Hi my name is Melanie and I have a 2012 GEM E4. Out of the blue, when I press on gas pedal there is alot of hesitation when accelerating. I have to release gas pedal and press again over and over. Plus the entire time the speedometer will show 0 then suddenly jump to 82 and a wrench symbol appears on the display. I have tried turning the main power switch off and back on but no luck.
Does anyone have any guidance on troubleshooting steps? Just know I am not super familiar with the mechanics so please be patient. 
82 check speed sensor and wiring or motor overloaded reset motor controller
That is what an 82 error is, Check you wiring at the motor, could also be a throttle pedal issue.
First guess is your magnet on end of motor . They are known to break . On the end of the motor , right in the middle is a round sensor with wire coming of it . Remove it and look in the motor . there is a round magnet . If it is broken you will need a new one . Pretty common .
