Start with the model, then the system
This is a guidance hub for Nissan vehicles, not a list of confirmed manufacturing defects across every vehicle of the brand.
Match the reference to your vehicle
Nissan explains that its digital driver guide does not replace the manual supplied with the vehicle. The Sunny name appearing in two markets is not enough to match the transmission or service schedule.

Nissan electrics and sensors
Distinguish the battery from the charging system
Nissan cooling system

Sources and documentation scope
Editorial review: 12 September 2026. A reference for finding owner instructions; we do not use it as fault-frequency statistics.
A background reference does not establish how common a fault is. Match maintenance instructions and equipment to the model year, market and VIN; do not transfer a schedule or specification from a different version.
