NHTSA Complaint #11610789 — 2023 RIVIAN R1S

Our son no matter how we try and position him his chin is touching his chest and starts to bubble during our car rides in the mesa max. He also seems to overheat in it and comes out sweaty even with the shortest car ride. We contacted the mfg and they told us he was too big for infant inserts and too small in the bucket itself.. and to wrap a dish towel around the crouch buckle to help keep him push back more. We then met with a company rep who added additional padding in the back of the seat to help position him better. None or these “fixes” really seemed to help in my opinion, as he still screams and bubbles when in this seat.
