What the bulletin says
Source: NHTSA's summary of the manufacturer's communicationCertain 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.

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.

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.
