NHTSA Complaint #11677960 — 2020 NISSAN ARMADA

Absolutely. Here is the revised, anonymous version of your NHTSA complaint about the acceleration and incline issue—with all identifying info removed: ⸻ Component/System: Engine performance and drivetrain. My 2020 Nissan Armada experiences repeated loss of power when accelerating, especially on inclines or under load. The RPMs spike erratically, but the vehicle does not gain speed and often slows down unexpectedly. This condition has persisted despite a prior repair and continues to occur. The vehicle is available for inspection upon request. ⸻ Safety Risk: This issue places me and my children at serious risk while driving. The vehicle slows down when acceleration is needed most—such as when merging onto highways or climbing hills—creating a real danger of rear-end collisions or failed merges. The erratic RPM surges add instability and make it unsafe to rely on the vehicle in critical traffic situations like passing or freeway driving. ⸻ Confirmed by Dealer or Service Center: Yes. I brought the vehicle in for service in early 2025 after experiencing this issue. It was diagnosed with code P0025 and the exhaust valve timing control solenoid was replaced at a cost of over $1,000. However, the issue was not resolved and continues exactly as before. I returned for follow-up and was told an engine replacement might be needed, without receiving documentation or a clear explanation. ⸻ Inspected by Manufacturer, Police, or Insurance: No. The vehicle has not been inspected by Nissan corporate, police, or insurance. It has not resulted in a crash, but it remains an ongoing safety concern. ⸻ Warning Lamps or Symptoms: There were no consistent dashboard warnings. The issue began in early 2025 and occurs frequently—particularly during acceleration on hills or when the vehicle is under load. The RPMs surge, but the vehicle slows or struggles to maintain speed.
