My 2010 MDX's alarm keeps going off randomly. We have had to keep it unlocked to avoid it happening. It's at the dealership now and they said it might be the hood latch? They offered two options $300 parts + 2 hours labor to replace latch? Or think $100 to turn off the alarm system? What are my options? Looks like the latch is $80 online? How hard is it to replace and is this the problem? Thanks!
