What Owners Say
"Egr has been fine. Truck has driven more miles with the check engine light on, than off. Mostly due to the very small tubes that Connect the exhaust sensors to the exhaust system from the turbo back. The tubes clog very quickly after service, including replacement. Have had sensors and tubes replaced numerous times. Not a single problem with the engine or transmission in 212,000 mi. Just the emissions. Particulate filter is regularly causing issues"Russ S., FL (2012 Ram 2500 Laramie 6.7-L 6 Cyl diesel)
"The design of the 2010-2012 Ram Cummins 6.7L engine uses a very large amount of EGR to achieve emissions limits w/o use of DEF/SCR. This creates a soot problem in the EGR system and intake manifold, which caused a malfunction. The malfunction symptoms were: Loss of fuel efficiency, constant DPF regens, engine malfunction codes and engine malfunction light, and very rough running. To remedy the malfunction the EGR system had to be disassembled and soaked in cleaner solution to loosen and rem"Anonymous, TX (2012 Ram 2500 Laramie 6.7-L 6 Cyl diesel)
"Electric sensors for the exhaust system are regularly causing issues. Carbon buildup is the most common. The Chrysler designed emissions are not up to task. Compare to bigger trucks with these same sensors which rarely have issues"Russ S., FL (2012 Ram 2500 Laramie 6.7-L 6 Cyl diesel)
