why does my Tesla Model 3 Highland (2024-present) have a delayed acceleration response?

Solution

1. Preparation

• Gather necessary tools and parts.
• Ensure the vehicle is in a safe, well-ventilated area.
• Disconnect the vehicle from any charging source.

2. Update Software

• Navigate to the vehicle settings and check for any available software updates.
• If an update is available, follow the on-screen prompts to install.
• Restart the vehicle if prompted after the update is complete.

3. Inspect Throttle Pedal Sensor

• Remove the cover under the dashboard to access the throttle pedal assembly.
• Disconnect the throttle pedal connector.
• Use a multimeter to test the sensor's resistance and ensure it’s within the manufacturer's specifications.
• If the sensor is faulty, replace it with a new one.
  • Tools Required: Multimeter, socket set
  • Safety Warnings: Disconnect battery before working on electrical systems.

4. Evaluate Battery Performance

• Use the Tesla diagnostics tool to check the battery's state of health and charge.
• If the battery shows signs of degradation, consider a battery replacement.

5. Adjust Regenerative Braking Settings

• Access the vehicle settings menu and review regenerative braking settings.
• Adjust the setting to a higher or lower level to see if it affects acceleration response.
• Test drive the vehicle to evaluate performance changes.
