Read by machine from the document NHTSA serves (8 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. Listings and prices on eBay Motors are the seller’s.
Affiliate disclosure: some links on this page are affiliate links. If you request a quote or buy through them we may earn a commission at no extra cost to you. Nothing on this page changes because of it.
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 1,908 complaints with NHTSA since 2015. 148 of them name Power Train — 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 2020 Kia Telluride, the 13 owners who gave an odometer reading for Power Train reported it at a median of 9,500 miles. That figure is one model year’s, not the whole range this bulletin covers — medians from different model years are not averaged.
My new AWD 2022 Kia Telluride vibration/ humming at 65 mph and above from day 1. It’s been in service 5 times and they are not able to fix the problem. The dealership we bought it from didn’t even admit there is a problem so we had to take it to another dealership which actually admitted there is a problem.

Shortly after purchasing this AWD vehicle, there is a distinct vibration at highway speeds. The vibration starts at 67 MPH and is there until speeds exceed 75 MPH, where things start to smooth out once again. There is also an odd noise inside the vehicle while the vehicle is traveling in this speed range.

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 SC303Z 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 SC303Z 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 SC303Z cover?
The manufacturer filed it against 5 model years: 2024 Kia Telluride, 2023 Kia Telluride, 2022 Kia Telluride, 2021 Kia Telluride, 2020 Kia Telluride. 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: 2020-2024MY Telluride (ON): built 9 Jan 2019 – 19 Oct 2023; Telluride (ON): built 9 Jan 2019 – 19 Oct 2023 — the build date is on the certification label in the driver’s door jamb.
