The engine is failing on many Nissan vehicles with the Nissan VK56VD (gasoline V8) engine. Cylinder 7 on the engine has significant scouring, and there is a Nissan Technical Service Bulletin (NTB19-057a) indicating this problem is widespread among 2017-2019 Nissan Armada, NV, Titan, and Titan XD models. This is a major safety concern. When there is a problem with the engine, the vehicle may stall, lose power, or even catch fire. If a driver loses the power from the engine while driving, or is unable to accelerate as expected, the vehicle could be at risk of getting hit, seriously injuring the occupants of all vehicles involved. The problem has been diagnosed, reproduced, and confirmed by Kline Nissan in Maplewood, MN. The vehicle was inspected by Kline Nissan. Diagnosis details attached, along with borescope photo showing significant scouring in Cylinder 7. Repair action is a new engine short block. My vehicle was outside the 60000 mile powertrain warranty window at the time of inspection. My service advisor at Kline Nissan contacted Nissan Consumer Affairs to submit a Factory Goodwill case, but was informed by Nissan Consumer Affairs that they would not be assisting in the replacement of their defective engine. The concern I share with NHTSA is the cost I was quoted to repair this problem is $9203.70. This problem is so widespread, among 3 years of Nissan's vehicles, I expect very few vehicle owners outside of the warranty window will be investing this level of repair in their vehicle. As a result, many of these engines to fail on the road, putting the public highways and roads at major safety risk. There are no warning lamps or messages for this problem, simply a tick noise that gets louder over time as the cylinder continues to get scoured, worn and damaged. This will eventually lead to damage significant enough to unpredictably blow the engine while driving which would be a major safety concern putting the vehicle occupants and others on the road at risk.

The transmission is shifting incorrectly at low rpms. I can clearly see the RPM fluctuating especially going uphill. This happens 30-50 mph.lack of power/acceleration. Feels like transmission is shifting in lower gears too sooner and and won't accelerate until driver pushes significantly. This is very dangerous especially making turns at stop lights.

Went to start my vehicle and everything but the engine would start. Tried for several minutes, locked, unlocked car then left it alone for 5 minutes and it finally started. Then, less than a week later, while I was driving, the bci malfunction warning and a bunch of other lights came on and car slowed down significantly. Had to pull over, look up this warning and follow directions others who had this same issue did. I turned vehicle off, waited a minut and turned it back on. Warning cleares. The next morning my car wouldn't start. Had to swap cars with husband so I could get to work. This morning I tried to start it again and it wouldn't start. I've now been waiting 3 hrs for a tow truck to get vehicle. Vehicle has less than 40K miles and is a 2017 model.

Vehicle intermittently displays a bli malfunction and decelerates the vehicle while driving highway speeds. It occasionally does it while idling and will not allow the car to be put in gear. When it happens at start up, it will not allow the vehicle to start and only activates the accessories. The incidents began happening at around 55,000 miles and has been continuous and increasing in frequency since 6/20/20

Car gave a bci malfunction warning on dash. When I turned the car off and went to restart it would not restart. This used to happen once every couple of weeks. It is now happened more than 10 times in the last two days.sometimes the car will start other times I have to try 15 times or more before it starts.

From slow starts, the tachometer will flutter and that hesitation is transmitted through the drivetrain to the wheels.

The contact owns a 2017 Nissan Armada. While driving 5 mph, a rambling noise was present at the rear of the vehicle. Also, all the warning indicators illuminated before the vehicle decelerated. The vehicle was taken to the local dealer (jp motors, Inc., 3675 frontage rd, peru, il) where it was diagnosed that the throttle was faulty. The throttle was repaired, but the vehicle continued to experience the failure. The vehicle was towed back to the dealer where it was diagnosed that the air suspension was faulty. The vehicle was repaired, but the failure later recurred. The vehicle was taken back to the dealer, but the cause of the failures could not be determined.
