Loving my new ebike that I’ve had about a month. But having some issues the last few days.
Today the rear tire went completely flat. Aired it up and it instantly deflated. It seems to be coming from the valve area. Do I need to replace the tube? Can I fix the valve? I’m new to bikes but fairly handy. Not sure if I need to remove the wheel to inspect the tube.
I air it up and it deflates very quickly and can hear air escaping from valve or area under the rim. I do see the indentation in the tire when inflated. Not sure what that’s about.
Also the front rotor or caliper is scraping. Should that go away with more use? Not sure if rotor is vent or caliper or pads are misaligned. Any help on either of these issues appreciated. Can’t believe Trek doesn’t have detailed owners Manuals for each model. It’s a $2500 bike

Pads probably just misaligned. Based on your post I’d assume you don’t have much experience working on your own bikes, so I’d just take it in to the shop to have them swap the tube, check the tire for anything stuck in it, and realigning the rotor pads
Removing the wheel, tire, and tube would give you a better idea if a new tube is needed. Then you can inflate it and see what’s happening.
The rubbing is most likely your rotar rubbing the pad. You could either Google adjustment for whatever brake you have, or Park Tool has basically any bike maintenance you can think of in video form between their website and YouTube.
The reason Trek doesn’t give a detailed owners manual is because of three main factors; The biggest would be that they don’t manufacture the components, so it’s not really their place to tell you how to maintain it. Secondly, especially during covid, the components could change if they have supply issues, run out of something, etc. Thirdly, and the most unfortunate reason, you’re more likely to have to go back to their shop for maintenance without detailed information.
