How many miles does a Subaru CVT transmission last?
In general, a Subaru CVT transmission (Lineartronic) can last about 100,000 to 200,000 miles with proper care; some units reach beyond 200,000 miles, while neglect or harsh driving can shorten life to around 60,000–100,000 miles.
What determines how long it lasts
The lifespan of a Subaru CVT depends on several factors. The following list highlights the key influences and how they affect durability.
- Maintenance and fluid service: Regular CVT fluid checks and changes at Subaru-recommended intervals are crucial; failing to change the CVT fluid can accelerate wear and overheating.
- Driving conditions and habits: Frequent heavy acceleration, towing, hot climates, and stop-and-go city driving increase strain on the CVT.
- Cooling and overheating: The CVT relies on adequate cooling; overheating can degrade belts/chain, bearings, and related components.
- Model year and design: Different Subaru models use different CVT components; some revisions improve heat management and durability.
- Quality and type of fluids used: Using Subaru-approved CVT fluid and avoiding off-brand substitutes can affect longevity.
With attentive maintenance and sensible driving, you can push the lifespan toward the higher end of the range; neglect or severe conditions can shorten it.
Expected lifespans by scenario
Most owners report a broad range depending on usage and upkeep. The following ranges reflect common experiences observed in the field.
- Well-maintained, non-towing use with regular fluid changes: about 150,000–200,000 miles, with some reaching beyond 200,000.
- Average maintenance with mixed driving (city/highway): roughly 130,000–180,000 miles.
- Heavy use, towing, or irregular maintenance: around 100,000–150,000 miles, and potentially sooner if overheating occurs.
Individual results vary, and these figures reflect typical outcomes rather than guarantees from Subaru.
How to maximize longevity
Practical steps can help extend CVT life. Implement these best practices to protect your transmission.
- Follow the maintenance schedule: Adhere to Subaru's recommended CVT fluid change intervals (commonly around 60,000 miles, with more frequent changes in severe conditions).
- Keep cooling in check: Ensure the cooling system (radiator, fan, and related components) operates properly to prevent overheating.
- Use the right fluid: Use Subaru-approved CVT fluid Type B and follow guidance on changes rather than blending or substituting fluids.
- Address issues promptly: If you notice slipping, shuddering, unusual noises, or smells, have the transmission inspected early.
- Drive smoothly: Avoid aggressive starts and heavy towing unless the vehicle is properly equipped for it; gentle acceleration reduces wear.
Adhering to these measures can help protect the CVT and maximize its service life.
Signs of trouble
Early signs of CVT problems warrant prompt attention. Watch for these indicators that may precede a failure or costly repair.
- Slipping or delayed engagement when shifting into gear.
- Unusual noises (whining, clunking) or a burning smell around the transmission area.
- Overheating symptoms (dashboard warning, reduced performance in hot conditions).
- Inconsistent or illogical gear ratios, sudden acceleration changes, or limp-home mode.
If you notice any of these cues, seek diagnostics promptly to avoid further damage.
Summary
A Subaru CVT can reasonably be expected to last roughly 100,000 to 200,000 miles with diligent maintenance and careful driving; some vehicles reach beyond 200,000 miles, while others fail earlier due to neglect or extreme use. Following maintenance intervals, using the correct fluid, and addressing issues early can maximize longevity.
What is the average lifespan of a Subaru CVT transmission?

Is the CVT transmission reliable in a Subaru?
Subaru CVT reliability is mixed; while older models from roughly 2010-2015 had significant issues and an extended warranty, newer Subarus have improved CVT technology. Proper and frequent maintenance, especially replacing the CVT fluid according to the manufacturer's recommendations (or even more frequently), is crucial for ensuring longevity and avoiding common problems like valve body issues. Overall, the reliability of newer Subarus with their updated CVTs is considered good, but poor maintenance can still lead to costly repairs.

Reliability of older vs. newer models
- Older Models (approx. 2010-2015): Some earlier models had well-documented reliability problems, leading Subaru to extend the warranty for many vehicles to 10 years or 100,000 miles.
- Newer Models: Newer Subarus feature updated CVT technology and software, and are considered to be much more reliable. Issues are less likely, but not impossible, and proper maintenance is still essential.
Common issues and maintenance
- Common failures: The most common failure points in older CVTs were the valve body (specifically the solenoids) and the torque converter. These issues often resulted in symptoms like delayed acceleration, shuddering, or a high-pitched whining sound.
- Maintenance is key:
- Proper maintenance, especially regular CVT fluid changes, is critical for longevity.
- Many modern Subarus lack a dipstick, making a professional fluid check and change even more important.
- It is recommended to have the CVT fluid drained and filled every 30,000 miles, rather than treating it as a "lifetime" fluid, according to this YouTube video.

What to do if you have a problem
- If you experience issues, especially while under the extended warranty, take the vehicle to a Subaru dealer for diagnosis and repair.
- Be aware that damage caused by neglect or using improper fluids may not be covered by the warranty.
What years did Subaru have CVT transmission problems?
Subaru had significant CVT transmission problems primarily in models from the 2010 to 2015 range, particularly the first-generation Lineartronic CVT. Specific issues included torque converter clutch failures and other problems like chain slip, affecting models like the Outback, Legacy, Forester, Impreza, and Crosstrek during these years. Subaru extended the warranty for many 2010-2015 vehicles to address these early reliability issues.
Years and models with significant CVT problems
- Outback & Legacy: 2010–2015
- Impreza: 2012–2015
- Crosstrek: 2013–2015
- Forester: 2014–2015 (with 2.5L engine); some 2014–2018 models with FB25 engine
- WRX: 2015 (2.0L engine)

Common problems
- Torque converter clutch failure: This was a major issue in early models (around 2010–2013), causing the car to stall when stopping. The torque converter was redesigned to fix this.
- Chain slip: This occurred in some early models, often during highway cruising.
- Valve body and solenoid issues: These problems have been reported in various model years.
- Oil pump chain leaks: This became an issue in later models.
What to know
- Extended warranty: Subaru extended the CVT warranty to 10 years or 100,000 miles for many 2010–2015 vehicles due to these early problems.
- Redesigned transmissions: Newer models (especially after 2015) generally feature improved CVTs, but some issues can still arise.
- Maintenance is key: Proper and timely maintenance, including fluid changes, is crucial to help prevent issues.
Will a CVT transmission last 200,000 miles?
But excellent owner care can lengthen this projection. Indeed, some owners who keep to the factory-specified service intervals, use the recommended lubricant(s) and avoid abusive driving habits can get up to 200,000 trouble-free miles with a CVT.
