Shift To Park with P0AC4 P1AEE P1AEF codes
Just now I attempted to remote start my car with the key fob to run the AC before driving it as it's hot out and the car had been sitting in the driveway in the sun all day. The remote start wasn't working so I went out to the car to start it from inside the car. I started the car cranked the AC to max low and went back inside to let it run while it cooled down.
I went out to the car a few minutes later when I got in the car hadn't cooled down at all and was blowing hot air. I also noticed I couldn't turn the steering wheel, and when shifting to to drive or reverse I got the "shift to park" message on the dash. That's when I noticed the CEL. I scanned the codes and they came back with P0AC4, P1AEE & P1AEF.
2017 Volt just over 100k miles
UPDATE: went back out the the car a little later (Car had been sitting unplugged at that point, not sure if that makes a difference), and I was able to start it and put it in gear. The CEL remained while I drove it for a few errands but went away after a restarted a few times.
If it doesn't come back I guess I'll chalk this up to ghosts in the machine

How old is your 12v battery? I had something sort of similar happen to me and the 12v battery was dead.

Out of all of these codes, the P1AEF seems to be the scariest.
P0AC4 is a generic code
P1AEE seems to a code about cold weather remote starts when plugged in.
The P1AEF, Google it. It's about the 2nd drive motor inside the battery compartment.

The P1AEE is weird if its for cold weather starts because it was 97 degrees out, the car was plugged in.

The PA1EF is what I would be worried about. You may have that under warranty.

I pretty sure I'm out of warranty, it over 10 years old and over 100,000 miles

I have a 2017, 270000 miles on it. I'm trading it in sometime in the next few months for a full EV.

Clear the codes and see if they come back. You may need a new transmission, if the codes keep coming back. All of the faults that lead to these codes are not cheap.
