2017 CADILLAC ESCALADE ESV Structurebody Problems

I WAS RETRIEVING SOMETHING OUT OF THE TRUCK AND THE LIFTGATE FELL ON ME. I NEVER FELT SUCH EXCRUCIATING PAIN. I HAD TO LIFT THE LIFTGATE OFF OF ME. THERE WAS NO WARNING OR ANYTHING THAT GAVE ME THE INDICATION THE LIFTGATE WAS MALFUNCTIONING. WHEN I OPENED THE TRUNK OF THE SUV THERE WAS NO INDICATION SOMETHING LET THIS WOULD HAPPEN BECAUSE IT OPENED JUST FINE. THIS LIFTGATE HIT ME SO HARD THAT IT CAUSED MAJOR BRUISES ON MY BACK AND HIPS. I HURT MY SHOULDER BECAUSE I HAD TO LIFT THE LIFTGATE OFF OF ME. TO SAY THE LEAST I ENDED UP IN THE EMERGENCY ROOM. ME AND MY HUSBAND STARTED SEEING IS THIS AN ONGOING ISSUE WITH THE LIFTGATES AND IT IS. SO MANY COMPLAINTS, YET NO RECALLS. WHAT DOES IT TAKE? SOMEONE TO BE KILLED BY THIS? SO MANY PEOPLE ARE BEING HURT, BUT GM DOES NOT...

I REMOTE STARTED MY VEHICLE TO TAKE MY CAR INTO THE DEALERSHIP FOR SERVICE AND WHEN I WENT OUT TO GET INTO MY VEHICLE THE RUNNING BOARD EXTENDED AND I STEPPED ON TO RUNNING BOARD, RUNNING BOARD IMMEDIATELY STARTED TO RETRACT INTO VEHICLE ALMOST TRAPPING MY FOOT. I TOOK VEHICLE TO DEALERSHIP AND THEY WERE UNABLE TO RECREATE THE ISSUE. ON 10/7/2020 WHEN I WENT TO PICKUP MY CAR THE LOT TECHNICIAN BROUGHT THE VEHICLE AROUND TO THE FRONT FOR ME TO GET IT AND WHEN HE OPENED THE DOOR THE RUNNING BOARDS FOLDED OUT AND THEN ALMOST IMMEDIATELY STARTED TO RETRACT IT COULD HAVE TRAPPED HIS FOOT BETWEEN THE RUNNING BOARD AND CAR TOO. THE DEALERSHIP HAS THE VEHICLE AND IS TRYING TO DETERMINE THE PROBLEM. I HAVE VIDEO EVIDENCE OF THE PROBLEM.
