2020 VOLVO XC40 Unknown Or Other Problems

ISSUE1: A FEW WEEKS AGO WHILE MY WIFE HAD STOPPED AT A TRAFFIC LIGHT AND WITHOUT ANY PROVOCATION, HER SEATBELT WENT INTO CRASH MODE, TIGHTENING SIGNIFICANTLY AND LOCKING. THIS WAS TO THE POINT THAT SHE FELT BEING SUFFOCATED FROM PRESSURE ON HER ABDOMEN AND CHEST. FORTUNATELY, THE CAR WAS NOT IN MOTION, OTHERWISE, THE SEATBELT TIGHTENING AND LOCK COULD LEAD TO AN ACCIDENT. THE LOCK RELEASED AFTER 30 SECONDS AND SHE COULD OPEN THE SEAT BELT. SHE HAD CHEST PAIN FOR A FEW DAYS AFTER THIS INCIDENT. ISSUE 2: THREE DAYS AGO WHEN MY WIFE WAS REMOVING GROCERIES FROM THE TRUNK OF THE CAR, AND WHILE THE ENGINE WAS OFF, SUDDENLY THE TRUNK DOOR RELEASED ITSELF AND HIT HER ON THE HEAD WITH FULL FORCE. THIS DOOR IS SUPPOSED TO CLOSE ONLY WHEN A SWITCH INSIDE THE TRUNK IS TRIGGERED OR WHEN THE KEY IS USED TO CLOSE THE TRUNK...
