The big question, then, is what the heck is taking so long? Well, the issues aren't too complicated. First of all, the factories responsible for churning out the repair parts are taking time to ramp up, which GM claims won't be completed until early October. That means that, despite the 400,000 kits that have been produced, the overall supply is still far too low.
As for why it's taking so long to pick up speed, the part's supplier, Delphi, has been forced to pull tooling and equipment out of storage and find new suppliers for the replacement switch's components.
The other big issue is simply getting customers to report in for the repair. A 2012 analysis by the National Highway Traffic Safety Administration showed that over a five-year span, only about 77 percent of owners had recall work completed on their vehicles, a troubling stat if there ever was one.
Considering these factors then, the 154,000 recalled vehicles that GM dealers have sorted out isn't too big of a shock. Here's hoping things get better, and soon.
