Suspension Coil Spring - Repair or Replace
Your coil springs are not especially prone to failure, but if they have been cut, clamped, or heated to have the vehicle lowered, your 2015 Mazda 6 might benefit from replacing the strut springs. Excessive rust can make the springs more prone to failure. Contact your local Mazda service department to have your suspension system evaluated.
