Chest Clip, Buckle, Harness Related Problems of the 2013 Subaru Crosstrek

Chest Clip, Buckle, Harness problem

Nuna rava convertible car seat, model cs05107rfd, manufactured 10/15/2021, purchased Jan 2022. Harness failure after completing the remedy for recall 24c-002. Both of my seats had never shown any harness problem before the recall notice. In 2025, I received the remedy kit for both and followed the instructions to clean the harness adjuster and replace the seat pads. The seats worked normally until may 13, 2026, when the harness on one would not lock and the straps would not stay tight. The failed component was the front harness adjuster. I noticed the failure while removing my child after a drive. The harness was loose even though I had tightened it at the start of the drive, and it would not lock when I tightened it again. I recorded a video right after removing my child and the seat from the car. A harness that loosens during a drive cannot properly restrain a child in a crash. No crash occurred and my child was not injured. No one has inspected the seat. I still have the seat and video and can make both available. The harness appears to be working again when I just checked (September 2026). It’s been sitting in our office, unused, since may. I removed the other nuna rava seat from our other car in may after the failure, though it worked normally, and bought two seats from a different brand. I believe the remedy did not adequately fix the original problem. I performed it as directed and the harness still failed. I ask NHTSA to review whether the remedy is adequate and consider expanding the recall to include a replacement or refund for all seats under the original recall.
