I experienced a serious incident involving the Hands-Free Access function in my 2025 Mercedes-Benz GLC 350e. While unloading a rollable walker from the trunk, the trunk door unintentionally closed, striking me hard on the head. I have a mobility issue and use a rollable walker every day. This requires me to load and unload the walker into and from the trunk multiple times a day. The impact of the trunk door caused me to lose my balance, resulting in a fall onto a concrete surface. This fall caused me to hit my head again on the ground, exacerbating the injury. The unintentional operation of the trunk created a hazardous situation, especially given my physical limitations and frequent need to access the trunk. This unintentional closing of the trunk door has happened several times, creating an ongoing safety concern. I attempted to locate detailed information about the Hands-Free Access function in both the printed and online operator's manuals for the 2025 GLC 350e, but I could not find a description of this feature. This lack of documentation raises further safety concerns, as it prevents users from understanding the proper use, potential risks, or deactivation options for the feature. The incident caused a head injury and a subsequent fall, leading to a secondary head impact on the concrete. I am deeply concerned about the potential for similar accidents involving other users. I urge the NHTSA to investigate the Hands-Free Access feature on the 2025 Mercedes-Benz GLC 35
