My 2023 Kia EV6 was subject to recall SC327 (the federal safety agency 24V‑867, ICCU); the recall remedy on Nov 19, 2024 was an inspection and software update only. After the remedy, the car repeatedly lost all 12-volt power (Feb 2025 and Apr 2025). Each time, the dealer said it could not find the cause — its hands were tied, it said, because Kia corporate required a diagnostic code and some codes did not yet exist for a car this new — and it repeatedly replaced parts, including the 12V battery twice and the battery sensor, to "hope for the best." On May 12, 2026, while driving about 25 mph, I heard a loud pop/bang from under the car, an electrical warning appeared, the vehicle lost power and stopped in traffic, and would not shift out of Park or move. The dealer found the high-voltage box exploded, all high-voltage fuses blown including the 500-amp fuse, the power relay assembly shorted, and connectors damaged by heat; about $16,324 of high-voltage components were replaced under warranty. The dealer and Kia engineering could not determine the cause; the service advisor wrote on July 22, 2026: "We do not have a smoking gun as to what caused all of this… anything is all a guess." On Oct 17, 2026 I found the car completely dead again at the dealership, and it has continued to show electrical faults. After I retrieved the car on Oct 26, 2026, it developed further electrical faults, which I reported to the dealership in writing, including the mirror and remote start failing, false door-unlocked warnings while driving, and two occasions when the car stalled and then recovered. On Nov 2, 2026, the car displayed a charging fault and would not charge at all; the dealership's general manager advised me in writing to discontinue charging attempts until the vehicle is evaluated. The dealership has repeatedly declined to state that the vehicle is safe to drive. I am concerned the vehicle is unsafe and that the recall remedy has not corrected the defect.

What 2023 Kia EV6 owners say
Most recent owner complaints, unedited.
Vehicle failed to start and a jump is required to start the vehicle for the first time on 10/6/2026. This has now happened numerous times and at times when the vehicle's power train batteries are charged. An small portable charging device has been purchased to jump the vehicle which eliminates the need to call for roadside assistance. Roadside assistance has take over 2 hour to response. An error on the dash indicated the 12 Volt battery has lost charge. There is a red circle message displayed on the dash. The vehicle was taken to Batteries Plus and a battery and alternator test. No problems were noted. The vehicle is scheduled for a dealer inspection on 10/22/2026.
The ICCU on the car died in the middle of the street, car would not shift out of park. Car completely died after a few minutes.
ICCU failure. I charged overnight at my home L2 charging as usual. I backed out of my garage and heard a loud pop. Almost immediately an “check electrical” warning came up. The car went to turtle mode and then completely died. The car was towed and I was informed the ICCU needed to be replaced. The car had all previous checks on ICCU performed (per mailed recalls) and was updated and passed each time.
While driving southbound on the [XXX] in a rented 2023 Kia EV6 from The Hertz Corporation, picked up in [XXX] on XXX, the vehicle entered "Power Limited" mode without warning. The vehicle lost normal propulsion and decelerated from highway speed to a crawl, forcing 4-5 emergency stops onto the highway shoulder over several miles while semi-trucks passed at 70+ mph in live traffic, with two minor children in the vehicle. The vehicle was ultimately abandoned at a highway rest stop on Hertz Roadside Assistance's instruction and towed. This vehicle was subject to three the federal safety agency recall campaigns for the ICCU defect that produces exactly this failure mode: 24V057000 (SC295, driveshaft, notice mailed XXX), 24V200000 (SC302, ICCU 12V charging failure/Power Limited mode, notice mailed XXX), and 24V867000 (SC327, expanded ICCU remedy superseding SC302, notice mailed XXX) — all mailed well before this vehicle was rented to me on XXX. Under 49 U.S.C. §30120(i), a rental company may not rent a covered rental vehicle subject to an unremedied safety recall. I am requesting the federal safety agency use its inspection authority under 49 U.S.C. §30166 to determine whether Hertz completed the required SC327 remedy on this vehicle before renting it to me, and to review Hertz's fleet-wide recall compliance for its Kia EV6 inventory. This does not appear to be an isolated incident: the federal safety agency complaint ODI XXX, filed XXX, describes a near-identical failure — a rented 2023 Kia EV6 (Dollar Rent A Car, a Hertz-owned brand) losing power and shutting down multiple times on the freeway during a single trip, also towed. Two renters, two Hertz-family rentals, same defect signature, five months apart. Hertz has been on written and verbal notice of this incident since XXX, and I sent a formal written demand on XXX with a response deadline of XXX. As of this filing, Hertz has not responded. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)
While driving a rented 2023 Kia EV6 on the freeway, the vehicle lost power and shut down completely, without warning, on multiple separate occasions during a single trip. This occurred at highway speed in live traffic, creating a serious risk to vehicle occupants and surrounding traffic. The vehicle was a rental (Dollar Rent A Car); no external damage or collision was involved. The vehicle has since been towed.
ICCU failed and replaced under warranty
First ICCU the power completely went out on 2/23/26. Power went out again April, 2026. Currently car is immobile and unreliable and not safe for driving due to power failures. Towed car to Kia Cerritos. Car supposedly "fixed" (with other issues I've reported to KIA of America & CA BAR/DMV) Currently 12V battery is not holding charge as of 4/27/26, 4/28/26, and 5/2/26. I received a letter from KIA stating ICCU and inability to charge, Keep this Letter in your Glove Box for a free diagnosis and possible no cost servicing. As an older American this is inherently unsafe, as I travel for work and cannot be stuck on the road. The vehicle suddenly loses power in traffic. It simply stops running. This is my 5th attempt to file this very complaint between April and 6/14/26.
ICCU failure, a well known issue with these cars.
Iccu failure with Kia ev6. Unreal that this car has not had a recall yet. It is totally unacceptable that this car can at any time fail. Car will not start and shut down while I was driving. Luckily I was beginning to park when it happened
