Kia filed this with NHTSA as a service bulletin dated Jun 27, 2023, received Jul 5, 2023, about the fuel/propulsion system. It names 2 model years (2018–2019). 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 communicationPicked out of NHTSA’s summary below, word for word. The document itself is the record, and the dealer checks the VIN.
WARRANTY EXTENSION: DEALER PRINCIPAL MEMO - This document is the announcement to the dealer principals that Kia is extending the New Vehicle Limited Warranty coverage, to all owners, for the low-pressure fuel pump on 2018-2019 MY Sorento vehicles from 5 years / 60,000 miles to 15 years / unlimited miles, whichever comes first, starting from the date the vehicle was first put into service. The low-pressure fuel pump in the subject vehicles may develop a fuel leak over time and after prolonged exposure to extreme high temperatures due to insufficient thickness of the fuel pump port.

What owners reported
Source: NHTSA complaint databaseOwners of the 2 model years this bulletin names have filed 682 complaints with NHTSA since 2015. 42 of them name Fuel/Propulsion 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.
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 WTY033_DPSM 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 WTY033_DPSM 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 WTY033_DPSM cover?
The manufacturer filed it against 2 model years: 2019 Kia Sorento, 2018 Kia Sorento. Whether one particular vehicle is affected is a matter of its VIN and its build, not its model year alone.
