What owners are reporting 3 most recent
I was driving up the road truck cranked up fine started a morning commute, on cruise control the truck instantly out of nowhere lost power completely with no signs of anything and engine won’t attempt to turn over now. I fear the worst has happened which would be catastrophic internal failure for to a faulty engine & its internals.
When accelerating it will over rev and then slip and then punch foward I had a diagnostic did and the sensor in the Transmission aren't working properly and then when just driving my etrak also randomly went out and I can no longer active cruise controll
