Mazda 3 trunk problem

[dumbone95]

So I recently just bought a 2010 mazdaspeed 3 everything been great, but lately I noticed when I turn off the car the trunk keeps opening and closing by it's self, I tried searching couldn't fine anything, has anyone had this problem ?

Should be still in warranty. Haven't heard of this problem before.

did you recently get a remote start installed? or anything electrical installed?

does the hatch actually open or does the lock just release? your door locks unlock when you turn your car off, sounds like power is feeding to your hatch release from the door locks, take it in and have the dealer look at it.

Had the same problem, one shop said nothing they could do LOL... but it fixed itself, i think maybe something to do with ice or cold weather. Mine was a 2010 Mazda hatchback.
