High Temperatures = KAFAS / Front Radar Sensor Failure

[B-HQC]

Over the past few days temperatures have been up to 45-50 °C (120+ °F) which has resulted in frequent sensor malfunctions, beginning with the KAFAS camera (no collision assist, lane keeping assist) and often ACC suddenly stops working as temperatures increase further up to 50+ °C.

I assume there is no workaround or even any way to reset these system absent a full engine shut off / restart? The systems do start working for a few minutes until it gets hot again and then I get the same malfunctions.
