2000 Lexus RX300 Seat belts Problems

“My son (2.5-year-old, 32lbs) was sitting in his child seat which was on right rear seat. The child seat was secured with lap&shoulder seat belt. While I was driving on a curvy freeway on-ramp at about 25mph, the seat belt unbuckled itself and my son fell with his child seat onto the floor. His head hit the seat back of the driver seat. The speed post on that ramp is 25mph. Actually, this is the 2nd occurrence of the same problem. The first accident happened on 11/20/2010 on another curvy freeway on-ramp. My kids have been sitting on that child seat on the same seat for the past 5 years. …”

The seatbelt has been replaced 2x, but the problem persisted and the dealer was unable to determine the cause of the seatbelt loosening. The factory rep sent out by Lexus also could not find anything the matter. The problem was always intermittent. In late june I rearended 1 possibly 2 cars while going at approx 35mph. …”
