During an emergency break, when applying full force to the break, and the vehicle is traveling at 20 or less mph, the vehicle cannot come to a full stop. Automatic Emergency Braking and pre-collision warning failed to engage. When pressing the break with full force, loud noise of all the break pads grinding can be heard. Under the same condition, pre-collision warning would sometimes be activated and sometimes doesn't. When using the car's auto parking feature, multiple sensors would have delayed warnings, and the car will not break when getting dangerously close to objects. The vehicle has been examed multiple times by the dealer regarding increased break distance and occasion grinding noise when breaking (regardless of the speed), no problem was found and the vehicle is therefore determined to be safe to drive.
