Upon picking up my child from daycare today, I inspected her carseat. I found the "superlatch" latch strap was visibly loose. I checked for movement at the belt path and found approx 2" of movement. I immediately tightened it down and checked for movement again. There was no movement. I put my child in her seat and adjusted the harness. I then put my other child in his carseat. Afterwards, I checked the beltpath of my daughter's radian xtsl again. By this point there was abt 0.5" movement (still an acceptable install, but looser than it had been less than 2 minutes earlier). I tightened it down again and drove my children home (abt 4 miles or 10 minutes). Upon arriving home, I noticed that the sl latch strap was visibly loose again. When I checked it at the belt path, there was abt 1.5" movement (more than the 1" of an "acceptable" install). Since I do not know what is causing the loosening, nor how to stop it from happening, I have reinstalled the carseat using my vehicle's seatbelt. I will not risk my child's life by using the seat improperly installed. The carseat is a sunshine kids radian xtsl, model number us 19500 (not available as a choice on the next page of this form) and was manufactured in 10/09. It is installed rear-facing, passenger outboard, in a 2011 VW Jetta sportwagen. (related vehicle information: Model year=2011, make=Volkswagen, model=Jetta sportwagen).
