What owners reported
Source: NHTSA complaint databaseOwners of the 66 model years this bulletin names have filed 6,148 complaints with NHTSA since 2015. 1,662 of them name Electrical System — the same broad component group this bulletin is filed under. NHTSA groups complaints coarsely, so that means the same area of the vehicle, not necessarily the same fault.
On the 2022 Kia EV6, the 15 owners who gave an odometer reading for Electrical System reported it at a median of 16,030 miles. That figure is one model year’s, not the whole range this bulletin covers — medians from different model years are not averaged.
My 205 EV9 Wind with 24500 Miles left me stranded, the standard battery simbol that in ICE cards refers to the alternator, came on, I tried to get to the dealer about 20 miles in the way home, less that 3 miles after that the car lost power with just enough to move to the shoulder, I stopped, power the car off and tried turning it back…
2025 Kia EV9 · Electrical System · filed with NHTSA Oct 1, 2026 · ODI 11768404
Vehicle does not reliably handle the 12V battery well. Many times, I see it sitting at 12.8 VDC when driving the vehicle. On a ICE vehicle, the charging voltage is close to 14V when running/driving. On 3 separate occasions, when I tried to "start" the EV6, the 12V battery was too dead to allow the car to be started. Basically stranded.
2023 Kia EV6 · Electrical System · filed with NHTSA Apr 3, 2024 · ODI 11581040
When I started my car, during the warm-up process, it dropped revs and turned off. After several tries, it turned on. While driving, when the vehicle was stopped, it began to jerk slightly. The safety risk is that the car, while I am driving, could turn off and cause an accident, in which people could be at risk, including me.

A complaint is one owner’s account, not a defect finding, and a bulletin is not a recall. Nothing here says this bulletin was issued because of these complaints, or that the repair it describes fixed them. Complaint files on this site begin in 2015.

Common questions
Source: NHTSA, 49 CFR 579.5Is Kia TSB_ELE422 a recall?
No. A service bulletin is a manufacturer communication filed with NHTSA under 49 CFR 579.5; a safety recall carries an NHTSA campaign number (two digits, a letter, six digits) and a federal duty to repair for free. Check the vehicle’s recalls by VIN at nhtsa.gov/recalls, or on its page here.
Is the TSB_ELE422 repair free?
Not automatically. A service bulletin describes how to diagnose or repair a condition; who pays depends on the warranty in force, any extension, and the dealer. Quoting the number can save a diagnosis either way. Every Kia warranty extension on file lists the ones Kia has filed.
Which vehicles does TSB_ELE422 cover?
The manufacturer filed it against 70 model years: 2026 Kia Carnival, 2025 Kia Carnival, 2024 Kia Carnival, 2023 Kia Carnival, 2022 Kia Carnival, 2026 Kia EV6 and more. Whether one particular vehicle is affected is a matter of its VIN and its build, not its model year alone.
