The detent designed to hold the passenger side sliding door open has malfunctioned due to what the dealership describes as a manufacturing defect commonly found in the 2015 Ford Transit Connect XLT/LWB. Dealer states dealer is unable to correct. When parked on an incline, the sliding door can violently slide forward with a significant potential for injury to a passenger, especially a young child, entering or exiting the vehicle. Dealer suggests taking the vehicle to a body shop to correct this defect at owner's expense.
