The power steering of the vehicle suddenly stopped working. We had the car towed, and after inspection we were told that the steering column had failed. We were expected to purchase a new original part from Hyundai, which we did. After waiting a week, we were told that the replacement that was sent did not work and was defective. This has happened again and again, and we are currently waiting for our 4th part from Hyundai. Hyundai corporate told our auto shop that they ‘opened a case’ to see why these parts are defective. I’m hoping that they eventually get to the bottom of this and can fix our Tuscan. We were lucky that our steering column failed on the driveway at our home, but I would imagine it could case quite a bad accident if power steering went out suddenly on someone else.
