If you’re a car enthusiast and high-performance cars are your jam, then you have probably heard of the Subaru STI. This car has been in production since 1992 and has been a fan favorite among car enthusiasts. However, the reliability of the Subaru STI is a common concern among potential buyers and current owners.
In this article, we will discuss the reliability of the Subaru STI, common issues that owners may face, best practices for maintaining these cars, and any updates or changes made to newer models that improve reliability.
Subaru STI Reliability
The reliability of the Subaru STI is a topic of debate among car enthusiasts. The STI is a high-performance car that is meant to be driven hard, and hard driving can put a lot of strain on any car. However, Subaru has a reputation for building reliable cars, and the STI is no exception.
According to J.D. Power’s Vehicle Dependability Study, the 2019 Subaru WRX (which shares the same platform as the STI) ranked second in the Compact Car category for dependability. This ranking is based on the number of problems reported per 100 vehicles.
In terms of repairs, the STI does not have any major issues that are common across all model years. However, like any car, the STI does have some known issues that owners may face.
Common STI Issues
One common issue that STI owners face is with the transmission. The six-speed manual transmission that comes with the STI is known to have problems with the synchros, which can make shifting gears difficult.
Another common issue is with the ringland failures in the engine, which can cause a variety of problems including loss of power and engine damage. This issue is more common in older STIs, particularly the 2004-2007 models.
Finally, some owners have reported issues with blown pistons, which can also lead to engine damage. However, this issue is less common than the transmission and ringland issues.
Like any high-performance car, maintaining the STI is crucial to keeping it reliable. Subaru recommends changing the oil every 6,000 miles or six months, whichever comes first. It’s also important to regularly check the oil level and top it off if needed.
Other important maintenance items include regularly replacing the air filter and spark plugs, checking the brake pads and rotors, and ensuring that all fluids are at their recommended levels.
It’s also important to service the transmission at regular intervals. Most experts recommend that you replace the transmission fluid every 30,000 miles.
Updates or Changes to Newer Models
Subaru is always making updates and changes to the STI to improve its reliability. One major change that was made to the STI in the 2018 model year was the introduction of a new engine. This new engine is more powerful and has better fuel efficiency than the previous engine.
Another change that was made to the STI in the 2018 model year was the addition of a new performance package. This package includes a sport-tuned suspension, Brembo brakes, and Recaro seats.
Is the Subaru STI More Reliable Than Other High-Performance Cars?
When compared to other high-performance cars, the Subaru STI holds up well in terms of reliability. Cars like the Mitsubishi Lancer Evolution and the Ford Focus RS have also gained a reputation for being reliable high-performance cars.
However, it’s worth noting that these cars require more maintenance than your average car. Regular maintenance is crucial to keeping any high-performance car reliable, regardless of the make or model.
