Owner report 11721157 · 2026-02-28 (February 28, 2026)
Shortly after purchasing the vehicle, I began experiencing serious performance issues. While driving, the vehicle suddenly lost power, would not accelerate properly, and warning lights appeared on the dashboard. The vehicle eventually shut off while in operation. The vehicle was inspected by a dealership, which initially stated there were no issues. However, the problem continued and worsened. The vehicle was then inspected by an authorized Infiniti dealership, where technicians identified a consistent knocking noise coming from the engine. Th…

Owner report 11732566 · 2026-04-20 (April 20, 2026)
While operating the vehicle under normal driving conditions, the engine experienced a significant loss of power and reduced acceleration. The issue is believed to be related to turbocharger failure within the engine system. The loss of power created a safety concern, particularly when attempting to merge into traffic and maintain highway speeds. The vehicle did not respond as expected when acceleration was needed, which could increase the risk of an accident in certain driving situations. The problem has been confirmed by a dealership service…

Owner report 11451597 · 2022-02-11 (February 11, 2022)
I have 3 issues with the car. The braking issue presented itself last in time but is most important relative to safety. Around mid January 2022, my car, while I was driving, and without any notice, began to decelerate/brake for no reason. My car is equipped with front driver assist but there were no cars, hazards, in front of me. It was a clear, dry day and the car was warm. It was momentary and fortunately no one was behind me. The car beeped, but there was no other warning. The second time this same event happened, however, the acceler…

Owner report 11444229 · 2021-12-18 (December 18, 2021)
While vehicle is in “D” drive move the car would jerk likes its trying to shift/switch gears and jerk hard. It sounds like the issue would involve the transmission. Another occasion happened when I came to a complete stop, & then pressed on the gas, and the car jerks again then started to accelerate.
