What 15 owners told NHTSA about the 2023 Kia Niro EV

Check electric vehicle system warning light indicator illuminates and car stops driving on highway! A/C and defrost won't work properly and when turned on causes the above warning light and malfunction. Car will not charge at "fast" charging stations and will leave you stranded on highway. I live in [XXX] and the vehicle only does it when humidity is high outside. Issue also causes problems with the 12V battery. SEVERE SAFETY ISSUE WHEN CAR SHUTS DOWN IN THE MIDDLE OF THE HIGHWAY DRIVING AT ANY SPEED. It is the system ICCU (Integrate Charge Control Unit) that KIA has a limited warranty coverage on and should be reviewed for recall. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

The vehicle is a rental vehicle. It experienced two incidents of sudden loss of propulsion within the first two days of operation. During both events, the vehicle became completely unresponsive to accelerator pedal input and would not move despite being placed in Drive. I attempted to shift the vehicle into Park and then back into Drive, but propulsion was not restored. No warning lights, malfunction indicators, or system messages were displayed before or during the failure. The first incident occurred while exiting a car wash. The vehicle became immobilized in an active traffic lane and would not respond to throttle input, creating an immediate risk of rear-end collision. Vehicles were approaching from behind and I narrowly avoided being struck. The second incident occurred later the same day in a parking lot while the vehicle was charging. Again, the vehicle became unresponsive without warning and would not move. The intermittent and unpredictable loss of motive power presents a serious safety hazard because it prevents the driver from maintaining control and safely operating the vehicle in traffic conditions.

I did an OTA update that made the rear view camera work intermittently. It would just flash an image every couple of seconds instead of a live stream. I took it into the dealer, and on the way, it totally gave out in the middle of traffic in a very unsafe way. I was flashed with many warning signs and was not able to get it started again for 5min by just turning it on/off again. I finally got it to the dealer and after 6 weeks they told me that something spilled in the cup holders and fried the backup camera and drivetrain components. I find it extremely off the drivetrain and safety critical components are stored under a cup holder with no protection.

While driving on freeway, at a speed of 65-70MPH. Vehicle appeared to lose power. Navigation screen turned off, dash display dimmed and vehicle seemed to coast and not accelerate. Speed did drop down a bit, but then powered came back on, screen turned on and was able to accelerate again. No warning lights or error messages appeared on screen.

The contact leased a 2023 Kia Niro EV. The contact stated that the vehicle failed to charge as designed. The message "Charge Interrupted" was displayed on the mobile app that monitored the vehicle. The vehicle was taken to the dealer, where the cause of the failure could not be determined; however, the failure persisted. The vehicle was taken back to the dealer. The vehicle was not diagnosed or repaired. The manufacturer was notified of the failure and a case was opened. The failure mileage was approximately 6,000.

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.

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.
