Stopping distances can stretch on 30,064 Mercedes S-Class and Maybach sedans with rupturing brake hoses

Mercedes-Benz USA has widened a brake recall to 30,064 of its most expensive sedans after finding that front brake hoses on cars outside its original recall were also wearing out. The expansion reaches 2022 through 2025 S-Class models, the Maybach S 580 and S 680, the S 580 e and the AMG S 63 E Performance.

The failure is a slow one. A brake hose ages through years of heat and flexing, then gives way, and the first sign a driver gets may be the car itself needing more road to stop.

Fatigued hoses on the front axle

NHTSA records the action as campaign 26V638000, received October 2, 2026. Mercedes-Benz USA states the defect in a single sentence: the front brake hoses may rupture and leak brake fluid. The consequence field adds that a leak can extend the distance needed to stop the vehicle, increasing the risk of a crash.

The company’s detailed defect report explains why. The hoses may fall short of durability specifications because of material fatigue from thermal and mechanical stress over the life of the vehicle. Fluid loss then reduces braking in one of the two brake circuits. The report lists no warning before a hose lets go, because of how the fatigue develops. Afterward, the driver might see a red brake fluid warning message in the instrument cluster.

Mercedes-Benz USA is aware of three U.S. reports involving vehicles in the expanded group, dated April 2, May 29 and August 10, 2026, and it knows of no crashes, injuries or property damage tied to the condition. Three reports against 30,064 cars is a thin record, and the company is not recalling on the strength of crashes. It is recalling on the strength of a failure mode that its own durability testing shows can occur on any hose built before the redesign, which is a prediction about the fleet and not a count of incidents.

The platform matters too. The defect report ties the problem to the S-Class built on the 223 platform and lists six models in all: the S 680, S 500, S 580 e, AMG S 63 E Performance, Maybach S 580 and S 580. NHTSA breaks those into 21 model-and-year entries across 2022 through 2025, with the plug-in S 580 e starting in 2023 and the AMG S 63 E Performance in 2024, so a VIN check is the only reliable way for an owner to know whether a particular car is covered.

Why a second recall followed the first

This campaign grows an earlier one. Recall 25V116 was reported on February 24, 2025 and covered about 20,339 cars from the 2021 through 2023 model years, with owner letters dated April 25, 2025 and the same remedy of new front brake hoses. That first population was drawn by climate and by a particular production period, on the theory that heat and the build window explained which hoses would fail.

The theory did not hold. Field reports from outside the United States involved cars built outside that production range, and some of them in other climates. Field-part analysis and durability testing in July 2026 led the company to broaden the population to every vehicle built before an optimized hose entered production, a window running from February 2, 2021 through November 28, 2024. On September 25, 2026, Mercedes decided the risk could not be ruled out for that larger group and filed the expansion.

Press coverage of the filing, including a syndicated Fox station report, notes that the carmaker used data from markets outside the United States to justify widening the recall and reports the new campaign as expanding last year’s. The sequence shows how a recall boundary is drawn on the evidence available at the time: the first one was written on a climate and production pattern that later reports showed to be too narrow.

What braking standards say about a leaking hose

Federal brake rules anticipate partial hydraulic failure. Under the federal brake standard, FMVSS No. 135, a car with a split brake system must show that the remaining circuit can still stop it after a single rupture or leak, and from 100 kilometers per hour the stop must come within 168 meters. The same standard requires a warning indicator that lights on a gross loss of fluid or pressure. A hose failure of the kind described is the scenario those rules were written around, and it fits the filing’s wording about longer stopping distances rather than a total loss of braking.

Longer is still the operative word. A stop that takes extra distance at highway speed is the margin between a close call and a rear-end collision, and the driver gets no advance notice that the margin has shrunk. The filing lists no interim instruction for owners and no notice to park the cars, so the vehicles remain on the road until the new hoses are fitted.

Dealer fix and the owner schedule

The remedy is straightforward: an authorized dealer replaces the front-axle brake hoses at no charge. The company states that the optimized hose used in production prevents the problem on cars built from November 29, 2024 onward. Dealers were notified October 9, 2026, the same day VINs became searchable, and owner letters are expected November 27, 2026 in a phased mailing. Owners can check a VIN at NHTSA’s recall lookup or call Mercedes-Benz USA at 1-800-367-6372. Anyone whose car was fitted with new hoses under 25V116 should still ask a dealer whether it falls in the expanded population.
