We bought it slightly used had it 2 years. There are no foreign objects anywhere that would interfere with its operation. I have turned the power switch off by steering wheel and that doesn’t stop it. I have taken the battery out of key fob and that doesn’t stop it. It opens all the way stays open for a few minutes then closes back and locks. Then repeats. My wife does wash her car regularly.need some more info.
is this a new purchase? bought it used?
did it always behave this way? just started?
check the lock on the back to make sure there is nothing in the latch?
do you have children? could they have placed something inside the slit the hatch arm is in?
been to the car wash recently? water may have gotten into the mechanism and is causing the hatch to open.
have you done any troubleshooting steps or are you just going by what your wife has said to you?
your issue is not common, so this is why more info is needed.
