NHTSA Complaint #11484970 — 2022 TESLA MODEL X

Trying to secure a backless child safety booster seat which has latch tether devices. The Tesla model X 2022 3rd row does not have the latch tether bars. I believe the brand of seat is GoFit Chicco. My 7 year old granddaughter was only restrained with the shoulder lap belt. During a forced rapid deceleration emergency stop she was choked by the seatbelt when the booster seat slid off the seat during rapid deceleration. She was not injured other than a red mark, sorry no photos, and was significantly traumatized from the incident. This booster seat has a clear warning stating the latch system is required and does not have a built in seatbelt channel since it’s backless. The 2nd row seats were in use with two other child safety seats using the latch system which provided ample protection.
