Subaru WRX STI Engine Reliability

The Subaru WRX STI is a performance-oriented version of the Subaru Impreza, and it has been renowned for its impressive performance and all-wheel-drive capabilities. However, one question that often arises when it comes to Subaru WRX STIs is whether or not they blow up often.

The short answer is no, Subaru WRX STIs do not blow up often. While there have been reports of engine failures in some Subaru WRX STIs, these instances are relatively rare and are often the result of neglect, modifications, or aggressive driving habits.

Common Causes of Subaru WRX STI Engine Failure

  1. Lack of Maintenance:
    The most common cause of engine failure in Subaru WRX STIs is a lack of proper maintenance, particularly oil changes. Over time, oil can break down and lose its lubrication properties, which can lead to increased wear and tear on the engine components. Eventually, this can cause the engine to fail. It is essential to follow the manufacturer’s recommendations for oil changes and other routine maintenance tasks to ensure your engine remains in good condition.

  2. Modifications:
    Modifying your Subaru WRX STI can significantly impact engine reliability. While modifications can increase performance, they can also put added stress on the engine components, which can cause premature failure. It’s important to research any modifications you are considering and consult with a professional mechanic to determine if they are safe for your engine.

  3. Aggressive Driving:
    Subaru WRX STIs are designed for performance, but aggressive driving habits can take a toll on the engine. Rapid acceleration, hard braking, and high-speed driving can cause excessive wear and tear on the engine components, leading to premature failure. It’s important to drive responsibly and avoid pushing your engine to its limits regularly.

  4. Poor Tuning:
    If your Subaru WRX STI is not tuned correctly, it can cause significant damage to the engine. Poor tuning can cause the engine to run too lean or too rich, which can cause excessive wear and tear on the engine components. It’s essential to have your Subaru WRX STI tuned by a professional mechanic to ensure that it is running correctly.
