Cylinder 4-5 which caused catastrophic engine failure. CP4 fuel pump. Crank shaft broken, Metal flakes in oil. Differential service. Was on the road from [XXX] to [XXX] and broke down in [XXX]. Just bought the truck from Lakeland Automall on May 8th and broke down on May 31st. Was in a bad spot to pull over and from what I have gathered we were lucky the Truck didn't catch fire. The problem has been confirmed by the Nissan dealership in [XXX] and also by an independent. As of yet it has not been inspected by the manufacturer, police or insurance representatives. My next call will be to my insurance company for inspection. I was hoping I would be able to fix it on my own by to no avail. No warning lamps or messages before. It started making clanking sounds, we pulled over and then that is when the engine light came on. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

1.The Engine Sub-Harness Assembly failed; melted, I feel due to the engine heat, because this harness insulation is not heat rated and melted off the wire. 2.The dashboard engine light came on and would not go off. 3.The Robbins Nissan Dealership I took my truck to in Humble, Tx. 77338 lied and said this failure was caused by rodent damage; which I know for a fact that my garage is very clean and I've never even seen any signs of rodents. 4.I first noticed a problem approximately in June of 2021 when the dashboard engine light came on and never went off. 5.By this dealership blaming it on rodent damage, this defective harness was not covered by the Nissan North America, Inc. Warranty, so I was charged $1,522.14 for this repair.
