The Japanese automaker is at the center of a growing scandal as Nissan and Infiniti owners file lawsuits claiming their vehicles can suddenly lose power or stall while driving.
Nissan has been hit with a lawsuit in the United States after owners of new Nissan and Infiniti models alleged that their vehicles suffer from serious engine defects, putting drivers at risk on the road.
According to the complaint, the problematic VC-Turbo engines have become a major source of frustration for many customers. Instead of delivering the promised performance and efficiency, drivers report excessive vibration, unusual noises, and sudden engine shutdowns.
Lawyers representing the plaintiffs argue that the failures stem from bearing degradation and other critical component damage. They further allege that Nissan was aware of the defects but failed to disclose them to buyers.
Dennis Becker of Florida purchased a new 2023 Nissan Rogue in the spring of 2024. After just 157 miles, a warning light flashed on the dashboard: Engine Malfunction Power Reduced Service Now. Shortly after, the vehicle stalled completely.
Dealers attempted multiple fixes — replacing the battery, updating software, installing new valves — but the issue persisted. Becker says his crossover never became a fully functional vehicle.
According to the lawsuit, Nissan often delayed repairs, leaving many owners to cover costs themselves once warranties expired.
“The defect occurs without warning, leaving drivers in dangerous situations when the engine suddenly loses power or shuts down entirely,” the filing states. Even in non-accident cases, repair bills frequently ran into the thousands of dollars.
The lawsuit highlights several models allegedly affected by the defect, including the Nissan Rogue (2021–2023), Altima (2019–2023), and Infiniti QX50 (2019–2023). Many owners have expressed skepticism about Nissan’s service responses, claiming that dealerships often resorted to simple oil changes that failed to resolve the problem.
The U.S. National Highway Traffic Safety Administration (NHTSA) has also shown interest in the issue. In 2023, the agency recorded numerous complaints ranging from knocking noises to metallic debris found in oil pans.
Two engine types are under particular scrutiny:
At the time, nearly half a million vehicles equipped with these engines were on U.S. roads.
Nissan has declined to replace engines wholesale. Instead, affected vehicles are sent to service centers, where technicians inspect the oil pan. If metal shavings are found, the engine is replaced; if not, fresh oil is added and the vehicle is returned to the owner.
For 1.5-liter engines, additional measures include updating ECU software and replacing a gasket, while the 2.0-liter engines generally receive only an oil change.
Earlier this summer, Nissan narrowly avoided a massive recall of 2 million vehicles in connection with suspension concerns in Altima and Maxima models. Despite reports of cracks and corrosion, regulators deemed the risk “manageable” and limited their response to issuing safety recommendations.
