My wife and i had just left a local business mid-day on a warm dry summer day. was less than a block away and traveling slowly at approx 20 mph. applied brake as we rolled up to a stop sign. engine started to increase rpm on its own requiring evermore increasing brake pedal pressure in an attempt to come to a stop. standing on the brake pedal engine rpm reached 2500. i put the gear select into neutral. the brakes grabbed, the engine rpm shot up and returned to standard idle. i put the car in drive and car behaved normal after that. this has occurred approx 6 times over past year. took it to dealer twice with no resolution. floor mats secure and locked down. i drive right foot only and brake cleanly and square on the brake pedal. this only occurs at low speed, when engine is warm, and even squealed the tires ( burned rubber ) once. must slam into neutral to get it to stop. *tr
