Filing in context
This notification is a joint filing by 2 manufacturers: Mitsubishi & UD Trucks.
The Power Steering is the most frequently cited component category in this archive, appearing in 43 of its 4,890 filings. This filing is one of 56 Mitsubishi notifications from 2015 in this archive. For scale, 2,330 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 4 years and 5 months.
Defect
On large touring buses, output variation among power steering oil pumps causes oil temperature to exceed the heat tolerance of the return hose. Continued operation allows the return hose to separate from the power steering oil tank, resulting in an oil leak. As a result, steering effort increases.
Corrective action
For vehicles with 100,000 km or more of travel: inspect the color of the power steering oil tank to assess pump condition. If the pump is determined to be defective, replace the power steering oil pump, tank, and hose assembly with corrected parts. For vehicles registered within one year or with fewer than 100,000 km: because minimal tank discoloration makes pump condition assessment unreliable, replace the power steering oil pump, tank, and hose assembly with corrected parts without performing the color inspection.

状況
大型観光バスにおいて、パワーステアリングオイルポンプの吐出量のバラツキにより、オイルの温度がリターンホースの耐熱温度を超えるものがある。そのため、そのままの状態で使用を続けると、リターンホースがパワーステアリングオイルタンクから外れてオイルが漏れ、操舵力が増大するおそれがある。
改善措置
走行距離が１０万ｋｍ以上の車両は、パワーステアリングオイルタンクの色を点検し、パワーステアリングオイルポンプに問題があると判断された場合は、パワーステアリングオイルポンプ、タンク、ホース一式を対策品に交換する。 また、登録後１年以内または走行距離が１０万ｋｍ未満の車両は、パワーステアリングオイルタンクの色変化が少なくパワーステアリングオイルポンプの良否判断が困難であるため、パワーステアリングオイルタンクの色点検を行わずにパワーステアリングオイルポンプ、タンク、ホース一式を対策品に交換する。
