Mileage when the problem started
Owner reports
Selected complaints filed with NHTSA by 2017 Nissan Titan owners, lightly cleaned up (personal details are redacted by NHTSA).
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.
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. …
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 [redacted] 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 #[redacted] 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. …
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. …
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 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.
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.
Unknown - while driving my vehicle several warning lights started popping up all at onces the lights on the dash where glitching. Then all the power to my dash an possibly other parts of vehicle lost connection. Vehicle wouldn't even show speed or what gear I was in. While I was driving with 2 small children in the truck. I immediately pulled over. I have since taken my vehicle to a dealership where it's been for a couple weeks. They where unable to give me an exact diagnosis so my warranty won't cover repairs yet. I now have to tow my vehicle 96 miles to a different dealership in hopes of getting it fixed. My 2017 truck will not even start now!!
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.
Lift pump failure. Part # 16400-EZ40B. This part has been replaced by dealer three times in the past year. Seems to last for about 8K-10K miles or so. Vehicle won't start when lift pump goes out just a warning of "low fuel pressure". Then has to be towed to dealer.
