SuperCommuter with 5,080 miles now I've got a new motor

Felt funny, grindy, weird, after riding other e-bikes, mine felt in need.
Dealer had Bosch/Trek replace under warranty.
Reset to zero, like a brand new bike.
Glad I got a reputable Trek dealer as well as an honorable manufacturer, would not hesitate to recommend.

It's back in the shop.....after 300+ miles on the new motor, and each trip when going in 5th, 6th or 7th gear, pedaling hard (with effort), and after about 3-4 miles, noise is back in the left side of the crankcase.
My LBS has the bike and is using it to diagnose.
Sure hope it's something simple.

See my posting(s) in the trek sub-forum as well as the Bosch sub-forum, problems abound at 600 miles on new motor and all new components
