I have a 2016 Platinum Reserve diesel XD with 63k miles. Last Thursday I noticed that the motor sounded louder than normal (almost a rattle) the next day I was towing a 19 ft scissor lift home from an electrical job I was doing and the rattle got louder and louder. About half way to my shop (15 miles) the truck went into reduced engine power mode. 5 miles later the trucked locked up and shut off and sounded horribly loud. I was able to get pulled into a gas station and had it towed to the Nissan dealership here. 3 days later they call me and told me I have to have a new motor. They said aren’t 100 % sure what happened. Fortunately they called yesterday and said the motor is covered under warranty.
