“I purchased my 2017 Infiniti Q50 as a certified dealer owned vehicle with 4710 miles on it from airport Infiniti on 12/31/2018. Since taking possession of the car, I have had three separate instances where my car lost power during acceleration, in which one of the instances nearly caused me to be hit by a semi-truck when crossing a divided highway. I have provided videos to the manufacture but they have refused to take action because the vehicle does not set any DTC codes. When this condition happens my 3.0t Q50 accelerates extremely slow even with 100% throttle. …”
