Rising diesel fuel prices have pushed costs to near record highs, creating a surge in unsold heavy-duty trucks that is straining dealerships across the industry. Analysts warn that the economic pressure could lead to a modest decline in light-vehicle sales during the third quarter as consumer spending tightens. The combination of soaring fuel expenses and a growing inventory backlog raises concerns about dealer profitability and market stability. With demand potentially cooling, automakers and retailers may face tougher decisions about pricing and promotions.
With diesel gasoline nearing $6.51 a gallon on average, swelling heavy-duty truck inventory is rattling dealers. Third-quarter light-vehicle sales are expected to fall slightly, forecasters say.
