On approximately six different occasions, the collision avoidance system has been triggered erroneously, when no other vehicles were near my car, to the point that the audible and visual alarms were triggered, my driver's seatbelt pulled me back against the driver's seat, two of those times the car swerved itself and another two of those times the car braked itself, without any prompting from the driver to do so. the dealership told me today that because the system works on radar that sometimes this will happen. i believe that these systems need to be practically error proof because if the car brakes itself, or swerves itself, without any action from the driver it could potentially *cause* an accident. not to mention that it's very scary when it happens and then there has to be some emotional recovery as a driver to overcome these episodes. the car has about 1000 miles on it. all of these incidents happened on city streets, while the car was going anywhere from 25-45 mph.
While driving at approximately 60 mph with no car within 200 yards in front of vehicle, no object on the road, and no collision was imminent, the vehicle suddenly and spontaneously slowed down to almost 5 mph from about 60 mph for no reason. the seat belts pretensioned, the gas pedal dropped out from driver's feet. city safety activated. all occupants developed mild whiplash. it took several second to get car to return to highway speeds. dealer claims it was due to a toll tag that was placed to closely to the city safety system near the rear view mirror. ...updated 12/03/15 *bf *cn
