Battery dead soon?

[ZeroSugar]

My Model X 75D is showing only 276km/170 mi rated range when charged full 100%. With really careful driving I can achieve ~200km/120 mi. 20" Michelin tires. 15°C/59°F

It's 2018 model. Battery is still under warranty, but is there any place to check if battery warranty is only for dead battery or also for reduced range.

There is no warranty on capacity with the 2018 on the other hand the warranty it does have is unlimited miles for 8 years vs the newer 70% capacity 8 year/150K mile warranty that started in 2020.

If you can scan the BMS with an Elm327 and an adapter able, you might want to check the cell voltage at 100% to make sure you're not being charge capped like the 85s were. 100% charge is a cell voltage of 4.2. If you're showing less than that at 100%, you're being limited via software.
