Filing in context
The Fuel pump is the most frequently cited component category in this archive, appearing in 37 of its 4,890 filings. This filing is one of 8 Lexus notifications from 2018 in this archive. For scale, 1,954 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 4 months.
Defect
In the high-pressure fuel pumps mounted on the left and right cylinder banks of the V-type engine, resonance generated as the pumps alternate injection cycles produces greater-than-expected fuel pressure fluctuations. These fluctuations cause the pulsation damper mounting to slide and wear. The resulting damper damage produces abnormal noise and vibration, and continued use may lead to a fuel leak.
Corrective action
On all vehicles, replace the high-pressure fuel pump with the corrected part.

状況
Ｖ型エンジンの左右シリンダバンクに配置された高圧燃料ポンプにおいて、ポンプが交互に噴射する際に発生する共振により、燃圧変動が想定外に大きくなり、パルセーションダンパ（燃圧変動減衰器）の固定部が摺動して摩耗することがある。そのため、当該ダンパが損傷して異音や振動が発生し、そのままの状態で使用を続けると、最悪の場合、燃料漏れに至るおそれがある。
改善措置
全車両、高圧燃料ポンプを対策品と交換する。
