why does my Tesla Model 3 Highland (2024-present) show a low tire pressure warning

Solution

1. Preparation

• Gather necessary tools: tire pressure gauge, air compressor, and a tire repair kit if needed.
• Ensure the vehicle is parked on a level surface and the tires are cool for accurate pressure readings.

2. Check and Inflate Tires

• Sub-steps:
  1. Use the tire pressure gauge to measure the air pressure in each tire.
  2. Compare the readings with the manufacturer's recommended tire pressure (found on the driver’s door jamb).
  3. If any tire is underinflated, use an air compressor to inflate it to the correct pressure.
  4. If a tire has a significant drop in pressure, inspect it closely for punctures or damage.

3. Inspect and Replace TPMS Sensors (if necessary)

• Sub-steps:
  1. If a tire appears fine but the warning persists, the TPMS sensor may be faulty.
  2. Remove the tire from the wheel (if required) to access the TPMS sensor.
  3. Replace the TPMS sensor with a new one if it is damaged or malfunctioning.
  4. Reinstall the tire and ensure it is properly sealed.

4. Reset TPMS

• Sub-steps:
  1. After addressing the tire pressure and TPMS sensors, reset the TPMS using the vehicle’s settings menu.
  2. Follow the on-screen prompts to complete the reset.
