If your vehicle is showing child seat latch lower anchors are loose, bent, or broken, here are the most likely causes and the parts you'll need to fix each one.
Using excessive force or aftermarket ratcheting devices to tighten child seat straps can permanently bend the metal LATCH anchors over time.
In vehicles where the LATCH anchors are integrated into the rear seat frame rather than the floor pan, loose seat mounting bolts will make the anchors feel loose.
Repeated stress from heavy child seats over many years can cause the factory welds holding the anchors to the body or seat frame to crack and break.
If the vehicle was in a prior accident while a child seat was installed, the crash forces can permanently deform or snap the LATCH anchors.
