This video shows the waxed frame on the Sierra (starting at 9:40 mark) . Not a fan of how badly this truck had rusted after only one winter of driving.
I heard on another forum that this issue was resolved, and vehicles/engines built after a certain date shouldn't experience the lifter issues. Does anyone know the date this was addressed and which batch of vehicles was potentially at risk for lifter failure?
I pick mine up tomorrow, it was built after July 5th, 2021 (No steering column lock, no start/stop)
thanks
