Kia EV6 stalling problems

Filed Nov 3, 2026 · Electrical · WA · fire

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.

Dear Kia Customer Care, I am writing to formally report a serious and recurring safety issue with my Kia vehicle. I have repeatedly experienced a "Power Limited" error while driving, often accompanied by a turtle icon and a "Check Electric Vehicle System" warning. On multiple occasions, the vehicle has suddenly lost power and stalled in the middle of the road. This is extremely dangerous and has put me and other drivers at risk. A vehicle should never lose propulsion unexpectedly, especially in active traffic conditions. I request an immediate investigation into this issue, along with a clear explanation of the cause and a permanent fix. Please treat this matter with urgency, as it directly concerns driver safety. Kindly confirm the next steps and the earliest available service appointment. Thank you,

The 12-volt battery has failed twice and was ultimately replaced. Additionally, the ICCU unit was replaced once. The vehicle has now returned to the shop for the same recurring issue, as the 12-volt battery either fails to hold a charge or is not charging properly. Most concerning, the vehicle stalled while in motion, creating a serious safety hazard, as it was not possible to activate the hazard lights, leaving occupants in a potentially dangerous situation.

While driving my car a warning flashed stating "check electrical vehicle system." Pulled over, contacted Kia of Abilene and asked if we could drive the car to the dealership. While on the phone another warning flashed ""Stop vehicle and check power supply." Attempted to drive car, "Limp mode or turtle mode" occurred and the max speed for the car was 25mph, sudden loss of acceleration. Made it home, which was approximately 2 miles away, and it seems like the 12V battery was draining quickly. Eventually the vehicle stalled at home and became unresponsive, no power. Contacted roadside assistance and the vehicle was towed to Kia of Abilene. All of this occurred March 29th at approximately noon. The dealership finally contacted us today, April 2nd, and notified us it was an ICCU failure and the part wasn't available with no foreseeable time-frame for repair. The car is absolutely inoperable!

While driving with the hatch open, while carrying objects to long to place in car, (The drive was less than one mile and yes I had a red flag on my kayaks) I was driving in what is called 1Pedal driving. When coming to a stop light unbeknownst to me the emergency brakes (Parking brake) automatically comes on. I was unable to continue in drive until manually unlocking parking brake, but it took me a minute to figure out what was the issue. During this time I was blocking traffic till I figured the work around. This undoubtedly a software glitch by kia's programmers. To ensure that this was not a singular incident, I took the car on a quiet street to replicate this by keeping the hatch slightly ajar while coming to a standard stop like a stop sign as if I had stopped in traffic as well as stopping as if I was in traffic.. I attempted this over a dozen times. Each time in the 1Pedal mode the emergency brakes came on and wouldn't disengage till manually doing so. I have not tried to replicate this other regenerative braking modes other than 1Pedal. But when I get back to an area where traffic is not an issue I will see if it is an issue with those modes as well. I notified the service department of this matter when I Brought in the car in for software update for a safety recall. The service department did not do anything to see if there was a fix other than take a written statement that I left with them. This becomes a safety issue for the following reasons. 1. First, there is no mentioned in the Kia EV6 bible on this issue and this will take place, so there is no warning to the driver that this going to happen. 2. When coming to a stop and car does not move a nervous or inexperience driver may panic or not no what to do to remedy the situation, thinking the car is dead. And thus leaving a car obstructing the flow of regular as well emergency vehicular. 3. Driver behind the stalled vehicle may plow into the rear end of the stalled vehicle.

There is a structural issue where the hinges from the tailgate attaches to the body. I believe my tailgate alignment issue happened during assembly and has happened to others. More important if the tailgate is opened when car is not completely level when try to close the tailgate shifts and reopens since it cannot close as designed. I have informed Kia America in Irvine, Ca with a letter to the CEO over 3 weeks ago but no response. I followed up with a certified letter that was received by them but again no response. This is a safety structural problem that needs to be investigated. I have also contacted Kia consumer affairs and keep getting stalled. I have trouble loading the videos but have photos, the red car is mine, the others are also attached.
