The contact owns a 2018 Nissan Armada. The contact stated that while shifted in reverse, the vehicle failed to respond; however, the vehicle was able to drive forward. There were no warning lights illuminated. The vehicle was taken to an independent mechanic who diagnosed the vehicle and determined that the transmission needed to be replaced. The vehicle was not repaired. The mechanic, who was a former mechanic with Nissan, informed the contact that it was known failure with the Nissan transmission, and that the shifter was unable to shift into reverse. The dealer was contacted and confirmed that the transmission replacement was not covered under warranty or recall. The manufacturer was not made aware of the failure. The failure mileage was approximately 98,000.

On April 5, 2023, I purchased a used 2021 Nissan Armada SL with 74,429 miles on it. On August 29, 2025, I took the vehicle in for front & rear differential and transmission fluid services. On August 31, 2025, I drove the SUV to Boston MA. The vehicle began a jerking motion and slow acceleration. I assumed it was due to a possible low grade of gas. I filled the vehicle with 93 octane gas. The issue continued. On September 15, 2025, I took the vehicle into Nissan for a further look and was told I needed to replace the entire transmission! After speaking with Nissan's Consumer Affairs, I was told there was nothing that can be done for this issue. The vehicle is less than 5 years old. I have owned the vehicle less than 3 of those years and drove it less than 40,000 miles and now Nissan wants me to pay $11,000 for a new transmission. There has been, no check engine or other warning light indicators alerting this issue or concern. There is no way this can be a normal for a powerhouse company who's reputable as built to last vehicles that their transmission is now only built to last barely past 100,000 miles. This has to be a factory defect in this vehicle. I am presently seeking legal actions concerning this matter. This is a very costly and risky issue that could have left me stranded and possibly caused a serious accident. There needs to be a factory recall for this issue and concern.

Bought vehicle used from dealer so it must have been damaged by previous owner. In less than 1 hour driving in freeway over 60mph in extreme outside heat of 107F, the transmission went out. It was returned to the dealer and dealer is fixing the problems.

At 100,000 miles, my 2021 Nissan Armada experienced a complete transmission failure, requiring a full transmission replacement. The vehicle has been properly maintained. After researching, I’ve found multiple owners reporting similar transmission failures at relatively low mileage. I believe this could be a defect that needs to be investigated and could lead to a potential safety hazard. I am requesting the federal safety agency to investigate this issue for a possible recall.

I was driving on the Mass Pike (Rte 90) when exiting the highway the vehicle lurched and the engine started racing. Then the vehicle had no acceleration and would not go above 20 mph. I towed it to a mechanic who stated the transmission was shot. Six weeks later the vehicle was fixed and the transmission was replaced for a LOT of money!! There was no warning before the transmission broke.

The contact owns a 2019 Nissan Armada. The contact stated while driving 65 MPH, the vehicle failed to properly accelerate. There was no warning light illuminated. The contact pulled over on the side of the road and turned off and restarted the vehicle and the vehicle operated but failed to exceed 20 MPH. The vehicle was taken to the dealer and the transmission was replaced and the engine coolant was flushed and replaced; however, the failure recurred. Additionally, the contact stated that the HVAC system failed to operate as needed. The vehicle was taken back to the dealer and the contact was informed that coolant was leaking into the engine and that the engine needed to be replaced. The vehicle was not repaired.

While driving the vehicle has displayed an intermittent transmission shudder at low speeds when accelerating from a stopped position. This occurs at speeds between 20-40 MPH. The shudder can be felt through the floor into the seat and appears as if the transmission is searching for a proper gear. Under hard acceleration/freeway driving the issue does not present itself. The vehicle has been into both my nissan and infinity dealer. Both technicians who inspected the vehicle confirmed feeling the shudder. Driveline service was performed at nissan and the ECM received the most current update. Nissan technician advised that this is a known problem with the armada and that the shudder is due to the computer trying to find the optimum transmission shift points for the best fuel economy. I brought the vehicle to my infinity dealer after learning that the issue is known to exist in the qx56 & qx80 as well as the armada as the vehicles all share the same components. My service technician drove the vehicle and also confirmed the shudder occurring intermittently under certain driving conditions. I requested that they search for the most current update which would be the "e" update, unfortunately this update only applies to models prior to 2018. Service tech advised me to continue to drive the vehicle normally as this is not a mechanical issue, but a software issue. He also confirmed that nissan / infinity are well aware of the issue and have done little to nothing to provide a tsb, computer update, or permanent solution. He further advised that a transmission replacement, rebuild, or major servicing would not resolve the issue as it is software related. It is deemed very common. This is unacceptable in a $65,000 vehicle. Nissan needs to resolve this issue instead of having dealers advising owners this is normal. My concern is a transmission failure while driving.

On 5 separate occasions 2 on the same trip, whn traveling down interstate vehicle will not pull, like its stuck in a gear and will not shift . Happens around 80 MPH.

Automatic transmission cooling line failure. Our automatic transmission cooling line sprung a leak without warning and no ignition lights turning on. The end result is that the transmission needs to be replaced. After doing some research online, I found out that this is a common problem with nissan armada 2006 transmission cooling lines. The line had a weak spot in it that split open and sprayed all the atf out. This occurred while driving back through our town at about 35 MPH.
