2017 Subaru Crosstrek Chest Clip Buckle Harness Problems

Your child's car seat harness loosened during normal driving without your knowledge, creating a serious safety risk. There's a known recall for this issue, and Nuna offered you a DIY repair kit instead of replacing the seat—but you don't feel comfortable doing this repair yourself or trusting that it will hold securely in a crash. Other owners have reported that the harness problem continued even after using Nuna's remedy kit, and Nuna has not provided crash test data showing their DIY fix is safe.
