I was trying to get my son fitted to the seat before installing it when I discovered the chest plate won't stay latched.

If the chest plate doesn't stay latched, then it's faulty. I would return the seat for another. I had that problem occasionally on the first Boulevard we owned, but this new model seems to have a better design and we've had no trouble.

Contact Britax. They will send you a replacement. Or you can return it to Amazon (if that is where you purchased the seat). Do NOT use the seat without the chest clip fastened. It is required to use the chest clip and it should be at nipple level or armpit level. Also if you child is rear facing, make sure the straps are at or below their shoulders. If the child is forward facing the straps should be above the shoulders. This is very important for the seat's performance in a crash.

I had this problem when I installed. I had to push the dial down and it snapped into place.

I Have a graco car seat and it works fine. It isn't specifically designed for any latch system, but has a safety strap to secure the seat in place.

A wrench is needed to tighten the appropriate bolts holding the seat. Should solve the problem.

Make sure the belt isn't too tight. I put mine together with the the belt as tight as I could get it at first and it squealed. I went back and noticed that the instructions say to keep a little slack in it.

I tried to do the seat reversal myself; there was absolutely no guide, when I ordered, this past summer. I cldn't properly secure it, so my brother, who is an Engineer, had 2be the one to finish the conversion.

Thomas - I just spoke to my son and he says no it won't work. He tried to make it fit but it's not deep enough.

I didn't use the installation instructions because they didn't work for me. I took the top straps and threaded them under the head rests and then fastened them and the bottom straps are supposed to be threaded around the seats. Didn't work for me so I tried to thread them around the seat belts but they pulled the seat belts too tight so I am still trying to figure out how to fasten them. Tried and tried to fold it back up but I couldn't do it even with the instructions so I just leave the barrier up in my car. It isn't in the way and adds 2 extra storage places. It's worked out very well for me since my dog can't go over it and she is finally staying in the back seat!

My seat was purchased in November 2013. I find the chest latch EXTREMELY tight and difficult to unlatch. I also find the strap you pull to tighten the entire harness very hard to get tight enough. These are the only negatives to the seat, but I wouldn't buy it again knowing what I know now. On the other hand, I bought this model because my daughter already had one (for the same child) and she recommended it.

I actually had a Graco car seat and a friend and I tried and tried to get it to fit in the back, but we couldn't make it work.

I just got mine today and have the same problem. The metal hinges won't budge at all and the device won't fit in the cigarette lighter.

How old is your son? The vest is very secure but if he is old enough to unlock the seat belt this won't work.

I had the same problem. After looking through car seat installation guides online, I figured out that for forward facing seats such as this one, the straps for the harness needs to be threaded through AT or ABOVE the child's shoulder. Mine was set a little below, because that's the way we used to do it for the rear facing seats. Once I fixed that (it's now just a tad above my son's shoulder), I have no more problems tightening the harness. If in doubt, contact Britax as they steered me toward the right direction.

Yes my son was new born when we bought it and it's not big enough and the saftey harness isn't secure.
