I bought this unit at in September 2020.  The problem is with the Lower Panel Guides.  They are cheap black plastic and break very easily.  These parts are supposed to help support an 80 lb. unit.  That is kind of scary.  Unfortunately I cannot find replacement parts for these from LG or their preferred parts suppliers.  I will have to find a way to make replacement parts on my own.  Very dissatisfied with the construction of the unit.
