2022 Kia Niro EV electrical 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)

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.

Car has broken down, not started, battery dead when fully charged MULTIPLE TIMES. It has been in the Kia service department since March 2024 (9 months) and they can’t figure out where the parasitic drain is from. This is the third time this year getting towed to the Kia dealership with no resolution. No warning lights / labels prior to failure. Danger by leaving me stranded 3+ times this year with need for triple A.

I received a recall notice for my 2022 Kia Niro EV regarding the safety plugs of the high-voltage battery. I have now scheduled three different appointments with Kia of Lincolnwood to perform this recall, and each time I have been turned away with a different excuse (lack of part, lack of tools, performing recall will take too many hours). The last time I asked to speak with the service manager, who assured me he would take care of this and I would be able to come in on Friday 10/11. Given how many times I've been turned away, I called the day before to confirm, and the manager said he would call me back and never did. Repeated attempts to contact him or the dealership that day went unanswered. I would like help getting this dealership to perform the recall. Given the risk of fire or crash, I am not comfortable driving this vehicle or charging it. I am attaching copies of both the recall and the last work order I was given, where it shows once again I was asked to come back another day.

In re: Manufacturer Recall Number SC314, the federal safety agency Recall Number 24V358 The Kia dealership (Aloha Kia Leeward, Waipahu, Hawai‘i) is imposing an unreasonable delay for this safety recall. Dealer was contacted in mid-July to schedule recall service. Dealer said it had to order the part. After not hearing from the dealer for two weeks, dealer was contacted on August 2 and recall service was scheduled for August 27 (claiming that was the first available appt.) Dealer kept the vehicle for 5 hours that day, then said the service could not be performed. Dealer said it would contact me to reschedule. After leaving messages and not hearing back from dealer, I went in person on 9-4-24. Dealer could not schedule recall service until October 7. Because this is a recall for safety issues, this repeated delay is unacceptable. I wish to put this complaint in the record regarding the disregard for vehicle safety by Aloha Kia Leeward of Waipahu, Hawai‘i. Thank you.

Started 2-3 months ago and is progressively getting worse. Battery drop from charged down to 2% randomly. Battery would drop 1% every 3 seconds. During highway drive it would cancel out cruise control and/or limited power down to 30mph. Which almost caused accident for the sudden loss of power. Brought to dealer and found no issues, waiting for next appointment in 2 weeks (next opening) to bring in for second look. Currently renting a vehicle since it is life threatening to just have no power in range and acceleration.
