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.

2020 Kia Soul · Structure · filed with NHTSA Nov 11, 2019 · ODI 11279413
I had driven the car for about 80 miles on a mix of urban expressway, parkway, and city streets, when inexplicably the "frunk lid" (or hood) released itself from the fully closed position to the "ajar" position. That is the position that the lid would assume if you pulled the inside release.

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 TSB_BOD336 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 TSB_BOD336 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 TSB_BOD336 cover?
The manufacturer filed it against 15 model years: 2024 Kia EV6, 2023 Kia EV6, 2022 Kia EV6, 2024 Kia EV9, 2020 Kia Optima, 2019 Kia Optima and more. 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: EV6 (CV): built 20 Dec 2021 – 16 May 2024; Optima Hybrid (JFE): built 21 Feb 2019 – 25 Sep 2019; EV9 (MV1): built 25 Oct 2023 – 20 Mar 2024 — the build date is on the certification label in the driver’s door jamb.
