2018 F3L. Purchased new in January 2019. 127 miles from home. Day 8 of a nice road trip. Suddenly the RPM's jumped up to the rev limiter and then I was just coasting along at 70 mph on I35 south of Ames, IA. Almost 100% certain that it's the front sprocket issue. Won't know for sure until next week. My roadside got me off of I35 and a very close friend brought my truck and my trailer and headed south to rescue me. less than 9100 miles on it. 2nd time in the 18 months that I have owned this that it has had to go on a trailer to the dealership because it can not run. B.E.S.T. warranty will cover the repair. But it doesn't make up for the fact that a vehicle with this few miles and this new has issues like this. Just glad it happened close enough to home.
