Solution

1. Preparation

Ensure the vehicle is parked on a level surface and in "Park" mode.
Connect to a charger if battery levels are low.

2. Software Update

Navigate to "Software" in the vehicle settings.
Check for and install any available updates to ensure the vehicle's software is current.
Reboot the infotainment system if necessary by holding down both scroll wheels on the steering wheel.

3. Battery Inspection

Access the battery compartment if necessary to inspect for physical damage or corrosion.
If the battery SOC is low, charge the vehicle to at least 80% to optimize performance.
Use the Tesla app to check battery health; consider scheduling a service appointment if significant degradation is noted.

4. Throttle Calibration

From the vehicle settings, reset throttle response by navigating to the "Driving" section.
Select "Reset" for the acceleration profile settings to restore factory defaults.
