Park Assist Blocked

KShi · October 1, 2022

I have a 2019 GMC Sierra 5.3 and every time I get in it the info display says “Park Assist blocked, see owners manual”. I believe this is a common issue. Has anyone had this issue and what did you do to resolve it? I believe this is probably an issue with multiple lines of vehicles. I reset the EMC and it worked for a day but back to same issue after that.

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.
