In April 2005, Mitsubishi filed a statutory recall with Japan's Ministry of Land, Infrastructure, Transport and Tourism (MLIT) concerning the Suspension Arm / Rod. The filing affects 8,041 vehicles manufactured between May 16, 2003 and March 25, 2005.
Overview
| MLIT filing number | 1114150 |
|---|---|
| Type | Statutory Recall (government-mandated recall) |
| Date filed | April 15, 2005 |
| Manufacturer(s) | Mitsubishi |
| Component | Suspension Arm / Rod |
| Production period | May 16, 2003 — March 25, 2005 |
| Vehicles affected | 8,041 units |
Filing in context
The Suspension Arm / Rod is the most frequently cited component category in this archive, appearing in 34 of its 4,890 filings. This filing is one of 140 Mitsubishi notifications from 2005 in this archive. For scale, 1,733 of the 4,890 filings in this archive report a larger number of affected vehicles; the vehicles involved here were manufactured over a span of about 1 year and 10 months.
Defect
On vehicles equipped with a 4-bag air spring suspension system, the ball joint mounting nut securing the V-rod to the rear axle has insufficient clamping strength. Lateral loads during cornering and similar maneuvers cause the nut to loosen. Continued use allows the nut to fall off, separating the V-rod from the axle and degrading directional stability. In the worst case, the axle shifts laterally, causing the tire, wheel, and shock absorber to contact one another. Shock absorber oil may then leak and ignite, resulting in a vehicle fire. (Note: This notification supersedes the recall filed on September 22, 2004 under notification number 1234. The corrective measures from that recall were determined to be insufficient; the remedy content and scope have been revised and are being re-implemented.)
Corrective action
On all vehicles, replace the V-rod assembly with the corrected part and install a cover to prevent separation. Because full supply of the corrected parts requires additional time, an interim measure will be applied: replace the V-rod with a new unit having increased joint fixing nut torque. The corrected part will be installed at a later date.

状況
４バック式空気ばね緩衝装置付車両の後車軸を車枠に固定するＶロッドにおいて、車軸との間のボールジョイント取付けナットの締結強度が不足しているため、車両旋回時等の横荷重により、当該ナットが緩むものがある。そのため、そのままの状態で使用を続けると、当該ナットが脱落し、Ｖロッドと車軸が外れて操縦安定性が損なわれ、最悪の場合、車軸が横方向にずれて、タイヤ、ホイール等とショックアブソーバが接触し、ショックアブソーバのオイルが漏れ引火して、火災に至るおそれがある。 （本届出は、平成１６年９月２２日に届け出たリコール「届出番号１２３４」の対策が不十分であったため、対策内容及び対象範囲を見直し、再度対策を実施するものである。）
改善措置
全車両、Ｖロッド一式を対策品に交換し、離脱防止のためのカバーを装着する。 なお、対策品の全数供給に時間を要するため、当面の暫定措置として、Ｖロッドを新品（ジョイント固定ナットの締付け力を増大したもの）と交換し、後日、対策品と交換する。
