The bolts may become loose during operation a could detach completely. The detached bolts could damage rear brake components resulting in reduced braking an a potential wheel lockup.
Owners will be notified to return to their Toyota dealer to have the rear axle hub bearing bolts inspected. If a bolt is found to be loose, the dealer will re-tighten them with the specified tightening torque. If a bolt is detached, the dealer will replace the rear axle hub bearing assembly and rear brake components with new ones.
