2021 Nissan Armada Powertrain & Transmission Problems

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.

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 NHTSA to investigate this issue for a possible recall.
