NHTSA Complaint #11632013 — 2017 FORD ESCAPE

The Nuna Revv we own is a rotating convertible car seat. When we first installed the car seat, we heard metallic rattling from inside the car seat and base when driving. I went to inspect the car seat and found excessive movement between the car seat and the base. This motion is well over a quarter inch of travel in all directions regardless if the car seat is in the locked or unlocked position. This movement appears to be a safety concern and I do not trust this car seat to safely restrain my child in the event of a crash. We contacted the manufacturer about our concerns and they said some movement is expected but did not quantify how much movement is acceptable between the car seat and the base. The manufacturer offered to send replacement parts, but this car seat and base are not made to be detached from each other and I find it concerning that the manufacturer expects a customer to disassemble the internals of car seat. There are also no instructions on how to remove the base in the car seat user manual. No one has inspected the car seat in person.
