Battery Electric (BEV)
Battery & propulsion complaint analysis for the 2022-2025 Kia EV6
That's roughly 7.8x the typical rate for BEVs in this dataset (median 5.5 per year). This generation has materially more battery & propulsion complaints than its peers, even after accounting for sales volume.
What kind of battery complaint?
Among the 217 battery-related complaints, here's the type mix. These percentages describe what the complaints are about — not how reliable the vehicle is overall.
Low-voltage battery deaths, common on EVs and hybrids that use a 12V for accessories.
Loss of power, drive unit, inverter, traction motor, DC-DC converter.
Propulsion battery defects, capacity loss, BMS faults, replacement claims.
Charge port, cable, mobile connector, or session failures.
Regen brake feel, one-pedal driving, B-mode complaints.
Hybrid system warnings, eCVT, motor-generator, hybrid transaxle.
Sample complaint excerpts
12V Auxiliary Battery
- [2022] Electrical propulsion failure resulting in 3 tow-ins. Vehicle goes into limp mode, slows to 20 mph on highway and then stops after about 2 miles. The issue appears related to the ICCU, fuse and 12V battery failures. History includes 6 attached ICCU related Repairs. #1 ICCU updated under recall SC271 at 31,678 miles. #2 Then the ICCU was replaced under recall SC302 at 45,059 miles. #3 Then t
- [2022] A warning came up on the dashboard to “Check electric vehicle system”. 12v battery light also on. Vehicle went into limp mode and drove at 45 mph max for a period of time, then dropped to 27 mph max. Inspections at Ziegler Kia in Holland, MI, found the ICCU was faulty and needs to be replaced. This vehicle has already had the ICCU recall applied, yet ICCU has failed again.
- [2022] Persistent ICCU failure causing charging interruptions, “Check Vehicle Charging System” → “Stop vehicle and check power supply” warnings, low 12V battery voltage (down to 12.1V), and risk of power loss/strand. Kia Connect sent “Charge Interrupted” alert during a session that reached 99%. Multiple prior recalls/attempts failed to resolve (Sep 2023 TSB ELE291 BMS, Jun 2024 SC271 ICCU SW, Jan 2025 SC

- [2022] In November 2024, my 2022 Kia EV6 became suddenly non-drivable due to electrical failure consistent with a repeat ICCU/12-volt system malfunction. The vehicle would not start or maintain normal electrical power and became stuck in accessory mode, creating a loss of propulsion and complete loss of transportation. This vehicle previously experienced an ICCU failure earlier in 2024 that required dea
Charging System
- [2022] When attempting to level one charge the vehicle at home, the car returned a failure to charge error and would not charge. This was attempted several times using different outlets and the same error occurred. The car was brought to Gettel Kia in Bradenton Florida. The dealership confirmed that the ICCU had failed,. They did not have the part and apparently it is on backorder. The repair is being c
- [2022] Incident occured october 17, 2024. Was driving approximately 30mph on a local road when lights flashed to "check electric vehicle system". Was speed restricted to 25mph (on 45mph road) and was able to make it back home approximately 1 mile away. Car completely shut down in my street prior to making it to my driveway. It needed to be towed to the nearest dealership. No lights in dash working and fl
- [2022] This electric vehicle failed to charge at level 2 charger at home. It charged at level 3 fast chargers however it registered a full charge at 125 miles and the level of charge in % and miles remaining fluctuated with sudden shifts. There were no warning lights or other signs of problems. I took it to the dealership who wanted me to keep driving and wait a week for an appointment. I knew that thi
Regenerative Braking
- [2022] There exists a serious manufacturing defect in that the brake lights do not turn on when the car is used in one-pedal drive mode and even a rapid deceleration occurs due to regenerative braking. This was documented by Consumer Reports and it presents a critical safety hazard. https://www.consumerreports.org/cars/car-safety/brake-lights-can-fail-to-provide-fair-warning-on-some-evs-a9533519285/?EX
- [2022] Brake lights do not illuminate when using the Regenerative Braking System in the Kia EV6. The vehicle is fitted with a 'one-pedal-driving' system that allows the vehicle to slow down and stop without actuation of the brake pedal. When using this system, the vehicle can decelerate rapidly and to a complete stop, however the brake lights do not illuminate unless the drivers foot is completely remov
- [2023] Component/System Failure: The i-Pedal feature in the Kia EV6, designed for one-pedal driving through regenerative braking, consistently fails to stay engaged. This component is available for inspection upon request. Safety Risk:The erratic behavior of the i-Pedal function poses a significant safety risk. When the i-Pedal mode disengages unexpectedly, drivers must abruptly switch to using traditio
Hybrid Drivetrain

Source: classified from NHTSA complaint and recall data. "Battery-related" includes high-voltage propulsion battery, charging system, hybrid drivetrain, electric propulsion, regenerative braking, 12V auxiliary battery, and thermal-event complaints. Other complaints (suspension, steering, brakes, infotainment) appear in the engine and vehicle-level sections. Rates are absolute counts, not normalized per-VIN — high-volume models naturally produce more raw complaints than low-volume ones. Self-reported death and injury counts are capped per complaint to limit form abuse.
