The Problem: Anytime a trailer hitch ball is installed it lights up the dash message. Push parking assist switch to off and good to go until you stop at a stop sign and then it comes on again as you drive away. It also comes on at 60MPH driving down the freeway.  Is this normal?  2010 2500HD Z-71.
One other note, if a trailer is hitched up it won't do it. Local Tech support does not have a clue.
