Just curious... Has anyone with AP1/MCU2 and recent software had issues with the frunk not opening with the key fob? The fob still works for other functions, and the frunk unlocks from the screen.
I did have a problem with one of my fobs after I accidentally washed it. I found it in the dryer.
Initially it worked to open the rear hatch, but nothing else. I let it sit with the battery out for a few days and tried again. This time it worked and it has worked fine since.
Yours probably didn't go through the wash.
