Odd one this, to me at least. Whenever I return to my 2007 XKR Conv after leaving it sitting (locked) for a while and open the boot/trunk, after I close it it unlatches and pops back open after a second. Doesn't do it every time, but once it starts it it will keep on happening until I unlock the car.

At the same time I noticed the passenger airbag light stays on and I get nagged about the passenger seatbelt, even though there's no-one sitting there. I bring this up as well as the commonality seems to be electrical glitches.

Any ideas? Thanks.
