Brake pads completely worn after 11K miles - this seems like premature wear and like there is a potential issue with the braking system on the GLS450.

I am writing to file a formal complaint regarding a serious malfunction of the Automatic Emergency Braking (AEB) system. This malfunction caused my vehicle to unexpectedly perform an emergency stop without a valid cause, resulting in significant damage to its suspension system. Incident Details: •Date of Incident: Friday, December 5, 2025, between 10:45 am and 11:15 am ET •Location: Community Baptist Church of Englewood, 224 1St, Englewood, New Jersey. •Description: While driving under normal conditions on a clear, dry road with no obstructions, the vehicle's AEB system engaged suddenly and forcefully. The abrupt, maximum-force braking caused severe stress and impact on the vehicle's suspension components, leading to a bent suspension linkage/component. The car is currently unsafe to drive. The damage to the suspension was not a result of normal wear and tear or an external impact caused by a collision. It was a direct consequence of a failure within a critical safety system designed and installed by Mercedes-Benz. An abrupt emergency stop due to a system malfunction places extreme, unintended stress on the vehicle's mechanical components, including the suspension and alignment systems. While Mercedes-Benz of Smithtown Service authorized the repair and will fully cover its cost, the reason was noted for to agreement was noted as “not to argue with a client who has a long-standing relationship with Mercedes-Benz.” I am asking for this to be officially reported as a defect for Mercedes-Benz to resolve in their design, which will safeguard all future and current drivers as well as the public.
