Just a bit of advice to fellow XD Cummins owners. I've been on here a long time and I'm a big advocate for these trucks. But If you are getting close to being out of your warranty period, go have your truck inspected by a 3rd party diesel shop. Most specifically, have them thoroughly inspect the turbo for any issues. If there are any issues developing, you need to get the big stuff checked out before something bad happens. My turbo is going bad and needs a total replacement. A completely new one installed at the Dealer is about $7K. At a 3rd party shop, its at least $5K. There are used turbos available on line (thanks to a good amount of bad cranks lol), but if you are keeping the truck long term do you want to replace it with a used part? I have meticulously maintained my truck to a T. Honestly, I'm pretty disappointed in Cummins. Thankfully, my local Nissan dealer is doing me pretty damn good all things considered.
