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)

Worst dealership my husband and I ever dealt with. We purchased a 2019 Nissan XD Titan Diesel with warranty. Two days after purchase, the check engine light came on. I called Spencer from the service department to let them know. They took the truck the very next day; it was some issue with the gas tank, so the part was back-ordered. After getting that fixed, the check engine light still never went off. I questioned the dealership; all they could say was it was probably a dirty sensor. Then, not even two weeks later, I was leaving a doctor's appointment on the interstate when it threw up a code for low coolant, saying it was about to go into limp mode. So, I made it to the dealership's service station. They said it was okay and couldn't find anything wrong with it, then told me to just keep driving it until it broke down or delete it if it was them. They said, 'You know, we don't deal with a lot of diesel, so it may need to go to another dealership.' Then, two months went by, and we had more issues. We ended up back at the dealership to find out that it now had an oil leak that was quoted to us as a $14,000 job for parts and labor. We also had extended warranty and powertrain, but Spencer failed to file the warranty claim correctly the first time and filed under the wrong warranty, so they denied it. We had to call management to get them to check why, and the problem was that the service department didn't know how to file the correct warranty claim. After that was submitted, my husband asked Spencer directly and the service department if they did rentals through our warranty. They said they don't give rentals at that dealership. Note that we found out later through our warranty that they did pay, but we weren't given that chance. After picking up the vehicle, the check engine light was still on !!! there’s so much more details to the story!!!!!

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.

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.

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.

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.
