I have read of a similar issue but have no found a solution to the problem I am experiencing. 2018 2500 CC Cummins started going crazy a couple weeks ago. I started the truck on a Monday morning and had every light on the dash flashing. PARKSENSE UNAVAILABLE, SERVICE ELECTRONIC BRAKING SYSTEM, TPMS, traction control, check engine, etc. all flashing on and off.
Park brake light is on sometimes, occasional low oil or coolant message. My tach and all lower PRND lights will go off and then the truck will not restart for a few hours. Sometimes the tach shuts off and drops to 0 while driving. Once that happens the truck will not recognize the key for a few hours and will not restart during that time. The OBD port keeps shutting on and off so it does no good to connect a scan tool.
Recently the exhaust brake will turn on randomly while driving. Have had zero luck with Local dealership.
46k, bought new, not abused in the slightest.
I just put brand new batteries with no change in symptoms. The truck actually runs just as normal (provided the key registers) but is throwing error codes left and right.
