There are 4 owner-reported fuel system complaints for the 2023 Kia EV6in NHTSA's database. These are unverified consumer reports and may not reflect confirmed defects.
While changing lanes on a freeway, the car passed through a narrow strip of slush from recent snowfall. The car immediately disabled the motors, preventing acceleration and regenerative braking for nearly 50 seconds. There were no warning lights, sounds, or messages displayed on the car's gauge cluster display, either for the initial loss of propulsion or for the restoration of propulsion. This caused a loss of traction when the car eventually passed through a patch of packed snow and ice.
Was parking car. Pushed on brake and car accelerated
Vehicle was normal and during the drive a warning light for "Check Electric Vehicle System" was shown, then a second warning light "Stop Vehicle and Check Power Supply" was shown, within 2 minutes the vehicle went into "turtle" or reduced speed mode and then finally the vehicle shut down completely. I was on city streets at the time and was able to park safely, but if this had happened on and interstate highway it would have been dangerous. This is a known issue with this vehicle as it ended up being an ICCU Assembly failure. There is also a safety recall for this, but Kia is not replacing the part and just doing a software update that is not fixing the root cause of the problem.
1. **Battery Pack Issues:** - The vehicle's battery pack experienced issues at DC Fast Charger and all charging levels, available for inspection. 2. **Safety Implications:** - Range anxiety began on December 11, 2023, with the vehicle serviced on December 22, 2023, and again on January 10, 2024, for low range due to battery pack issues. On January 8th, stranded for 3 hours in cold weather with 3 miles of range, posing a significant safety risk. 3. **Confirmation by Service Center:** - Two services conducted on December 22, 2023, and January 10, 2024, documented battery pack issues. The manufacturer attributes it to weather without a prior warning upon selling. 4. **Inspections by Others:** - No inspections by the manufacturer, police, or insurance representatives at this point specifically for the battery pack. 5. **Warning Signs:** - Range issues causing anxiety started on December 11, 2023, well before any service. Services conducted on December 22, 2023, and January 10, 2024, didn't significantly improve battery pack performance.
