I AM WRITING IN REGARD TO A FULL SIZED FAMILY VEHICLE THAT I LEASED IN 2006. I LEASED A 3 ROW 2006 ENVOY DENALI XL BY GM. I ALREADY HAD A 14 YEAR OLD SON AND DID NOT THINK I WAS ABLE TO HAVE MORE CHILDREN. HOWEVER, I HAPPILY DISCOVERED THAT MY HUSBAND AND I WERE EXPECTING IN MARCH OF 2007. THE ISSUE WITH MY VEHICLE IS THAT IT DOES NOT HAVE THE LATCH SYSTEM AVAILABLE IN THE CENTER OF THE SECOND ROW, WHICH IS WHERE I BELIEVE THE CARSEAT IS SAFEST. IRONICALLY, MY HUSBAND HAS A 2000 GMC EXTENDED CAB WHICH HAS THE LATCH SYSTEM IN ALL THREE SEATS OF THE 1/2 SECOND ROW. I HAVE CONTACTED THE DEALERSHIP, GM DIRECTLY, ETC. NO ONE HAS A SOLUTION TO THIS ISSUE. MY ARGUMENT IS THAT IF IN A CASH WITH THE CURRENT VEHICLE SPECS, THE SIDE AIRBAGS COULD DEPLOY, THUS HARMING MY DAUGHTER IN THE SIDE POSITION. HOWEVER, I BELIEVE THIS LACK OF THE LATCH SYSTEM IN THE CENTER IS AN OBVIOUS DEFECT THAT SHOULD BE CORRECTED. I WOULD APPRECIATE ANY SUPPORT YOU COULD PROVIDE. *TR
