I've had my 2019 I-Pace HSE for about 18 months now (5,600 miles due to not driving too much during Covid), and while driving home today on a side street going about 20 MPH, the car suddenly slowed to almost a halt even though the accelerator was depressed. I then pressed down on the accelerator harder and the car would only go about 2-3 MPH in speed. I was able to pull over to the side, place the car in park, turn off the car completely, and restarted the car. Once restarted, I was able to put it back in "D" and everything was back to normal. I then drove it around a bit to see if the problem came back, but I could not reproduce the error. There were no warning lights, turtle sign, or error messages during the entire ordeal. I'm due for a 6-month service now, so I'm going to bring this up to the dealer and see if they can check everything out. I'm just glad that this happened while I was in my neighborhood moving at a slow speed rather than on the highway or trying to turn onto traffic. I'll update if the service department finds any issues related to this.
