The Chevrolet Blazer is more popular than ever as it enters its third model year. Reborn as a crossover for 2019, today's Blazer may not appeal to fans of the original K5 Blazer SUV, but sales figures continue to be through the roof. And therein lies the problem. Again.

Last September, we reported nationwide Blazer inventory had dipped to a 28-day supply, far from the ideal 60-day vehicle supply automakers typically target. The reason for the low supply was likely due to the combination of high demand and a two-month production stoppage due to the coronavirus pandemic. But now that the Blazer factory in Mexico is back up and running again, you'd assume supply numbers would increase to a more optimal level. Only they haven't.

GM Authority has learned that despite production being mostly back to normal, the Ramos Arizpe Assembly plant simply can't build enough Blazers to meet current demand. There's once again a troubling 28-day supply nationwide. To put this high demand into some greater perspective, a total of 94,599 examples were sold in the US last year, an increase of nearly 63 percent from 2019. The Blazer is now Chevy's best-selling model in America.

In the first half of 2020 alone, Blazer sales were up by an astonishing 183 percent compared to the same period the year prior. Even sales outside of the US, in Canada and Mexico, saw increases. What can General Motors now do to increase nationwide inventory? Unfortunately, not much.

The most obvious solution would be to increase production, but it's far easier said than done. Boosting output involves a variety of factors, such as working with suppliers. One potential solution that was previously mentioned and supposedly hasn't been completely ruled out is to expand Blazer production to another facility, specifically Spring Hill, Tennessee. Ironically, this plant was where GM originally intended to build the Blazer but opted not to so that Spring Hill will sufficient capacity for GMC Acadia and Cadillac XT5 production.

Until a long-term solution is found, Blazer buyers shouldn't be surprised to find some dealers not having their ideal configuration in stock. Or, in the worst case, lacking inventory.
