Common eBike problems and solutions

Hey everyone!

I've been riding my [mention your ebike type, e.g., Aventon Pace 500, Specialized Turbo Levo] for about [distance/time, e.g., 1,500 miles, a year now] mostly on [terrain, e.g., paved trails and some light gravel], and it's been fantastic. However, I've started wondering about common issues other riders face, especially when comparing different brands. Are there certain problems you've noticed are more prevalent with specific eBike brands (e.g., battery degradation, motor issues, controller glitches), and what solutions have you found? I'm curious if some brands are just more robust or if certain components are universally problematic.
