Quoting the number at a service desk can save a diagnosis.

Read by machine from the document NHTSA serves (7 pages), read Sep 30, 2026. A part number is shown only where it matches Hyundai’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 13 model years this bulletin names have filed 1,086 complaints with NHTSA since 2015. 110 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 Hyundai Elantra, the 24 owners who gave an odometer reading for Power Train reported it at a median of 5,000 miles. That figure is one model year’s, not the whole range this bulletin covers — medians from different model years are not averaged.
I started noticing what I refer to as a "lurch" when driving. It happened a few times when I was driving around 35mph, so I thought I was imagining it. Then when I was driving on the highway on 4/14, I felt like I could not accelerate. When I looked at the tachometer, it was jumping between 2 to 3, and as it jumped, the car lurched.

Complete and sudden clutch failure and unable to shift into any gear. No clutch slippage or change in engage point/clutch burning smell. Was traveling at relatively low speed (35mph). Dealership tried to get me to tell my insurance company it was due to water damage and then quoted me almost $7,000 to replace the clutch

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 Hyundai 23-AT-010H 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 23-AT-010H 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 23-AT-010H cover?
The manufacturer filed it against 13 model years: 2022 Hyundai Accent, 2021 Hyundai Accent, 2020 Hyundai Accent, 2023 Hyundai Elantra, 2022 Hyundai Elantra, 2021 Hyundai Elantra and more. Whether one particular vehicle is affected is a matter of its VIN and its build, not its model year alone.
