Mercedes-Benz is recalling 30,064 vehicles because their front brake hoses may rupture and leak brake fluid, reducing braking performance.
Mercedes-Benz USA, LLC (MBUSA) is recalling certain 2022-2025 S 500 4MATIC, Maybach S 580 4MATIC, Maybach S 680 4MATIC, S 580 4MATIC, 2023-2025 S 580 E 4MATIC, and 2024-2025 AMG S 63 E Performance vehicles. The front brake hoses may rupture and leak brake fluid.
Affected VINs should be searchable now at the NHTSA website.
Here is the relevant information from the NHTSA recall notice and Mercedes-Benz recall report:
NHTSA ID Number: 26V638
Manufacturer: Mercedes-Benz USA, LLC
Components: SERVICE BRAKES, HYDRAULIC
Potential Number of Units Affected: 30,064
Estimated percentage with defect: 100%
Descriptive Information
Model Year 22-25 Maybach S 580 4MATIC 947 vehicles
Model Year 22-25 Maybach S 680 4MATIC 1,070 vehicles
Model Year 24-25 AMG S 63 E PERFORMANCE: 1,746 vehicles
Model Year 22-25 S 500 4MATIC 7,143 vehicles
Model Year 22-25 S 580 4MATIC 16,881 vehicles
Model Year 23-25 S 580 e 4MATIC 2,277 vehicles
The recall population was determined through production records.
The vehicles outside this recall population have brake hoses that meet production durability specifications.
Description of defect or noncompliance:
Mercedes-Benz AG (“MBAG”), the manufacturer of Mercedes-Benz vehicles, has determined that on certain Model Year (“MY”) 2022 – 2025 S-Class (223 platform) vehicles, the brake hoses on the front axle might develop a leak over the vehicle’s lifetime.
Description of the safety risk, including crash, fire, death, injury:
If brake fluid leaks from the brake hose, it might lead to a reduced braking performance in one of the two brake circuits, increasing the risk of a crash.
Description of the cause:
Affected brake hoses might not meet durability specifications as a result of accumulated material fatigue due to increased thermal and mechanical stresses sustained over the vehicle’s lifetime.
Identification of any warning that can occur:
Before the issue occurs, the driver will not receive a warning due to the nature of the failure mechanism.
When the issue occurs, the driver might notice a red brake fluid warning message in the instrument cluster.
Chronology
This recall expands upon the vehicle population subject to Recall No. 25V116, filed on February 24, 2025. Please refer to the Chronology submitted with that recall report. Based on the field information and technical evidence then available, MBAG had identified two factors associated with the condition: climatic exposure and a particular vehicle production period. The available field data indicated that the reported cases were concentrated in particular climatic regions and within that production period. MBAG therefore defined the original recall population using those factors.
Following the decision to conduct a recall, MBAG continued monitoring field performance of the front brake hoses, including vehicles both within and outside the original recall population. Between March and August 2025, MBAG received additional field reports from markets outside the United States involving vehicles produced outside the original recall production range and, in some instances, operated outside the climatic regions on which the original population determination had been based. These reports presented information that was not reflected in the data available when the original recall population was determined and prompted MBAG to reassess whether the condition might extend beyond the originally identified production period and climatic regions.
During September and October 2025, MBAG reviewed the additional reports and available vehicle and production information to determine the appropriate means of obtaining and analyzing representative field parts. In November 2025, MBAG began coordinating a dedicated Field Engineering Activity to obtain additional brake hoses from vehicles exhibiting the reported condition. From November 2025 through February 2026, MBAG identified candidate vehicles and markets, developed the collection protocol, and coordinated the retrieval and shipment of the requested components. The Field Engineering Activity was formally launched in March 2026.
By June 2026, the requested brake hose components had been collected and returned to MBAG. MBAG forwarded the components to the supplier for detailed technical analysis and testing.
In July 2026, MBAG reviewed and discussed the results of the supplier’s laboratory and durability testing for the retrieved field parts. Based on the additional field reports, the analysis of the retrieved components, and the resulting laboratory and durability testing, MBAG reassessed the affected vehicle population with respect to production range and climatic restrictions. As a result, MBAG identified an expanded vehicle scope covering vehicles produced up to the implementation of a modified brake hose design in series production. MBAG subsequently identified the potentially affected vehicles in the field. On September 25, 2026, MBAG determined that a potential safety risk cannot be ruled out for the expanded vehicle population and decided to expand the recall.
In the United States, MBAG is aware of three reports involving vehicles in the expanded recall population, dated 04/02/2026, 05/29/2026 and 08/10/2026. MBAG is not aware of any cases of crashes, injuries, or property damage related to this condition in the expanded recall population.
Remedy
Description of Remedy
