How reliable is the Kia EV6? What NHTSA's records show
We don't give the EV6 a reliability score. NHTSA publishes complaint counts but no sales figures, so complaints can't be turned into a rate or compared between models. Here is what's on file for model years 2022 on.

Every model year compared
Complaints rise with how many were sold and how long they've been on the road, so a newer or rarer year will show fewer. Compare years of the EV6 with each other.

The high voltage battery cells may contain misaligned electrodes, which can lead to a fire while parked or driving.
The Integrated Charging Control Unit (ICCU) may become damaged and stop charging the 12-volt battery, which can result in a loss of drive power.
The Integrated Charging Control Unit (ICCU) may become damaged and stop charging the 12-Volt battery, which can result in a loss of drive power.
One of the drive shafts may have been improperly heat-treated, allowing it to break under load and resulting in a loss of drive power.
A software error in the Shifter Control Unit (SCU) may disengage the parking mechanism, which can allow the vehicle to rollaway.

Was the work actually done on the car you're looking at?
Model-year records can't tell you about one car. A Kia service history check returns that vehicle's own dealer records by VIN.
Check a Kia's service historyCommon questions
Is the Kia EV6 reliable?
We don't score reliability: NHTSA publishes complaint counts but no sales figures, so complaints can't be turned into a rate or compared between models. What's on file for model years 2022 on: 544 owner complaints, 1 warranty extension and 11 service campaigns Kia filed, and 5 safety recalls. The model years with the most complaints are 2022 (278), 2023 (137), 2024 (76). Whether a known problem was fixed on one car is what its service records show.
What are the most common problems with the Kia EV6?
Across every model year since 2022, owners' complaints to NHTSA most often name electrical system (75%), fuel and propulsion (18%), transmission and drivetrain (18%). Kia has filed 1 warranty extension covering the EV6, listed on this page.
Which EV6 model years have the most complaints?
2022 (278), 2023 (137), 2024 (76). Complaint counts rise with how many were sold and how long they've been on the road, so compare years of the EV6 with each other rather than with other models.
Has Kia extended the warranty on the EV6?
Yes: fuel and propulsion (model years 2022–2024). A dealer does a covered repair for free within the extended time or mileage.
How do I check recalls on a EV6?
Enter the car's 17-character VIN at nhtsa.gov/recalls. That answers for one vehicle; the 5 recalls listed here are for the model, and each covers only part of it.
