What needs to be done from here first is to have the fault codes checked/read out to see what codes are set with this issue here.Once this has been done any codes set need diagnosed to locate and repair the fault here.This needs to be done using a scan tool that will plug in and communicate with all computers.I suspect there will be at least one code set that will help diagnose and locate the issue here.
This sounds like a possible trunk latch or roof sensor issue causing this here.I have seen the trunk latch fail before needing replaced.In some cases it can require a lock smith to come out and unlock the trunk to then check and replace the latch unfortunately.
