The lower anchor strap on my son's sunshine kids radian xtsl spontaneously loosened with no pressure on the release button or locking device. As a cpst, I check the installation daily, so I know this had been a rock solid installation and the locking device was properly aligned on the shell of the seat (not in or on the edge of the beltpath), prior to the strap spontaneously loosening.

Super latch strap continually loosens. Seat has been installed by cpst and when barely touched, the adjuster buckle loosed to a very dangerous point. Seat became extremely mobile while latch was still connected. I have two radian xtsl seats. One child is barely 20lbs, and the other is 35lbs.
