What 90 owners told NHTSA about the 2018 Nissan Titan

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)

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.

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)

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.

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

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.

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.

While Driving in normal Driving conditions, The Auto at 30 mph will Rev the RPMS up to as much as 5000 rpm before the Transmission will catch and accelerate loosing the ability to accelerate on demand when needed such as merging on to a Highway of speeds of 55 mph or higher. This behavior happens almost every single time acceleration is demanded and is not due to a lack of ATF fluid in the transmission. As the vehcile has done this after The local Service center of nissan in my area had just done the 20k mile check up. This has been on going and constant behavior since I purchased This nissan Titan in 2021. Truck currently has 35k, and has had all service suggestions done. This is a danger to my family and myself as lack of power can cause extreme danagers when you are trying to gain speed to merge onto a busy highway and you are running out of roadway to gain speed and you have to use the emergency lane to have access to safe area to gain enough speed to safely merge. This is a well known issue with this model, as I have been seeing other owners complain for sometime online in forums, when I researched if anyone else had this issue.

1. THE VEHICLE HAD TO BE BRAKED HARD ON THE HIGHWAY TO AVOID A CAR THAT FAILED TO YIELD WHILE MERGING. THE OTHER VEHICLE THEN BRAKED HARD AND I ATTEMPTED TO ACCELERATE TO GET IN FRONT BUT THE VEHICLE WOULD NOT RESPOND TO THE GAS PEDAL. THE ENGINE DID NOT SHUT OFF, BUT THE TRUCK WOULD NOT REV THE RPM'S OR HAVE ANY RESPONSE TO THE GAS PEDAL FOR ABOUT 3 SECONDS. LUCKILY A COLLISION DID NOT OCCUR. 2. WHILE TAKING A RIGHT HAND TURN ONTO A STEEP INCLINE DRIVE FROM A HIGHWAY THE TRUCK ONCE AGAIN WOULD NOT RESPOND TO THE GAS PEDAL. THE TRUCK WAS JUST SITTING ON THE INCLINE FOR ABOUT THREE SECONDS BEFORE IT RESPONDED TO THE GAS PEDAL AND CLIMBED THE HILL. THERE WAS A VEHICLE FOLLOWING BEHIND INTO THE DRIVE AND HAD TO STOP TO AVOID COLLIDING INTO MY REAR END AS THE TRUCK WOULD NOT GO FOR A FEW SECONDS. I AM NOT EXACTLY SURE HOW TO DESCRIBE THESE TWO INCIDENTS OTHER THAN IT IS A "DEAD PEDAL" FOR SEVERAL SECONDS WHEN PROPULSION IS TRULY NEEDED
