Toyota Tundra camshafts snapping

Out of a run of 30,000 5.7-liter V8 engines, Toyota has had reports of 20 camshafts snapping — a minuscule number in light of the total (0.06 percent, as a matter of fact). Toyota says the outside supplier of the camshafts has discovered the problem, which was "a metallurgical defect in the casting," and the company is trying to figure out how many of the remaining 30,000 engines could also be affected, though because of the company's production method, the final number is not expected to be large. The camshafts have been designed to prevent collateral damage in case they break, but Toyota will replace a customer's entire engine if the camshaft failure should occur by sending a new 5.7L via airfreight to the nearest dealer. Apparently some Toyota execs believe that the new number one global automaker has been growing too fast to maintain proper quality control. Yet with the Tundra being a new truck with a new engine in a new market for Toyota, there are going to be teething problems, as we've seen. What remains to be seen is if, or for how long, these problems will continue.
