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 **Jaguar XJS** has had its share of common issues. Here are some to be aware of:

1. **Corrosion**: Check for corrosion on all body panels and the floor.
2. **Oil Leaks**: Look out for oil leaks from the rear main oil seal.
3. **Interior Water Leaks**: These can occur through exterior mirrors, clogged drain pipes, and the AC system.
4. **Timing Chain Failure**: Premature timing chain failure can be a concern.
5. **Overheating**: Blocked radiators may lead to overheating.
6. **Head Gasket Issues**: Be aware of head gasket problems across all engines.
7. **Automatic Transmission Mounts**: Keep an eye on these to prevent loosening.

Remember to inspect these areas when considering a Jaguar XJS.
