Does anyone know of a class action filed against Dodge and/or Cummins relating to the 6.7L Cummins diesel? Issues regarding too frequent oil change interval, increasing oil level in crankcase, EGR and DPF issues etc.? I didn't spend $40K to buy a 2012 Cummins engine that calls (as per EVIC) for an oil change every 1500 miles. Then after changing oil finding the oil level rising with lab sampling that indicates fuel contamination. Or, I spend my time and money to go for a highway ride for 45 minutes to passively regenerate a DPF filter. Finally, have a dealership snub it's nose at my reguest to address theses problems. These notions were NOT mentioned to me when I purchased the truck. Anyone follow or share my frustration here??? Thanks!
