Wondered if any of you have the same issue. Passenger side rear seat, the part you sit on, you have to flip the plastic handle underneath it to fold it up, same thing lower it. After it working fine for 10 days, it no longer locks in the down position. Also it looks like the seat doesn't quite go down as far as it originally did. Sticks up a tad higher than the middle seat. I can't see anything blocking the seat. This happen to anyone else?
