Solution

1. Preparation

Tools Needed: None specific, but access to the Tesla app for diagnostics is recommended.
Ensure the vehicle is parked in a well-ventilated area.
Allow the vehicle to cool down before inspection.

2. Cabin Air Filter Inspection

Locate the cabin air filter access panel, usually behind the glove compartment.
Remove the glove compartment by releasing the retaining clips.
Take out the cabin air filter and inspect it for dirt or damage.
If clogged, replace it with a new OEM filter.

3. Check for Foreign Objects

Visually inspect the undercarriage and wheel wells for any debris or foreign objects that may be causing the smell.
Remove any items found and ensure the area is clear.

4. Monitor Electric Motor and Battery

Use the Tesla app to check the battery and motor temperatures.
If temperatures are higher than normal, it may indicate a cooling issue.
If overheating is detected, inspect the cooling system for leaks or blockages.

5. Brake Component Inspection

Inspect the brake calipers and pads for signs of excessive wear or overheating.
If burnt odor is detected, consider replacing worn brake components with OEM parts.

6. HVAC System Cleaning

Inspect the HVAC system for mold or mildew buildup.
Run the HVAC system with the AC off at maximum temperature to dry out any moisture.
If odors persist, consider using an HVAC cleaning solution per manufacturer instructions.
