2020 Subaru WRX Brakes Problems

UPON APPLYING PARKING BRAKE TO THE MAXIMUM EXTENT POSSIBLE, WHICH IS BEYOND 11 CLICKS AS STATED AS REQUIRED BY SUBARU, AND THE VEHICLE IS ON AN INCLINE GREATER THAN 8 DEGREES, THE VEHICLE WILL NOT REMAIN IN PLACE. I AM ALSO CONCERNED THAT IF THE BRAKE IS REQUIRED IN AN EMERGENCY SITUATION, IT WILL NOT EFFECTIVELY STOP THE VEHICLE AS THE WHEELS ARE STILL ALLOWED TO TURN MORE FREELY THAN EXPECTED GIVEN ITS INABILITY TO HOLD THE VEHICLE ON A HILL. I TOOK THE VEHICLE TO SUBARU TWICE EXPRESSING THE COMPLAINT AND WAS SUMMARILY DENIED SERVICE. THE TECHNICIAN REFUSED TO EVEN INSPECT VEHICLE EVEN AFTER REQUESTING AN INSPECTION. THE SERVICE TECHNICIAN INFORMED ME THAT YOU MUST APPLY THE PARKING BRAKE TO 11 CLICKS AND PUT THE VEHICLE IN GEAR. THE FORCE REQUIRED TO PULL THE PARKING BRAKE TO 11 CLICKS IS MORE THAN MANY PEOPLE ARE ABLE TO APPLY IN A SINGLE MOTION AS REQUIRED BY FEDERAL LAW. IN ADDITION, AIR COMPRESSION IS EXPLICATED STATED IN FEDERAL LAW AS NOT ALLOWED AS A MECHANISM OF FORCE FOR USE IN A PARKING BRAKE SYSTEM. AIR COMPRESSION IS WHAT IS USED IN THE ENGINE AS A MEANS TO PREVENT THE WHEELS FROM MOVING WHEN IN GEAR. FURTHER, THE PARKING BRAKE SYSTEM SHALL ACCORDING TO FEDERAL LAW, USE AN ACCUMULATION OF FORCE INDEPENDENT OF OTHER SYSTEMS FOR THE PARKING BRAKE, WHICH IS NOT THE CASE PER THE INSTRUCTION FROM SUBARU. LASTLY, SUBARU ALSO INSTRUCTED ME TO PUT A WHEEL STOP BEHIND THE WHEEL AS A STANDARD PRACTICE IN THIS COMMON PARKING SCENARIO, WHICH ISN'T POSSIBLE TO DO IF I HAVE TO TAKE MY FOOT OFF THE BRAKE TO GET OUT OF THE CAR TO PLACE THE WHEEL STOP. AS SOON AS I TAKE MY FOOT OFF THE BRAKE, THE VEHICLE MOVES SO I AM UNABLE TO SAFELY EXIT VEHICLE IN ORDER TO PLACE THE WHEEL STOP. THIS IS A SERIOUS SAFETY ISSUE BOTH FOR KEEPING A PARKED VEHICLE IN PLACE AND ALSO IN AN EMERGENCY BRAKE SCENARIO.
