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.
Certain Santa Fe (MX5A) and Santa Fe Hybrid (MX5A HEV) vehicles may produce a “pop”, “tick”, or “creak” noise from a missing weld on the mounting stud of the right front subframe while driving. The vehicle’s structural integrity is maintained even with a missing weld; however, drivers may report an abnormal noise coming from the affected area during certain driving scenarios. This bulletin describes the procedure to inspect, and if necessary, repair the missing weld on the mounting stud to eliminate the noise.

Common questions
Source: NHTSA, 49 CFR 579.5Is Hyundai 9C4 a recall?
No. A service campaign 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 9C4 repair free?
A service campaign 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 9C4 cover?
The manufacturer filed it against 1 model year: 2025 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: built 4 May 2025 – 15 May 2025; built 2 May 2025 – 14 May 2025 — the build date is on the certification label in the driver’s door jamb.
