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.

My crankshaft broke on the highway. I was travelling at around 70mph. No warnings were given. I lost all power and had to limp it off to the side of the road. The engine was replaced under warranty. This is an ongoing issue for 2016-2019 Nissan Titans. Folks are left with worthless vehicles because they are outside of their warranty period when it happens.

I had a check engine light for catalytic converter bank 1. Added a cleaner to see if that would help - instructions mention run 1 - 2 tanks of gas after adding, so I did that, it took a while since I dont use the truck as often. The light did not clear so I was planning on bringing it in. I was on the highway and the check engine light starting flashing and power loss occurred. I limped off the highway and got it towed. It had 3 codes on check engine light. Other than the check engine light, no warnings, messages, nor symptoms appeared or occurred prior to the flashing check engine light. Got to Mastria Nissan, they looked at it for not long (morning) and said the engine and other components were junk. Presented a $27,000 bill. They did not tear it down nor illustrate what went wrong. Police nor insurance inspected the truck. Safety was compromised as it died on the highway where everyone was doing 70 plus. Had to limp off the highway as the pull off area was very busy and not spacious whatsoever. Truck has 28,000 miles on it and was planning on the 6th oil change. The first 2 were done at Nissan and I changed the oil myself other times. Drained oil had an appropriate volume. No oil has ever leaked. I have order history on oil and have the last oil change oil in my garage still. I filed a claim with Nissan corporate, I have emails with them, but i got a denial over phone on January 5th. They claimed they dont have enough service history and im 6 months out of warranty. Also, on the call, they refused to send the denial by email or regular mail.

Imminent catastrophic engine failure on 2018 Nissan Titan. The engine has developed severe cylinder wall scuffing and loss of compression (150psi vs 264psi spec) on multiple cylinders. This defect can cause loss of power and potential stalling at highway speeds, presenting a safety risk. The failure matches Nissan TSB NTB19-057 (knock/scuffing). Despite a perfect maintenance history, Nissan is denying warranty coverage by claiming there was no oil change service record because the maintenance was not done at a Nissan dealership. The local Nissan dealership confirmed the issue matches the TSB and an independent inspection confirmed the defect is mechanical (piston/cylinder clearance).

My vehicle lost power driving down the road while pulling my horse trailer. The engine began to vibrate and knock then shut down completely. I did not make it off the road entirely so the police had to assist with lights to ensure other motorists would avoid collision with me. The engine will not turn over, it makes a single click and is locked up completely.

1. Turbo Actuator / Dealer is currently replacing the defective part. 2. When this part fails, you lose throttle control and acceleration capabilities. This part failed on me at highway speeds, and I had to drift over several lanes of high-speed traffic. I was unable to control the speed of my vehicle, with no ability to accelerate. 3. Not sure if they duplicated or are replacing the part solely by the check engine code of P00AH DTC (Check engine code). 4. It is a known issue with Nissan, and they have extended warranty coverage for 2016 and 2017 model year Titans with the diesel motor, but have refused to address it with the 2018 model, even with the same symptoms and DTC. 5.No, when the failure occurred, the check engine light came on, and the truck lost power. Occurred around September 25, 2025, mileage is 61,489. A claim was filed with Nissan North America under case # 55882533, and they have denied to cover the repair.

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)

Check engine light went on and the Truck went into low power mode. Took it to an independent service center and it was no longer throwing the code. It happened a couple more times, took it to the dealership and the diagnostic was: Setting in ECM., Actuator is Binding causing DTC and vehicle to go into Reduced Power Mode. This seams to be a very common issue in Nissan Titan XD's. Maybe should be a recall? A very pricy repair for a vehicle that only has 45000 miles on it.
