INFINITI QX56 performance issues leading to bucking and loss of power during long drives, resolves temporarily with engine restart on INFINITI QX56

Some INFINITI QX56 owners report experiencing performance issues that lead to bucking and loss of power during long drives, which temporarily resolve with an engine restart. These issues may stem from timing chain troubles that can affect engine performance, resulting in rough idling or stalling. Additionally, some owners have reported transmission problems, such as delayed engagement when shifting, which could indicate low transmission fluid or the need for band adjustments. Electrical glitches have also been noted, prompting owners to inspect the fuse box and wiring connections for potential issues. Reliability concerns have been raised, particularly among older models, which may impact performance during extended drives. Furthermore, problems with the catalytic converter and fuel pump failures have been linked to rough idling or stalling, exacerbating performance difficulties. To mitigate these issues, regular maintenance and timely repairs are essential, and consulting with a qualified mechanic or INFINITI specialist is recommended for accurate diagnosis and resolution.
