Replace the climate control system.
What you'll see
No driver-visible symptom recorded.
System reaction
The climate control system is restarted, without saving any information from the current drive cycle.
Diagnostic depth
Detection

Possible cause
Design flaw in the climate control system software that was not found during its development.
