Kia filed this with NHTSA as a manufacturer communication dated Sep 1, 2026, received Aug 29, 2026, about the electrical system — 6 documents under this number: PI2601B_OWNR, PI2601B_OM_Leaf, PI2601B_TSB, PI2601B_QA and 2 more. It names 3 model years (2024–2026).

Quoting the number at a service desk can save a diagnosis.

Read by machine from the document NHTSA serves (14 pages), read Sep 30, 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 3 model years this bulletin names have filed 261 complaints with NHTSA since 2015. 122 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.
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…

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 PI2601B 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 PI2601B 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 PI2601B cover?
The manufacturer filed it against 3 model years: 2026 Kia EV9, 2025 Kia EV9, 2024 Kia EV9. 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: EV9 (MV1, MV1 GT): built 25 Sep 2023 – 15 Oct 2024; EV9 (MV1A): built 17 May 2024 – 16 Jul 2026 — the build date is on the certification label in the driver’s door jamb.
