Hood Latch Problem

Yes, you could be on to something. I haven't seen one wear out but it is possible. But if it works hard as you describe, paint or dirt can jamb it up. If you can get it to work badly without the hood closed, then we have to suspect the latch. If so, then remove the whole latch from the car, clean it, inspect it. You can probably get it to bind up in your hand. Maybe we are headed to replacement. If so, there are many on this site that can help.
