Electrical system
Vehicle was purchased December 2021 upon purchasing the vehicle I noticed the horn was not functioning, vehicle was taken back to dealership, they corrected the issue, then months later horn isn't functioning at all. Nor is Lane Departure Warning, Lane Keeping Assistance, Parking Collision Warning, Rear Cross Traffic Warning functioning on car. The automatic rain sensor isn't working at all.
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 accelerator pushed back against my foot. Again, no one was in front of me and it was a clear, dry day. The third time this happened, the car beeped and what I know now is the cruise control indicator, appeared on the display. I did not touch the cruise control to activate. …
Transmission & drivetrain
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. The dealership indicated that the noise is consistent with internal engine damage and recommended further inspection and likely engine replacement. The issue developed very shortly after purchase, and there were no prior indications that the vehicle had been damaged or misused. …
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 department, and the vehicle is currently available for inspection. The diagnosis indicates that the turbochargers require replacement. Prior to the failure, there were limited warning signs. Any warning indicators were either minimal or appeared shortly before the issue became noticeable. The failure occurred at approximately 107,000 miles. …
