Reduced Range in Cold Weather
The Tesla Model 3 is experiencing a drop in range or efficiency during winter, which is a common issue 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 or heat pump systems) draws significant power, reducing range.
Cold tires have higher rolling resistance, and winter tires may increase drag, further reducing efficiency.
Battery management system may limit regenerative braking in cold weather to protect the battery, reducing energy recapture.
Preconditioning the battery or cabin while plugged in is not being used, leading to higher energy consumption from the battery.

What You Should Do
Precondition the car while plugged in before driving, use seat heaters instead of cabin heat when possible, ensure tires are properly inflated, and park in a garage if available.
Monitor energy usage via the vehicle's energy app to identify high consumption areas.
