A GM supplier simply can't build V8 engine components fast enough.
The Ford F-150 has been the number one-selling pickup truck in the US for decades now, but the new 2014 Chevy Silverado and GMC Sierra are still very popular. Specifically, the 5.3-liter V8 versions, which are selling particularly well. So well in fact, there are reportedly supplier issues due to an inability to keep up with demand. It turns out that a parts supplier, which GM is not naming, is unable to produce enough of the drivetrain components. This shortage could take a couple of months to sort out.
In response, GM has limited the number of V8-engined trucks dealers are able to order. This supplier issue couldn't come at a worse time. One reason is that GM has only a short window until Ford unleashes an all-new redesigned F-150 that will undoubtedly be a formidable competitor. The second concern for GM is that full-size pickups are a huge money maker, with a gross profit of $8,000 to $10,000 per truck. That 5.3-liter V8 made up about 80 percent of the previous generation truck's sales, and this trend is expected to continue with the new model. That is, of course, if GM can figure out a way to resolve this engine shortage in time.
