If it’s a standard range model y? If so 180 miles range isn’t that’s far out of expectation if it’s not being driven particularly economically. If your not used to driving a BEV then your probably not getting the most out of it.
If it’s the long range dual motor, you’d have to be driving it pretty hard to only get 180 miles out of it.
I have a standard range model 3 and I did around 220 miles today with 3 stops and got back with 14%. Driven to the speed limit the whole way. Yeh, I’ll get more out of it than a model Y, but it’s not that much more.
The tesla nav only sends you to their own chargers, great if they are en-route, not so much if not. There are plenty of other decent sites out there once you get to know where they are.
There are no standard range Model Y's in the UK at the moment. Only LR Model Y. (Dual Motor) - Performance Models are due next around end of the year. No ETA on standard range Y's in the UK.
180 Miles on Y seems extremely low unless he was driving very quickly.....
I've got 280 from 100% to 11% on mine motorway driving etc - No problem. So in theory around 300 would be doable in summer time - range drops around 10% in winter time due to wind/rain/cold etc - But should still easy get 250 miles out of it.
