Bought a britax marathon xe E9lr31A batch: Job0005290 manufactured 03/2014. I attached the car seat per the directions on the manual (rear facing) to the rear captain seat of my 2008 Toyota Sequoia. I used the versa tether located on the rear of the car seat to make the car seat more secure and secured the remaining portion with the tether. The remaining tether portion eventually became loose and unknowingly became lodged in the right rear door with the end sticking outside of the door. While driving on a city street I heard a sound from the right rear of the vehicle and immediately pulled over at which time the tether got caught underneath the right rear tire and pulled the car seat (with my son in it) towards the door and almost physically hurt my son and almost damaged the captain seat of my vehicle. Fortunately my son was only scared by the situation and no physical harm was done to him. The captain seat of the vehicle was saved by the seat protector that has an extreme indention on it from the force that was applied by the wheel catching the tether. There are also marks in the paint and scratches on the lower end of the right rear door where the tether was lodged. The versa tether on the rear of the seat is dangerously long and I would suggest some sort of feature to reduce the length with something besides the elastic strap or provide separate sizes.
