Solution

1. Preparation

Ensure the vehicle is in park (automatic) or neutral (manual).
Gather necessary tools and parts.
Disconnect the battery to prevent electrical shock.

2. Battery Inspection and Replacement

Inspect Battery Terminals:
- Clean corrosion from battery terminals using a wire brush.
- Tighten any loose connections.
Battery Replacement:
- If the battery voltage is low, replace it with a new, fully charged battery.
- Ensure the new battery is rated for the Genesis G70.

3. Starter Inspection

Remove the Starter:
- Locate the starter motor (usually under the vehicle near the transmission).
- Remove the starter wiring connections using a socket set.
- Unbolt the starter from its mount and remove it from the vehicle.
Test the Starter:
- Use a multimeter to check for continuity and proper voltage at the starter terminals.
- If the starter is faulty, replace it with a new or refurbished starter.

4. Reassembly

Reinstall the starter in reverse order of removal, ensuring all bolts are secured to the manufacturer’s torque specifications.
Reconnect battery terminals ensuring they are tight and clean.

5. Final Checks

Reconnect the battery and attempt to start the vehicle.
If the issue persists, proceed with further diagnostics on the ignition switch or wiring.
