general problems of the 2010 Dodge Dakota

The roads were slick and I was traveling slow came over the crest of a small hill over bypass and headed down hill braking slowly I could tell it felt like I wasn't slowing down like I expected as I approached a vehicle ahead of me stopped at the traffic light,so I pumped the brakes twice and the engine roared and my truck raced forward and crashed into the vehicle ahead of me. The other driver was very angry and wouldn't believe me when I tried to explain what happened. He would not exchange information with me. My foot did not slip. I can't even get my truck to surge forward like that if I hit the gas hard.
