Mercedes-Benz has issued a safety recall for 30,078 vehicles in the United States. The recall targets select high-end Maybach sedans, AMG performance models, and S-Class vehicles due to a dangerous front-axle brake hose issue. Filed with the National Highway Traffic Safety Administration (NHTSA), the campaign expands an earlier 2025 safety action. Further testing revealed that accumulated thermal and mechanical stress could cause premature material fatigue and brake fluid leaks.
Affected Mercedes-Benz, Maybach, and AMG Models
The recall affects specific luxury models produced between February 2, 2021, and November 28, 2024. According to NHTSA documentation and manufacturer filings under campaign number 26V638000, the affected vehicles include:
- 2022-2025 Mercedes-Maybach S 580 4MATIC (947 units)
- 2022-2025 Mercedes-Maybach S 680 4MATIC (1,070 units)
- 2023-2025 Mercedes-AMG S 63 E Performance (1,760 units)
- 2022-2025 Mercedes-Benz S 500 4MATIC (7,143 units)
- 2022-2025 Mercedes-Benz S 580 4MATIC (16,881 units)
- 2023-2025 Mercedes-Benz S 580 e 4MATIC (2,277 units)
The Defect: Risk of Brake Fluid Leaks and Reduced Stopping Power
The core of the issue stems from front-axle brake hoses that may fail to meet long-term durability specifications. Over the vehicle’s operating lifespan, continuous thermal and mechanical stress can lead to accumulated material fatigue. This can cause the hoses to rupture or leak brake fluid.
The S-Class braking system relies on dual hydraulic circuits. A compromised hose can drain one circuit and diminish braking efficiency. Mercedes-Benz warns that drivers will not receive advanced warning before a leak begins. Once a fluid drop occurs, motorists will typically see a red brake fluid warning message displayed in the vehicle’s instrument cluster.
Expansion of an Earlier 2025 Safety Campaign
This latest action builds upon an initial recall, Recall No. 25V116, launched in February 2025. That recall covered roughly 20,339 cars. Initially, Mercedes-Benz AG attributed the hose failures to specific hot and humid climates and restricted production windows.
However, subsequent field reports from international markets operating in varied climate zones prompted a deeper investigation. Mercedes collected suspect parts and partnered with supplier Continental Automotive Technologies for laboratory and durability testing. Review of these test results in July 2026 led the automaker to widen the recall scope. It now includes all vehicles manufactured prior to the introduction of a modified, more durable brake hose design.
Manufacturer records indicate three U.S. field reports connected to the expanded population. However, Mercedes-Benz USA has received no reports of accidents, injuries, or property damage resulting from the defect.
Next Steps and Owner Notification
Authorized Mercedes-Benz dealerships will replace both front-axle brake hoses free of charge. Owners wishing to verify if their specific vehicle is included can check their Vehicle Identification Number (VIN) on the official NHTSA website.
Mercedes-Benz has already alerted dealerships regarding the action. Official notification letters are scheduled to be mailed to registered vehicle owners via first-class mail starting November 27, 2026. For further assistance, owners can reach out to Mercedes-Benz USA customer service directly.
