Overview
| MLIT filing number | 1131263 |
|---|---|
| Type | Statutory Recall (government-mandated recall) |
| Date filed | March 28, 2013 |
| Manufacturer(s) | Isuzu |
| Component | Exhaust pipe |
| Production period | August 27, 2007 — June 20, 2011 |
| Vehicles affected | 504 units |
Defect
On medium-duty trucks, the exhaust pipe structure is inadequate. Engine resonance and repeated thermal cycling impose excessive stress on the exhaust pipe, causing cracks to develop in the exhaust pipe, exhaust pipe brackets, and clamps. If the vehicle continues to be operated in this condition, in the worst case, noise levels may increase significantly. Interim measure: If abnormal noise or other irregularities are detected from the exhaust pipe area, inspect the affected components. If cracks are confirmed, replace or repair the affected parts. Permanent remedy schedule (planned) — Phase 2, January 2014: ③ 2007–2009 model year FRS90, FSS90.
Corrective action
On affected vehicles, the exhaust pipe, exhaust pipe brackets, and clamps will be replaced with corrected/revised parts. Because procurement of corrected parts requires time and the location of the defect varies by vehicle model, permanent repairs will be prioritized for vehicles with the highest incidence of the defect.

状況
中型トラックにおいて、排気管の構造が不適切なため、エンジン回転による共振、および冷熱の繰り返しにより排気管に過大な入力が発生し、排気管、排気管ブラケット、クランプ等に亀裂が生じることがある。そのため、そのままの状態で使用を続けると、最悪の場合、騒音が増大するおそれがある。
改善措置
車両、排気管、排気管ブラケット、クランプを対策品に交換する。尚、対策部品の準備に時間を要し、車両型式毎に不具合発生箇所が異なるため、不具合件数の多いものから恒久対策を行う。 暫定対策；排気管周辺より異音等が発生している等、異常を感じた場合には点検を行い、不具合部位に亀裂が確認された場合は、新品に交換または修理を行う。 恒久対策開始時期（予定） 第２段 ２０１４年１月～ ③２００７－２００９年式 ＦＲＳ９０，ＦＳＳ９０
