Front Steering Knuckle Fractures

What NHTSA is examining

The Office of Defects Investigation (ODI) is upgrading its Preliminary Evaluation (PE25006) of front steering knuckle fractures on model year (MY) 2014 through 2017 Range Rover Sport vehicles to an Engineering Analysis. ODI opened PE25006 on June 27, 2025, after receiving 12 Vehicle Owner's Questionnaire (VOQ) reports of the front aluminum steering knuckles fracturing in these vehicles. The reports describe the fractures occurring at the joint where the steering knuckle attaches to the upper control arm ball joint in one or both steering knuckles. Fracture of the front suspension knuckle can lead to detachment of the upper suspension arm. Detachment of the upper suspension arm results in the driver’s inability to control the vehicle, increasing the risk of a crash. ODI reviewed information supplied by Jaguar Land Rover (JLR) in response to Information Request letters as well as reviewed the data with JLR on numerous occasions. ODI further reviewed relevant data on a peer vehicle with a significantly similar steering knuckle design, the MY 2014 through 2017 Range Rover. Much of the information is contradictory and requires a deeper analysis that is available in an Engineering Analysis. On August 5, 2025, Jaguar Land Rover (JLR) filed safety recall 25V514. This recall covers certain MY 2014 and all MY 2015-2017 Range Rover and Range Rover Sport vehicles. The remedy for recall 25V514 addresses knuckles with and without a visible fracture. Knuckles that have developed a visible…
