Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is in park (automatic) or neutral (manual) with the parking brake engaged.
Disconnect the battery negative terminal to avoid electrical shock.

2. Battery Inspection and Replacement

Inspect the battery for physical damage, leaks, or bulging.
Clean the battery terminals using a wire brush and a mixture of baking soda and water to remove corrosion.
Reconnect the terminals securely.
If the battery is found to be faulty during the load test, replace it with a new battery of the same specifications (usually a Group 35 battery for this model).

3. Starter Motor Inspection and Replacement

If the battery is good, locate the starter motor (usually found near the engine's oil pan).
Remove the electrical connections to the starter (a 10mm or 12mm socket may be required).
Unbolt the starter from the engine using the appropriate socket size (usually 14mm or 17mm).
Install the new starter by reversing the removal steps; torque the bolts to manufacturer specifications (typically around 15-25 ft-lbs).
Reconnect the battery terminals.

4. Testing

Reconnect the battery negative terminal.
Attempt to start the vehicle to ensure the new battery/starter functions properly.
