2022 Kia Niro EV problems

Filed Oct 23, 2026 · Electrical, Engine · MD

On XXX, After I attempted to plug my car into my home charging outlet at 240V, less than 20 minutes later I received an alert that my battery was at 0%. After unplugging the car, waiting for 30 minutes and plugging it back into the out, my car was unable to see the charging outlet or the 40A cable plugged into the port. Unplugged car again and after talking to remote mechanic, came to decision to take car to AAA repair shop for troubleshooting. Once at the AAA repair shop in [XXX], was advised to take my car to a Kia dealership, as a module was nonfunctional. Brought car to Beyer Kia in [XXX], who held onto my car for two months before making a diagnosis that my car was struck by lightning via a Field Technical Engineer, though the DTC codes stated otherwise: C180287, C161487, C16b487, C161487, C161487, C182D00. All codes noted are internal Controller Area Network Bus Communication Timeouts between internal modules, not power surge or electrical strike. C161487 - registered three times: Internal network timed out because VCU abruptly went offline or lost power. With it registering 3 times confirms ongoing hardware/power supply struggle inside car's computers, not external bolt of lightning. C16B487 - Another subsystem critical timeout error, unable to communicate with VCU. C180287 - Internal stability/chassis lost data connection over vehicle's internal network. C181D00 - Network fault indicating control module voltage dropped below required operating threshold to maintain communication. Kia is trying to claim an external surge (lightning) caused this. However, if a massive high-voltage lightning surge had entered the vehicle through the charging port, it would have permanently fried the OBC (Onboard Charger) or the ICCU (Integrated Charging Control Unit). This would immediately trigger high-voltage hardware failure "P-codes" (Powertrain). INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

I purchased this used 2022 Kia Niro EV on August 19, 2023, with approximately 3,042 miles. On December 22, 2023, at 24,086 miles, a Kia of Valencia service record documented a kicking/knocking sensation when releasing the brake. The cause was not identified. On August 22, 2024, another service record documented a rear seat belt retraction concern. I cannot confirm whether these earlier problems share the same cause as the later motor issue. On March 31, 2026, at approximately 139,071 miles, Kia of Valencia confirmed a rattling noise from the gear driver motor and recommended replacement. The estimated repair cost was approximately $4,800. I paid a $250 diagnostic fee but could not afford the repair. I contacted Kia America to request goodwill assistance, but the motor was not replaced. On September 9, 2026, while driving on a freeway in heavy traffic, the vehicle repeatedly stopped and moved again, accompanied by extremely loud knocking, rattling, and banging. The vehicle shook, and no warning lights or messages appeared beforehand. I carefully exited the freeway and stopped the vehicle. After bringing it home, I noticed liquid underneath, but could not determine whether it was related to the incident or normal air-conditioning condensation. I have video recordings and supporting service records. I am concerned that this unresolved mechanical problem poses a serious crash risk, especially in freeway traffic. I request that the federal safety agency investigate this potential safety defect and review the documented rear seat belt concern.

Component or system that failed: High-Voltage Electrical System / High-Voltage Battery Safety Plug Assembly (specifically covered under Recall SC314 / the federal safety agency Campaign 24V‑358). It is NOT wear and tear as falsely claimed by the dealer. The vehicle is available for inspection upon request at the owner's residence. How safety was put at risk: The vehicle triggers an active "Check EV System" master warning while driving, creating a severe risk of sudden loss of motive power (stalling) on public roads. The high-voltage charging system is also completely disabled, leaving an elderly driver stranded without transportation. Has the problem been reproduced or confirmed by a dealer?: Yes. Rick Case Kia (Duluth, GA) inspected the vehicle from July 20–22, 2026. Instead of resolving the recall defect at $0.00, they falsely mischaracterized the electrical failure as "wear and tear / customer declined repair" and demanded $1,617 out-of-pocket before releasing the unsafe vehicle. Has the vehicle/component been inspected by others?: Inspected by [XXX] Case Kia service department. Opened active corporate case with Kia America (Case #XXX). Independent mechanics have confirmed this is not simple “wear and tear”, but deeper electrical issues that were touched during the recall. Warning lamps, messages, or symptoms: "Check EV System" master warning light and total failure of the high-voltage charging port. Symptoms first appeared shortly after initial Recall SC314 service was performed on June 15, 2026, and worsened prior to returning the car on XXX. Kia claims to have completed Recall SC314 on June 15, 2026. However, the recall work directly triggered immediate secondary failures in the high-voltage charging system. The dealership is now attempting to evade liability for recall-induced damage by labeling it 'wear and tear' and demanding $1,617 to fix a failure caused by their own recall service.

