What changes compared with the 2025 Kia EV3
The same engines and the same documented faults as in 2025.
Faults outside the engine in the 2026 Kia EV3
- High severityFrequency: CommonElectrical systemICCU fault: interrupted charging and car immobilisedThe EV3's ICCU (on-board charger, V2L and the converter that recharges the 12 V battery) has failed on a number of 2024-2025 units, causing charging cut-outs and stranded cars. Kia repairs it under warranty by replacement, with parts waits of several weeks.
- Medium severityFrequency: OccasionalElectronics and infotainmentRecall for a delayed digital instrument clusterIn April 2026 a recall was published in Germany (KBA 16442R) because the digital cluster may react late to speed or warnings. It affects cars built between 24 June and 18 December 2025 and is fixed with software.
- Medium severityFrequency: RareElectrical systemCoolant leak from the valve housing under the expansion tankSeveral 2026 EV3 owners report coolant leaks from a valve housing located under the expansion tank, and warnings from the motor cooling circuit. Kia replaces parts under warranty; there is no campaign.
- Low severityFrequency: OccasionalElectrical systemAC charging that drops in powerIn cold climates, AC charging on the EV3 starts at around 10-11 kW and drops to 4-7 kW (and occasionally to about 2 kW) after a few minutes, nearly doubling charging time. Kia has published several ICCU updates, without confirming that they fully fix it.
- Low severityFrequency: OccasionalElectrical system12 V battery discharge and wireless CarPlay faultsSeveral EV3 owners describe the car not starting after being parked, due to low 12 V battery voltage (one measured 11.9 V), plus freezing of wireless CarPlay. It was resolved with warranty batteries and battery management updates.
