Solution

1. Preparation

Gather necessary tools and parts.
Ensure the car is parked on a level surface and turn off the vehicle.
Disconnect the 12V battery to avoid any electrical issues during repairs.

2. Inspect and Replace Motor Mounts

Remove the front trunk liner to access the motor mounts.
Use a socket set to remove the bolts securing the motor mounts.
Carefully lift the motor slightly using a jack to relieve tension from the mounts.
Replace the old motor mounts with new ones, ensuring they are aligned properly.
Torque the bolts to the manufacturer's specified torque settings.

3. Inspect the Battery Connections

Check the battery terminals for corrosion and ensure they are tight.
Clean the terminals if necessary using a wire brush and reapply dielectric grease.
Inspect the high-voltage connections for any signs of wear or arcing.

4. Suspension Check

Examine the suspension components including struts, shocks, and bushings.
Replace any worn or damaged components using appropriate tools.
Re-align the vehicle if suspension components were replaced.

5. Tire Balance and Condition

Remove the wheels and inspect the tires for uneven wear.
Balance the tires using a tire balancer.
Replace tires if they are excessively worn or damaged.
