2008 Toyota Sienna Child Seat Problems

THE E-Z-ON ADJUSTABLE VESTS ARE DESIGNED TO BE TETHERED TO THE VEHICLE LATCH SYSTEM AND THE TETHER ATTACHES TO THE VEST RIGHT NEXT TO THE HEAD OF THE CHILD WEARING IT. THERE IS NO WAY AROUND HAVING THE TETHER POSITIONED NEXT TO THE HEAD OF THE CHILD AND IT IS TETHERED WITH A THICK, HARD, HEAVY PIECE OF METAL. WE HAVE ATTEMPTED TO COVER THE HARD METAL WITH THICK FABRIC AND THE HARD METAL IS STILL QUITE CAPABLE OF INJURING THE CHILD WEARING THIS SAFETY SEAT, EVEN WITH PADDING. I AM AMAZED IT IS STILL ON THE MARKET WITH THE CURRENT DESIGN. WE ARE UNABLE TO USE THIS SYSTEM AND WOULD ADVISE OTHERS NOT TO EITHER FOR FEAR OF SIGNIFICANT HEAD TRAUMA FROM THE CHILD SAFETY HARNESS ITSELF. SOME OF THE INFORMATION BELOW IS NOT COMPLETED BECAUSE THIS SAFETY SEAT WAS NOT LISTED IN YOUR DIRECTORY AND BECAUSE THE EXACT PROBLEM IS NOT LISTED ADEQUATELY, EITHER. I CONSIDER THIS SEAT TO BE HIGH RISK FOR ANY CHILD OCCUPANT BECAUSE OF THE VERY OBVIOUSLY LIKELIHOOD OF HEAD TRAUMA! PLEASE LOOK AT THEIR WEBSITE AND HOW THE HARNESS SAFETY SEAT IS SET UP IN THE VEHICLE. IT IS DANGEROUS. I WOULD BE HAPPY TO PROVIDE IMAGES AS WELL OF MY CHILD SITTING WITHIN THE HARNESS. WE WERE NOT ABLE TO USE THIS DEVICE AT ALL DUE TO THIS SAFETY RISK. (RELATED VEHICLE INFORMATION: MODEL YEAR=2008, MAKE=TOYOTA, MODEL=SIENNA). *TR

I HAVE A RADIAN XTSL CAR SEAT THAT WILL NOT STAY TIGHTLY INSTALLED IN MY 2008 TOYOTA SIENNA WHEN INSTALLED WITH LATCH IN EITHER THE FF OR RF POSITION. I INSTALL IT CORRECTLY, BUT DUE TO THE ANGLE THE LOOSENING MECEHANISM HITS THE SEAT IT CONTINUALLY BECOMES LOOSE. I NOTICED THIS WHEN I PULLED ON THE STRAP TO TIGHTEN THE HARNESS AND THE ENTIRE SEAT LIFTED OFF MY VEHICLE SEAT. (RELATED VEHICLE INFORMATION: MODEL YEAR=2008, MAKE=TOYOTA, MODEL=SIENNA)
