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 5 model years this bulletin names have filed 641 complaints with NHTSA since 2015. 358 of them name Engine, 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.
On the 2019 Kia Sorento, the 48 owners who gave an odometer reading for Engine reported it at a median of 83,537 miles. That figure is one model year’s, not the whole range this bulletin covers — medians from different model years are not averaged.
The contact owns a 2020 Kia Sedona. The contact stated that while driving at an undisclosed speed, the vehicle lost motive power with several unknown warning lights illuminated. The vehicle was towed to the dealer, where the vehicle was diagnosed with battery failure. The contact was informed that the battery needed to be replaced.

Common questions
Source: NHTSA, 49 CFR 579.5Is Kia SC365 a recall?
No. A emissions 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 SC365 repair free?
A emissions communication is usually paid by the manufacturer on the vehicles it names, within the terms and time limit the document sets; the dealer checks the VIN against the manufacturer’s list.
Which vehicles does SC365 cover?
The manufacturer filed it against 5 model years: 2021 Kia Sedona, 2020 Kia Sedona, 2019 Kia Sedona, 2020 Kia Sorento, 2019 Kia Sorento. Whether one particular vehicle is affected is a matter of its VIN and its build, not its model year alone.
