MS 2014 headlight, battery, frunk failure

This site may earn commission on affiliate links.
Hello,
Yesterday i have experienced a notification showing that right headlight malfunction detected. (the whole thing including blinkers, drl is not working)
Tried rebooting and everything, doesnt fix itself.
Also with the same thing, now i cant open the frunk electronically and i cant preheat the battery to charge it, only able to heat it while driving. Like the preheat on the supercharger doesnt even work. Also the PDC sound is not there anymore but you have the PDC working.
I have had a loose ground nut under the frunk fixed which gave me errors like steering assist failure and etc.
Could this be another ground under the frunk that is loose or?
