Electrical

Estimated Time

1-2 hours

⚠️ Safety Warnings

Important safety information - read before proceeding

•Ensure the vehicle is stationary and in park before performing any checks or updates.

Symptoms

•Significant drop in estimated range displayed on dashboard
•Increased frequency of charging required
•Unexpected battery drain when parked (phantom drain)
•Slower charging speed observed at charging stations
•Notification messages regarding battery health or energy usage

Diagnostic Steps

1
Verify the current software version and check for updates in the vehicle settings.
2
Examine energy consumption statistics in the vehicle’s display to identify any unusual energy usage patterns.
3
Inspect the settings for climate control and ensure that features like preconditioning are disabled when not needed.
4
Check for any active apps or features that may be consuming battery in the background (e.g., navigation, streaming services).
5
Run a battery health check via the Tesla app or vehicle settings to assess the overall battery condition.
6
Inspect tire pressures and ensure they are set to the recommended levels, as under-inflated tires can affect range.

Solution

Solution

1. Preparation

Tools Required: Tesla app, tire pressure gauge, tire inflator (if needed)
Ensure the vehicle is parked in a safe location and the key fob is available.

2. Software Update

Access the vehicle’s settings via the touchscreen.
Navigate to 'Software' and check for any available updates.
If an update is available, follow the prompts to install it, ensuring the vehicle remains in park during the update process.

3. Optimize Energy Settings

On the touchscreen, go to 'Climate' settings and disable preconditioning if not in use.
Access 'Driving' settings to review energy-saving modes and ensure they are enabled.
Review the 'Energy' app to identify any recent trips that show unusually high energy consumption and adjust driving habits accordingly.

4. Battery Health Check

Use the Tesla app to request a battery health check.
Follow any recommendations provided by the app regarding battery maintenance or service if necessary.

5. Tire Inspection

Use a tire pressure gauge to check the pressure of all four tires.
Inflate any tires that are below the recommended pressure (found on the driver’s door jamb).
If tires are excessively worn or damaged, consider replacement.
