2022–2025 Mercedes-Benz S-Class: service brakes, hydraulic recall
A brake fluid leak can extend the distance needed to stop the vehicle, increasing the risk of a crash.
What was reported
Source: manufacturer filing, 49 CFR Part 573Reported to NHTSA Oct 2, 2026 by Mercedes-Benz USA, LLC.
The fix, from the dealer bulletin
Source: NHTSA remedy instructions and dealer noticeThe advisory, as filed: “Given this recall notice, it is a violation of federal law for a dealer to sell or lease any new vehicle in dealer inventory covered by this recall notification until the vehicle has been repaired.”
Read from NHTSA’s copy of the manufacturer’s dealer documents. The procedure itself is in the bulletin; a franchised dealer has the current copy on the manufacturer’s portal, and that copy governs. Working a lot or a fleet? Recall Watch carries this line on every VIN it checks: remedy status, hours, stop-sale.
Which vehicles are covered
Source: NHTSA campaign 26V638000Vehicles built from Feb 2, 2021 onward — a VIN outside that window is not part of this campaign even if the year, make and model match.

|---|---|---|---|
| 2022 Mercedes-Benz S-Class | Large Sedan | F | 10 |
| 2023 Mercedes-Benz S-Class | Large Sedan | D | 9 |

The federal paperwork

Check one specific vehicle
A recall applies to a build range, so year, make and model cannot settle it. NHTSA checks a VIN against the manufacturer's own list and tells you whether the repair is still outstanding on that vehicle.

Common questions
Source: NHTSA, 49 CFR Part 573Does this recall repair cost anything?
No. Federal law requires the manufacturer to remedy a safety defect or a compliance failure at no charge, for vehicles up to 15 years old measured from the date of first sale. A dealer that asks you to pay for a recall repair is in the wrong.
How do I know whether my vehicle is included?
By VIN, not by model year. This campaign covers vehicles built from Feb 2, 2021 onward. The manufacturer files a build range with NHTSA and only vehicles inside it are covered, so two identical-looking cars from the same year can differ. NHTSA's own lookup checks a VIN against the manufacturer's list.
What if the repair is not available yet?
It happens, and often. Manufacturers must notify owners when a defect is found even if the parts or the software are not ready, then notify them a second time once the remedy exists. The remedy filed for this campaign is described above.
What did the manufacturer say was wrong?
The problem, risk and fix quoted on this page are the manufacturer's own words as filed with NHTSA under 49 CFR Part 573. WhichTrim does not paraphrase them.
Who started this recall?
NHTSA's record credits the manufacturer. A recall can begin with the manufacturer's own testing, with a defect investigation, or with a compliance test against a Federal Motor Vehicle Safety Standard.
