Frontiers were first sold here in December 2013. They were dated October 2013 and it seems models dated from this time to mid 2014 may see a poor fitting seat belt when used in booster mode. Changes have been made to the later model Frontier seats, as they have re-sculpted the armrests/belt guide at the hips.
We’re not sure when the new models will be sold here, or if they already are, but I know that most of us have the affected model, and the seat does not come with the clip mentioned below.
There is a solution for this, please contact Britax USA with your car seat model name, and serial number – asking for a Secure Guard Clip – part number S922000.
Ours came directly from the US, at no cost to us. We tried to contact Britax NZ for this, however were only communicated with once, and they tried to sell us the clip:
“The Secure Guard is in our next container from Britax USA due late March early April the cost is $19.99NZD each includes GST.”

Britax USA stated:
“The consumer would need to contact us directly. We would only be sending out Secure Guard, because that will resolve their issue if they happen to have a fit issue.
Needless to say, our clip from the US came before the date stated above, and not a cent was exchanged.

And have your car seat details handy, you need your serial number, DOM and seat details as well as giving them your address.
The clip helps to keep the lap portion low down on the bony hip part of the pelvis and prevents the belt from creeping up toward the soft abdomen. It sits in the buckle slot of the seat when used in booster mode and comes with fitting instructions.
Car Seat Blog states “For many kids, there was no issue at all. For some, especially smaller kids in certain vehicles, the booster fit was not as good as it could be.”
The image below shows the lap belt sitting too high [affected models] – the secure guard keeps the lap belt down low, over the upper thigh, rather than over the lower abdomen.
