Highway driving and lost power, started hearing engine rattle. 5.0L Cummins Diesel engine crankshaft is broken. Dealer verified it to be crankshaft. Insurance company denied a claim stating the crankshaft was manufacturer defect. Turns out that defective crankshaft was a known issue with the 2016 and 2017 Titan 5.0L engines that Cummins changed it for subsequent years. This should be a recall. I see daily the same issue on forums and groups in the USA. Thousands of us have a dead truck we are paying for in our yards.
