Should You Buy the 2010 Subaru WRX?
The 2010 Subaru WRX is a high-performance bargain that delivers exceptional all-weather capability and driving thrills, but it demands a meticulous ownership approach. If you're considering this vehicle, be prepared for potential significant mechanical investments, especially if its maintenance history is anything less than perfect or if it's been modified.
The 2010 Subaru WRX is an exhilarating car, but its known engine and transmission weaknesses, coupled with a high likelihood of prior spirited use or modifications, make it a high-risk purchase for the uninitiated. If you are a dedicated enthusiast with a substantial maintenance budget and the patience to find an im…
Best Model Years
2013-2014 (later years of the GR chassis, some minor refinements)
Years to Avoid
2008-2010 (earlier GR chassis, more prevalent engine issues on unmodified cars, higher chance of abuse)

Top Risk Areas
The systems that tend to fail first on the 2010 Subaru WRX, with the typical mileage window when each becomes a concern. Detailed repair-cost ranges and exact what-to-check inspection notes are in the full report.
The EJ255 engine is notoriously susceptible to ring land failures on pistons 2 and 4, leading to low compression and excessive oil consumption. Spun rod bearings are also a risk, often due to oil starvation, improper tuning, or aggressiv…
The stock TD04 turbocharger, while robust for its size, can fail prematurely, especially if the engine's oil supply is compromised, if it's over-boosted by a tune, or if oil changes are neglected. Symptoms include smoke from the exhaust,…
The 5-speed manual transmission is often considered a weak link, especially when subjected to aggressive shifting, drag racing, or increased engine power. Synchros (particularly 2nd and 3rd gear) can wear prematurely, leading to grinding…
2010 Subaru WRX Mileage Danger Zones
The mileage windows when the 2010 Subaru WRX most commonly needs attention. Plan ahead, budget accordingly, and inspect before you cross each threshold.
Early Warning Zone
At this mileage, you should be looking for signs of abuse or improper break-in. This is where accelerated clutch wear or early suspension issues from hard driving might first manifest.
Moderate Risk Zone
This mileage range is often when the first signs of engine internal weakness (ring lands, rod knock) can begin to appear, especially if maintenance has been lax or the car has been tuned. Transmission synchro issues might also start.
Elevated Risk Zone
Many of the major engine and transmission issues become more prevalent here. Expect to consider major service items, potentially including a clutch replacement or suspension refresh. Turbocharger longevity also becomes a concern.
High Risk Zone
Beyond 120k miles, you're entering territory where an engine rebuild or replacement becomes a very real possibility. All major components will be at the end of their design life under spirited driving conditions. Exhaust systems and rust…

What it typically costs to keep the 2010 Subaru WRX on the road. Full 5-year cost-of-ownership projection and major-failure-risk forecast are in the report.
Annual Maintenance
$600-1,000
Moderate Repairs
$1,000-2,500 occasionally
How Long Does the 2010 Subaru WRX Last?
For any 2010 WRX, prioritize meticulous maintenance records over low mileage alone, as a low-mileage, abused car is far worse than a high-mileage, well-cared-for example. Be extremely wary of anything over 100,000 miles without recent major engine work or an extensive documented history.

How the 2010 Subaru WRX Compares to Rivals
The 2010 WRX offers a unique blend of AWD performance that few in its class can match for the price, making it a compelling but riskier alternative to its FWD competitors. Its direct rival, the Evo, is often even more high-strung and demanding.
More Reliable Than
- Mitsubishi Lancer Evolution (higher maintenance costs for similar performance)
- Ford Focus ST (less capable AWD, FWD bias)
- Mazdaspeed3 (torque steer, FWD, less robust transmission)
Comparable To
- Volkswagen GTI (different driving feel, but similar enthusiast appeal and some drivetrain quirks)
- BMW 1-Series (entry performance luxury, but RWD bias)
NHTSA Recalls
12 recalls on record from NHTSA. Check your VIN atnhtsa.gov to see if the repair was performed.
EXTERIOR LIGHTING:BRAKE LIGHTS:SWITCH
Subaru of America, Inc. (Subaru) is recalling certain 2014-2016 Forester, 2008-2016 Impreza sedans, 2012-2016 Impreza station wagons, 2008-2014 WRX sedans (including STI), and 2013-2017 Crosstrek vehicles. Exposure to certain contaminants may cause the brake light switch to malfunction, preventing the brake lights from illuminating and also preventing keyless ignition vehicles from starting and CVT/automatic transmissions from being able to be shifted out of Park.
AIR BAGS:FRONTAL:PASSENGER SIDE:INFLATOR MODULE
Subaru of America, Inc. (Subaru) is recalling certain 2010-2014 Tribeca, WRX, Legacy and Outback vehicles, 2010-2011 Impreza vehicles and 2010-2013 Forester vehicles sold, or ever registered, in the states of Alaska, Colorado, Connecticut, Idaho, Iowa, Maine, Massachusetts, Michigan, Minnesota, Montana, New Hampshire, New York, North Dakota, Oregon, Rhode Island, South Dakota, Utah, Vermont, Washington, Wisconsin, and Wyoming. These vehicles are equipped with certain air bag inflators assembled as part of the passenger frontal air bag modules used as original equipment or replacement equipment. In the event of a crash necessitating deployment of the passenger frontal air bag, these inflators may explode due to propellant degradation occurring after long-term exposure to absolute humidity and temperature cycling.
