Kia filed this with NHTSA as a service bulletin dated Sep 26, 2024, about the electrical system. It names 2 model years (2023–2024). 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.

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.

What owners reported

Source: NHTSA complaint database

Owners of the 2 model years this bulletin names have filed 84 complaints with NHTSA since 2015. 29 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.

The 12-volt battery system in my 2024 Kia Niro (VIN: ) has suffered two total failures in under one year of ownership (approx. 10,000 miles). In both instances, the vehicle was completely unresponsive, with no power to essential systems. Safety Risks and Incidents: 1. : Vehicle experienced a total power loss.

Common questions

Source: NHTSA, 49 CFR 579.5

Is Kia PS771 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 PS771 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 PS771 cover?

The manufacturer filed it against 2 model years: 2024 Kia Niro, 2023 Kia Niro. Whether one particular vehicle is affected is a matter of its VIN and its build, not its model year alone.
