Less than 70,000 miles on my vehicle, but recently took my car in for an alignment because my vehicle slowly drifts to the right, and sometimes the steering wheel shakes when driving between 50-60 miles. I was told by 2 different body shops (1 of which was Toyota) that my entire power steering would need to be replaced and is currently leaking. I was advised this could be potentially dangerous if my power steering were to stop working while I was driving at fast speeds on the freeway. I received a full-point inspection when my mileage was at the 50,000 marker but this was not an issue at that time.
