Mercedes C300 4Matic 2019 model, active brake assist malfunction (not working )

- Fremont, CA, USA

On September 5th around 4:30 pm, I made a complete stop at a red light, on the intersection of sykes creek pkwy and sr 520 in merritt island, Florida. Weather was perfect no rain or wind. I applied the brake hold feature and lifted my foot off the brake pad. About 3 minutes passed and suddenly the engine turned on and the car moved and collided with the car in front of me and she hit the car in front of her. It was not hard hit as evidenced by the minor scratch on my front bumper (car #3) and another minor scratch on the car in front of me (car #2), and no sctraches at all on the car in front of her( car #1)
