There is a fleetwide problem with the DEF system in these vehicles that is well known to the manufacturer yet they have failed to address it. The system frequently produces a DEF error which causes the vehicle to go into a shutdown mode, which can leave the occupant stranded in a dangerous situation.

There needs to be a firmware update to the transmission shift logic or at the very least if a door is sensed as open automatically place vehicle in park. Backstory....I've owned this vehicle for 2+ years and have mistakenly placed the vehicle in reverse (via the Dodge Ram style prndl selector). When this happens I usually catch it before I exit the vehicle. Admittedly it has happened and I've almost been run over by my own car. This is a hugely dangerous issue.
