Reduced Range in Cold Weather
The Tesla Model Y is experiencing a drop in fuel economy (range) during winter, which is common for electric vehicles due to battery chemistry and increased energy demands for heating.
Diagnosis Details
Possible Causes
Cold temperatures reduce battery efficiency and capacity, as lithium-ion batteries perform optimally in moderate temperatures.
Increased use of cabin heating (especially resistive heating) and seat/steering warmers draws more energy from the battery.
Cold weather increases rolling resistance and aerodynamic drag (denser air), further reducing range.
Tire pressure drops in cold weather, increasing rolling resistance.
Battery management system may limit regenerative braking in cold conditions, reducing energy recapture.

What You Should Do
Precondition the battery while plugged in using the Tesla app before driving.
Use seat heaters instead of cabin heat to save energy.
Keep tires properly inflated.
Park in a garage if possible.
Enable 'Range Mode' in settings if available.
Monitor energy consumption via the trip meter.
