The Subaru WRX STI is a variant of the Subaru WRX sedan produced by in-house tuning company Subaru Tecnica International between 2014 and 2021. It succeeded the Subaru Impreza WRX STI. The VA WRX STI was the last vehicle produced with the famous EJ257 engine. Production of the WRX STI may resume production in the next generation (Presumably codenamed VC) WRX, however there are currently no plans for a VB WRX STI. STI also offers many factory-backed accessories usually available from dealerships, and accented in STI's signature cherry blossom, a tribute to the iconic tree of the same name from the brand's homeland of Japan.

First Generation (VA; 2014-2021)

The VA WRX STI was released in 2014 alongside the VA WRX. It featured uprated brakes, the famous Subaru Technica International tuned EJ257 4-cylinder engine, an uprated 6 speed manual transmission, along with a unique body kit and spoiler. Interior upgrades include an STI-exclusive gauge cluster, shifter knob, and other unique touches, including Recaro bucket seats in certain models. The WRX STI for the most part featured a red accented interior, over the WRX's black and grey.

Starting with the MY2016 update, the WRX STI gained fluorescent green brake callipers, which was a hit among the Subaru community, and is now an easy identifier of the WRX STI.

In 2020, Subaru announced they would be phasing out the WRX STI along with the EJ257, the last variant of the ageing EJ engine, with the release of the VB series WRX in 2021. Subaru introduced the STI WRX EJ25 Final Edition, based on Subaru's flagship STI Spec R. The EJ25 Final Edition features a range of upgrades including BBS 19” gold forged aluminium wheels, silver Brembo calipers, black door mirror covers, front grille pinstripe in STI cherry blossom, Final Edition engine cover plate, and numbered EJ25 Final Edition badge. Only 75 were produced for markets across the globe.

Common 2009 Subaru Wrx sti problems

The Subaru WRX STI is a high-performance variant of the Subaru WRX, which was first introduced in 1994. Over the years, the WRX STI has gained a reputation for its sporty appearance and impressive performance. However, some model years have been plagued with issues that potential buyers should be aware of. One of the most common problems with the Subaru WRX STI is the possibility of head gasket failure. This issue is well-known among Subaru owners and can result in significant engine damage if not addressed promptly. Symptoms of head gasket failure include overheating, coolant leaks, and white smoke from the exhaust. Another common issue with the WRX STI is faulty oxygen sensors and rough running. Oxygen sensors play a crucial role in regulating the engine's fuel-air mixture, and a faulty sensor can result in poor performance and decreased fuel efficiency. Additionally, bad camshaft seals can also be a problem with the WRX STI. These seals are responsible for preventing oil leaks, and a failure can result in significant oil loss and potential engine damage. When it comes to reliability, the Subaru WRX STI has scored poorly, with a score of 2.5/5 on RepairPal, placing it at the bottom of the pack. This low score is due to the car's high repair costs and frequent breakdowns. In terms of specific model years to avoid, the 2009 Subaru WRX STI is one to be wary of. These failures can result in significant engine damage and require costly repairs. When considering purchasing a used Subaru WRX STI, it's essential to thoroughly inspect the car for any signs of oil leaks, smoke from the exhaust, knocking noises from the engine, or whining from the turbocharger. Additionally, checking the oil level and quality and ensuring there are no traces of oil in the coolant is crucial. In conclusion, while the Subaru WRX STI is a high-performance car with a loyal following, potential buyers should be aware of the common issues and reliability concerns associated with certain model years. Thoroughly inspecting the car and addressing any issues promptly can help ensure a reliable and enjoyable ownership experience.

Is 2009 a good year for WRX?

Overall, this has been a good car. It's fast, handles well, is outstanding in snow and rain, and in general has had less major issues than other cars I've owned with this mileage (other than the 9000 mile engine replacement). The low-key looks of the 09 Sedan is nice - it's still a WRX, but the police dont' notice it.

Summary: Subaru of America, Inc. (Subaru) is recalling certain model year 2008-2011 Impreza, 2008-2014 WRX and STI, and 2009-2013 Forester vehicles, currently, or formerly, registered in Connecticut, Delaware, Illinois, Indiana, Iowa, Maine, Maryland, Massachusetts, Michigan, Minnesota, Missouri, New Hampshire, New Jersey, New York, Ohio, Pennsylvania, Rhode Island, Vermont, West Virginia, Wisconsin and the District of Columbia that were remedied under recall 14V-311 prior to December 23, 2014. The brake lines may experience brake line corrosion due to salt water splashing on the brake lines through a gap in the fuel tank protector.
Consequence: Brake fluid may leak due to the brake line corrosion and may result in longer distances being required to slow or stop the vehicle, increasing the risk of a crash.
Remedy: Subaru will notify owners, and dealers will apply an anti-corrosion wax to the four-way joint connector area of the brake line system, free of charge. The recall began on January 27, 2015. Owners may contact Subaru customer service at 1-800-782-2783. Subaru's number for this recall is WQQ-52. Notes: This recall is specific to affected Forester, Impreza, WRX, and STI customers who had their car remedied under NHTSA recall no. 14V-311 prior to December 23, 2014. Subaru has determined that this remedy was inadequate due to incomplete repair instructions provided to dealers. Affected Forester, Impreza, WRX, and STI vehicles that were not repaired under NHTSA recall no. 14V-311 prior to December 23, 2014 will continue to be processed under NHTSA recall no. 14V-311.

If no brake fluid seepage is observed, the affected areas will be rustproofed with anti-corrosion wax. If brake fluid seepage is observed, the brake lines will be replaced followed by rustproofing with anti-corrosion wax. These services will be performed free of charge.
