Rising diesel fuel prices have pushed costs to near record highs, creating significant challenges for truck dealers as heavy-duty vehicle inventories grow. Analysts warn that the economic strain could lead to a modest decline in light-vehicle sales during the upcoming quarter. The surge in fuel expenses is adding pressure to an already strained supply chain, raising concerns about consumer demand. Industry observers are closely watching how these trends may reshape the automotive market in the near term.


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.
