Just wanted to report a complete motor failure on a Zero XU 2.8 after < 6000 miles.
Some details:
~5500 miles on the ODO after about 1 year of driving
Drive every day as a primary vehicle, twice a day, ~10 miles each way
While driving to work at about 35 mph the motor made a sort of grinding feeling/noise and quickly slowed to a stop (tire did not lockup, thankfully). After this, the motor became very high resistance to move/push. I have been without bike for a couple weeks now while the dealer is waiting on a replacement motor to be shipped from Zero.
Other issues seen so far:
-Front fork leaking after about 3000-4000 miles (not covered by warranty)
-Battery recalled for sealing issue, replacement battery has roughly 10-15% less capacity than original
-Firmware experienced occasional glitches when starting the bike, cutting out and displaying 0% even on a full charge, etc.
-Experienced a charging issue where the battery would not charge, BMS replaced under warranty.
I have to say after being very excited for this bike, and enjoying driving it on a daily basis (I still really enjoy it) - it seems almost every major component (suspension, battery, motor, controller) has had issues. This is a bit disheartening as one of the primary reasons for purchasing this bike was the "maintenance free" aspect and "higher reliability" vs. a gas bike. I suppose this is the burden of an early adopter.
Zero seems to have a lot of promise and I hope they continue to make new bikes, hopefully they can get their quality control in line.
