2023 KIA NIRO EV Complaints

The vehicle is usually charged on a level 2 system set to 40 amps or 9 KW/hr. In October of 2023, I received the following message from the Kia connect application, "Charge Interrupted". The car disconnected electrically from the wall unit/charger because the connector unit in the car where the cable plugs into or internal charging unit was getting hot. This "charging interrupted" is a known issue with Kia and Hyundai electric cars so much so that they have issued a Technical Service Bulletin SB, ELE288 which reprograms the car charging logic for level 2 charging. The TSB dramatically slows down the charge rate (from 9 KW/hr to 5 KW/hr when the connector or charging unit gets hot through normal charging. The net effect of this TSB, work around has doubled the time required to charge at the level 2 rate indicated in the owners manual (Page 1-17). Kia needs to address this problems via a hardware fix rather than covering it with a software work-around which doubles level 2 charging times by reducing the charging rate. I bought this electric car under the impression from the manufacture that it could charge to its battery 0-80% in 6-7 hours. The new reality of the TSB fix for overheated charging components is a 12 plus hour recharge to 80%. The TSB fix for overheating components is reducing the value and the utility of my new car. Please investigate this issue as it also shows up in the Kia EV6, Hyundai Ionic 5 and 6, as all cars are probably using the same connector design or sharing parts.

I had front collision that caused by having difficulty switching my foot from acceleration pedal (gas pedal) to brake pedal, my foot movement from gas pedal to brake pedal has been restricted by friction between my shoe and brake pedal that delayed my foot movement and caused the accident, Automatic emergency brake did not function too. Also air bags did not open at this front collision.

The car continues to not be able to charge at home. My other electric car (different manufacturer polestar) with the same cord charges without issues. The cord only allows 27amps and the car abruptly stops charging over and over. I have to reset it constantly. This continues to be an issue and the car shows no problems with the battery and there is no fix from Kia.

Charge Interruptions session. The Kia Niro EV interrupt charging on a Level 2 50amp ChargePoint Home Flex charge. I contact the Charger company ChargePoint and reduce the power to 40 amps. The car charging improve slightly but continue interruption. The on board CSS J1772 port of the car overheat and stop charging. Same issue that the Ioniq 5, Ioniq 6, Kia EV6, and Genesis EV.

There have been days where the weather starts out to be low to no rain or snow and then while driving from Kenosha, WI to Milwaukee, WI the rain or snow gets heavier or mild and the smart cruise control will stop and say radar blocked and it will disable the use of it and disable regenitive braking as well. So if you are driving doing 70+ the speed limit on the interstate all of a sudden it will terminate without any warning and now all of a sudden the car behind you is in your truck space so you have to excellerate extremely to avoid getting hit. THis is a extreme safety hazard.
