To the OP, I was in the same exact boat this past week. I bought a 2016 XD Diesel Platinum Reserve with 69k miles. I was not planning to buy another tuck, but came across this one that looks to be in mint condition and it was $30,152 so I made an impulse buy. This is my second truck with a Cummins Turbo Diesel, the first was a 2014 RAM 2500 Laramie Longhorn. I love the Cummins diesels and the Aisin transmissions are supposed to be bulletproof.
I did a lot of research on this truck before I actually pulled the trigger and the following items caught my eye:
- Oil and fuel filter changer every 10k miles; not a big deal except the RAM was 15k miles.
- Coolant system flush every 45k miles
- Brake and transmission fluid change every 20k miles
- Powertrain warranty ends at 60k miles.
The dealership near me charges is pretty reasonable on the services outside of oil and fuel filters, I do them myself. On Monday, it is going in for a "service reset" on the coolant system flush, brake fluid change, and transmission fluid change. This will run just north of $500.
When I drove the truck home from the dealership, the check engine light came on and warning message came up saying "Reduced Engine Power" and they continue to come up intermittently. When I talked to the Nissan dealership, they said its likely the EGR cooler going out. I conveyed this to the dealership I bought it from and they said to send them the receipt for the diagnostic and repair and they'll reimburse me for it.
These diesel trucks are great, except for the issues with the emission systems. I had a ton of issues with the one on my RAM 2500 and I plan to find someone who can delete it for me. I put around 60k miles/yr on a vehicle and don't have the time to deal with a lot of minor issues with the emission systems.
