What it saysIn certain areas, a vehicleâs underbody may exhibit corrosion due to road salt usage. NHTSA’s full summary ↓
Hyundai filed this with NHTSA as a service bulletin dated Sep 20, 2023, received Oct 2, 2023, about the suspension — 2 documents under this number. It names 4 model years (2016–2019). 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 communicationWhat it applies to, as the document itself states it — the build window in the manufacturer’s own words, read by machine from the PDF NHTSA serves. The build date is on the certification label in the driver’s door jamb; the dealer settles a borderline vehicle by its VIN.
In certain areas, a vehicleâs underbody may exhibit corrosion due to road salt usage. As a preventative measure, cavity wax coating is applied to the internal surfaces of underbody components, and an undercoating spray is applied to exterior surfaces of specified underbody components. This service campaign bulletin describes the procedure to perform this preventative service on certain Santa Fe (NC) and Santa Fe XL (NC) vehicles.

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.

Common questions
Source: NHTSA, 49 CFR 579.5Is Hyundai 23-01-064H 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 23-01-064H 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 Hyundai warranty extension on file lists the ones Hyundai has filed.
Which vehicles does 23-01-064H cover?
The manufacturer filed it against 4 model years: 2019 Hyundai Santa Fe, 2018 Hyundai Santa Fe, 2017 Hyundai Santa Fe, 2016 Hyundai Santa Fe. 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: 2019MY Santa Fe XL (NC): built 18 Dec 2012 – 28 Nov 2018 — the build date is on the certification label in the driver’s door jamb.
