I shouldn’t be surprised, but I was when our second car seat buckle broke as I snapped in my daughter. Evidently the Sunshine Kids Radian car seats with the black chest harness buckle was not designed for cold weather. This winter has not been the most cold winter since we bought the seats, but evidently it was cold enough compounding any weakness the buckles received over the years.
Hopefully, the service representative will be as helpful as last time in supplying the replacement parts. Knowing the process, I have all the required info at hand and ready to go.
