NHTSA Complaint #11679819 — 2024 VOLVO XC40

I pulled over right side of street to park behind a parked vehicle to a visit house across the street. Was too far out from curb so I backed up about 12-15 feet or so. Put car in drive and slowly started to drive toward curb when car suddenly accelerated very hard. I turned steering to left to avoid hitting the car in front, straightened car out but could not stop it until it stopped about 20-30 feet down the road. Brake was not stopping my car. The acceleration was something like being on a ramp to get on highway and pressing pedal down to get to highway speed. It was a very hard acceleration. Very frightening. I got an appointment tomorrow for volvo service to look at this. Drove the car after this happened and today without any incident. I bought the car new in Mar 2024 and have NEVER experience this.
