2022 KIA EV6 Complaints

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 removed from the accelerator pedal. Doing this causes rapid deceleration beyond what would be considered normal for a driver approaching a turn or any other scenario where a planned stop will occur. Because the vehicle does not illuminate the brake lights during normal deceleration when using the one-pedal-driving feature of the regenerative braking system this significantly increases the risk of a rear end collision. The vehicle has been found to be operating normally and matches the behavior of other EV6 models. Although I have not yet been involved in a collision, I have been advised by other drivers that my brake lights are not working, and have had multiple 'close-calls' where drivers behind me have been unable to correctly determine that my vehicle is decelerating and have subsequently caused them to brake erratically or harshly putting myself and others at risk.

When heavy regenerative braking is used, the car decelerates very quickly. Despite this, the brake lights do not turn on. This is very dangerous as the regenerative braking can be used to completely stop the vehicle. People driving behind me need to be aware that I am coming to a stop and are not currently warned. Technology Connections just released a very detailed video on the Ioniq 5 which uses the same drivetrain as the EV6. https://www.youtube.com/watch?v=U0YW7x9U5TQ

The brake light does not activate in a way that would signal to other drivers that the vehicle is stopping or slowing down, while using higher regenerative braking. The ipedal mode can have a significant amount of deceleration and not activate the brake light, even coming to a full stop and not activating the light, if the driver's foot is not completely off the pedal. I have been told by other drivers that my brake lights were out when I expected that they were working. Testing this with a odb2 device and another driver following behind me confirmed that the Kia EV6 does not activate brake lights when it should. Additionally, there is a video on youtube titled "Electric cars prove we need to rethink brake lights", demonstrating this on a similar vehicle, the Hyundai Ioniq 5. https://www.youtube.com/watch?v=U0YW7x9U5TQ There is no indication in the vehicle that the brake lights are not functioning as a driver would expect. The lights do work when using the brake pedal and are not normally "malfunctioning". The nearest dealer has confirmed that the driver needs to take their foot off of the accelerator to actuate the brake lights. In my opinion, the vehicle should be recalled to apply a fix that signals braking and intent to slow down that is consistent with the deceleration of the vehicle.

The vehicle does not trigger brake lights when it is using Regen braking or the ipadel mode. This can cause a safety hazard for the person behind me to crash into me without the brake lights warnings

I was traveling on a neighborhood arterial road, when I heard a load thunk that seemed to come from beneath the rear seat. Moments later, I got a "Check electric vehicle system" warning, followed by "Stop vehicle and check power supply" in the dashboard. After another moment, the power was reduced to a maximum of 25 mph. I turned on the hazard lights because I was no longer able to match the flow of traffic (45 mph). No accident occurred. I was able to limp the car home on slower side streets. At home, I eventually got a "12v battery voltage low" message and the car was unable to move. I had to have the car towed to the dealership. The dealer service folks diagnosed the problem as a failed integrated charging control unit (ICCU). This same problem has been reported by others in the Kia EV forums. Kia Consumer Affairs says 87 of those parts are on backorder in the US with no ETA from Korea. Apparently, the part needs to be manufactured; they don't have them available in a warehouse.

I was driving my less than 1 year old, only 10,000 miles Kia EV6 First Edition when I got an error message to 'Check Vehicle Electric System'. After about another 2 miles I got a warning to "Stop Vehicle and Check Power Supply." As I attempted to find a safe place to stop, my vehicle started throttling my speed down to only 20mph (I was on a 55mph road). I was able to pull off and into a parking lot, but when I turned the vehicle off, it was completely dead and would not restart. Note, the battery was charged to 83% at the time of this incident. I had the vehicle towed the Kia Service Center at the dealership where I purchased the vehicle. After 5 days, they informed me that the ICCU had failed. Per their website, the Integrated Charging Control Unit, or ICCU, is a newly developed integrated charging system by Hyundai that charges both the high-voltage and spare batteries, essential to allowing for V2L (Vehicle to Load) feature. It has now been 20 days since the incident and Kia has no idea when a replacement part will be available.

On March 30, 2023 at 14k miles Integrated Charge Control unit failure of 2022 Kia EV6. Error message "Stop vehicle and check power supply." It was towed to the closest dealership. Kia customer care advised that the ICCU needed to be replaced, but the delivery date has yet to be confirmed.

On APRIL 23 2023. I GOT A CRITICAL WARNING MESSAGE ON MY CARS DASH PANAL. SAYING WARNING THERE IS A CRITICAL PROBLEM WITH YOUR CAR ELECTRICLA BATTERY. CALL ROADSIDE ASSISTANCE ASAP. ON APRIL 24 202E. I WAS ABLE TO GET MY KIA EV6 TO STOCKTON KIA FOR A DIAGNOSTIC TEST ON CARS ELECTRICAL BATTERY MALFUNCTION. THEY HAD MY CAR UNTIL 3:00 PM. THEY GAVE ME MY CAR BACK STATING THEY DONT KNOW WHATS WRONG WITH MY KIA EV6. THEY WOULD HAVE TO GENERATE A HIGHER LEVEL REPAIR REQUEST. BUT SINCE THERE COMPUTERS ARE DOWN THEY COULDNT REQUEST FOR REPAIR UNTIL SYSTEMS BACK UP AND WORKING. TODAY IS April 30 2023. Kia computer systems seem to still be down. I don't know if my car will explode, Burn, or just stop immediately in road Kia is not trying to fix my new kia problems. .

I have owned Kia EV6 since June 2022, the problem started in October and still have not been corrected. I encounter a problem with charging the vehicle at Level 2 charger of 40 AMP or higher. When charging at home Level 2, the vehcle send me email stating the charging has been interrupted. I have check the Kia forums and found that many other owner also have this issued. Currently, I have taken my vehicle to the dealership once and they states that there was no issued. After taking the vehicle home, at start to charge my vehicle the next day, the problem occurred again. I took the vehicle back last week and after 3 days that told me my vehicle was fixed. As i was going to the shop to pick up my vehicle, I got email notification again and I have show it to them that the problem has not be solved. The label does stated that we can used the charger up to 48 AMP. I have tested with different charger at different location and the problem is still the same. I will like NHTSA to look into this issue as this creates problem for car ownership of this type of vehicle.

The contact owns a 2022 Kia EV6. The contact stated that on various occasions while coming to a stop at a stop signal, a loud crunching sound was heard underneath the vehicle. The brake pedal was depressed, and the vehicle jerked forward. No warning lights were illuminated. The vehicle was taken to a local dealer however, the failure could not be duplicated. The contact stated that the failure reoccurred and caused the vehicle to lunge forward into oncoming traffic, causing another vehicle to almost crash into the driver's side. The vehicle was then taken back to the dealer and remained in dealer possession awaiting a further diagnostic test and repair. The manufacturer was not made aware of the failure. The failure mileage was 2,215.
