There is a pulsing feel in the brakes. Have checked online and realized that it seems to be a common enough complaint by other owners. On hard stops the push back by the pedal is hard enough that the brakes lockup intermittently. This is different from the pulsing feel of the anti-lock system. It feels as though the rotors are warped. It is felt in the steering wheel also, and increasingly in the vehicle in normal driving without applying the brakes. It is not the tires which are fastidiously kept new omi. No incident yet but I believe there is a trend that needs to be investigated.
There was a severe pulsation in the rear of the vehicle when the brake were applied. The dealership serviced the vehicle over 20 times.
