My 2019 2500 w 12” Nav went into the dealer a few weeks ago with a crazy CAN bus problem. 12” display kept going blank, “Blind Sport Alert Temporarily Unavailable” in the dash display, loss of control of windows and mirrors. I took it in to the dealer and it was doing all this while he read the codes. Showed multiple CAN bus problems. Kept the truck for a day and drove it for 105 miles, could not duplicate, handed it back to me, said they did nothing. Today it started again with the “Blind Sport Alert Unavailable,” loss of mirror control, and now the seat heaters and steering wheel heater will not turn on. Also I can force the “Blind Sport Alert Unavailable” to annunciate by moving the driver seat in any direction. Anyone seen anything like this?
@RamCares ? Could it be loose connectors under the seat? Wondering if I should have not paid for all the fancy technology...
