What this recall means for you

On certain vehicles, one of the six brake caliper mounting bolts on the driver-side steer axle may have been incorrectly tightened. The loose bolt can cause the other caliper bolts to loosen as well. Insufficiently tightened bolts may not provide adequate clamping force between the brake caliper and the brake anchor plate, which can reduce brake effectiveness and increase the risk of a crash.
