BMW is recalling 622,000 SUVs worldwide because the child seat anchors may become damaged and won't hold the seat properly.

The recall covers certain X3 SUVs from the 2011 to 2017 model years, as well as some X4s from 2015 through 2017. It includes nearly 189,000 vehicles in the U.S.

BMW says in documents posted Tuesday by the U.S. National Highway Traffic Safety Administration that the SUVs have anchor bars for child seats that can be damaged when people use European-style child seats. BMW said most child seats in the U.S. have flexible Latch connectors and do not cause the problem.

BMW discovered the problem in March when a customer in Europe reported a damaged anchor.

Dealers will weld a reinforcing bracket to the lower anchor bars at no cost to owners. The recall is expected to start July 12.
