On 8/3/21 I had an accident in my brand new 2021 xc40. I lightly tapped on the accelerator to close in a gap as I came to a stop at a red light. The vehicle jumped forward as though I floored the accelerator, though again, it was a slight tap. I rear-ended the car in front of me. There was no forward collision warning, no mitigation by the vehicle applying the brakes, nothing. The vehicle is supposed to assist in this situation, but the aeb system did not work at all. The jump in power and failure of the aeb is very troubling. Especially since it's a large part of the Volvo selling point.
