Purchased 2010 Hyundai Santa Fe in Feb 2010. Drove to dallas, tx in May 2010 the car started stalling after being idle at traffic light, on turns and from pulling out after being stopped. You would the think it was going dead but would catch up. This occured numerous times during the trip to & from. Immediately took to dealership on return but they found no problems. Has happened numerous times since then, once at 20 mph mergeing in traffic and twice today. Have taken it in 3 times but they never find anything and could not duplicate problem. I don't know when this will happen and don't dare pull out in traffic unless I have plenty of clearance from other cars! I feel at risk everytime the car in driven and feel it is a very dangerous safety problem and needs to be investigated.

On Tuesday, June 8, 2010 I was on a busy interstate highway with fast moving traffic and my car lost all power while traveling at 70 mph. Fortunately, I was able to barely glide the sante fe to the shoulder and stop without incident. Follow up: 3 pm visited Hyundai service center and was told that it was not a throttle problem. They are in contact with ca service to determine cause of problem. Friday, 6-11-10 after complete testing of all circuits, Hyundai declares no source of problem. Auto was picked up at 4:30 pm Hyundai assistant service manager: Bob wood Hyundai case # 3982284 the specifics are: "SUV was purchased 8/09 and currently has 5200 miles. ?cruise control was on but not engaged. ?gas tank indicator on one-half. "with my foot on gas pedal the initial instinct was that the engine had lost all power. Opressing harder on gas pedal had no reaction. Othere was an opening in traffic and with the SUV forward inertia I was able to just reach the road shoulder. Oobserved that red indicators were on (battery, oil) ?reset transmission selector to park, turned off key. Ofirst restart-nothing happened osecond restart SUV started and I did not turn off until reaching home. Obviously, this is a serious life threatening situation that needs to be researched thoroughly and corrected.
