Hi there,
Thank you for the donation,
Unfortunately Mitchell 1 dose not as yet cover 2010 Subaru interiors, but I would be thinking that either the thread is stripped or there is an encapsulated nut that is turning, I would contact the dealer or drop in and show them, you may just have a warranty repair on your hands, I have looked on line as well and have found nothing that covers this problem.
