In a previous blog, I pointed out some serious problems with the Britax Frontier. I wanted to post a new message to let everyone know that Britax has listened to the complaints and has fixed the problem on new Frontiers. If you have either of the problems previously mentioned, PLEASE call Britax and let them know. I don't know why they have not recalled seats, and I don't know if they will. So you must be proactive to make sure your seat is safe.
Britax added some stiching to the end of the harness to prevent it from coming off the splitter plate. You can NOT add your own stiching to fix it yourself. There is no gaurantee that is safe! Britax will send you a new harness.
