I was driving to work the other morning and noticed a new annoying rattle coming from the rear of the car. It was so annoying I soon pulled over to see WTH. That is when I discovered that the rear hatch was not latched.
After making sure the hatch was properly latched... no more rattles! The hatch was not designed to drive with it unlatched.

Beware of exhaust gasses entering unnoticed from open rear hatch. This could be a hazardous situation.
