2011 Subaru Wrx sti problems
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.
