I have the same issue with my 2020 GMC Sierra. Took it to the dealer yesterday and was charged $100 for them to to tell me it was my trailer hitch causing the issue. OK my bad, but when I went to drive away the message appeared on the DIC. The tech who working on it came out and looked at said "it says to see owners manual, there's nothing I can do for you". Very disappointed with the dealership.
