Could really use some direction and guidance please.

2,500 miles on bike/motor from new, motor and case never opened. So far, had been trouble-free, vintage 2017/2018 (or so). Bike built by FLX (San Diego, CA), Blade 1.0 e-MTB. Daily 8 mile commute to work.

Symptoms:
1. Motor 'clicks' generally once, when transitioning from pedaling to coasting - frequently, but not all the time.
2. Motor 'sticks' sometimes/semi-often when free-pedaling backwards (like when adjusting pedal position for a turn).

Possibly: Pawls? Pawl Springs?

Assessment of problem? Easy to fix? Critical to fix now or soon? Is YouTube my friend? Parts Source?

Thanks in advance!
