2023 KIA NIRO EV — Complaint #1963385

Open-data reference.

NHTSA Complaint about ELECTRICAL SYSTEM:PROPULSION SYSTEM:CHARGING:CABLE/CORD:ACCESSORY filed January 31, 2024

NHTSA complaint #1963385 (ODI reference 11569149) concerns a 2023 KIA NIRO EV and was filed on January 31, 2024. The owner reports the failure occurred on October 5, 2023. The report was geocoded to Texas based on the filer's self-reported location. The affected component is categorized as electrical system:propulsion system:charging:cable/cord:accessory, one of NHTSA's standardized taxonomy codes used to group defect patterns across make, model, and year.

The filer flagged the following severity indicators: crash: no, fire: no, injuries: 0, fatalities: 0. No crash, fire, or fatality was associated with this report, which places it in the early-warning stream rather than the priority-review stream. Because a VIN was supplied, this complaint is tied to a specific vehicle and not just a model-year cohort.

Individual complaints are consumer-submitted and unverified by NHTSA engineers — the agency's role at this stage is to collect, index, and make them searchable. What matters for federal action is the pattern: when many owners of the same KIA NIRO EV cohort independently describe similar electrical system:propulsion system:charging:cable/cord:accessory failures, defect investigators have grounds to open a PE and request manufacturer data. Related filings for the same vehicle and component appear below, and the detail page for the full 2023 KIA NIRO EV shows the complete component-level complaint distribution alongside any active investigations or recalls.

Complaint Description

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 time
