Later on there's a noise coming from back seat ,I went to dealer and try to find out ,they did a good job found out they need to replace the whole rare end,and also found 2 wheels bent including the new wheel I just replaced,and another crack on one of the rare wheel which I think caused by the rare end issue ,and…
When driving on an open 2 lane county road at approximately 35-40 mph the automatic emergency braking engaged and fully stopped the car for no reason. There was nothing in the road, I did not have cruise control on. The vehicle just stopped and beeped.
