If one of the resistors inside the ECM has a crack on the surface coating, the gas may cause corrosion of the resistor. This could cause the malfunction indicator light to come on, poor drivability (idle instability, poor accelerator), or the engine to stop running during vehicle operation, which could result in a crash.
On certain passenger vehicles equipped with the qg18de engine or qr25de engines, the foam material used for the interior lining of the electronic control module (ECM) box emits sulfur as it cures.
Dealers will remove the inside lining material from the ECM box. Owner notification began on December 22, 2003. Owners should contact Nissan at 1-800-647-7261.
