Kia filed this with NHTSA as a warranty extension dated Mar 27, 2025, received May 23, 2024, about the fuel/propulsion system — 10 documents under this number: WTY034_TSB_R2, WTY034_TSB_R1, WTY034_REIMB, WTY034_OWNR_YP and 6 more. It names 9 model years (2017–2021). A warranty extension is not a safety recall — there is no NHTSA campaign number and no federal requirement — but it is usually work the manufacturer pays for on the vehicles it names; the dealer checks the VIN against the manufacturer’s list.

What the document itself lists
Labour operations and the time the manufacturer allows
| Operation | Description | Time |

Read by machine from the document NHTSA serves (5 pages), read Sep 30, 2026. A part number is shown only where it matches Kia’s own catalogue shape, an operation only with its code and time, and a description only where the reader got it whole; anything it could not settle is left out, and the PDF is the record. Times are the manufacturer’s warranty allowances, not a quote.
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 9 model years this bulletin names have filed 690 complaints with NHTSA since 2015. 331 of them name Engine, 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.
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.
While operating the vehicle, the engine suffered a catastrophic internal mechanical failure, resulting in an immediate and dangerous loss of motive power on the road. A subsequent physical diagnostic scan at an authorized Kia dealership revealed manufacturer trouble code P008800 (Fuel Rail System Pressure-Too High) along with universal…

Complete engine failure due to rods and bearings (same as all other Kia engine recalls currently active). Ironically my car wasn’t included in the recall. Also I’ve noticed that Hyundai has extended the warranty for this same engine in the 2018 Santa Fe basically acknowledging it has a problem but didn’t include the 2018 Kia cadenza…

March 2024 just before hitting 100,000 miles I started having oil consumption issues. Current milage is 137,300 About 10,000 miles ago my check engine light came on. I took it to an auto parts store and it was reading bank 1 O2 sensor. I took it for an oil change and never scheduled for the sensor replacement due to life events.

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 WTY034 a recall?
No. A warranty extension 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 WTY034 repair free?
A warranty extension 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 WTY034 cover?
The manufacturer filed it against 9 model years: 2020 Kia Cadenza, 2019 Kia Cadenza, 2018 Kia Cadenza, 2017 Kia Cadenza, 2021 Kia Sedona, 2020 Kia Sedona 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: 2019-2021MY Sedona (YP) 3.3L: built 13 Feb 2018 – 8 Jul 2020; built 2 Jun 2016 – 23 Aug 2016; built 24 Aug 2016 – 15 Oct 2020 — the build date is on the certification label in the driver’s door jamb.
