Segway Ninebot S Steering malfunction
 

My ninebot recently started steering left out of no where. I'll be riding and all the sudden the unit goes left. After jump off the unit will still slowly go in a circle to the left. Powering the unit off and on stops the unmanned unit for some time but comes back randomly. I also feel like as I am riding I am constantly compensating by leaning right with my left thigh. I have about 900 miles on this unit. What could be causing this problem?

Not sure if you figured this out yet but I've had a similar issue. I generally have to recalibrate every week or two.

Turn unit over and hold it level. Press power button to turn on. Wheels will spin in opposite directions, then change directions. Let this happen for about 10 seconds. Press power button and turn off. Set it back on it's wheels and power up and you should be good to go.
