Prevention: Maintain the inverter cooling system in good condition, change the coolant in a timely manner, especially after 100,000 km.

Hybrid Transmission Control System Malfunctions

There may be jerks or delays when switching between hybrid and gasoline engine modes.

Prevention: Regularly update the software at an Infiniti service, as well as diagnose the operation of the transmission and its components.
