The engine just quit while i was driving on the freeway during morning rush-hour. there was suddenly no response when accelerator was depressed. i managed to glide across 2 freeway lanes to exit freeway while car decelerated. this occurred on oct 7, 2008. i don't recall if at the off ramp red light, the car completely stopped and i restarted it or was barely idling. i do recall the car barely driving (it was trembling/rough idling) the few feet from the red light to the first gas station. i parked it and it would not start up. hyundai towed it to their dealership. mechanic diagnosed the problem was: "the throttle body has failed and needs to be replaced." i haven't experienced this again--and had not experienced it before this incident. while i managed to avoid crashing into other vehicles going 50-70 mph when i glided across the lanes, this was a terrifying experience. (i am submitting this complaint 1-1/2 years after the mechanical failure only because of the serious problems toyota customers have experienced w/sudden acceleration, etc. i just want to ensure that nhtsa was informed by hyundai back in 2008 of my potentially deadly engine failure on a freeway during rush-hour traffic. i think they should have had a duty to report this serious failure to you, and if they did, great. in case they didn't, now you know.) *tr
