Electrical Issues
Yesterday morning I started up my car expecting to have a normal commute, but immediately upon startup I knew something was wrong. Lights on the dash were displayed, and the screen in the middle of the speedometer was displaying that the airbag module was inoperative, along with a host of other things like parktronic, lane keeping assist, ESP, and traction control. The radiator fan was blowing at full steam as well, which is odd since it was a cold start. The gear selector was also stuck in Park.
I hit the start/stop button to shut the car down, but the car wouldn't turn off no matter how many times I hit that button. So I popped off the start/stop button and inserted my key to shut the car down. After waiting a few minutes I cranked the key to turn the car on and the same issues presented themselves again. Tried to start the car again about 4-5 times with 5 minute intervals in between each attempt, and when the same result kept presenting itself I called roadside assistance to have the car towed to the nearest dealership. SA told me that the they were slammed, so after a day of them having the vehicle I got a call today telling me that the car is acting normally with none of the above issues being present.
I searched the forums and couldn't find anything similar happening to anyone else, so wanted to ask if anyone has any idea of what the issue could be or if they had something similar happen before. Thanks in advance.

The times that I have had issues anywhere nearly like this involved the battery. Our cars kill batteries, and there isnt much warning, as is typical for AGM type. My car did weird things as it just did not have the voltage to run all systems properly.

Not to jinx myself, but the battery in my C43 lasted over a decade; I never replaced it. My C63 battery is 7 years old. Today, however, I got that "esp, etc. inoperative" thing with dead power steering for the first time. Restarted it and it hasn't returned. I thought maybe it was dirty wheel sensors since I haven't washed my car in many months, so I sprayed down the brakes the best I could (i know I probably didn't reach the sensors all the way).

Another thing that can cause similar warning lights is the steering input sensors being out of whack. The cure for that is to crank the wheel fully side to side and back three times, then restart.
