Filing in context
This notification is a joint filing by 2 manufacturers: Mitsubishi & UD Trucks.
This filing is one of 56 Mitsubishi notifications from 2014 in this archive. For scale, 2,557 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 3 years and 7 months.
Defect
The heater hoses on large buses have insufficient strength, allowing internal reinforcement threads to break under water pressure. Continued use in this condition causes the hose to fail under water pressure, resulting in coolant leaking. This degrades defroster performance and may prevent the driver from maintaining adequate visibility through the windshield.
Corrective action
On all vehicles, replace the affected heater hoses with corrected parts, and replace the hose clamps from one-touch type clamps to wire-type clamps.

状況
大型バスのヒータホースの強度が不足しているため、水圧によりホース内部の補強糸が切れることがある。そのため、そのままの状態で使用を続けると、ヒータホースが水圧に耐えられず破損して冷却水が漏れ、デフロスタの機能が低下して前面ガラス直前の視野を確保できないおそれがある。
改善措置
全車両、強度が不足している箇所のヒータホースを対策品に交換し、ホースクランプをワンタッチ式クランプからワイヤ式クランプに交換する。
