the brake pedal rises to the top, so you have no give to the pedal at all. I begin running through all the electrical gadgets, like opening and closing the tailgate, locking, unlocking the car, radio on and off, etc. hit everything on the fob several times. the radio, nav, system will work. was suggested by dealer to make sure you don't pump brake before trying to start. have tried it both ways and cannot replicate. have had it to the dealer twice. they say no computer mods were tripped. they don.t have a clue, and neither do I. about 5 minutes after it happens suddenly the car will start as if nothing was wrong. each time it has happened, the car has been driven, sometimes short mileage, sometimes longer mileage. so far, just annoying. everything else is fine. really like the car.
