Purchased new 2014 qx60 hybrid equipped with technology package, including intelligent brake assist with forward collision warning, and distance control assist. initially the only issue was the vehicle hesitating when starting from a stop. the dealership claimed the vehicle needed a break-in period to optimize the engine and hybrid system. two weeks later as i was driving through a parking lot less than 15 mph, the driver seat belt suddenly pre-tensed tightly as i applied the brakes, suddenly pinning me to seat until vehicle was completely stopped. it happened again the next day when gently applying brake while driving at low speed on residential street. took vehicle to dealership and explained each time it happened when applying brakes at low speed with no vehicles or obstacles in vicinity. the dealership service checked the vehicle over 24 hours and could not detect the problem, returning the vehicle to me. after a week it began again, each time tightening quickly and pinning me into my seat until vehicle completely stopped. occurred randomly at speeds less than 20mph and no cars, pedestrians or obstacles near vehicle. no alarms, no warning and no reason. now afraid to drive the vehicle as it occurred as often as 3 times in less than 24hrs, i left my vehicle at dealership for service again. after several days, both service representative and service manager stated they were able to duplicate the problem and the seat belt is not communicating with airbag/safety system or recognize the hybrid system. service representative confirmed other qx60 hybrids detected same seat belt malfunctioning during manufacturing line test. my qx60 hybrid is still in dealership service after two weeks and they cannot determine cause of seat belt malfunctioning. *tr
