General Motors (NYSE: GM ) made a tremendous effort to ensure that its launch of the all-new Chevy Silverado and GMC Sierra pickups -- GM's most important products -- would go smoothly. All appeared to be going exactly as GM planned -- but now, there are reports that the 5.3-liter V8 engines used in the new pickups may be in short supply.
Sales of GM's pickups were down last month, and Ford (NYSE: F ) was able to gain market-share ground. That's a big problem for GM, but it may not be a GM problem: Bloomberg has reported that the problem lies with a supplier that hasn't been able to keep up with demand.
But as Fool contributor John Rosevear points out, it doesn't matter where the problem lies -- in the face of stiff competition from Ford and Chrysler, GM needs to get it fixed before its new pickup's strong sales momentum stalls.
