NHTSA recall 19V132000

What's wrong: An incorrect rear seat back covering carpet could have been installed on the split-rear seat back. As a result, the child seat anchorage point (top tether) on the center positon of the rear seat may be covered and inaccessible for use. As such, these vehicles fail to comply to federal motor safety standard (fmvss) number 225, "child restraint anchorage systems."

Why it matters: If the upper anchorage point is covered, the child seat will not be able to be secured as intended in the center position of the rear seat, increasing the risk of injury in the event of a crash.

The fix: Mercedes will notify owners, and dealers will check the rear seat back covering carpet on the affected vehicles and replace it if necessary, free of charge. The recall began April 6, 2019.
