I bought it from Hyundai dealer on Dec 16, 2009 which only had 31000 miles then. It stalled three times within one week just one week after I brought. One stalling happened when backing up and one time happened when coming to a stop and one time when leaving a stop. I brought it to dealer on December 31,2009. Their report indicated that they found a code for random miss fire and they replace spark plug wires. Things temporarily went well after that. Then the car totally died on one morning, around Feb 10,2010. Then the car was towed to dealer service and dealer changed the battery. But the stalling problem came back this week and it had happened twice. One happened when turning around at parking lot and another was happened when turning around on local road. I am going to give dealer for another fix tomorrow.
