So I got my son out of his booster today and the left rear seatbelt wouldn't retract. Once I got home I took the rim off an got it to retract but compared to the other side it's sluggish and doesn't want to retract right. It already seems odd that you have to retract the rear seatbelts all the way to get the locking feature unlocked, but now it won't retract right. Anyone ever run into this? I guess I can add it to the list for the next CPO trip to the stealer.
