I purchased my Model 3 SR+ last June and it is updated to version 2020.24.6.9. There are two v3 supercharger stations within 20 minutes of me, both of which I have charged at several times. At both of these locations I have been unable to get above 75kW, even when my car is the only one charging and it's early in the morning. Both of these locations (Emeryville, CA - Powell Street Plaza Supercharger & Richmond, CA - Pierce Street Supercharger) are listed as "up to 250kW" on the Tesla website. It is my understanding that SR+ cars updated as of last December are supposed to peak around 150kW at v3 superchargers. Websites such as the EV database confirm that this should be expected performance.
I called Tesla support and they gave me a long list of suggestions of how to improve the supercharging on the car (go when others aren't there, precondition the battery through the map, etc.) all of which I have already done. They also told me all the ways in which the proprietors of the superchargers can throttle the power to the superchargers. Ultimately they ended up telling me that because the superchargers are rated at "up to 250kW", I shouldn't expect the charge to go up to that value. When I told them that I'm getting well below my SR+ expected value, I was told that they could run a diagnostic remotely right now, and that the car looks "perfect". I was then told I could bring the car into a service center to get another diagnostic if I wanted to, and that it would probably be covered by the warranty, but that couldn't be guaranteed.
Have other people had similar experiences? I love this car, but the battery has already degraded about 12% after one year and ~15,000 miles, which I know is already much more than the average. It's a bit concerning also to have Tesla assure me that the battery is "perfect" and to suggest that my performance can only be explained by other factors. Are there any suggestions on how to monitor my battery's health or get Tesla to seriously address my concerns?
