Anybody else with this issue - Have a 2019 1500 Limited that has every option that was available. Issues started with the driver's door - when opening the interior lights flicker, running board will not deploy or will rock back and forth and the center display will not shut off. No issues with any other door. Then shortly after the truck would not start. It does recognize the key fob as it lights up the driver's cluster when pushing start. The system looks like it goes through a full system's diagnostic sequence. All the individual systems cycle through the driver's display and report "inop". This includes Lane Departure, Adaptive Cruise, Air Ride Suspension, Auto Headlight fail, Windshield wipers go for 4 to 5 sweeps ...etc.... Letting truck sit for an hour or so then it starts but looks like it is in a get home mode.... No Cruise, Suspension full up, Lane Departure off ... ect... and unable to control any functions. After home, let truck set overnight and next day starts fine with no faults and everything works. This happened twice on both very cold and very warm days. After second event, took it to several local Auto Parts stores and scanner would not communicate with truck. Ran it over to the Dealer after two weeks in the shop, they "fixed" a broken wire above the scanner receptacle. This fix did not fix anything. As soon as I got the truck back the driver's door - flickering lights - running board issues were still there. Shortly thereafter I had the same non-start - diagnostic event again and it cleared itself after sitting for several hours. Two weeks ago it cam back again but this time sitting does not reset it. So had it towed to the dealer two weeks ago and there is still sits.
What has been done:
After 2nd event Dealer "fixed" broken wire above Scanner receptacle - no change to anything
Now:
Dealer reports Scanner shows "multiple Computer Disconnects"
Tech says there is a wiring issue near the driver's door in the cab but unable to locate the exact defect
Dealer said may have to remove the entire contents of the cab to replace the complete one-piece cab harness - seats, dash, sidewalls, headliner etc.....
My question:
Has anyone seen this issue or have experience enough to steer this sequence of failures to a logical cause?
