Mark,
I have a 2020 LTD and experiencing the same MF gate issue. The doors must be slammed in order to latch them and turn off the alarm. One concern is damaging the gates by doing this continually. This thread seems to be addressing non MF gate issues as well, so I was wondering if this MF Gate adjustment needs to be taken to a dealer, or is there an easy DIY fix. I am just west of Grand Rapids, MI., Thank You
