Two problems related to engine exhaust system have been reported for the 2012 Dodge Ram 2500. The most recently reported issues are listed below.
When driving the truck I will occasionally smell a very strong diesel exhaust odor from the a/c vents in the cabin of the truck, only when fresh air is selected (not recirculate). I have noticed this smell only occurs when coming to a stop, and usually corresponds when the truck is in a regeneration process. The only indicator I have for regeneration is severely decreased fuel mileage the very strong untreated exhaust smell being emitted into the cabin of the truck. After 5 visits to the dealership for attempted warranty repair, the truck still was not repaired and the condition continued. I contacted Chrysler's customer care and to seek resolution and was assigned a case number. In the meanwhile, I was instructed by the dealership to keep the ventilation system in recirculation mode to avoid breathing in the exhaust fumes. Subsequently, after several different conversations with Chrysler customer care staff, I was informed this is a "characteristic" of the vehicle and that I reserved my legal rights to pursue action. Chrysler knows this is a problem, and would rather seek protection from legal settlement or some other means to avoid addressing the problem. I don't think the owners of these vehicles (including myself) should be exposed to untreated exhaust in the cabin of the truck, period. This is a carbon monoxide safety hazard that needs to be reviewed and addressed. Upon research I discoved similar compliants were made to the NHTSA for model years 2010 and 2011. Additional research shows other Ram 2500/3500 owners with the 6. 7 cummins turbo diesel have the same issue. I have documentation of all the dealership visits, all the times/dates and names of the Chrysler employees I spoke with, along with my original complaint sent to Chrysler. Furthermore, I have the research documentation available from other NHTSA compliants.
When driving at slow speeds ( 0 - 45 mph ) or stopped deisel exhaust enters the cab through the air vents due to a leak under the hood. I have been told that this is normal by the dealer and the manufacture's rep. The truck has spent a total of 35 days in the shop so far, with no resolution. I have tried to lemon law the truck but since the dealer refuses to change any parts, I cannot.
