Consumer Description

ICCU failed second time wednesday february 18, 2026. First ICCU failed November 2024 and replaced under warranty. The car went in turtle mode.....20 mph or less. Limped along safely on side of roadway and used sideroads. The dealer says the ICCU and fuse need to be replaced. The dealer wants me to pay for this part, third time is a charm? I don't think I could ever trust this part again. They want to give me the exact same part they gave me when the ICCU failed b4. There were 2 messages: stop vehicle and check power supply ......check electric vehicle system. They were timely and made this failure a bit safer. The dealer inspected the vehicle but not the manufacturer or anyone else. The car is at Balise Hyundai Fairfield CT I BELIEVE 10% OF THESE ICCUs ARE DEFECTIVE.
