Reading a lot of these, I'll add my bit. Had my 2016 2500 in for the emissions software update, now the truck does NOT pass smog and therefore the truck can't complete it's DMV reg. OBD is not reading the O2 sensor. Dealer says I need to drive it 1 - 2 K miles. So here we are 2500 miles later, OBD is STILL not reading the O2 sensor. I'd like to know where my share of the 1.6 BILLION settlement dollar is. My cost per mile, and now a trip to DMV to get an extension to my registration should warrant more than a 10% discount on my next oil change. Crap like this does not bode well for future sales of Ram or Cummins.
