What the bulletin says
Source: NHTSA's summary of the manufacturer's communicationWhat it applies to, as the document itself states it — the build window in the manufacturer’s own words, read by machine from the PDF NHTSA serves. The build date is on the certification label in the driver’s door jamb; the dealer settles a borderline vehicle by its VIN.
TECHNICAL SERVICE BULLETIN: VOLUNTARY EMISSIONS SERVICE CAMPAIGN: This bulletin provides information to upgrade the 12-volt battery (“12V battery”) diagnostic software for certain 2025MY EV6 (CVa) vehicles produced from December 17, 2024 through November 5, 2025. The subject vehicles are equipped with a 12V battery which requires periodic inspection and maintenance. To provide enhanced monitoring of the 12V battery’s performance, the software upgrade will periodically conduct 12V battery performance tests and provide drivers with advance notice of sub-optimal 12V battery performance.

Read by machine from the document NHTSA serves (6 pages), read Oct 14, 2026. A part number is shown only where it matches Kia’s own catalogue shape, an operation only with its code and time, and a description only where the reader got it whole; anything it could not settle is left out, and the PDF is the record. Times are the manufacturer’s warranty allowances, not a quote. Listings and prices on eBay Motors are the seller’s.
Affiliate disclosure: some links on this page are affiliate links. If you request a quote or buy through them we may earn a commission at no extra cost to you. Nothing on this page changes because of it.
The summary is NHTSA’s abstract of the document, as filed under 49 CFR 579.5. One communication is usually filed as several documents — the bulletin, a dealer notice, an owner letter — and the number on any of them finds this page. A PDF link is shown only once NHTSA’s own server has been seen to serve that document; the rest are checked over the following nights. Quote the number at a service desk; it is what the dealer’s system is keyed on.

What owners reported
Source: NHTSA complaint databaseOwners of the 1 model year this bulletin names have filed 55 complaints with NHTSA since 2015. 40 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.
When shifting from reverse to drive there was a loud pop towards the back up the car. A check electrical system warning popped up, and then eventually a Check Power Supply stop now warning came up. The vehicle would not go above 26MPH and had to be stopped in a parking lot to be towed to the dealership.

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 PI2606 a recall?
No. A manufacturer communication 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 PI2606 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 PI2606 cover?
The manufacturer filed it against 1 model year: 2025 Kia EV6. Whether one particular vehicle is affected is a matter of its VIN and its build, not its model year alone. The document itself sets the build window: 2025MY EV6 (CVa): built 17 Dec 2024 – 5 Nov 2025; EV6 (CVa): built 17 Dec 2024 – 5 Nov 2025 — the build date is on the certification label in the driver’s door jamb.
