NHTSA Complaint #11618357 — 2018 VOLVO XC60

When I had to slow down or suddenly stop because there were other cars in front of me, I. stepped on the break, but it did not stop; maybe it slowed down a little, but the acceleration seemed to accelerate faster. I could hear the acceleration sound. I had to push the gear to stop. The car finally stopped. But I almost hit the front car. Similar occurrences happened when I came to a stop signal, which could have involved me in a serious accident, even fatal. I still drive the car because I have only one car. Most of the time, it works normally, but the problem occurs occasionally. I am scared, thinking it will happen again.
