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.

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 am submitting this complaint on behalf of the vehicle owner. On March 31, 2025 (136,962 miles), the vehicle was brought to Fred Anderson Nissan of [XXX] for Voluntary Emission Recall PD128 (NTB24-061), which required a new Particulate Matter Sensor and ECM reprogramming. One day later, the Check Engine Light illuminated. On April 2, 2025 (137,083 miles), the dealer diagnosed code P2002-00 (DPF Efficiency Below Specs). Repair Order #XXX states: "The new sensor that is now monitoring DPF is able to see this and is setting the code as designed." The dealer's own documentation confirms the fault code was triggered by the recall — not a pre-existing failure. The vehicle had no warning lights before the recall was performed. Nissan Consumer Affairs (Case #XXX) declined goodwill assistance citing mileage, without addressing the documented causal link between the recall and the fault code. The owner now faces a DPF replacement costing several thousand dollars as a direct result of complying with a manufacturer recall. Safety concern: A DPF in confirmed fault condition can trigger unexpected limp mode, including at highway speeds. If other PD128 recipients are experiencing the same recall-induced fault and cannot absorb the repair cost, those vehicles may be operating in a compromised condition. We request the federal safety agency investigate whether Recall PD128 is creating safety and repair liability for consumers who complied in good faith.

At about 120,000 miles, my transmission started searching for gears shattering going in limp mode while in drive and then ultimately dying while on the highway. Also, my leaf springs are completely loose. You can just pull them out when you have the truck up on the lift.

Purchased a used 2017 Nissan Titan XD Pro-4X 5.0L diesel on 3/8/25. Left the dealership and only made it ~10 miles down the road before the check engine light came on and there was a loud knocking noise. Immediately turned around and went back to the dealership. After diagnosing it I was told it was a fuel injector and that they were replacing it. Received the truck back ~3/20/25. This truck is not my daily driver but the few times I have attempted to drive it the check engine light keeps coming on and I'm getting a message about the REGEN. On 5/28/25 I had the truck towed to my local Nissan dealership. They diagnosed it and although there is still a code for the same injector coming up they said the issue is the wiring harness and quoted me $7000 to repair and it's not covered under my powertrain warranty. After research it seems like this is a common issue in 2017-2019 Nissan Titan 5.0L diesel trucks which will cause the crankshaft to break if not fixed. I am super frustrated that after less than 3 months of ownership I have an undrivable truck requiring thousands of dollars in repairs.

Received a recall for my vehicle. Recall was pd128. Took vehicle to dealer to have recall serviced on vehicle which was for a pm sensor and reprogram the emissions control module. After recall, DEF system error code and reduce speed to 5mph showed up on truck. Went back to dealer to explain issue after the recall. They ran codes and thought it could be the DPF filter or EGR without thinking the recall could be to blame. Went to another mechanic and did a DEF system check and found no issue with system but a miscommunication with the NOx sensor. Had NOx sensor replaced and a week later had same DEF system error come on but was more intermittent and would clear on its own. Checked codes and found said miscommunication with the same NOx sensor that was replaced. Went back to the original dealer to explain the issue and believe it was due to the recall reprogram. They did a diagnostic and spoke with their own techs and said their campaign recall repair revealed a concern that was present before but did not have detection sensor or the logic to determine the issue and recommends DOC/DOF to to replaced. Contacted Nissan about the issue and if replacement would be covered due to it being tied to the recall and was told no that it is just a coincidence even though their campaign revealed there was an issue with the recall.

The contact owns a 2017 Nissan Titan. The contact stated that the turbo stand, the liftgate latch, and the bolt had failed and were previously repaired. Additionally, the contact stated that while driving at an undisclosed speed, the check engine warning light was illuminated. The vehicle was taken to the dealer, where it was diagnosed that the Diesel Exhaust Fluid (DEF) system and the EGR cooler were leaking. The dealer determined that the DEF tank and the EGR cooler needed to be replaced. The vehicle was not repaired and remained at the dealer for over 6 months. The manufacturer was notified of the failure and offered to partially cover the cost of the repair. The failure mileage was approximately 109,000.

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.
