So glad it worked @jojo33!! quick update - about 50 miles later - it came back just the other day - the jerking left/right. But it was an incredibly hot day and I’m guessing it affected the viscosity of the grease. It seems to be fine now. Overall I call it a huge success. Thanks for documenting the process!!

I've had this same EXACT issue for a couple years now.. hard jerk left/right steering on the Mini Pro: I've had an ongoing issue with my Mini Pro suddenly jerking to the left or right - for over 2 years. I replaced the Hall sensor and housing twice, which worked for a short time. I finally think it's solved! You have to remove the battery, front and rear fascia, foot pads, steering arm and center tower to get to the steering housing - then apply dampening grease to create resistance (found on Amazon)... Total disassembly/reassembly time "on the bench" for me, having done it no less than 3 times, was about an hour. My theory is that over time, the factory grease breaks down - i've had mine since 2018 and this started a couple years ago.. When this happens, the lack of resistance causes the steering shaft to become ultra sensitive - any bump, stick or other debris you roll over can shift the balance of the unit, which then gets transferred to the steering shaft. Even your body/knees just slightly touching the steering bar will become "amplified" because there is no resistance to dampen the movement.. Just a theory - but since applying a generous amount of this grease, the steering bar is now TIGHT-A-F - like new condition.. - hopefully this will help someone else

oops - worth mentioning before someone comments on the video as it shows me pressing on the pad because I am holding the battery. I've actually screwed the battery-on so that I don't touch the pad and it behaves the same way. thanks again!

Hoping someone else has had this issue and can recommend any tests.. Segway MiniPro won't power down I've tried: removing/replacing battery power button works, tries to power down, then just doesn't feels like a bad foot pad sensor- eg: it behaves as if someone is still standing on it i'm fairly technical and have a good multimeter - does anyone know if i can measure the resistance or something else on the individual sensors to see if they are malfunctioning? At the very minimum i was going to poke around and try to measure each sensor and see if they are consistent I've had it completely apart and do not see any foreign elements under the pads or in the recessed area under the pads where the sensor button goes recalibrated more times than I can count performs as expected, wheels rotate opposite direction, etc when placed upright - everything appears to work correctly - just won't turn off cannot see any error codes/lights flashing the app isn't able to turn if off either no sw updates applied immediately prior to the issue surfacing Here is a link to a video showing above symptoms thanks in advance!!!
