I found the problem!
Thanks for the input guys. While checking out your ideas, Tom's remark about "wobble" came to mind. I found I could wobble the hood slightly side to side near the front by hand. I found the two little ajustable "feet" and determined neither foot was making contact!
The little "feet" at each front corner of the underside of my hood needed to be adjusted (screwed) out so both just contacted the brace the hood latch is on. I made sure the hood was level, feet locked in position with the locknuts, and the hood still latched securely when closed.
Hope my solution works for others!
