I'm not a fan of VM motori. I had one in the KJ, and it was crAp. I've heard some hints of the same trouble on YouTube, there's a 1 hour video from a guy who put 100000 miles on the VM motori 3.0 in 1 year. (2015 ram ecodieseI had all the same electrical and coolant issues he had. It locked up at 128000, and I did everything I could to protect it.
