Things to check

US recall 26V-431 (July 2026): some 2022-2024 EV6s have battery cells that may short and catch fire. Until Kia replaces the battery, park outside and charge to 80% at most. Check the VIN. api.nhtsa.gov
The high voltage battery cells may contain misaligned electrodes, which can lead to a fire while parked or driving.
US recall 24V-867 replaces 24V-200 for the ICCU (the unit that charges the 12-volt battery). A failed ICCU can cause loss of drive power. Cars fixed under 24V-200 need the new fix too. static.nhtsa.gov
Vehicles previously repaired under recall 24V-200 will need to have the new remedy completed.
UK recall R/2024/197: EV6s built April 2021 to February 2024 get an ICCU software update, or a new ICCU and fuse if a fault code is stored. Check it was done. check-vehicle-recalls.service.gov.uk
The Integrated Charging Control Unit (ICCU) may become damaged over time and may not be able to charge the 12-volt battery
From the 2025 US model year (UK: late 2024) the EV6 has a bigger 84 kWh battery. This page covers the 77.4 kWh car only. lloydmotorgroup.com
Battery capacity 84.0kWh 84.0kWh
UK recall R/2026/309 (August 2026): an EV6 built September 2021 to January 2024 may have battery cells that can short and catch fire. Kia replaces the module, or the whole pack if battery health is 90% or less. Only 1 UK car is listed; check the VIN. check-vehicle-recalls.service.gov.uk
A misaligned electrode may over time result in an internal short circuit in certain situations thereby increasing the risk of fire.

"Estimate" means we worked the figure out or borrowed it from a similar car; open "What the source covers" to see how. Expected health is a straight-line estimate from fleet data, not a test of any one car.
