Consumer Description

Engine stalled and there was a loud knocking sound. Had vehicle towed to dealer only to be told that this is a known issue with Hyundai and we need a new engine. No loaner cars available and 36 people are in front of me with the same problem. No timeframe available for a resolution. Huge inconvenience. Called Hyundai only to be told that a case manager would call me in 7-10 days. If it’s a known issue, why haven’t they recalled the affected cars like last time?
