Kia Ev6
Problems & Worst Years
Every reported problem for the Kia Ev6, model year by model year — ranked from 215 federal NHTSA complaints across 2022–2023.
Charging hardware, not the battery pack itself, is the recurring theme across the EV6's two model years in this data. In 2022, the nameplate's launch year, Integrated Charging Control Unit failure was the top-reported problem at 67 occurrences out of 261 total, followed by battery charging issues more broadly (47) and a separate 12-volt battery failure (37) — the small auxiliary battery that, when it fails, can leave an EV unable to start even with a full main battery. Vehicle suddenly losing power and unintended deceleration due to loss of motive power, both electrical-system complaints, added 20 and 16 occurrences respectively, underscoring that the charging and power-delivery electronics were the launch year's central weak point.
The 2023 model year shows the same failure mode persisting at lower volume: ICCU failure again topped the list, logged twice under slightly different titles for a combined 36 occurrences out of 99 total, with electrical warning lights and errors, battery voltage drop, and another 12-volt battery failure complaint filling out the rest of the top five. None of these top five 2023 complaints carry a safety-severity tag, though one problem elsewhere in that year's wider list does — a modest increase from 2022, when zero complaints of any kind were flagged safety-severity despite the higher overall volume.
Recall coverage reflects the same pattern: 22V322 applies specifically to 2022, while 24V200, 24V867, and 26V431 span both model years, indicating Kia issued follow-up remedies well after each vehicle's original sale.
Between the two years, 2022 carries both the higher volume and the more varied set of charging-related complaints, while 2023 looks comparatively calmer — though it has also had less time on the road to accumulate reports, so that gap shouldn't be read as a fully resolved issue. A buyer looking at either model year should ask specifically about ICCU replacement history and confirm all three recurring recalls have been completed, since that service record will say more about an individual car's condition than the model year by itself.
