NHTSA Service Bulletin 10214879: 2022 Isuzu N-series
Official manufacturer communication context for 2022 Isuzu N-series, with affected products, buyer checks and links into Carchieve recall, problem and VIN research.
Reviewed June 2026 from NHTSA manufacturer communication and service bulletin records. Carchieve is independent and not affiliated with any vehicle manufacturer or government agency.
Isuzu Motors Limited has decided that a defect exists in certain 2022 model year Isuzu NQR and NRR trucks (equipped with 6.0L gasoline engines) built before November 3, 2021. In the affected vehicles, the engine wiring harness assembly was incorrectly wired at the pinout connector for the oil pressure sensor. The ECM (and a technician's scan tool) will not detect the condition for low oil pressure and will always perceive the pressure to be at 126 PSI. If the oil pressure drops below a certain level, the engine oil pressure telltale will not illuminate to indicate low pressure. If the engine oil pressure is low, the defect will mask the warning to the driver or consumer, who may continue to operate the vehicles with a low engine oil pressure. If the engine continues to operate at a low engine oil pressure, it could damage the engine or its components and could cause the engine to seize and stall without prior warning. A seized engine can result in vehicle stalling and increase the risk of crash.
What this bulletin may mean before buying
Treat this as service research, not a verdict on one car. Before you buy, compare this communication with official recall campaigns, model-level owner complaint patterns, and the exact vehicle’s VIN-decoded specifications. A bulletin can help you ask a seller or dealer sharper questions about software updates, known repairs, warranty extensions and service history.
