Car hesitated when cruising at very low speeds. Lost power when accelerating into traffic or pulling out into traffic. Hesitation upon acceleration. Stalling when stopped, shutter when RPM when below 500 and then car would stall. Cars stalling out at stoplights increased in frequency. Original dealer where car was purchased not interested in helping me with problem. They stated I have to wait till there is a Trottle body recall from Subaru. This car will kill me.
