Occasionally my temperature setting is at LOW and AC is on full blast

This is a weird problem. 98% of time, when I start my car, temperature setting is at the last setting when I shut off the car. However, ~2% of time, when I start the car, temperature setting is set to LOW and AC is blowing full blast. I have to raise the temperature setting and then AC behaves normally. I can't figure out what causes this to happen. It seems completely random. Anyone else have this sort of problem? My car is 2021 AMG CLS 53.

warranty time!

My guess is the memory for this variable is losing power or bad memory.
one would have to know where last temp is stored and then check the power and memory to that part.
