Estimated Time

2-4 hours

⚠️ Safety Warnings

Important safety information - read before proceeding

•Disconnect the battery before working on electrical systems.
•Allow the vehicle to cool down before inspecting brake components.

Symptoms

•Burning smell noticeable after driving
•Possible smoke or heat emanating from wheels or undercarriage
•Reduced braking performance (if related to brakes)
•Warning lights illuminated on the dashboard
•Unusual noises coming from the drivetrain or brakes

Diagnostic Steps

1
Inspect the exterior for any visible smoke or signs of burning, particularly around the wheels and undercarriage.
2
Check for any error codes using an OBD-II scanner or Tesla's diagnostic tools to identify potential electrical issues.
3
Inspect the brake components visually for signs of wear, overheating, or damage.
4
Verify the condition of the high-voltage battery and associated wiring for any signs of damage or overheating.
5
Test drive the vehicle to replicate the conditions under which the burning smell occurs, noting any specific changes in performance.

Solution

💡 Expert Tip

For complex repairs like this, consider taking photos at each step. This helps if you need to reverse a step or consult with a mechanic. Also, keep all removed parts organized - you may need to reference them during reassembly.

Verification

After completing the repair, verify that the issue has been resolved:

✓Test the affected component to ensure it functions correctly
✓Check for any error codes or warning lights
✓Monitor the vehicle for a few days to ensure the issue does not recur

Prevention Tips

To prevent this issue from occurring again:

•Follow the manufacturer's recommended maintenance schedule
•Address warning signs early before they develop into major issues
•Use quality parts and fluids recommended for your vehicle
•Keep detailed records of all repairs and maintenance

Solution

1. Preparation

Tools Required: OBD-II scanner, flashlight, multimeter, basic hand tools (sockets, wrenches)
Park the vehicle on a flat surface and ensure it is in "Park" mode.
Disconnect the vehicle from any charging source if applicable.
Allow the vehicle to cool down if it has been driven recently.

2. Brake Inspection

Remove the wheel covers and inspect the brake components:
- Check brake pads for excessive wear; replace if they are below the manufacturer's minimum thickness.
- Inspect rotors for signs of glazing, cracking, or overheating. If damaged, replace.
- Ensure calipers are functioning correctly and not sticking.
Reassemble the wheel cover after inspection and replacement.

3. Electrical System Inspection

Use a multimeter to check for continuity and voltage in the high-voltage battery connections.
Visually inspect all wiring harnesses for any signs of fraying or damage.
If any wires are damaged, repair or replace them as necessary.

4. Test Drive and Monitor

Reconnect the vehicle to the charging source if disconnected.
Perform a short test drive, monitoring for any return of the burning smell or unusual noises.
If the smell persists, further inspection of the drivetrain components may be required.
