supposedly there is a service bulletin concerning grounding wires. I have a 2014 diesel and had been have the SEL light on and off, then the oil pressure light and various other warning lights. ALSO the issue of it NOT starting one day. I had read on here that someone else had the non start issue and it turned out to be grounding issues. THE DEALERS DONT ALWAY READ THE BULLETINS!!! so after getting the van back to the dealer it was purchased from (they actually drove 150 miles to switch it out) they removed the front facia and removed some ground wires and filed/scuffed the paint off. The paint was causing intermittent grounding.
