Kia filed this with NHTSA as a service bulletin dated Aug 19, 2025, received Aug 20, 2025, about the electrical system — 1 document under this number: TSB_ELE393. It names 1 model year (2025). A service bulletin is not a safety recall: it is the manufacturer telling its dealers how to diagnose or repair a condition, and whether the work is paid for depends on the warranty in force. Quoting the number at a service desk can save a diagnosis.

What the bulletin says

TECHNICAL SERVICE BULLETIN: SERVICE ACTION: FRONT MOTOR AND REDUCTION GEAR (GDU) ASSEMBLY REPLACEMENT (SA622) - This bulletin provides information to replace the Front Motor Reduction Gear Assembly (GDU) on certain 2025MY EV9 (MV1a) vehicles produced from November 25, 2024 through December 06, 2025 that were assembled at the Kia assembly plant in the US. The affected vehicles may experience abnormal noise coming from the front GDU which is caused by a missing wave washer from the motor inside the front GDU.

Read by machine from the document NHTSA serves (4 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.

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 21 complaints with NHTSA since 2015. 7 of them name Electrical System, Power Train — 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…

Common questions
Source: NHTSA, 49 CFR 579.5Is Kia SA622 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 SA622 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 SA622 cover?
The manufacturer filed it against 1 model year: 2025 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: 2025MY EV9 (MV1a): built on or after 25 Nov 2024; EV9 (MV1a): built 25 Nov 2024 – 6 Dec 2025 — the build date is on the certification label in the driver’s door jamb.
