Common Issues

  • Sticking or Jammed Doors: Can be caused by misaligned latches, worn hinges, or damaged seals.

Regular Checks

  • Power Locks: Test for responsive operation and listen for any unusual noises.

Addressing Problems

  • Sticking Locks: Lubricate with graphite powder or silicone-based lubricant.

Emergency Exit

Ensure all passengers can easily open doors from the inside. Regularly check child safety locks if your vehicle is equipped with them.

Seasonal Considerations
