2007 ACURA RDX Child Seat Problems

THIS COMPLAINT IS A FOLLOW-UP TO MY PREVIOUS COMPLAINT, ODI #10394383 REGARDING MY RADIAN 65SL, SERIAL #120900960 03603. DESPITE MY HAVING PROPER INSTALLATION VERIFIED BY SEVERAL CPSTS, THE MANUFACTURER CONTINUES TO INSIST THAT THE ONLY PROBLEM IS THAT I AM NOT TIGHTENING THE BELT ENOUGH. THIS IS NOT THE CASE AS EVIDENCED IN THIS VIDEO: HTTP://WWW.YOUTUBE.COM/WATCH?V=TE4C6YKU8_W THEY HAVE SENT ME TWO REPLACEMENT LATCH BELTS THAT HAVE DONE THE EXACT SAME THING. THE FIRST REPLACEMENT THEY CLAIMED DID NOT WORK BECAUSE "AN INTERN IN THE WAREHOUSE TOOK IT OUT OF A BOX OF DEFECTIVE BELTS." EVENTUALLY, I SENT ALL 3 BELTS BACK FOR "FURTHER TESTING." I WAS INFORMED BY THEIR CUSTOMER SERVICE THAT THERE WAS NOTHING WRONG WITH ANY OF THE BELTS, AND THAT THEY WERE SENDING ME BACK THE ORIGINAL REPLACEMENT TO REINSTALL. UPON REINSTALLATION, IT FUNCTIONS EXACTLY THE SAME -- IT CAN BE LOOSENED BY MY 2.5 YEAR OLD'S...

MY REAR-FACING 2.5 YEAR OLD IS ABLE TO LOOSEN THE TILT-LOCK MECHANISM THAT IS SUPPOSED TO TIGHTEN THE LATCH STRAP ON MY RADIAN 65SL WITH HIS FOOT. HE PRESSES DOWN ON IT WHILE I'M DRIVING AND IT BECOMES LOOSE. I FEEL THAT THIS IS A SAFETY HAZARD. (RELATED VEHICLE INFORMATION: MODEL YEAR=2007, MAKE=RDX, MODEL=ACURA). *TR
