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).

While driving on Interstate 20 at a 75 mph speed in traffic, the truck began a loud knocking noise and the engine shut down. After fighting the dead truck off the roadway from the highway speeds and avoiding traffic, I was able to get the truck safely stopped. Upon attempting to restart the engine, the starter caught on fire. I was able to get the fire extinguished with minimal damage. The truck was towed by a wrecker to my home. I replaced the starter and inspected the wiring harness for fire damages. The truck did restart after sitting for several days, and the knock which was heard on the roadway the day of the failure was excessive. After other checks and inspections, the crankshaft was found to be broken in half causing loud knocking. This is a catastrophic failure with a monetary replacement of approximately $20,000-$30,000.

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!

In November of 2022 we heard a knocking noise from the engine and then the low oil warning came on. Vehicle would then not start. When we towed it to the dealership they found noise from the bottom end and low oil pressure code P0524 and verified engine will not start and does make a bad knocking noise during short crank period. Determined the engine came apart internally and had large rod and main bearing material in oil pan loose metal ran through engine and engine will need to be replaced. We had all necessary warranty work done at the certified dealership and all oil changes were done as recommended, all documentation sent to dealership. Nissan would not cover the damage, we were 12,370 miles over warranty and still owed $24,000 on the vehicle. On April 4/17/2023 we paid $17,977 for a new engine on the truck. Upon our research this is a "known" issue with this engine and the crank shaft failing.

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 purchased the vehicle new in july 2018. When the engine started making a knocking sound I took it to a nissan dealer ship to be diagnosed. I was told "they were aware of issues with some of these engines and 2 other vechicles have already required the motors be replaced by their service department. I decided to get a second opinion so I went to another nissan dealer. This dealership confirmed that they have a factory notice stating there are issues with this motor. The dealership is tellling me they can not perform the factory required test for three weeks and if it is determined it is a defective engine it will be another 3 to 4 weeks until the engine can be replaced. In the mean time I am still driving the vehicle. In the event that this engine fails at a high rate of speed there is a potential for loss of steering and loss of brakes. Currently there have not been any recalls or notices sent out to the consumer and from what I am told it is unknown how many of these vehicles are defective and currently on the road.
