Toyota will inspect - and potentially replace - rusty spare tire carriers in Tacomas sold or currently registered in 21 states or districts.

Toyota's rusty truck woes have been extended to a new recall involving 150,000 2001 through 2004 model year Tacoma compact pickups sold or registered in 20 cold weather states in the Midwestern and Eastern United States.

This latest recall has been issued to correct a spare tire carrier located underneath the pickups' bed. Toyota says that the carrier, which holds the full-size spare tire in place, was not "sufficiently coated with phosphate." Between the limited phosphate and exposure to road salt used in cold weather places, "more than normal corrosion" occurs on the spare tire carrier lift plates.

Some lift plates have broken off entirely, causing the spare tire to separate from the vehicle.

The recall covers Tacomas registered or originally sold in the District of Columbia and Connecticut, Delaware, Illinois, Indiana, Kentucky, Maine, Maryland, Massachusetts, Michigan, Minnesota, New Hampshire, New Jersey, New York, Ohio, Pennsylvania, Rhode Island, Virginia, Vermont, Wisconsin and West Virginia.

Toyota says that owners will be notified by first class mail beginning next month. The recall can be performed at any authorizd Toyota dealer for no charge.

Toyota has previously addressed other rust issues in its Tacoma and Tundra pickups registered or sold in similar places.
