In the worst case, the stud bolt(s) may fracture, which may result in the separation of the wheel from the hub assembly and lead to a loss of vehicle control.
On certain passenger vehicles equipped with factory aluminum alloy wheels, the lug nut(s) may not secure the wheel properly to the hub assembly due to over-drilling of one or more of the five lug nut holes on the alloy wheel. If the vehicle is driven for an extended period in this condition, the lug nut(s) could potentially loosen.
Dealers will inspect all four factory aluminum alloy wheels and, if necessary, replace any found to be out of specifications. Owner notification began October 27, 2003. Owners should contact Toyota at 1-800-331-4331.
