Having driven 150 miles or so of highway driving using cruise control, stopping two times to rest, driving approx. 65 - 70 mph. I arrived at waltham on rt. 128 where the traffic was bumper to bumper. I had to keep my foot on the brake until I was at exit 38 or 39. We travelled 5 - 15 mph. After I was in the slow traffic for approx. 20 minutes my car started to lurch forward while gassing up and wanting to jump ahead. My foot was on the brake and I needed to brake even harder to hold onto the force that the car was exerting. I was in bumper to bumper traffic and had kept a distance betweeh myself and the car in front so the small jump did not hit that car before I pushed harder on the brake. The same thing happened again within 5 minutes. Once I arrived in danvers I drove to the dealer to report the problem and they gave me an appointment for wednesday8/28/13. This same problem has been hapeening since I purchased the car in 2011. It self accelerated randomly every 3-4 months, it happened when I had my foot on the brake and I was at a traffic light with my mom in the car. I almost went throught the light from a stopped braked position. The other times were after driving with cruise control which I need. It also happened while braking to get into a parking place.
