Body Hatchback/liftgate Support Device/strut problems of the 2020 Subaru Outback

I have owned the 2020 Subaru Outback since December 2020. Staring in 2021 there have been problems with the lift gate not opening to where it now closes immediately after opening it. This occurs randomly and causes a dangerous situation where one never knows when it will happen. The car has been brought in for service four times over the last four years. Now, that it is out of warranty, and royal Subaru, cortland NY, charged us, two weeks ago, $170 to repair the dysfunctional lift gate. The problem was not fixed. The car was left at last Thursday for the repairing the lift gate which they didn’t fix. Subaru who now want to charge $991 to repair what the dealership was supposed to repair. The work had not been done as yet as it is a manufacturing defect, and a dangerous one at that. This Outback issue is not on my car alone as there have numerous online complaints about a malfunctioning lift gate problem. It’s a law suit waiting to happen as one (family members, grandchildren, friends) may not be aware that the lift gate may close upon their head causing a possible concussion or worse. There needs to be a recall before someone gets seriously hurt.
