COMMON FAULTS
Please Note: Common Faults in Regularly Used Vehicles vs. Low-Mileage Stored Vehicles that have been used consistently over many years, accumulating approximately 10,000–12,000 miles annually, are more prone to common faults due to regular wear and tear. These issues typically arise from the natural aging of components subjected to frequent use, such as engine parts, suspension systems, brakes, and tires. In contrast, vehicles with low mileage that have been stored or preserved are likely to experience different types of issues. These vehicles are often better maintained to ensure their longevity and may avoid some of the typical wear-and-tear problems seen in regularly driven cars. However, they can still face unique challenges such as degradation of rubber seals, corrosion from prolonged inactivity, or fuel system issues caused by old or stagnant fuel.

The Datsun Sunny 120Y, like many classic cars, has its share of common faults. Here are a few issues that owners often encounter:

1. **Rust**: This is a major concern, especially in the chassis, floor pans, and wheel arches. Regular inspections and rust-proofing can help mitigate this issue Review | Honest John](https://classics.honestjohn.co.uk/reviews/nissan/datsun-sunny-120y-1973/).
2. **Electrical Problems**: Issues with the alternator, battery, and wiring are not uncommon. These can often be traced back to aging components or poor connections.
3. **Carburettor Issues**: The original carburettors can be prone to tuning problems and may require regular adjustments or replacements.
4. **Cooling System**: Overheating can be a problem, especially in warmer climates. Ensuring the radiator and cooling system are in good condition is crucial Review | Honest John](https://classics.honestjohn.co.uk/reviews/nissan/datsun-sunny-120y-1973/).
5. **Suspension Wear**: The suspension components, including bushings and shocks, can wear out over time, leading to a less comfortable ride and handling issues Review | Honest John](https://classics.honestjohn.co.uk/reviews/nissan/datsun-sunny-120y-1973/).

Despite these common faults, the Datsun Sunny 120Y remains a beloved classic for its design and driving experience.
