On July 1st, 2023, I purchased a 2024 Chevrolet Silverado 2500 from Orielly Chevrolet in Tucson, Arizona. On July 2nd, 2023, an error message popped up on the dash, “Park Assist Blocked See Owner’s Manual”. It continued to happen on and off til this very day.

I kept getting “check trailer wiring” messages followed by a “trailer disconnected” message while towing a trailer and the trailer brakes would not engage. The trailer would “reconnect” and then “disconnect” constantly while driving. I lost my trailer brakes while trying to brake down a hill. Not having working trailer brakes is extremely dangerous.
