A recall affects 617 Toyota and Lexus vehicles from the 2026 model year after a batch of front steering knuckles missed an aging-furnace step during production. The incomplete process may leave the forged aluminum parts weaker than intended and more vulnerable to fracturing.

The affected steering knuckles were supplied by Bharat Forge Aluminum USA. The supplier identified the potential problem during a routine quality audit in late June 2026 and notified Toyota. Subsequent testing confirmed that the parts had been installed in vehicles sold in the United States.

Models included in the recall

The Lexus vehicles involved are TX350 models built from June 19 through June 25, 2026; RX350h models produced from June 18 through June 24; RX350 models built over the same period; and TX500h models assembled from June 19 through June 25. One RX500h built on June 23, 2026, is also included.

The Toyota portion of the recall covers Grand Highlander vehicles built between June 19 and June 26, 2026, along with Grand Highlander Hybrid models produced from June 19 through June 25.

Potential loss-of-control risk

Because the affected knuckles may not have reached the intended strength, they could fracture at the strut or tie-rod attachment point if the vehicle strikes a pothole or curb. Such a failure could result in a loss of vehicle control.

No warranty claims, crashes, or injuries related to the steering knuckles had been reported when the recall information was published. Owners are expected to receive notification on November 2.

Dealers will inspect the steering knuckles to determine whether the vehicles contain parts from the affected batch. If a defective component is found, it will be replaced at no cost to the owner.
