Common Problems with 2024 Hyundai IONIQ 6
ICCU failure strikes the 2024 Hyundai IONIQ 6 most often. This part fails and stops charging the 12V battery. Drivers lose power suddenly. The car might stop in traffic. Hyundai recalled 99,055 vehicles. Dealers replace the ICCU, fuse, and update software at no cost.
12V battery problems happen a lot. The battery drains fast. The car switches to a low-power mode with limited speed. Owners call for roadside help often. One owner had to jump-start it twice in a few months.
Tire pressure warnings pop up daily. Alerts appear with no real issue. Pressure readings jump around. Resets do not last. The 21-inch wheels and heavy car wear tires fast. Some owners report blowouts.
Software bugs annoy drivers. Updates create new problems. Alerts keep coming. Beeps sound for tiny issues. The infotainment screen freezes. Menus take extra clicks. Voice commands do not work.
Four recalls point to safety issues. Loose bolts on the differential gear cause power loss or lockup. This affects few cars but raises crash risks. Hyundai replaces the gear drive unit for free. Check your VIN on NHTSA.gov for all recalls.
Owners notice these issues early. The ICCU recall began in 2024. Fixes started by April. Some cars need work again. Hyundai changed designs for 2026 models.
