Same here, 2017 as well, Had knocking under load. Truck went into limp mode without previous check engine. Ended up being sludge that clogged the intake actuator?? They are telling me needs engine replacement even though we did 3 engine flushes.I am as well. There is a huge knocking at the top of my engine. My warranty was voided out because I went 7k miles in between an oil change. They said it was too long (2k) mile difference. So my engine is not covered. I have been doing the additives oil change but I feel I may have one year with my 2017 model. Such a shame
Please share your outcome.
