Single point of failure where ground wire disconnected from ecm and car lost 100% functionality and shut down completely while operating/driving while stopped at a red light. hazards warning lights were non operable therefore my concern is if airbags would of even actuated if a rear end accident would of occurred since the vehicle had no functionality. issue caused major traffic back up and police had to have vehicle towed to dealer. while waiting for tow truck, i had to climb over center console to manually open rear door to remove my toddler from stranded vehicle on a main road (13 mile and drake, farmington hills). i already voiced a corporate complaint with ford and they did nothing to resolve issue or put me into an equivalent vehicle. the vehicle has also had previous odd/screaching rear axle noises and brake sticking/locking up issues when putting into reverse after parked overnight and has been into the dealer 2-3x for this issue. vehicle is <6 months old.
