2002 LEXUS LS430 Structureframe And Members Problems

THE TRUNK LID OF MY 2002 LEXUS LS 430 HAS TWO PNEUMATIC STRUTS WHICH PROVIDE LIFT AND KEEP THE LID UP IN THE OPEN POSITION. NOW, OVER TIME THE STRUTS SLOWLY FAILED TO KEEP THE TRUNK LID OPEN, AND IN A GENTLE BREEZE, THE LID WILL COME DOWN WITH GUILLOTINE FORCE. IT HAS HIT MY HEAD SEVERAL TIMES WITH PAINFUL RESULTS AND NOW I AM AFRAID TO LOAD ITEMS IN MY TRUNK WITHOUT ANOTHER PERSON THERE TO HOLD IT OPEN. I THINK THAT THE "LIFT ASSIST" OF THE PNEUMATICS SHOULD BE ONLY AUXILIARY TO A MECHANISM THAT HOLDS THE TRUNK IN A FULL OPEN POSITION. I HAVE NEVER HAD A VEHICLE WHOSE TRUNK LID DID NOT STAY IN THE OPEN POSITION ONCE LIFTED, REGARDLESS OF AGE. *TR

ON DEC. 27, 2009 ,FULLY OPENED THE TRUNK LID OF MY LS430 & WITHIN SECONDS IT CRASHED DOWN ON MY NECK AS I WAS LEANING IN TO GET SOMETHING. THOUGHT IT WAS JUST A FLUKE. AGAIN ON MARCH 3,2010, IT HAPPENED AGAIN , HITTING ME ON MY HEAD. THE 3RD TIME WAS ON MEMORIAL DAY, MAY 31, 2010, AGAIN ON MY HEAD. NOW I WILL ONLY OPEN MY TRUNK LID WHEN SOMEONE ELSE IS PRESENT TO HOLD IT OPEN FOR ME SO IT WON'T FALL ON ME AGAIN. *TR
