Are Subaru WRX transmissions reliable?

The Subaru WRX is a popular high-performance sports car known for its turbocharged engine and all-wheel-drive system. When it comes to the reliability of the WRX's transmission, the answer is generally positive, though there are some caveats to consider.

Transmission Options in the Subaru WRX

The Subaru WRX is available with two transmission options: a 6-speed manual transmission and a continuously variable transmission (CVT). The manual transmission is often considered the more enthusiast-oriented choice, as it allows the driver more control over the power delivery. The CVT, on the other hand, is designed for improved fuel efficiency and smoother power delivery, though it may not provide the same level of engagement for some drivers.

Reliability of the WRX Transmission

Overall, the Subaru WRX's transmissions are generally considered reliable. The manual transmission, in particular, has a reputation for being durable and well-engineered. The CVT, while not as widely praised, has also proven to be relatively reliable, with proper maintenance and care.

However, it's important to note that the WRX's high-performance nature can put additional stress on the transmission, especially if the vehicle is driven aggressively or used for track days. In these cases, the transmission may require more frequent maintenance or even replacement, depending on the driving conditions and the owner's maintenance habits.

Tips for Maintaining WRX Transmission Reliability

• Follow the manufacturer's recommended maintenance schedule, including regular fluid changes.


• Avoid excessive clutch slipping or high-RPM launches, which can put additional strain on the manual transmission.


• If using the CVT, avoid towing heavy loads or driving in extreme conditions, as this can shorten the transmission's lifespan.


• Consider upgrading to a more robust aftermarket transmission if the vehicle will be used for high-performance driving or racing.

By following these tips and maintaining the transmission properly, Subaru WRX owners can generally expect their vehicle's transmission to provide reliable performance for many years of ownership.

Transmission Issues
Both CVT and manual transmission in the WRX have had their share of problems.

Should I avoid CVT transmission?

You may want to avoid a CVT if you plan to tow heavy loads, drive aggressively, or are concerned about potential long-term reliability issues, especially with specific brands like Nissan, as some older or poorly maintained CVTs can be prone to costly failures. However, CVTs offer fuel efficiency benefits and a smooth, gearless ride that can be ideal for many drivers who don't engage in heavy towing or aggressive driving, notes ICICI Lombard.

Reasons to avoid a CVT

• Towing and heavy loads: CVTs are not designed for heavy-duty use like towing trailers or boats, as the high torque can damage the transmission. 
• Performance driving: Aggressive driving and high-performance applications are not ideal for CVTs. The "rubber band effect," where the engine revs high but the car's speed catches up slowly, can be a negative for performance-oriented drivers. 
• Reliability concerns: Some brands, particularly older models from Nissan, have a reputation for reliability issues and premature failure. While newer CVTs are improving, some drivers are wary of their long-term durability compared to traditional automatics. 
• Cost of repair: When a CVT fails, it often requires a full replacement, which can be very expensive, sometimes exceeding the car's market value. Specialized knowledge and parts are also needed, which can increase costs. 
• Maintenance requirements: CVTs have specific fluid and maintenance requirements, and neglecting them can lead to premature failure. 
• "Rubber band effect": Some drivers dislike the sensation of the engine revving high and staying there while the car accelerates, which can feel disconnected compared to a traditional geared transmission.

Reasons to consider a CVT

• Fuel efficiency: CVTs are often more fuel-efficient, especially on the highway, because they allow the engine to stay within its most efficient RPM range. 
• Smooth ride: The continuous, gearless nature of a CVT provides a very smooth driving experience without the "jerk" of traditional gear shifts. 
• Better acceleration: CVTs can offer rapid acceleration because they can provide an infinite number of gear ratios to match the engine's needs.

How to mitigate risks if you choose a CVT

• Choose a reputable manufacturer: Some manufacturers have a better track record with CVTs than others. Research the specific model you are interested in. 
• Perform regular maintenance: Follow the manufacturer's recommended maintenance schedule, especially for fluid changes, and consider changing the fluid more frequently if you engage in any demanding driving conditions. 
• Allow the engine to cool down: After hard driving, let the engine idle for a minute or two to allow the transmission's cooling fan and oil circulation to dissipate the trapped heat before shutting it off completely. 
• Avoid heavy towing: Do not use a CVT vehicle for heavy towing. 
• Consider the warranty: Make sure to get an extended warranty if available, and understand what the warranty covers. 
• Test drive carefully: Pay attention to how the transmission feels during acceleration. Any rough shifts, jerks, or whining sounds are potential warning signs. 

Is the Subaru WRX automatic transmission reliable?

The reliability of the Subaru WRX automatic is generally considered good, especially with newer models, but is mixed and dependent on model year and maintenance. Automatic transmissions (CVT) in recent generations are reliable for daily driving, though they have limitations at extreme power levels. The overall reliability is considered average to above average within its class, with average repair costs but a higher chance of severity when issues do arise.

Positive aspects

• Improved reliability: The WRX platform has improved significantly in recent years, particularly models with the FA20 (2015-2021) and FA24 (2022+) engines, which have low failure rates. 
• CVT performance: The automatic CVT transmission is generally reliable for daily driving and has been designed to handle the demands of spirited driving. It's praised for providing a continuous, torquey, and direct driving experience. 
• Strong overall ratings: Recent models are considered very reliable sports cars, with Subaru ranking highly for brand-wide reliability. 

Potential concerns

• Higher-than-average repair costs: While the frequency of repairs is average, the cost of repairs is higher than the average compact car due to the nature of the performance parts. 
• Severe issues: When issues do arise, there is a higher chance they will be severe, which could lead to higher repair costs. 
• Maintenance and driving habits: To maintain reliability, proper maintenance is crucial, including using premium fuel and following recommended service intervals. Driving habits, such as letting the turbo warm up and cool down, are also important. 
• Tires: Due to the all-wheel-drive system, all tires must be replaced at the same time to avoid damaging the differentials, which can add to the long-term cost. 

Which model years to consider

• 2022-2025 models: These are considered very reliable, with the FA24 engine proving robust. 
• 2015-2021 models: These models are also considered reliable, with the FA20 engine performing well, especially with good maintenance.
