I have an intermittent issue with my 2019 Laramie Longhorn with 117k miles. About 10 % of the time, the slide-out step does not engage instantly when I open my door from the outside. I have to wait up to 10 seconds before it extends. Also, when exiting, I turn off the engine and open the door, the dash is still lit, the radio is still on, and the step has not extended. I'll have to wait up to 10 seconds for everything to work properly. I took it to the dealer, and I could duplicate the issue. No error codes have been stored when scanned. Has anyone else had this issue? Any suggestions on how to correct the problem? Any guidance would be much appreciated...
