    my son is rear facing and puts his arm in the forward facing belt path then can not get his arm back out. he starts screaming and crying and i have to pull the car over to the side of the road to help him get his arm out and even i struggle getting his arm free. no sooner than i start driving again, he puts his arm back through and it’s the same cycle. i have contacted britax and have unfortunately not gotten any solution for this issue.

    We were driving on the freeway when my son started screaming to a point we had to get over and stop to check what was going on. His arm got stuck in the forward facing belt path and he couldn’t get it out. I had to get him completely unbuckled in order to take him out of the seat sideways as otherwise I would have pulled the arm out at the shoulder.

    No idea. Noticed the car seat was wobbly and then saw a huge crack in the shell.

    The tension release at the bottom of the harness (the switch that's depressed to release tension so the harness can be tightened/loosened while putting the child in it) has a screw holding it to the shell of the seat. This screw backs out over time. There does not appear to be a nut or thread locker used to secure the screw against backing out. The threads do not appear to be stripped upon inspection and the screw goes back into its original hole. When tensioning the harness to secure my child into the seat, the entire tensioner separated from the seat. This is the second time we've had this happen with this car seat model. Each instance has happened on a different seat but the failure is the same.

    It is extremely difficult to tighten the harness on this seat. As we have used the seat more, the harness has gotten nearly impossible to get snug enough to be safe. I am a CPST, so I am sure the seat was adjusted properly for my child. I also talked to a CPST at Britax to make sure I wasn’t missing something that could help. I was sent a new harness to see if it would help, but it did not make any difference. We have since stopped using this car seat and replaced it.
