I had an issue in early June regarding my 2008 Hyundai Elantra. Car began to hesitate and stalled out. It was told back to dealership, which could not recreate the problem and informed me it was a fuel injection misfire, rebooted computer and said it would not happen again. On July 3rd, I had the exact same situation occur on my trip while driving on I-95 to visit family in delaware. Dealership in delaware on July 7th informed me I had a defective fuel pump and replaced it on July 8th. Leads me to believe that was problem in June and dealership I purchased car from did not investigate the problem properly.
