2023 Kia EV6

This issue has been persistent for at least 4 times a week for the past 4 months since getting the vehicle. The issue starts right after starting and driving the vehicle within about 5 mins after start-up the speakers start making an EXTREMELY loud/piercing abnormal sound while the vehicle is driving or even parked. I immediately have to pull over (while the loud noise is still happening) and turn the car on and over several time hoping the noise stops. The noise is extremely loud and abnormal static noise the entire time the issue occurs. The times it’s happened it would not stop for at least 15 mins, I try turning the car on/off and still won’t stop. This happens randomly and I am forced to pull over immediately while the extremely loud static noise is piercing my ears. There are no warnings prior to the issue occurring, just happens randomly. I’ve let the dealer know about this problem but they seem unfamiliar with the issue and don’t have a solution. We’ve tried updating the software and problem still occurs. According to forums this is a common issue with these vehicle but the dealer does not have a concrete solution.

When charging with L2 40A home charger vehicle gives a charging failed error. I live in Arizona where since the temperature has gone above 90 degrees in June the issue started. It will charge for a few minutes than fault. I have used this charger on other vehicles without issue. I need to change the vehicles charging settings ro reduced charging current for it to charge without error but this can take twice as long to charge on the reduced settings. I am convinced this is temperature related and the vehicle cannot charge high current in such extreme heat.

When using 1 pedal driving, it isn't necessary to use the brake pedal to stop the EV. The EV6 will only illuminate the brake lights when the accelerator pedal is completely released, or when the brake pedal is depressed. Since using 1 pedal driving does not require depressing the brake pedal to stop, the following vehicle has no indication or warning that the EV6 is stopping. I have experienced several instances of near rear-end collisions because of this dangerous issue with the Kia EV6. I emailed Kia asking if they were going to offer an OTA fix and this is their reply, " Dear [XXX], Hello, This email is to let you know that as of now we are not aware of any updates coming out for this feature. Your complaint will remain on file here within Kia for review. Sincerely, Kia America. Curiously Kia's parent company Hyundai, whose Ionic 5 has the same problem, is receiving a fix which will illuminate the brake lights while using the same 1 pedal driving programming as the Kia EV6. Because the lack of 1 pedal driving brake light warning to following vehicles, I have turned this feature off until the issue has been resolved. I hope NHTSA takes this dangerous situation seriously and provides legislation to force auto manufacturers to adjust the conditions when brake lights must illuminate.

I purchased my EV6 in April 2023, after 2 months, my charging abruptly stops, I will restart it and it fails minutes later. I have taken the car to the dealership 2x and they are unable to find the cause, I did further research and found an update that was applied on the second visit. This did not resolve the issue. I am having to drop the charging level down to "reduced" to get by. There are no warning messages on the dash or on the computer, at least none that Kia could find. There isn't a recall for this either. My concern is the safety of the car, due to the high voltage used to charge the car.

This car advertises that it is capable of fast charging on a level 2 charger up to 50amp. I purchased a level 2 charger capable of 50amps, but it causes the EV6 to overheat and stop charging. The dealership installed TSB ELE-283 but this does not fix the problem and is not an acceptable fix. I have owned this car 5 months, and it has been to the dealership service department 3 times for failing to charge. Kia has admitted that their dealerships don’t have the capacity to charge at the higher speeds, so they cannot replicate the issue and just keep giving me my faulty car back. While the expectation is that the car can charge at 48 or 50 amps, typically it fails at 40 amps and users are forced to reduce to 36 amps, which is not what was advertised. The Kia website advertises 11kW on-board charger (OBC) for Level 2 recharging from 10-100% in 7 hours, which is unachievable due to constant overheating. I have a ChargePoint home flex charger set at 48amps.
