My wife went to local store and parked the car. When backing out of parking spot, she was unable to turn steering wheel !!!!. It happened on 12jan2017 with only 18,824 total miles. Car had to be loaded and hauled to local dealer due to steering failure. And the cause was, I quote or copy from dealer work order inspected and found belt hanging loose on engine. Found idler pulley bolt broken and pulley laying loose extracted broken bolt from block. Tapped threads to ensure none damage {end of copy} what happens here in az driving in the mt's around curves?? would they say OH he's old lost control and went over the edge and the crash broke the bolt. Or looking at cell phone crossed over center line hitting a semi head on. The crash broke the bolt. And never find out they have bad bolts in the steering system. I told several shop supervisors but they just shook there head. Are the bolts not harden correctly? was to much torque used for bolt size when installing?? are the bolts to small of a size for the job?? the bolt only had to hold the belt pulley tight on the serpentine belt. So that you can steer, run the generator and other things. T. But it snapped while parked or car was started. I am scared while I am driving the car. When can it happen again? car was in warranty and fixed at no charge.
