Solution

1. Preparation

Gather necessary tools and materials.
Ensure the vehicle is parked on a level surface and engage the parking brake.
Put on gloves and safety goggles for protection.

2. Inspect Engine and Components

Sub-steps:
1. Open the front trunk and remove any covers to access the electric motor and transmission.
2. Visually inspect the motor and transmission for any signs of oil pooling or wetness.
3. Check the seals around the motor and transmission for cracks or wear.

3. Check Oil Filter and Pan

Sub-steps:
1. Inspect the oil filter for tightness and signs of leaking; replace if necessary.
2. Use a ratchet and socket to remove the oil drain plug and inspect for any signs of leakage at the oil pan.
3. Replace the drain plug and torque it to the manufacturer's specifications (usually around 20-30 lb-ft).

4. Use UV Dye for Hard-to-Find Leaks

Sub-steps:
1. Add UV dye to the oil through the oil filler cap.
2. Run the vehicle for a short period to circulate the dye.
3. Use a UV light to inspect the engine and transmission areas for any glowing leaks.

5. Clean and Monitor

Sub-steps:
1. Clean any visible oil residue using an appropriate degreaser.
2. Monitor the vehicle over a few days after the inspection to check for the reappearance of leaks.
