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.
NHTSA complaint #11753451 — an unverified report by a vehicle owner.
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)
NHTSA complaint #11748360 — an unverified report by a vehicle owner.
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.
NHTSA complaint #11748060 — an unverified report by a vehicle owner.
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 NHTSA investigate whether Recall PD128 is creating safety and repair liability for consumers who complied in good faith.

NHTSA complaint #11734670 — an unverified report by a vehicle owner.
The contact owns a 2018 Nissan Titan. The contact stated that while refueling, there was an engine run-on after the vehicle was turned off. The contact determined there was a vapor lock issue and that air was entering the fuel system. The vehicle was difficult to start. There was an abnormal clicking sound coming from the vehicle. There were no warning lights illuminated. Upon research, the contact determined that the failure was like TSB: NTB19-049. The contact used a scanner and determined the failure was related to the fuel pump module. The local dealer was contacted and confirmed that parts were on back order. The contact called another local dealer, Victory Nissan Parts Center (307 Thompson Ln, Nashville, TN 37211); who confirmed that parts were backordered for approximately 6 to 8 months. The failure mileage was approximately 62,000.

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.

I tow full-time as a working nomad. My truck has gone into limp-mode (low-power mode) onto a complete loss of power. I have been stranded on 3 difference occasions. The issue first began at 75,000 miles which I have records of. After this most recent incident, I realized there was a pattern emerging. After further research, I have discovered that there is a lawsuit out for these CP4 fuel systems. I called Nissan and opened a case number. They processed and then stated that they will not assist me since I am not over 100k miles. My odometer is currently at 105K miles. I am not sure if it is safe to drive my truck and I need to relocate soon. What options do I have? Can anything be done about this? From what I am reading online, this is a $10,000 - $15,000 to fix, let alone the thousands of dollars I have already spent on varying part replacements. Nissan/Cummins designed this truck to work with the fuel being sold in Europe. The fuel in the US does not offer the lubrication required to function properly and it’s causing friction on metal which is sending metal shavings in through the fuel system. The fuel filters cannot handle the debris. The only warning signs I received from the vehicle was a dash warning stating low power / no power mode had been engaged as I lost power and had to roll to a stop on the side of the road. Thankfully I was able to get over to safety each time. Then, I stayed stranded on the side of the road (single female traveling alone with dogs) until I was able to figure things out. Nissan refused to tow or offer any support. Existing Lawsuit: [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)
NHTSA complaint #11691057 — an unverified report by a vehicle owner.
I am experiencing engine stalling. I have also experienced dome light flickers or not turning on on occasion along with radio and phone charge connection not always working, like a short of some sort. Also the mirror button allowing the driver and passenger side mirrors to open close sometimes fails as if wiring is OK sometimes and other times not There is not an exact date for the issues as they have occurred on and off since 2019 I did take the truck into Nissan 11/2023 as the radio blacked out and would not turn on. I was told the Main Harness had a shorted out wire and a jumper wire should be installed. Nissan installed a jumper wire for the radio. Occasional flickering lights, charging connections, mirror operations, and engine stalling still remained.

NHTSA complaint #11677394 — an unverified report by a vehicle owner.
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.
NHTSA complaint #11665318 — an unverified report by a vehicle owner.
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.

While driving my car would almost stall on the highway, if I gave it gas while merging onto the highway it doesn't respond and then almost stall, but then respond after 2 seconds when it was not as clear to merge on the highway. I have had to replace the battery twice and been stranded in the last 3 years, the engine would pretend to start but not kick over. I have seen that this is a common problem when looking into Nissan TItan Forums

The vehicle was taken to a dealer and the contact was informed that the fuel system error in the fuel pump system needed to be replaced. The vehicle was not repaired. The manufacturer was notified of the failure. The failure mileage was 61,888.
NHTSA complaint #11641179 — an unverified report by a vehicle owner.
Gas spilling out when refilling. Fuel tank had been whistling from beginning ownership in 2020 but no problem refilling. Most recently however gas will quickly overflow when attempting to fill. This has occurred several times recently, but it was never an issue before. Spillage is not dependent on tank volume. Spillage occurs when low and/ or mostly filled. I have to trickle gas from pump in order to fill, but this takes quite a while to put in several gallons. If I attempt to fill normally gas will come gushing out after a few seconds.
NHTSA complaint #11626128 — an unverified report by a vehicle owner.
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.
NHTSA complaint #11616930 — an unverified report by a vehicle owner.
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.

The vehicle has loss of power and goes into limp mode unexpectedly. It has done this numerous times on the interstate and regular roads. It is a safety hazard. This has occurred on several dates and we were lucky to be able to pull over safely. We we traveling in Georgia last month and Nissan didn't even have a qualified diesel tech with 3 hours of where we were. We have had ten of thousands of dollars of work to the truck and it still is not fixed. They replaced the computer screen, wiring harness, and I believe parts of the exhaust system. They had the truck for months.
