They flashed the PCM with S/B 18-018-14 Rev E and added another 2.5 gal of Mopar DEF. I incorrectly assumed they had already accomplished this since it was released as an RRT (Rapid Response Transmittal) in Dec and I specifically asked them to do all the applicable software updates during my last dealer visit.
I spent about 30 minutes recapping the 30+ pages of information I gleaned from this thread along with paper copy's of the applicable Service Bulletins to the Service Manager when I dropped the Jeep off at the dealership. He was sympathetic, but basically said the whole trouble-shooting process has to run its course even if it means multiple trips to the dealer with lots of parts backorder delays.
The good news is I drove it about 150 miles yesterday without issue. I expect I'll be back at the dealership soon, though.
At 38,400 miles another MIL. This time the P20EE code. The dealer now has the new CAT on Backorder. FYI, I copied this article from the ALLPAR website...

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.
