2014 Palazzo with 85,000 miles over almost 4 years and never any issue with DEF or DPF, but only a replacement of one of the emission NoX sensors back in late '16.

I've seen the 'engine light'(outline of engine only, no words) come on, which is really a misnomer since it is actually an 'emissions' alert - nothing to do with the engine, though it's unnerving regardless.
This happened in the aforementioned emissions sensor issue, but I drove on for over 1,000 miles before the replacement, per Cummins instructions. Also, no cost to replace since Cummins emmissions warranty is for 5 years.

The only other instance was after allowing the DEF tank to fall below 1/4, which can also assert the same alert. After adding DEF, the alert went off on it's on after several stops/starts of the engine.
