Question 1

What is Reduction Gear Noise on the Hyundai Kona Electric?

Accepted Answer

A "clicking" or "tapping" sound that increases with speed can indicate a problem with the reduction gearbox or motor bearings.

Question 2

What is 12V auxiliary battery drain on the Hyundai Kona Electric?

Accepted Answer

The small 12V battery that powers ancillary systems can drain within days of inactivity, leaving the car completely dead despite a full main battery. The standby draw depletes the 44Ah battery quickly, and repeated deep discharges shorten its lifespan. A BMS software update (TSB 24-01-090H) addresses the worst drains, but some owners still carry a jump pack.

Question 3

What is High-voltage battery fire risk (recall) on the Hyundai Kona Electric?

Accepted Answer

Approximately 77,000 Kona Electrics worldwide were recalled due to battery cells manufactured at LG Energy Solution's Nanjing plant. A folded anode tab could allow internal short-circuiting and fire risk. Over a dozen fires were reported globally. Hyundai replaces the entire battery pack free of charge under recall — cars built with SK Innovation batteries at the Czech Republic plant were not affected.
