If fluid escapes from a damaged front hose, it leads to a loss of hydraulic pressure in one of the circuits. While the backup circuit ensures the car can still stop, overall <strong>stopping performance will be significantly reduced<\/strong>, increasing stopping distances and raising the risk of a crash.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Affected Vehicles<\/h2>\n\n\n\n<p>This expanded action affects <strong>2022\u20132025 model year<\/strong> vehicles in the flagship S-Class (223 platform) lineup:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>2022\u20132025 Mercedes-Benz S 500 4MATIC<\/strong><\/li>\n\n\n\n<li><strong>2022\u20132025 Mercedes-Benz S 580 4MATIC<\/strong><\/li>\n\n\n\n<li><strong>2023\u20132025 Mercedes-Benz S 580 e 4MATIC<\/strong><\/li>\n\n\n\n<li><strong>2022\u20132025 Mercedes-Maybach S 580 4MATIC<\/strong><\/li>\n\n\n\n<li><strong>2022\u20132025 Mercedes-Maybach S 680 4MATIC<\/strong><\/li>\n\n\n\n<li><strong>2024\u20132025 Mercedes-AMG S 63 E Performance<\/strong><\/li>\n<\/ul>\n\n\n\n<h2 class=\"wp-block-heading\">How Did the Investigation Unfold?<\/h2>\n\n\n\n<p>This update builds upon <strong>NHTSA Campaign 25V-116<\/strong>, originally filed in February 2025.<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>The Initial Scope:<\/strong> MBAG initially attributed the brake hose failures to specific production windows and hot, humid regions where early cases were clustered.<\/li>\n\n\n\n<li><strong>New Field Data:<\/strong> Between March and August 2025, MBAG received additional field reports from outside the U.S. involving vehicles operated in different climates and built outside the original production time frame.<\/li>\n\n\n\n<li><strong>Engineering Review:<\/strong> MBAG launched a dedicated Field Engineering Activity in March 2026 to collect and analyze field components.
