2023 MERCEDES-BENZ Eqs 450+

The vehicle has experienced recurring intermittent failures of Active Brake Assist and Active Blind Spot Assist. The systems may function normally and then unexpectedly become unavailable, with warning messages appearing in the vehicle. The primary driver was nearly involved in an accident during one occurrence when Active Brake Assist unexpectedly became unavailable. No collision occurred, but the loss of the braking-assistance function created a serious safety concern. The problem has been inspected by authorized Mercedes-Benz dealers on multiple occasions. During an April 2026 dealer visit, the dealer documented both the Blind Spot and Active Brake Assist warnings, stored communication fault codes involving the front radar sensor/DISTRONIC, a bent front radar sensor bracket, and a loose front grille. The problem later recurred, and the vehicle was returned to a Mercedes-Benz dealer on August 27, 2026. The vehicle remains at the dealership and is available for inspection. The dealer now states that the front radar/module mounting bracket is cracked and attributes the condition to outside impact. The vehicle has never been in an accident and there is no visible damage to the front emblem or exterior front of the vehicle. When asked how the dealer determined that an impact caused the bracket damage, the owner was told that the DTC report supported that conclusion, but the dealer declined to provide a copy of the report. During the same discussion, a Mercedes-Benz service consultant stated that the bracket is very flimsy and can crack from something as minor as leaning on the vehicle. This raises concern that the mounting bracket for a safety-related radar system may be unusually susceptible to damage during ordinary use. The recurring failures affect systems related to collision warning, automatic braking assistance, and blind spot detection. The vehicle and affected components remain with the Mercedes-Benz dealer and should be available for inspection.
