B130D

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. The net result is that when i intend to cross a divided highway, i experience a 1-1.5 second delay from the time i push down the accelerator to when the car begins to move, then the acceleration from 0-15mph can take upwards of 5-6 seconds. The resulting feeling is a car that rolls into a dangerous intersection and exhibits stall like conditions. Only once did the car set dtc codes during this instance. The codes set were B130D, C1A16 and po340. These codes set the first instance, but have not set during the past two occurrences of the same acceleration issue. These instances are completely random which make them extremely dangerous. For instance, the car will be driving completely normal, i will stop and an intersection and then when i go to turn out into the intersection, i go into this stall condition without warning. The dealership has had the car 4 separate times and each time they have refused to fix anything on the car, despite having a video of the occurrence and confirming that the acceleration was entirely abnormal. I have no choice but to drive this car if Infiniti refuses to fix it, but feel it is likely that it will cause injury or death to me and my family if i drive it. I have attached a summary of the daily log i have been keeping since i purchases the car on 12/31/2018.
