Car has stalled while driving. sometimes it will not go into gear. other times it only goes into first gear. had to move it to neutral then back to drive to get it to work. other times, had to turn it off completely and back on to get it to work. this problem nearly got me in an accident when it happened while entering a highway. also, sometimes in first gear the car will "chugg". it will struggle to accelerate and have a jerking/chugging feel. after a couple visits to hyundai, they have failed to figure out the problem. *tr
