Kia EV9 Battery Woes: Owners Face Long Waits

Kia's flagship EV9 is experiencing significant battery issues, with owners reporting a range of problems from dead 12-volt batteries to failures in the main high-voltage battery pack. These issues have led to charging failures, where cars stop charging at 82 percent and then rapidly jump to 100 percent without gaining actual range. Many owners also report a substantial decrease in estimated range at full charge. Some UK-based EV9 owners are facing wait times of up to nine months for battery repairs, causing considerable disruption and financial strain.

These problems are not isolated to the EV9; Kia and its sibling brand Hyundai have faced similar issues across various EV models, including Integrated Charging Control Unit (ICCU) failures, which can cause a dangerous loss of power while driving. Both manufacturers have recently begun extending warranties for affected vehicles after years of silence on the matter. Consumer reports indicate that a significant percentage of Hyundai and Kia EV owners have experienced ICCU-related problems.

Owners are advised to use OBD II scanners to check their vehicle's battery health, as dealerships may not always identify the issues. Documenting these failures is crucial to pressure the Hyundai Motor Group into addressing what appears to be a growing battery failure problem across their electric vehicle lineup. Some owners have reported faster repairs, possibly due to preferential treatment, while others endure prolonged periods without their vehicles.
