The truck I drive had a Range V8 plugged in and it lost a lifter @32k. Truck is now at 83k no further problems. The 2016 6.2 is now over 200k miles no problems, had AFM turned off via tuner after warranty expired. The other 2017 with the Range has not had any failures. The other 3 trucks still have the AFM active with zero problems, those trucks are from 90-110k mileage.
