2021 Infiniti QX50: check engine light

Filed Dec 13, 2025 · Electrical, Engine · GA

Around 530pm At the corner of Briarcliff Rd NE Atlanta Ga and N Druid Hills Rd NE Atlanta GA As I was about to accelerate after the Red Light turned green, my car experienced a significant loss of power. Several warning lights came on, the engine light came on and a warning that said System Default came on. I was almost rear ended but was able to put on my hazards and coast to the side of the road, where I turned the car off and back on. It continued to display the warning and system default message as well as loss of power. I was able to coast into the parking garage at work and park. I am a healthcare worker and my shift ends at midnight. I have a 30 minute drive home and I’m afraid my car may do the same thing-lose power- and that can be catastrophic on the interstate. This is not the first time this has happened. I took my car to Infiniti and they said the recall was cancelled for now. I have two small children that I have to transport in my car and it is unsafe. We need a solution asap!

Vehicle Issue Summary – 2021 INFINITI QX50 I purchased a 2021 INFINITI QX50 in March 2024. Recently, I received notice of an active safety recall (the federal safety agency 25V437) related to the VC-Turbo engine bearings. In addition to the recall alert, I’ve also experienced several concerning symptoms: 1) A knocking noise when reversing. 2) The malfunction indicator light turning on and off intermittently. 3) Other irregular behaviors that raise concerns about engine performance and overall safety. Given the recall and these symptoms, I’d like to schedule an immediate inspection and any necessary repairs. My job requires me to drive multiple children on a daily basis and is a safety concern for the family I work for. This effects my work situation tremendously and my ability to perform my job responsibilities.
