I experienced something very frightening with my 2013 honda accord v6. While driving about 40mph in a straight line I suddenly lost power steering. I had the EPS light show on my dash. I pulled over and restarted the car 2 or 3 times before the power steering came back to normal. It hasn’t happened since. The sudden massive increase in steering wheel force required when EPS shuts off could potentially be very dangerous and I am now frightened to drive this car.
I brought the car to a honda dealer and they were able to confirm that an error code was logged after the incident:
DTC 71-01 Motor Angle Sensor (SIN/COS Signals)
Unfortunately they were not able to diagnose what the root cause of the above issue is. They followed all of the honda-supplied debugging procedures and ran a full reset & diagnostics on the EPS sub system. They weren’t able to find any problems with it and their conclusion that the issue was “intermittent” and that I should continue to drive the car. They made this sound as if it was some freak event that is extremely unlikely to occur.
I noticed several other customers have run into this same issue: http://www.arfc.org/complaints/2013/honda/accord/steering/problem.aspx and for many of them the issue repeated several times.
What should I do next?
