Overview
| MLIT filing number | 1132250 |
|---|---|
| Type | Statutory Recall (government-mandated recall) |
| Date filed | September 12, 2013 |
| Manufacturer(s) | Nissan |
| Component | Computer (Emissions/Noise) |
| Production period | April 10, 2002 — November 2006 |
| Vehicles affected | 122,080 units |
Defect
The engine control unit software is incorrectly calibrated, causing insufficient intake air volume during deceleration from high engine speeds with the throttle released. This allows unburned fuel to pass through the engine and combust inside the upstream exhaust catalyst, raising the catalyst to excessive temperatures and damaging it. The damaged catalyst generates abnormal noise from debris, and if fragments block the downstream catalyst, acceleration performance deteriorates. In the worst case, the engine may malfunction and stall.
Corrective action
On all vehicles, reprogram the engine control software to the corrected specification. Inspect the catalysts for damage and, if any abnormality is found, replace all four catalysts with new units.

状況
エンジン制御コンピュータのプログラムが不適切なため、エンジン高回転時からのアクセルオフによる減速時にエンジンの吸入空気量が不足することがあり、燃料がエンジン内で燃焼せず排出され、前側の排出ガス浄化触媒で燃焼することで触媒内部が高温になり、触媒が破損することがある。このため、破損した触媒の破片により異音が発生し、また、後側触媒に詰まると加速不良となり、最悪の場合、エンジン不調後にエンストすることがある。
改善措置
全車両、当該エンジン制御プログラムを対策仕様に修正するとともに、触媒の損傷状態を点検し、異常がある場合は触媒（４個）を新品と交換する。
