What Caused the Steering Knuckle Issue?

The steering knuckle issue was caused by a supplier error, where the knuckles were not subjected to a necessary aging furnace step.

This means that the knuckle is not as strong as it should be and is at increased risk of fracture at either the strut or tie rod attachment point if a car hits a pothole or a curb.

The supplier, Bharat Forge Aluminum USA, became aware of the potential fault in late June 2026 during a routine quality audit.
