Jeep/Ram diesel issues fixed

by Daniel Bennett on

Following the successful launch of the new Cummins Diesel in 2007, the 3.0 VM “EcoDiesels” have been both anticipated and lauded, with the diesel Ram 1500s flying off of dealer lots, and VM planning on doubling its production capacity to meet demand.

However, as with any combination of new technologies, there are often snags once the tires hit the pavement that were unforseen during development and testing.

There has been a spike in warranty failures of catalytic convertors for the diesel Grand Cherokee and, to a lesser degree, the diesel Ram 1500. Current weekly demand for this part is up in the hundreds nationally, a large number given the numbers sold and the length of time they have been on the market. Ram 1500 Diesel catalytic failures, despite the truck’s greater popularity, are coming at just about 50 per week.

The problem did not escape FCA’s attention, and a cause and solution have already been found. Eric Mayne, media relations manager for engineering, safety, and regulatory affairs, wrote:

An SCR [selective catalytic reduction]-related MIL [malfunction indicator light] code was observed on some early-production vehicles in the field. We replaced SCR catalysts in some cases. Other vehicles required only a calibration update.

Our engineering testing and field data show the issue has been corrected, but we continue to monitor vehicle performance, as always, and stand ready to meet the needs of our customers.

Allpar only recently became aware of the problem, which had apparently been addressed before our inquiry. Given the sudden increase in parts demand, however, it may take time for some dealers to get replacements.

Dan Bennett was doomed from the start. His parents bought a 1970 Plymouth Road Runner when it was known that he was coming along, and the rest of the story was written from that point forward.
Raised in a Mopar only home, Dan has also been Mopar only. From ’60s, ’70s, and ’80s muscle to current SRTs of various flavors, Dan has owned, and in many cases raced, each of the Mopar brands.
Dan’s real career is as a “parts guy” at a local dealership, but he also is a muscician, computer geek/gamer, avid reader, and general all around seeker of knowledge. His whole working career has been spent in the parts industry, starting in the aftermarket, and now at the dealership level. He took a couple years off and went in a different direction for a bit as a jewelry designer and salesman, and even though he won a design award for a piece, his true calling, automotive, won out in the end.
He has written articles, or has had vehicles that have appeared in Mopar Muscle, Sport Truck, and Truckin’. In various forums and social media, he has made a name for himself as the “Go-to” guy for tech information for all things Mopar. He also has a large background in many forms of racing and engine building, holding at one point a ASE Certified Master Engine Machinist rating. Though he no longer keeps that certification up to date, he is still very active in the engine building side when he has spare time.
To Dan, there is no option to covering the Mopar world, it is an imperative that must be done to keep his world in balance.
