ES2 - intermittant loss of power
 

I'm about 4 weeks into owning an ES2 using it for 4 miles a day.

Last week the electronic brake did not activate when needed but everything else worked fine so thought it was a one off.

Today things got much worse, both the power and brake would intermittantly not work when using the thumb controls but the display stayed on continually.

I haven't opened anything up but I would imaging this sounds like a loose connection somewhere.

Can anyone offer any similar experience to this? Is this a common issue that I can fix on my own?
