NHTSA Complaint #10691298 — 2002 MERCURY SABLE

I PURCHASED THE GRACO COMFORT SPORT CONVERTIBLE CAR SEAT FOR MY 8 MONTH OLD. APPEARS TO BE A GREAT SEAT UNTIL YOU TRY TO INSTALL IT TO A VEHICLE. I HAVE TRIED PUTTING INTO TWO DIFFERENT CARS, I HAVE TRIED USING THE LATCH SYSTEM AND THEN TRIED THE REGULAR SEAT BELT, NO MATTER WHAT I DO THE SEAT FLOPS AROUND THE BACKSEAT LIKE A DEAD FISH. THE PART WHERE THE TETHER STRAP GOES THROUGH IS AS TIGHT AS IT CAN GET AND THE TOP OF THE CAR SEAT STILL MOVES 5-10 INCHES SIDE TO SIDE. SEVERAL PEOPLE HAVE TRIED TO INSTALL THIS SEAT AND NONE HAVE BEEN SUCCESSFUL. THIS SEAT NEEDS TO BE RECALLED. (RELATED VEHICLE INFORMATION: MODEL YEAR=2002, MAKE=MERCURY, MODEL=SABLE). *TR
