....it's not closed securely and it's lifting?

Get the catch thoroughly cleaned and lubed and make sure its secured, I bet its caked in oily muck.

I think there is a micro switch in the catch.

It gets dark early with this problem

The 159 bonnet catch was revised in 2008, but wasn't a recall, just replaced if playing up.
