What’s wrong with it?
IF THE ENGINE SEIZES WHILE THE VEHICLE IS BEING DRIVEN, THE VEHICLE MAY EXPERIENCE SUDDEN DECELERATION LEADING TO AN INCREASED RISK OF A CRASH.
ISUZU IS RECALLING CERTAIN MODEL YEAR 2006-2007 ISUZU NPR, NQR, NRR, GMC W3500, W4500, W5500, AND CHEVROLET W3500, W4500, AND W5500 VEHICLES.
THE OIL PIPE BOLTS WERE NOT TIGHTENED PROPERLY DURING THE VEHICLE PRODUCTION PROCESS.
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, AND THERE MAY BE ABNORMAL ENGINE NOISE AND LOSS OF OIL CAN CAUSE ENGINE SEIZURE.

What the record doesn’t say

- Whether one vehicle or seat has been fixed: only its maker, or NHTSA’s lookup with a VIN, can say.
- This recall names only model years before 2015, which have no pages here. Your VIN, at NHTSA, says which recalls are open on a vehicle.
- How many have been returned or fixed isn’t in the notice.
