My truck currently has approximately 112,000 miles. Recently, it suffered a high-pressure CP4 fuel pump failure that sent metal debris throughout the fuel system. The failure has been diagnosed by both an authorized Nissan dealership and an independent diesel repair facility. Both concluded that the fuel system has been contaminated and requires replacement of the high-pressure pump, injectors, fuel rails, fuel lines, and related components. I was driving down the road in Atlanta traffic and on a 2 lane road when my truck all of a sudden started to lose power and stop in the middle of the road. A car behind me had to slam on brakes to avoid running into the back of my truck. There was no warning lights or anything. I was able to push the truck to a nearby gas station to get it out of traffic.

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.

I have owned this vehicle since February 2025 and as of June 2026 the CP4 Fuel pump failed and causes the Cummings engine to shutdown and the vehicle is now immobile. According to recent research and diagnosis, the cost of repair will exceed the value of the vehicle which I am still paying on. It is my understanding that a class action lawsuit for this particular issue is in progress and Nissan is not taking ownership of the faulty part. I now have a vehicle I can’t drive and I own a farm. I used this vehicle for towing and hauling livestock and now this issue is affecting my business. Nissan needs to repair or replace my vehicle given the fact they used substandard parts.

I have owned this vehicle since day one... this was meticulously maintained and serviced regularly. While sitting at an idle, with no prior warning, the vehicle just stopped running. After having diagnosed by a reputable diesel mechanic near me, it was determined that the CP4 fuel pump, known to be faulty in these and other trucks as well had failed. After extensive examination, it resulting in a catastrophic failure of the fuel system, ultimately requiring a $14, 000+ repair. (Unrealistic cost due to the current value of the truck being around $10k - $14k. Metal chards had been distributed all throughout the entire fuel system. This failure is unfortunately very common and Nissan or Cummins should be held accountable for this issue.
