Mercedes-Benz Recalls Over 30,000 S-Class Sedans

Mercedes-Benz has expanded its S-Class safety recall to over 30,000 vehicles (NHTSA No. 26V638) due to faulty front brake hoses. The expanded campaign now covers 2022–2025 models, including Maybach and AMG variants, to address potential fluid leaks caused by material fatigue.

The recall expansion was initiated following the receipt of international field reports, which prompted Mercedes-Benz to evaluate whether the defect was isolated to specific regions or manufacturing timelines. Following extensive inspections and laboratory testing, the manufacturer opted to broaden the scope of the campaign. By September, Mercedes-Benz determined that a potential safety risk could not be ruled out for this expanded population of vehicles.

The recall now extends to 2022–2025 S-Class models, including the Mercedes-Maybach and Mercedes-AMG variants. Vehicles manufactured between February 2, 2021, and November 28, 2024, may be subject to this campaign.

Here is the breakdown of the 30,078 potentially affected vehicles in the US:

The issue stems from the front brake hoses, which are susceptible to leaks due to material fatigue caused by prolonged exposure to heat and stress. Should brake fluid escape, the vehicle may experience a loss of braking power in one of its two circuits, significantly compromising safety.

In the event of a failure, a red brake fluid warning light will illuminate on the dashboard; however, motorists should be aware that there is no advance warning prior to the onset of this mechanical issue.

Mercedes-Benz initiated an expansion of the recall following an influx of field reports received between March and August 2025. This decision followed a comprehensive investigation, which included the laboratory analysis of brake hoses and an extensive review of durability testing results conducted in July 2026 to assess potential vehicle risk.

The manufacturer has acknowledged three incidents reported this year involving vehicles within the expanded U.S. recall population, specifically occurring on April 2, May 29, and August 10. To date, the company has reported no crashes, injuries, or property damage associated with this group of vehicles.

Mercedes-Benz will replace front brake hoses on affected models to resolve leak risks. Newer units built after November 29, 2024, are unaffected. Owners will receive notifications starting November 27; please check your VIN on the NHTSA website or contact your dealer to verify eligibility. Owners are advised to schedule repairs immediately and, as a precaution, avoid driving the vehicle and park it outdoors until serviced.
