WASHINGTON - Isuzu Manufacturing Services of America is recalling nearly 3,000 MY 2006-2007 Isuzu NPR, NQR and NRR vehicles, GMC W3500, W4500 and W5500 vehicles, and Chevrolet W3500, W4500 and W5500 vehicles, according to the National Highway Traffic Safety Administration.
The oil pipe bolts were not tightened properly during the vehicle production process, NHTSA said. If not adequately tightened, the bolt may loosen after prolonged vehicle operation, which can result in oil seepage or leakage from the packing seals.
In general, as oil is lost, the oil warning lamp will illuminate. There may be abnormal engine noise, and loss of oil can cause engine seizure. If the engine seizes while the vehicle is being driven, the vehicle may experience sudden deceleration leading to an increased risk of a crash.
Dealers will replace the packing seals with new ones and the bolt will be tightened with a specified torque. This service will be performed free of charge. The safety recall is expected to begin late January or early February 2011. Owners can reach Isuzu at (800) 255-6727.
