Child Seat Related Problems of the 2009 Honda CR-V

Child Seat problem

I have a sunshine kids juvenile products brand radian xtsl. There have been four occurrences, including today specifically, the latch connector straps have loosened on their own after proper, correct and tight installation through normal use. This poses a great safety hazard to my daughter and this product is a danger when used with latch. This seat is under 1 year old and has been in use for under 1 year, the seat is in good shape, and has never been in an accident. It is installed rear facing and is being used with a child that is 30 lbs and 37 inches tall, well within guidelines for use of latch and for rear facing for this seat according to the manufacturer. There is no reason the latch should be loosening on its own with careful and correct use and installation, and is highly concerning that it would pose this kind of danger. The information off of our seat is as follows: model number: 19500, date of manufacture: 12/2009, date of purchase: March 2010. The actions taken to correct the failure have been to re-tighten the straps, however this is only a temporary solution, as the straps are not correctly retained in a tight or locked position (as seen by the self-loosening action). My concern is that the force of an accident would cause the straps to loosen mid-impact on their own and not restrain a child. (related vehicle information: model year=2009, make=Honda, model=cr-v).
