I own two sunshine kids superlatch radians (65sl) [model: US16500, dom 12/09, serial # 12090124403603]. I have installed them both rear facing and forward facing in my 2007 Toyota Sienna with latch. Initially, the installs appear to be tight and not move more than 1 inch in any direction. The latch strap on both car seats "self" loosen while the child rides in the seat. I am able to replicate the issue with every use regardless if seat is rear facing or forward facing. I have contacted sunshine kids to report the problem and was not given a solution to my complaint. I am currently certified as a child passenger safety technician. My fear is, the seat appears to be correctly installed and compatible with the vehicle but then it becomes compromised during/after use. Issue: Adjustment buckle on the latch strap loosens over time.
