“Insufficiently torqued bolts may not provide adequate clamping force between the brake caliper and brake anchor plate potentially resulting in reduced brake effectiveness. Reduced brake effectiveness could lead to a vehicle crash,” the reports indicated.
The report describes the issue as, “Vehicles manufactured with a certain steering arm configuration with air disc brakes might have one of the six brake caliper-mounting bolts on the driver side steer axle incorrectly torqued. This could result in surrounding caliper bolts to loosen.”
To remedy the issue, franchised DTNA dealers will inspect and, if necessary, repair the problem. Dealers will be notified of the recall beginning March 19 with customer notification to follow.
