2002 Ford Escape Child Seat Problems

CONCERN THAT ONLY ONE CONNECTOR STRAP LOCKS ON GRACO AFFX BOOSTER SEAT AFTER CONNECTOR CLIPS ARE ATTACHED TO LATCH BRACKETS. OTHER ONE DOES NOT LOCK IN SO SEAT CAN BE PULLED OUT ON ONE SIDE. CALLED GRACO A BIT AGO AND THEY SAID THIS IS "NORMAL" AND NOT A DESIGN FLAW. HOWEVER, INSTRUCTIONS SUGGEST PULLING ON STRAPS WILL HOLD SEAT IN TIGHT UNTIL RELEASE BUTTON IS PUSHED. I AM READING SIMILAR COMPLAINTS IN ON-LINE REVIEWS AS WELL AS OTHERS WHO SAY THIS IS NOT A PROBLEM....WHICH SOUNDS LIKE IT IS A PROBLEM!. BOTTOM LINE: WITH ONE SIDE OF THIS SEAT NOT LOCKING TIGHT LIKE THE OTHER SIDE AND ABLE TO SLIDE LOOSE FROM FLUSH AGAINST THE BACK OF THE VEHICLE SEAT, IS THIS BOOSTER SEAT SAFE FOR MY CHILD TO USE, I.E., DOES IT RETAIN ALL ITS APPROVED CRASH SAFETY FEATURES WHETHER THE SEAT IS LOCKED IN TIGHT (AS SOME USERS APPEAR TO BE ABLE TO DO) OR SLIDES LOOSE ON ONE SIDE WITH SLIGHT PULLING, SUCH AS MAY OCCUR IN THE EVENT OF AN IMPACT?? NOTE: COULDN'T FIND DESCRIPTION OF BOOSTER IN DROPDOWN LIST FURTHER ON. IS GRACO AFFIX BOOSTER, MODEL 1839168 (RELATED VEHICLE INFORMATION: MODEL YEAR=2002, MAKE=FORD, MODEL=ESCAPE). *TR

HAVE NOTICED ON MORE THAN ONE OCCASION THAT THE SUPERLATCH ON OUR XTSL IS LOOSENING TO A VERY UNSAFE LEVEL. IT IS INSTALLED FORWARD-FACING AND CHILD DOES NOT TOUCH THAT PART OF THE SEAT GETTING IN OR OUT. WHEN I'VE CHECKED THE SECURITY OF THE SEAT, IT WILL WOBBLE AT THE BOTTOM BACK & FORTH BY 3-5 INCHES. TIGHTENING IT ONLY FIXES IT TEMPORARILY SO IT IS NOT AN INSTALLATION PROBLEM, IT IS A FAILURE OF THE SUPERLATCH. I'M VERY CONCERNED ABOUT MY CHILD'S SAFETY IN THE EVENT OF A CAR ACCIDENT. I WILL BE SWITCHING THE SEAT BACK TO OUR OTHER CAR, A 2010 FUSION SEL AS I DID NOT NOTICE IT IN THAT CAR, BUT I WILL BE MONITORING IT VERY CLOSELY.
