TOYOTA issued a recall on the TUNDRA model

On certain four wheel drive vehicles, the rear driveshaft slip yoke may have received improper heat treatment during the manufacturing process. Insufficient hardness may allow the slip yoke to break, causing the propeller shaft to separate at the joint and come into contact with the road surface or the fuel tank. A fuel leak, in the presence of an ignition source, could result in a vehicle fire. Loss of the rear driveshaft would result in lost propulsion which, in conjunction with traffic and road conditions, and the driver's reactions, could increase the risk of a crash, causing personal injury or death. Correction: Dealers will inspect and, if required, replace the propeller shaft.
