Child Seat Related Problems of the 2002 Volvo S60

Child Seat problem

My two-year-old son rides rear-facing in his sunshine kids radian xtsl, installed with superlatch and the rear-facing tether. I am a certified child passenger safety technician, so I know the installation was correct. When my son places his foot on the tilt lock mechanism of the superlatch, it significantly loosens it. It loosens it so much that the child restraint moves more than 1" from side-to-side and front/back. He did this while we were driving. When I had initially placed him in his child restraint, there was a tight installation (I always check), but when we arrived at our destination, it was very loose when I took him out. That's when I noticed that how he puts his foot on the tilt lock mechanism. If we had been in a motor vehicle collision during this time, there is a great chance that he could have been seriously injured or died. I immediately contacted sunshine kids via email. Their representative was quick to respond to me and they sent me a replacement superlatch. I have not had any problems with the new superlatch. The representative told me that there have been several reports made about this issue, but that sunshine kids has not been able to "replicate this issue" in their "extensive testing. " she said that the new radians made after February 2011 are equipped with the new updated superlatch. They have added a retainer clip to all tilt lock mechanisms on the superlatch which changes the release angle and prevents any loosening. They also offer the updated tilt lock mechanism to any customer who has a concern about their superlatch. I feel that there should be a recall, because there may be many customers who are unaware of this defect. Even if the installation is correct when you place your child in the child restraint, the loosening can occur, unknowingly, while you are driving and poses serious risk to passengers.
