The problem: The problem has to do with the integrated charging control unit (ICCU), which sends power to low-voltage vehicle accessories and the 12-volt auxiliary battery. It’s kind of like the alternator in a gas-powered car. Due to a manufacturing issue, the ICCU might fail while the vehicle is in motion. If this happens, drivers may hear a “pop” noise. The vehicle will display warning lights on the dashboard and sound audible alarms as the vehicle loses power. According to documents provided by Hyundai, drivers should have between 22 and 45 minutes to pull over safely before the vehicle totally loses power. Airbags, brakes, and power steering will remain operational.
The fix: Dealerships will replace the ICCU and its fuse, free of charge. They will also perform a software update.
How to contact the manufacturer: Owners may contact Hyundai and Genesis at 855-371-9460, and Kia at 800-333-4542.
