⚠️ Safety Warnings

Important safety information - read before proceeding

•Ensure the vehicle is parked in a safe location while performing checks and updates.

Symptoms

•Significant reduction in estimated range on the dashboard
•Increased frequency of needing to charge
•Battery charge percentage dropping quickly even with minimal use
•Heating or cooling system usage affecting range more than usual
•Possible alerts or notifications related to battery performance

Diagnostic Steps

1
Check the current battery health status using the Tesla app or onboard diagnostics.
2
Review the history of charging patterns and usage statistics in the Tesla app.
3
Inspect for any software updates available for the vehicle.
4
Analyze driving habits and conditions (e.g., excessive acceleration, high speed).
5
Check tire pressure and condition, as improper inflation can affect efficiency.
6
Evaluate the impact of external temperatures on battery performance, considering extreme cold or heat.

Solution
