ISUZU issued a recall on the NPR-HD, NQR, and NRR models

On certain vehicles equipped with an oil pan heater, over time, dust, dirt and moisture may collect at the contact point between the oil pan heater cord and the extension cord. As a result, the extension cord could overheat, which may melt the oil pan heater plug and/or block heater plug (if equipped). This could result in a fire causing property damage and/or personal injury. Correction: Dealers will inspect and clean the oil pan heater plug and the engine block heater plug (if equipped). Heat damaged plugs will be replaced. In addition, dealers will replace the extension cord and advise owners to store the cord indoors when not in use.
