About Subaru WRX STI
Subaru WRX STI is a compact vehicle manufactured by Japanese automaker Subaru division of Fuji Heavy Industries (FHI) since 2015. As a matter of fact, as early as October 2007 at the Tokyo Auto Show, Subaru WRX STI was introduced. But just like the Subaru WRX, Subaru WRX STI got its name until the third generation Subaru Impreza. At the same time, Subaru WRX STI is also a high-performance variant of Subaru Impreza.
As of 2014, Subaru has decided to move away from marketing the WRX STI under the Impreza name, until then, Subaru WRX STI was officially independent. As a 4-door sedan and a 5-door hatchback, Subaru WRX STI was introduced in America in 2015. It retains the same engine as the previous generation STI. Subaru WRX STI is powered by a 2.5 L EJ257 engine with dual AVCS that could produce 310 horsepower. Japanese version Subaru WRX STI is powered by a 2.0 L EJ207 engine, which could produce 323.5 horsepower and 318 pound-feet of torque. There are Subaru WRX STI Launch Edition, Subaru WRX STI S207, Subaru WRX STI Hyper Blue special edition series and Subaru WRX STI Premium editions available for Subaru WRX STI. And available transmissions include 6-speed manual and Continuously Variable automatic transmissions.
Subaru WRX STI Common Problems & Maintenance Tips
Still, even as a high-performance variant of Subaru Impreza, Subaru WRX STI still carries over some design ideas from Subaru Impreza. In this way, some design flaws and problems caused by design flaws would also appear on Subaru WRX STI:
First, engine performance reduced. Subaru WRX STI drivers told that as accumulation of mileage, the engine starts to make whining, knocking or metallic sounds and runs more roughly. It would be very difficult to start the engine even unable to start. What's more, they have to add fuel more often than usual due to the engine consumes more fuel and oil would leak from engine. While accelerating, drivers could feel a complete loss of power. Once your Subaru WRX STI's Check Engine Light is activated, then the oil filter, fuel pump, speedometer cable, A/C idler pulley and timing cover are all what you need to check.
Second, suspension failure. A proper operation of suspension system guarantees a comfortable and pleasant driving trip. However, in Subaru WRX STI, owners complained that the front brakes and tires wear more severely than other parts, so the uneven tire wear would let the vehicle bottom out or tilt to one side. However, the grinding or roaring noise coming from the tire area may also be one reason of the abnormal tire wear. And the vibrating steering wheel makes it hard for drivers to control the vehicle. These symptoms are basically caused by the WRX STI wheel bearing, WRX STI wheel seal and WRX STI coil spring insulator.
As a matter of fact, some electrical parts in Subaru WRX STI are also very vulnerable. For example, the brake light switch. If your Subaru WRX STI's brake lights either stay on when they shouldn't or do not turn on at all, then you probably need to replace it. What's more, some parts that work under harsh conditions for long time also need your extra attention. Wiper blade, fog light, headlight, antenna and so on, they all work in open environment, so you had better maintain them in a regular basis.
