parking or collision sensors are activated in the rain

Collision sensors are activated when rain or snowing and keep a disturbing alarm sound. The service says that sometimes happens.
This happens always in the rain and it takes a long time.
I can not drive in the rain without getting crazy.
What I can do ?

Hmmmm, maybe the sensitivity can be adjusted? No idea what the fix is aside from turning the system off.

That's a common annoying problem. Try to clean them by pressing tissue on each sensor or just wait till they dry out:/

Mines keep malfunctioning when it rains and all winter when it snowed.
