Safety risk
Polish automotive trade outlet reporting Kia's EU service campaign for EV6/EV9 high-voltage batteries.
What to check. Confirms the battery fire-risk issue reached the EU market: a Polish service campaign (code 261334) covers EV6 (CV) and EV9 (MV) built 2021-2024. An EU buyer should check whether a specific EV6 is included via Kia's campaign lookup, since not every unit in that window is affected.
Class-action lawsuit alleges Kia EV6 ICCU recall did not fix the defect
CarScoops reporting on a class-action lawsuit over repeat ICCU failures.
What to check. Owners allege the ICCU recall remedy did not stop failures — replacement ICCUs may fail again, causing 12V battery drain, limp mode, and total power loss. This is litigation, not an official finding, but it signals the ICCU problem may persist after the recall fix.
