2017 Nissan Titan: fuel pump failure

Filed Jul 29, 2026 · Fuel system · GA

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 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.

Vehicle began shutting down on the freeway. I hooked up an OBDII sensor and it detected a turbo code. Took my vehicle for warranty work on 12/23/23. Dealer Refuses to fix warranty issues. Trying to add on additional repairs that aren't needed. I have pictures of my own OBD2 sensor showing DTC P00AF, indicating turbo actuator or high pressure turbo charger that is specifically detailed in Quality action campaign bulletins issued [XXX]. Reference: PC919, PC920. [XXX] claims no such codes detected. But he wants me to replace fuel pump and fuel sending unit. This guy also wants me to pay $250 for a full diagnostics and add other issues that are not covered by warranty. Per Nissan warranty process, "Warranty repairs will be made at no charge for parts and/or labor, INCLUDING DIAGNOSIS AND TAX." Now they say the catalytic converter is damaged and needs to be replaced with costs in excess of $15,000. However, the vehicle was passed smog check in september. In addition they are saying to begin work, I need to pay 70% of the cost by wednesday or they begin charging storage fee of $50 a day. And still have not addressed warranty issues.

On Friday, Oct. 6, 2023 I was driving my 2017 Nissan Titan Turbo XD that I just purchased in December 2022, it just lost power and stopped on the highway in the dark. I was able to get it to the shoulder and waited 3 hours for a tow truck. This happened on a deserted road in Washington state. I was able to get a rental car for the weekend, but the only technician qualified to look at my truck couldn't do so until Wednesday the 11th. The diagnosis was metal shavings in my engine oil, meaning I needed a complete new engine. The cost is $31,400 - and the truck cost me $37,000. Upon doing some research, I have found that the diesel fuel pump, the cp4, that comes in the Cummins diesel engine that was put into the Nissan Titans from 2016-2019 was not mean to have US diesel run through it. Only European diesel, which is more lubricated than diesel in the US. This cp4 need for lubrication makes it break apart and seize your engine up when used with US diesel. This is a known issue with the Nissan titan XD Turbo, and Nissan stopped making the truck in 2019 partly because of this issue. There has been no recall on the engine or the truck, and I could have easily been killed or seriously injured when my truck just stopped in the middle of the dark with no warning. No lights came on, nothing. I take meticulous care of my vehicles and as an Army Captain stationed at Fort Lewis, am well aware that routine maintenance is imperative. There was nothing that alerted my previous service technicians nor myself as to the danger that this truck contains. It's a ticking time bomb and needs to be taken out of use by Nissan, and their consumers compensated. How long until someone is killed due to the defect?

The contact restarted the vehicle and drove to tony nissan (04-1299 ka uka blvd, waipahu, hi 96797). The dealer stated that due to the location of the fuel pump sensor, if there was less than a quarter of a tank of diesel fuel, the vehicle would stall. The vehicle was repaired. The manufacturer was notified of the failure. The approximate failure mileage was 55,000. *ln

To whom it may concern I was driving with slightly less than 1/4 tank of gas and stopped to park on a hill with vehicle on idle. While in idle on the hill the vehicle stalled out. I tried to restart but the engine just cranked with no start and a low pressure fuel system service light came on. I tried to push it down the hill on flat ground and tried to start again with just cranking no start. I then had to push the vehicle with the help of my neighbors into a guest stall and call for a tow. The vehicle was towed to tony nissan to be looked at where the mechanic said that there were no issues and he reviewed all the fuel system and no issues were found. He informed me he let the vehicle crank over until the pump was able to pick up fuel and purge the line of air and the car started. The service advisor informed me of the fuel tank being longitudinally placed in the truck with fuel pump in the center which stopped to idle on a hill may have caused the pump to go dry and pump air. I informed him that this could be an issue if I was driving up or down a hill with my family and then stop and idle whereby the truck stalls out on a hill of such magnitude like in san francisco or wilhemina rise in honolulu, hi. Hopefully this is reviewed by the engineers at nissan motor which this email is also being forwarded to the federal safety agency. Invoice number, I believe, from tony nissan is 653922.
