NHTSA complaint #11755626, filed 2026-08“So this is an Amazon delivery vehicle. The driver stuck his head out the drivers side window to get a better view when backing up, as his head was out the window he hit the window switch and instead of the window going down, it malfunctioned and went up instead, catching his neck and his entire head was stuck. Concerned citizens even tried getting inside the van and helping but when they tried to press the window button DOWN, it would only go up. (The wrong way) this resulted in almost having to break/smash the window”
