Sudden weird problems with GLS550

2017 GLS 550

All of a sudden, 4 problems developed at the same time.

1) Rearview camera stopped working (other 360 cameras OK)
2) Liftgate stopped opening - with rear handle and driver's door button
3) Car will not auto-disengage parking brake when put into D/R
4) Ambient light strip in front dash now flashing yellow. Will not change color and stays on when car is off.

Prior to a week ago, all functioned perfectly.
It coincidentally rained a lot here in the last couple days.

Any ideas what may be going on?

Any resolution of your issues? I have no knowledge to pass on other than this is clearly an electrical/microship problem. I had a similar issue on a brand new BMW X5 right after a car wash. Within hours everything cleared up on its own.

Hope yours has gone back to normal.
