As described, I've had the same issue (2019 Ram 1500 Big Horn): Park assist (front and rear), service shifter and oddly, the autocorrect shifter error. Errors are intermittent not consistent. However, codes I've received indicate a network communication error. As a matter of history, I did replace the 3rd brake light as indicated in the extended warranty, but under closer examination noted a leak in the back window (both "t's" on the window frame leaking water; clearly another issue Ram should be aware of - several YouTube videos of the same issue). Has anyone had any success submitting damage subsequent to the faulty brake light which allowed water intrusion (potentially impacting the RF module)? The warranty extension seems to acknowledge break lights are leaking water into the cab. Reasonably, said water leak would also potentially compromise the interior components including but not limited to modules (i.e. RF module located behind the backseat).
