Isuzu, Chevrolet, and GMC Trucks Recalled for Engine Oil Leak Risk

Plain-English summary

Isuzu Manufacturing Services of America is recalling certain model year 2006-2007 Isuzu NPR, NQR, and NRR, GMC W3500, W4500, and W5500, and Chevrolet W3500, W4500, and W5500 vehicles. The recall involves 2,992 vehicles where the oil pipe bolts were not tightened properly during the production process.

If the bolts are not adequately tightened, they may loosen after prolonged vehicle operation, resulting in oil seepage or leakage from the packing seals. As oil is lost, the oil warning lamp will illuminate, and there may be abnormal engine noise. 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 tighten the bolt with a specified torque at no charge to the owner. The safety recall began on January 28, 2011. Owners may contact Isuzu at 1-800-255-6727 or the NHTSA Vehicle Safety Hotline at 1-888-327-4236.
