The Engine (general) is the most frequently cited component category in this archive, appearing in 12 of its 4,890 filings. This filing is one of 22 Mazda notifications from 2020 in this archive.

Defect
On Ene Charge-equipped vehicles, the crank pulley bolt has an improperly shaped thread root, resulting in insufficient durability. When clamping axial force is low, the crank pulley bolt may fracture, introducing play that prevents accurate detection of crankshaft phase angle. This causes a loss of proper engine control and may result in engine stall.
Corrective action
Replace the crank pulley bolt with a conforming unit on all vehicles. If the pulley or other related components show damage, replace those damaged parts with new units before installing the conforming crank pulley bolt.

状況
エネチャージ仕様車のクランクプーリボルトにおいて、ねじ谷底の形状が不適切なため、耐久性が不足しているものがある。そのため、締付け軸力が低い場合にクランクプーリボルトが折損してガタが生じ、クランクシャフト位相角度を正しく検出できず、適切なエンジン制御ができなくなり、エンストに至るおそれがある。
改善措置
全車両、クランクプーリボルトを良品に交換する。また、プーリ等に損傷がある場合には、損傷のある部品を新品に交換したうえで、クランクプーリボルトを良品に交換する。
