Toyota Motor Sales (TMS), U.S.A., Inc., will launch a safety recall with the National Highway Traffic Safety Administration (NHTSA) on certain 2007 model year Tundra four-wheel-drive pickup trucks. The campaign will involve approximately 15,600 units in the U.S. and does not involve any accidents or injures.

On certain 2007 model year Tundra vehicles, there is a possibility that a joint in the rear propeller shaft may have been improperly heat treated, resulting in insufficient hardness. In the worst case, a section of the rear propeller shaft may separate at the joint. There has been one case reported among all affected vehicles that may relate to this condition. The one case involved abnormal noise and did not involve an accident.

Owners will be notified via first class mail beginning in late-December 2007. Owners are requested to contact their local Toyota dealer for inspection upon receiving their notification. If the hardness is not correct, the dealer will replace the rear propeller shaft at no charge to the owner of the vehicle.

Customers with questions or concerns should contact the Toyota Customer Experience Center at 1-800-331-4331.
