I own a 2018 Lexus NX F Sport and have had repeated fuel pump failures since purchasing the vehicle in October 2022. We have replaced the fuel pump twice — once at the dealership where we bought it and again less than a year ago. Despite these repairs, the same issue continues to occur.

Foam is breaking off of the shell. Reached out to Chicco and issue was not resolved nor replaced. This seems to be a reoccurring problem with this car seat.
