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 2019 Subaru Wrx sti problems

The Subaru WRX STI 2019 is a high-performance sports sedan that is known for its all-wheel-drive capability and tuned engine. However, like any other car, it has its share of common problems that have been reported by owners.

One of the most common problems with the Subaru WRX STI 2019 is engine issues. The engine is one of the most critical components of the car, and any problems can significantly affect its performance and reliability. The engine issues reported with the Subaru WRX STI 2019 include internal engine problems such as rod bearing and piston ring failures, oil leaks, and defective turbochargers. These issues can cause the engine to misfire, lose power, and consume oil at an alarming rate. In some cases, these issues can lead to costly repairs and even legal arguments

Another common problem with the Subaru WRX STI 2019 is clutch problems. Clutch problems are a common issue with earlier models of the Subaru WRX, and the 2019 model is no exception. Clutch problems can cause the car to slip, jerk, and lose power, making it difficult to drive. In some cases, clutch problems can lead to premature clutch failure, which can be costly to repair.

The Subaru WRX STI 2019 also has issues with the turbocharger. A defective turbocharger can cause the engine to misfire and lose power, which can significantly affect the car's performance. In some cases, the defective turbocharger can cause the engine to consume more fuel than usual, leading to increased fuel costs.

Faulty oxygen sensors are another common problem with the Subaru WRX STI 2019. Oxygen sensors are critical components of the car's engine management system, and any problems can significantly affect the car's performance and fuel efficiency. Faulty oxygen sensors can cause the engine to misfire, idle roughly, and consume more fuel than usual. In some cases, faulty oxygen sensors can cause the check engine light to come on, indicating that there is a problem with the engine.

In addition to these common problems, the Subaru WRX STI 2019 also has issues with the exhaust system. Smoke out of the exhaust is a common problem with the Subaru WRX STI 2019, which can be caused by a number of engine problems, including STI ringland failure. STI ringland failure is a semi-common issue affecting certain Subaru STI engines, where the groove that holds the piston rings cracks and breaks, causing the piston to become damaged. This can lead to a number of engine problems, including smoke out of your exhaust, loss of power, poor idling quality, and loss of compression.

In summary, the Subaru WRX STI 2019 is a high-performance sports sedan that is known for its all-wheel-drive capability and tuned engine. However, like any other car, it has its share of common problems that have been reported by owners. These problems include engine issues, clutch problems, turbocharger issues, faulty oxygen sensors, and exhaust system problems. If you are considering buying a Subaru WRX STI 2019, it is essential to be aware of these common problems and take the necessary steps to maintain and service the car regularly to ensure its reliability and performance.

1: Warm it up before driving off in cold weather.

You're just increasing load on the engine for no reason.
