While parking my truck, it had an unintended acceleration and my foot was not on the gas peddle. I was going about 1-2mph and the truck picked up speed unexpectedly and collided with my garage wall. I am unsure what component malfunctioned and it has not yet been inspected. Myself and my baby were in the car and luckily I was able to stop by hitting the brakes and putting the car in park. It continued to pull forward even with my foot on the brake. There was no warning or codes prior to or after the incident.
