Anyone have updates on the fix/repair for this? My 2020 RST 1500 started to display this message at start up about a month ago. We have had snow in the Chicago area, but I have washed and rinsed the entire truck and underside of the rear bumper and still get the message. Thanks for any help. Truck has 18,000 miles on it and has been into the dealer 5 times now for the rear slider window leak, including being completely replaced after the 3rd visit.
