What Are the Signs of a Malfunctioning Car Door Latch?

A malfunctioning car door latch can present several noticeable symptoms. If you observe any of these issues, it’s essential to investigate further:

• Difficulty in Opening or Closing: If your car door is hard to open or close, it might be due to a faulty latch. You may need to apply excessive force or hear unusual noises during operation.
• Door Not Staying Closed: A door that won’t stay shut is a clear indicator of latch problems. This issue poses a significant safety risk, especially while driving.
• Unusual Noises: Clicking, rattling, or grinding sounds when operating the door can signal that the latch mechanism is worn or damaged.
