The contact owns a 2017 Nissan Titan. The contact stated that while driving at an undisclosed speed, the vehicle lost motive power and was towed to the dealer. The dealer diagnosed that the diesel particulate filter had black sud and the sensor located near the particulate filter had melted into the particulate filter and the particulate filter, sensor, dual turbo, EGR valve and glow plug were all replaced. Reprogramming was done to the vehicle's computer as well. However, the failure recurred and the vehicle could not get out of limp mode. The vehicle was not repaired and remained at the dealer. The manufacturer was made aware of the failure and was awaiting the service record from the dealer. The failure mileage was 48,000.
