I have a very early 2017 Inscription with 12,500 miles on it. I have not had any issues with the engine or really anything else at this point other than the infotainment screen going black on startup once. After restarting the car, it hasn't happened since. That was in the first 14 days of ownership.
If you can duplicate it, take it to the dealer. They should be able to run a diagnostic on it.
Best of luck!
