The seat fabric ripped on my Valco double stroller and I called the company, emailed them pictures and they sent me a new seat. Very nice.
Maeve's car seat, a Britax Decathlon manufactured in 2006, is having issues with the front strap adjuster popping out. It doesn't happen often and doesn't affect the safety of the seat, but it's annoying. I called Britax and since that piece was recalled (they had sent us a piece to "fix" it which apparently didn't work), they are replacing the entire seat for free! It should be here tomorrow.
