Vehicle suddenly puts on the brakes, for no reason. Has happened 3 times, 2 in parking lots and 1 while driving down the road, suddenly swerved for no reason. Could cause injuries to driver and passenger.
Almost once a month my car with think there is something in front of it and activate the emergency brakes. It causes huge strain to the brakes and almost makes me crash and puts the people in front of me and behind me at risk. I've turned the setting to a lower sensitivity to try to avoid this but it doesn't matter. The car does the worst on turns as well and thinks cars in the opposite lanes while turning are in your lane and will cause the system to react. On small roads the car will try to move your car to correct in the lane but it's too small and runs the risk of going off the road or go into oncoming traffic. Most of the time I just have to turn this setting off entirely since it's more dangerous than helpful.
