light came on as I was turning on to my street. When I finally made it to my house and put it in reverse to back into my driveway, the car wouldn't move at all. I took it to the GMC dealership because it is still under warranty. The next day when I called, they told me a piston shot through the transmission housing which caused a leak of transmission fluid. There is a GM Customer Satisfaction Program release for 2024 GMC Terrains and Arcadias that all have a defect in the transmission housing, which is causing a leak of transmission fluid. I had noticed that, whenever I slowed to make a turn anywhere prior to the engine light coming on, there was some hesitation when trying to accelerate, but I thought it was the design of the transmission and engine.
