Is it the inverter whine? Mine does the same thing at very similar speeds and was confirmed as normal from the inverter. Makes sense but it's unfortunate they tuned the motor pulse that way.
I find the difference in soft to moderate to be more in the side-to-side body control rather than the overall compliance. In soft the sway bar is way too disconnected if I want take corners more aggressively. In a straight line it's going to be harder to tell. If you're driving across a bunch of...
This is normal gps behavior on a cold start (got to acquire 7 or so satellites) I've noticed when using a covered garage. But why they don't keep a cache is a mystery.
Service center fixed mine, a very common issue. Now I only get it rarely, it'll still rattle but only once or twice instead of repeatedly on the roughest washboard.
I've had a similar issue that got fixed when they found a broken clip inside the steering wheel. Took 2 tries. I had to get lucky enough to reproduce it at the service center.
Did a similar trip to Page. Wasn't able to charge there but you could always book one of the many RV camp sites or give yourself buffer to get to Kayenta and do monument valley later. I made it to Page with 50% but that wouldn't have been enough to get back uphill to Flagstaff.
I've done this and it's fun. The only weird thing is it will reduce power if you over rotate and depress the pedal again, so just keep it under power. You need to jab the throttle at least half way down to get the rear overpowering the front. I prefer the low regen for this stuff.
Accidentally stopped here a week before it opened to use the V4 stations. It's a nice place and one of the cheapest sites (with membership). Those V4 are definitely stiffer and harder to pull out and I've seen drivers leave after struggling to unplug them lol.
