NHTSA Complaint #11458867 — 2015 INFINITI QX60

The vehicle on at least 4 occasions has stopped accelerating when driving the vehicle (first time I believe was fall 2021, this last time was Spring 2022). Most of the times that the issue was noticed, the car was was moving at slower speeds (35 or less). The engine remained running but pressing on the gas pedal didn't make the vehicle increase it's speed. The first time it did this we took it to the dealership to inspect. They could not replicate the issue and they said that no error codes showed up. We left with no repairs or answers. It happened 2 more times after that. Each of those times we were able to stop the vehicle and get it to go again or it would start to respond to pushing on the gas pedal and would accelerate. The 4th time this happened I was in the middle of an intersection turning and it wouldn't accelerate. I was able to slowly roll into a gas station. I tried stopping and turning the vehicle off and on again to see if the problem would go away, however each time the car only slowly inched forward. I parked and then the vehicle started acting weird. The AC shut off and the steering wheel locked. There were three error lights that came on. The first said "FCW Malfunction See Owner's Manual" and second was "IBA OFF" and then the "! inside a triangle" appeared. These appeared only after stopping the vehicle for the last time right before it wouldn't start again. The vehicle was towed to the dealership. The error reading they got was c1601 and they believe the alternator needs to be replaced. This doesn't seem to line up with the issues we have been having nor the error warning lights that appeared. The last time this happened my child was in the car with me. Had we pulled out to turn and the car wouldn't go we could have very easily been hit by oncoming traffic. It is very troubling that the dealership doesn't seem to really know what is wrong with the car.
