| Steering problems |
The electric power steering (eps) gear assembly / rack and pinion failed completely. Yes, the component is available for inspection upon request; it is currently located at the servicing dealership. A total failure of the steering gear assembly caused immediate loss of power steering assist, making the vehicle extremely heavy, rigid, and difficult to steer or control. This sudden mechanical/electronic failure puts the driver, passengers, and other motorists at extreme risk of a collision, especially if it occurs at highway speeds or while negotiating a turn. This did fail on me driving down the highway! yes. The problem was officially diagnosed and confirmed by the franchise dealership. They quoted $3,500 to replace the failed assembly. The vehicle displayed a "service power steering" warning message on the dashboard alongside an immediate loss of steering power assist. The failure happened suddenly while driving with no prior mechanical warning signs, symptoms, or gradual degradation.
While driving, the dash warning "service power steering" light up and my steering wheel locked making me unable to steer or manuever the car to safety. I was stuck in the middle of the road. I turned it off and on and was able to make it to a parking lot where the same safety messages illuminated four more times. I tried reversing and the same steering lock occurred again making me unable to drive the vehicle.
