Kia bulletin SA658
Kia filed this with NHTSA as a service bulletin dated Aug 21, 2026, received Sep 2, 2026, about the electrical system — 1 document under this number: TSB_ELE434. It names 1 model year (2027). 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
Source: NHTSA's summary of the manufacturer's communicationTECHNICAL SERVICE BULLETIN: SERVICE ACTION: SBCM SOFTWARE LOGIC IMPROVEMENT (SA658) - This bulletin provides information to upgrade the Side Body Zone Control Module - Driver ‘SBCM_DRV’ and Side Body Zone Control Module - Assist ‘SBCM_AST’ systems software on certain 2027MY Telluride (LQ2a) and 2027MY Telluride Hybrid (LQ2a HEV) vehicles produced from March 13, 2025 through August 27, 2025. Some of the affected vehicles may exhibit a popping noise from one or both outside sideview mirror(s) after the auto fold/unfold function is enabled and the vehicle is locked. This condition is caused by the SBCM sending an additional fold command after the mirrors have already completed the folding operation. This condition does not affect the ability of the mirror to fold or unfold.

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.

Common questions
Source: NHTSA, 49 CFR 579.5Is Kia SA658 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 SA658 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.
Which vehicles does SA658 cover?
The manufacturer filed it against 1 model year: 2027 Kia Telluride. Whether one particular vehicle is affected is a matter of its VIN and its build, not its model year alone.
