What owners reported
Source: NHTSA complaint databaseOwners of the 1 model year this bulletin names have filed 167 complaints with NHTSA since 2015. 49 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.
While driving my 2023 Sorento plug-in hybrid a msg appeared that Charging Stopped Check Cable. When you stop the car and try to drive it will not go into any gear, msg says Shifting Conditions Not Met and Unplug Vehicle to Start and the wheels are locked up (E-brake) and needs a tow truck with dollies in order to load.

Common questions
Source: NHTSA, 49 CFR 579.5Is Kia SA573 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 SA573 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 SA573 cover?
The manufacturer filed it against 1 model year: 2023 Kia Sorento. 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: 2023MY Sorento PHEV (MQ4 PHEV): built 27 Jun 2022 – 16 Aug 2023; Sorento PHEV (MQ4 PHEV): built 27 Jun 2022 – 16 Aug 2023 — the build date is on the certification label in the driver’s door jamb.
