2010 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.

Common 2010 Subaru Wrx sti problems
The Subaru WRX STI is a high-performance variant of the Subaru WRX, known for its rally-inspired design and turbocharged boxer engine. The 2010 Subaru WRX STI, in particular, has received some criticism from owners regarding common problems. Here are some of the issues that have been reported:
- Head Gasket Failure: One of the most common problems with the 2010 Subaru WRX STI is head gasket failure. This issue is often associated with the EJ25 engine, which was used in the 2010 model. The head gasket is a critical component that seals the cylinders, preventing coolant and oil from mixing. When it fails, coolant can leak into the engine, causing it to overheat and potentially leading to engine damage.
- Faulty Oxygen Sensors and Rough Running: Another issue that has been reported by owners is faulty oxygen sensors, which can cause the engine to run roughly. Oxygen sensors measure the amount of oxygen in the exhaust gases, and if they fail, it can affect the engine's fuel mixture, leading to poor performance and decreased fuel efficiency.
- Bad Camshaft Seal: A bad camshaft seal can also be a problem in the 2010 Subaru WRX STI. The camshaft seal is responsible for preventing oil from leaking out of the engine. If it fails, oil can leak onto the engine's timing belt, potentially causing it to slip or break, which can lead to significant engine damage.
- Piston Failures: Piston failures are another common problem with the 2.5-litre engine used in the 2010 Subaru WRX STI. These failures can be caused by a variety of factors, including poor maintenance, high horsepower modifications, and excessive heat. Piston failures can lead to engine damage, and in some cases, complete engine failure.
- Oil Starvation: Oil starvation can also be a problem in the 2010 Subaru WRX STI. This can be caused by leaks, g-forces when cornering, or a lack of maintenance. When the engine doesn't receive enough oil, it can lead to a host of problems, including rod bearing and turbocharger failures.
- Engine Troubles: Some owners have reported engine troubles, including issues with oil leaking and defects in the turbocharger. These problems can be expensive to repair and can lead to significant engine damage if not addressed promptly.
When considering purchasing a 2010 Subaru WRX STI, it's important to be aware of these common problems. Proper maintenance, including regular oil changes and inspections, can help prevent many of these issues. Additionally, it's important to thoroughly inspect any potential purchase for signs of oil leaks, smoke from the exhaust, knocking noises from the engine, or whining from the turbocharger. A test drive can also help identify any hesitation, miss-fires, or a lack of power under load, which could indicate engine problems.
