I was driving to burlington MA on August 29, 2019 and, while making a right turn to enter onto rte 3 northbound, I lost all my power steering. At the moment of failure, the steering wheel snapped abruptly to the left almost causing me to hit the guard rail. Fortunately, I was able to wrestle/turn the steering wheel to the right and avoid an accident. I had no power steering all the way home. When I wrestled the car into my driveway at home, I shut it off, waited a minute and restarted the car. The dash idiot light was off and the power steering was working. I have not used and don't plan on using the car until this problem is fixed. I made an appointment to have this problem diagnosed and repaired on September 9, 2019. I believe the cause of the catastrophic failure is related to the sensors on the steering wheel column that communicate with the computer which controls the electric rack and pinion system.
