I experienced something very frightening yesterday 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 issue Honda Accord Steering - 2013 HONDA ACCORD Problems With Steering many this happened several times in a row.
It seems like there are 2 possible scenarios at play:
1) this is a symptom of the EPS system beginning to fail. This would imply I am likely to see this issue repeat, eventually resulting in a complete failure of the EPS. 2) This is some known event that occurs with some incredibly low probability. I am no more likely to experience this again vs a brand new EPS system.
It sounded like the dealer thought this was in category 2 (freak event).. If that is the case what is the chances of this happening?? Why have so many customers reported this happening 2 or 3 times in a short timespan?
It seems to me case 1 is the more likely scenario.
What should I do next?
