I've been using th OME medium setup for 2 years now with no issues,I haul a teardrop trailer and a rooftop tent all summer long and mild offroad/forest service roads.
Most dealer techs are flat rate and retail repairs pay more then warranty repairs (35% on average),unscrupulous techs will try to change everything to retail.Thats why as a shop foreman ive had to write up techs for just this thing,man I hate flat rate!
Sorry to hear you are having dealer woes,if the window not indexing correctly(sits outside the weatherstrip when closed)there is a SSM for that concern
SSM 52470 - Effective April 23, 2024
2021-2024 Bronco - Loss Of Window Initialization
as well for the transmission issue
TSB 24-2042 -...
After a couple creek crossings 2 summers ago and looking under vehicle at home finding sticks jammed up beside transmission went with a PPE pan also,didn't want to add a skid plate under as the cooler is there also.
When I put ARB OME struts in my BD they didn't come with "tophats" so installed new ones all 4 corners,they were different size studs compared to the oem that came on my 21 BD(non sas)Maybe they made them stronger?
