Solution

1. Preparation

Gather tools required for the repair.
Ensure the vehicle is parked on a flat surface and the engine is off.
Disconnect the battery to prevent any electrical issues.

2. Access the Hood Latch

Open the hood if possible; if not, proceed to the next step with the latch still engaged.
Remove any plastic covers or trim pieces that obstruct access to the latch.

3. Clean and Lubricate the Latch Mechanism

Use a degreaser to clean the latch assembly, removing any grease, dirt, or corrosion.
Apply a silicone-based lubricant or white lithium grease to the latch mechanism, ensuring it penetrates all moving parts.

4. Inspect and Adjust the Cable

Check the cable for fraying or binding; if damaged, replace the cable.
If the cable is functional, ensure it has enough slack and is not pinched or excessively tight.

5. Reassemble and Test

Reattach any covers or trim that were removed to access the latch.
Reconnect the battery.
Test the latch operation by pulling the interior release lever and ensuring it releases the latch smoothly.
