2018 Nissan Titan Engine Problems

The contact owns a 2018 Nissan Titan. The contact stated that while driving at 40 MPH and accelerating, the vehicle shut off. The contact stated that there was an abnormal pop before the vehicle lost motive power and was pulled over to the shoulder of the roadway. The vehicle was towed to a local dealer, where it was diagnosed with a fractured crankshaft, rod bearings, and engine failure. The vehicle was not repaired. The manufacturer was not notified of the failure. The failure mileage was 127,000.

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).

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. The failure mileage was approximately 62,000.

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.

Engine failure. On rural highway with recreational traffic, engine started rattling, within 5 seconds the engine shut off, luckily I was able to get on the shoulder. My truck is currently at a repair facility 300 miles from my home. Waiting on information from shop and extended warranty company. No warning lights whatsoever.

My 2018 Nissan Titan has suffered two engine failures within two years, with fewer than 37,000 miles on the vehicle. Despite following all scheduled preventive maintenance, the engines failed catastrophically. One of these failures occurred with my family in the vehicle, placing their safety at serious risk. Details: The first engine failure happened at approximately [30,000], and the second at around [37,000], both requiring full engine replacements. These were not minor issues — they were sudden, complete losses of engine power. The second failure was especially dangerous, occurring while driving with my family onboard. Despite clear signs of a major defect or systemic issue, Nissan has refused to take responsibility, treating these catastrophic events as if they are routine, isolated failures. I followed all required maintenance schedules, and the vehicle was well cared for. Nissan’s lack of accountability is unacceptable and deeply disappointing. Based on this experience and their failure to stand behind their product, I will not purchase another Nissan vehicle and cannot recommend the brand to others. I am submitting this report to urge the NHTSA to investigate this issue as a potential safety and manufacturing defect that could affect more owners and put more families at risk.

Vehicle shut down going down the interstate. After investigating, there’s metal in the oil. Possible spin crankshaft bearing or broken crankshaft

Traveling 65mph down the highway, engine started shaking extremely bad and smoke pouring from the exhaust.

Oil doesn’t get to the 7th cylinder causing unrepairable damage. It’s a known issue by Nissan

I was driving down the interstate and my crankshaft broke. It happened suddenly and I lost all power and luckily no one ran into the back of me as I slowed down and made my way to the shoulder. There I sat for 2 hrs waiting for the tow truck. There were no signs or warning lights prior to the engine loosing all power. Nissan inspected and has confirmed it is a broken camshaft and will not warranty it.

Vehicle was well maintained and only drive it around 10,000 miles per year or less. Had no issues or warning signs, my truck just bogged down while going 65mph on the highway. By the time I pulled over and cut it off I checked all fluids and tried to turn it over again, all you hear is a heavy knocking sound like the engine was struggling. Took it to a mechanic shop and found out it had a broken crankshaft, it has under 50,000 miles!

High pressure fuel pump failed (CP4 pump) and put metal through the entire fuel system causes over 10k in repairs and the truck only has 54,000 miles

While traveling at highway speed, engine suddenly started making noise, shaking, and lost power without warning or check engine light. Vehicle was towed to dealer, suspected crankshaft failure, quoted $31,000 by dealer to replace engine.

Earlier this year my 2018 Nissan Titan experienced catastrophic engine failure at only 56,376 miles. I then learned it was due to a manufacturing defect that is very common on 2017-2019 Nissan Titans and other Nissan models with the same engine. This issue is well known to Nissan as evidenced by Nissan Service Bulletin NTB19-057 which was first issued in July 2019. Most failures have occurred when the vehicles are so new that the manufacturer’s warranty provides engine replacement. Mine, unfortunately, occurred three months after the powertrain warranty expired. I filed a complaint with Nissan Consumer Affairs and Nissan took no responsibility and provided no financial assistance. I was forced to pay for engine replacement at a cost of $8,755.03. The website [XXX] has numerous forums relating to this issue with the main thread having 3000+ posts from owners who have experienced catastrophic engine failure. As these vehicles all have expiring powertrain warranties, Nissan is leaving owners like me to pay extremely high repair bills due to this known factory defect. As premature catastrophic engine failure is an obvious safety issue, Nissan should have the responsibility to issue a recall and repair these vehicles. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

Engine started vibrating and shut off on expectantly at highway speeds. Leaving vehicle disabled in traffic. The crank was found to have cracked.

Crankshaft broke on the freeway seizing the motor vehicle 101,000 miles

There is a known issue with the engine where the cylinder 7 is scored. If left untreated it is possible that the engine could misfire or stop working all together due to oil entering the engine. Tried contacting Nissan about it and was told that it is not their problem since it is out of warranty. Currently the engine produces a loud ticking and there is lack of power. A dealership has inspected and confirmed the issue and stated it does need repaired or it is not safe to drive.

I was driving the truck down the interstate with the cruise set at 70-75 mph and without warning, the truck starts shaking violently and making very loud noises from the wngine and then the engine shuts off and power steering is lost while traveling at highway speeds in traffic. The failure was diagnosed as a crankshaft failure which snapped the crankshaft in the engine. The quote from Nissan to replace the engine out of warranty varies between 35k-42k which TOTALS this vehicle for an engine failure that they are at fault for. Nissan knowingly sold vehicles with faulty engines by putting the safety concerns and financial burden for the public to the wayside. This needs to be addressed soon before someone is seriously injured due to Nissan’s negligence and recklessness for customer safety.

While travelling at 80km/h down a slight hill and towing my caravan the vehicle started shuttering vigorously and then the engine just shut down, had to pull up the vehicle using the caravan brakes, Had the vehicle towed back to the Australian Importers as I am located in Australia and they have told me it has a crankshaft failure.

Was driving down the interstate going 70 mph truck started loosing power without any warning or check engine light's. Truck started vibrating violently to the point almost lost control of truck. Dealer says broke crankshaft in motor truck only has 77k miles on it. This should be looked into as it’s happening a lot with models with the Cummings diesel motor. Please look into this before someone is killed. Thank you for keeping us safe.
