While pulling out of the garage, a warning message "chasis stabilization: drive moderately" appeared on the dash and had no power steering and was making whirring noise when the steering wheel was turned. stopped the car and walked back into the garage and found a sheared off bolt on the floor. upon further inspection, found all the three bolts on the electric steering motor sheared off & missing and the steering motor was about to fall off from its place and excessive corrosion was also noticed. the one bolt found on the garage floor must have been the last one holding the motor in place. glad this happened on the driveway and not at freeway speeds or when making a turn.
