The vehicle had a repair made by dealership. The repair started to malfunction as it would lock the vehicles driving mechanism making the vehicle non opporstional while driving. Issue was reported to the same dealer and explained. The dealer stated that I would receive a call to schedule a mechanical appointment to investigate however the time spent waiting for further instructions from dealer. Days later the system lock while driving I the high way i95 and flew of an exit ramp high up and for deep of field. Loosing not just my conscious but came to fine out I got injured on my back and no one took the responsibility on something that could have been avoid as the vehicle was brought to dealer for inspection prior to the accident but their negligence let me drive off with the vehicle.
