So two weeks ago ABS, Air Bag, Trailer brakes warning message came across screen. Has done it two more times and the last time "service shifter" message also came across. When I shut the truck off to try and reset, the shifter nob wouldn't shift out of Park when I restarted. After letting truck sit for awhile I could shift into drive, A check engine light came on and stayed on. Dealer has scanned it twice now and stated that its losing communication with computer. Appt set for November 27 for service. Its a 22 Tradesman 6,4 Any experience similar issue. Truck only has 8,500 miles on it
