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 **Reliant Robin (1973-82)** had its fair share of quirks and common faults, some of which became legendary among owners. Here are a few key issues:
- **Handling Instability** – As a **three-wheeler**, the Robin was prone to **tipping over** if cornered too aggressively.
- **Fiberglass Body Issues** – The **gel coat** could suffer from **crazing, cracking, and fading** over time.
- **Chassis Rust** – The **steel frame** was vulnerable to **corrosion**, especially around the **suspension mounts**.
- **Weak Brakes** – The **drum brakes** lacked stopping power compared to modern systems.
- **Electrical Problems** – Wiring could degrade, leading to **faulty gauges, poor earthing, and intermittent lighting issues**.
- **Cooling System Issues** – Overheating could occur due to **blocked radiators or failing water pumps**.
- **Engine Wear** – The **848cc OHV engine** was reliable but could suffer from **oil leaks and excessive smoke**.
Despite these faults, the **Robin** remains a **quirky and beloved classic**, with a strong enthusiast community keeping them on the road.
