What's wrong?
On these 2013-2016 Mazda CX-9, MAZDA2, CX-5, and CX-3 vehicles, the front strut assembly connects to the steering knuckle with lower mounting nuts and bolts. The strut helps support the front suspension, while the steering knuckle holds the wheel hub and turns with the steering system. That bolted joint has to stay tight so the wheel, strut, and steering parts stay aligned.
Mazda traced NHTSA campaign 16V203 to automated fastening equipment at the factory. Under certain tightening checks, the system did not tighten those lower mounting nuts and bolts to the required torque. When the joint starts loose, normal road vibration can loosen it further, allowing the steering knuckle to separate from the front strut assembly.
There is no warning sign before failure. A front-end noise was found during Mazda's investigation, but the recall does not identify a reliable owner warning that appears before the joint comes apart.

What happens at the repair
At the dealer, a Mazda technician inspects the lower mounting nuts and bolts that secure the front strut assembly to the steering knuckle. If the inspection finds loose bolts, the technician replaces them and tightens the hardware to the correct specification. The recall repair is available through Mazda dealers, and the replacement parts and labor are covered by the recall.
