Closing the loop on the erratic trunk opening/closing issues with my R1S.
Rivian Mobile service came to perform routine maintenance and the technician had a replacement trunk button with him.
The original button had a faulty seal. It had taken up some water/salt during our New England...
@jpmc86,
I just encountered the same issue this weekend. The lift gate button has stopped working and the lift gate seems to randomly open without warning.
Was you Liftgate problem solved? What was the fix in the end?
Thanks!
