I am writing to report a serious and recurring safety issue with my 2016 Ford Transit Connect. On four separate occasions, the rear sliding doors on both the driver and passenger sides have completely detached from the vehicle during the normal process of closing them. These incidents occurred without the application of any excessive force or unusual use. The doors unexpectedly slid off their tracks and fell from the vehicle, creating a dangerous situation. Each time this occurred, my family was left stranded, unable to complete our trip or return home safely. As a result of this repeated failure, I have avoided using one of the sliding doors for over a year out of fear that it was not properly re-secured and could fall off again. This issue represents a significant safety concern, particularly for families relying on this vehicle for daily transportation, and I believe it warrants immediate attention and investigation.