COMPONENT/SYSTEM: The 12-volt auxiliary battery system, the interior fuse box (Total Integrated Power Module) containing an auto-cutoff relay, and the high voltage battery system. All components are available for inspection. SAFETY RISK: The vehicle has lost power and died while being driven, and has left occupants stranded on multiple occasions. A sudden loss of motive power in traffic creates a serious risk of collision to occupants and to other motorists. The vehicle has failed to start dozens of times. FAILURE DESCRIPTION: The 12-volt battery in my 2022 Kia Niro EV has repeatedly discharged, leaving the vehicle dead and unable to start. ~Six 12V batteries have been installed between January 2025 and February 2026, between 60,431 and 77,130 miles. CONFIRMED BY DEALER: Yes. The condition has been reproduced and documented by the dealer across five separate repair orders. On 1/21/2025 at 60,431 miles, the technician found the 12V battery completely dead after sitting, jump-started the vehicle, and reported no abnormal draw on the electrical system. On 11/05/2025 at 74,355 miles the vehicle again required a jump start to be brought into the shop; the battery was replaced, and the technician reported the vehicle was operating as designed. On 1/22/2026 at 77,124 miles, a technician performed a parasitic draw test and measured 0.185 amps, exceeding the specification of below 50 milliamps by approximately 3.7 times. The technician documented that the auto-cutoff relay was remaining closed, continuously supplying current to 21 modules, and that the interior fuse box required replacement at a quoted cost of $2,048.48. This defect was present during the two prior visits but was not identified. On 2/13/2026 at 77,130 miles, the vehicle would not start when we came to pick up the car. The shop had to provide a loaner, and then another battery was installed, and the TIPM was replaced.

I wanted to go to the store and when I pressed the Start button I got the message: Stop car and check regenerative brakes. Soon after the lights dimmed and the message showed up that key fob was not detected even though it was in my hand. It then no longer took a charge and is completely dark. I checked the internet, and it sounds like it is the 12V battery and is a known issue that is not yet at recall level.

I have had this vehicle for 13 months and have taken it to the shop 4 times for the same reason. The 12v dies and my car has to be Jumpstarted in order for me to use the vehicle. Dealer usually blames the 12v at the beginning of the appointments before ultimately telling me there is nothing wrong with the 12v and that they are unable to replicate the problem. They rarely go beyond preforming a drain test, despite me telling them that there is no drain. I've been stranded late at night because of this issue, and now keep a portable jumpstarter in my vehicle at all times.

I bought my 2022 Kia Niro EV new in 2022, and around 40,000 miles, I had a problem with the reduction motor so I replaced it, shortly after that I had a problem with the wheel so I replaced a part called the axle, and shortly after that, the other wheel had the same problem so I replaced the same part, and the Kia employee said that this part only breaks if there is a strong impact (traffic accident) so it's strange. All of this happened in less than 2 years but I had it covered under warranty so I got it fixed, but now the reduction motor problem that I had originally replaced has happened again and they are demanding $5,800 to repair it since it's out of warranty. I think this is unfair, and this is the first time I've had a car with this many problems in less than 3 years.
