Bob Single Stroller bottom harness latch broke off when me child was in the seat. (also happened to sister in law double bob stroller) No longer able to utilize 3 point harness properly and stroller not usable. I contacted BOB and since the stroller is out of warranty they offered 30% off a new liner which would include a new harness. I was a bit shocked that they did not offer the liner for free as this was a safety issue and my child could of been severely hurt if the strolled had flipped and the harness tore off. This would have been even worst if we were running with the stroller.
