When I turn off the car it says required "shift to park" the car stays on and I can not exit the car it will not lock doors and it stays on.

Due to the failure, the contact was unable to turn off the vehicle. The local dealer was contacted; however, the vehicle was not diagnosed. The contact was informed that the VIN was not under recall.

I’m just reporting several known issues. First, with code P2138, which I got today at Oreilly after my car started throwing warnings. I used my parking brake briefly and afterwards got the following warnings on my car: “Steering Assist is Reduced, Drive with care”, “Engine power reduced” , “Propulsion Power is reduced” , “Service Parking Brake”. I’ve never even had one of these warnings. I’ve only gotten “shift to park” which is another known & common issue. With this P2138 code, it can affect acceleration and essentially loss of control over it, but seems I suddenly have several issues. Recently the infotainment system is possessed, touch screen stops working, it calls people by itself, beeps and scrolls by itself and is essentially useless. Might as well be driving at 1997 something or other, at least I could play a tape or CD. This is Denali trim at 87K miles. Primarily though I’m concerned with this code, if it’s legit, it is very dangerous. How unreliable and unsafe to not know.

As i am driving it flashes the warning sign like if I was going to hit another vehicle when there is no car in front of me, this has happened since I purchase the care 1/2024, this has happen around l7 to 8 times already.

After shifting to park and attempting to turn off my vehicle, I receive an “Action Required Shift to Park” error message. I’m assuming the vehicle is in park but I’m not certain and worry about it moving or rolling. It is difficult to get it to turn off by jiggling the shifter and turning the vehicle on and off. At times, I am not able to get it off and then the vehicle will not lock and the battery goes dead. According to my VIN there is not an active recall but brief internet search states there has been numerous reports, recalls, and lemon law returns due to this.

The vehicle keeps shaking specially at the first and second gear, up to 40miles/hr and at any up hills roads. I took it to the mechanic and he said that it’s an issue in the transmission and needs to be replaced. Also the engine fan randomly turns on automatically, and a warning message stating “Steering assist reduced. Drive with care”
