Does the Subaru Forester have transmission problems?

Some Subaru Forester models have reported transmission problems, especially with the CVT; however, many drivers experience reliable service. The likelihood of issues varies by model year, maintenance history, and driving conditions.

Understanding the Forester’s transmissions

The Forester has used several transmissions across its generations. Most recent models rely on Subaru’s Lineartronic continuously variable transmission (CVT), designed to improve fuel efficiency and smooth power delivery. Earlier generations offered traditional automatics or manual options in some trims. While the CVT aims to be economical and seamless, some owners have raised concerns about durability and response under specific conditions.

Common symptoms reported

Owners and technicians have noted several recurring CVT-related symptoms. If you notice any of these, a diagnostic check is warranted:

• Jerking or shuddering during acceleration or while cruising


• Slipping or lag before the transmission engages gears


• Unusual noises such as whining or clunking from the transmission area


• Illumination of the check engine or transmission warning light


• Harsh or delayed upshifts or downshifts


• Overheating or a burning smell from the vicinity of the CVT

Not every Forester will experience these symptoms, and problems can sometimes stem from related drivetrain components or fluid condition rather than the CVT itself.

Model-year patterns and reliability

Notable design changes and updates by year

Public reports and consumer publications have highlighted higher CVT-related complaints in certain generations, particularly for early- to mid-2010s Foresters that used the original CVT design. Later model years include software tweaks and redesigned CVT components intended to reduce issues. Always verify a specific vehicle’s recall status and warranty coverage for its year and VIN.

• Early- to mid-2010s Foresters with the original CVT design have been the focus of many complaints


• Subsequent model years include updates intended to improve CVT reliability, though isolated problems can still occur

Because reliability can depend heavily on maintenance and usage, checking service history and potential recall notices is essential before purchasing a used Forester.

What to do if you suspect CVT problems

If you notice transmission symptoms, follow a careful diagnostic path to determine the cause and remedy:

1. Document symptoms, mileage, and driving conditions; gather maintenance records, including CVT fluid service


2. Check for active recalls or service campaigns on the exact vehicle VIN via NHTSA or Subaru’s recall portal


3. Schedule a diagnostic with a Subaru dealer or a reputable transmission shop; request CVT fluid inspection and follow recommended service


4. Ask about software updates, warranty options, or recall-related repairs that may apply to your vehicle


5. Review repair options and costs, including potential CVT replacement, and weigh them against ownership plans

Timely diagnosis can prevent further damage and clarify whether the fix is a simple fluid service, software update, or more extensive work under warranty.

Warranty coverage and recalls

Subaru has conducted recalls and offered coverage for CVT-related issues on certain Foresters. To determine coverage for your vehicle, check:

• Current recall notices using the VIN on the NHTSA recall page or Subaru’s official recall portal


• Whether there is an extended CVT warranty or service campaign applicable to your model year


• Maintenance history and any prior CVT repairs that could affect eligibility

Dealerships can confirm eligibility for recall work, warranty coverage, and the corresponding repair steps or costs if applicable.

Bottom line and recommendations

Takeaway: the Subaru Forester can experience CVT-related transmission problems in some model years, particularly in older generations. If you own a Forester or are considering a used purchase, verify maintenance history, review recall notices, and understand any warranty coverage for the exact year and VIN. For ongoing symptoms, seek a professional diagnostic to determine whether a fluid service, software update, or more extensive transmission work is required.

Summary

The Forester’s transmission reliability varies by model year. CVT-related concerns have been reported, especially in older generations, but updates in later years have aimed to improve reliability. Regular maintenance, awareness of recalls, and VIN-specific warranty information help owners manage potential issues. Overall, many Forester owners enjoy long, trouble-free operation, but due diligence is essential when evaluating a used vehicle or diagnosing symptoms.

What is the biggest issue with a Subaru Forester?

And all that but it lacks power the engine only makes a modest 180HP. And 178 lb feet of torque.

What years did the Subaru Forester have a bad transmission?

Yes, the Transmissions of Foresters from 2014 - 2018 are known to have problems. Subaru extended the warranty on CVT transmissions to 10 years or 100000 miles.

What year did Subaru have transmission problems?

Subaru CVT transmission problems are most common in models from the 2010-2015 range, including the Legacy and Outback, with specific issues also affecting the Impreza (2012-2015), Crosstrek (2013-2015), and Forester (2014-2015). These issues can include stalling, torque converter failures, and valve body problems, leading Subaru to offer extended warranties on many of these vehicles.

Specific model years and issues

• Legacy and Outback (2010-2015): These models, especially those with the first-generation Lineartronic CVT, are frequently cited for issues like torque converter clutch failure (leading to stalling) and general valve body failure. 
• Impreza (2012-2015): This model year range was included in the extended warranty for CVT issues. 
• Crosstrek (2013-2015): These years are noted for having transmission problems. 
• Forester (2014-2015): Models with either the 2.5-liter or 2.0-liter turbocharged engine in this range were affected. 
• Ascent (2019): While a newer model, the first year of the Ascent is noted for numerous problems, including CVT issues and engine concerns.

Solutions and considerations

• Extended warranty: Subaru offered extended warranties on many affected 2010-2015 vehicles, and the company has been known to cover repairs outside of the warranty period under certain circumstances. 
• Maintenance is key: Regular maintenance, especially timely fluid changes, can significantly extend the life of a Subaru CVT. 
• Contact Subaru: If you are experiencing issues, contact Subaru of America to see what options are available for coverage. 

Do Subaru Foresters have transmission problems?

Yes, some Subaru Foresters have transmission problems, particularly with their Continuously Variable Transmissions (CVTs), which can experience issues like shuddering, jerking, delayed shifting, and unusual noises. These problems can arise from factors like degraded transmission fluid, worn internal components, or software glitches. While Subaru has extended the CVT warranty on some models to address these concerns, regular maintenance, including timely fluid changes, is crucial for longevity. 
Common transmission problems

• Shuddering and jerking: This can occur when accelerating from a stop or going uphill. 
• Delayed or jerky shifting: You might notice a hesitation or rough feel when the vehicle shifts gears. 
• Unusual noises: Whining, humming, or clunking sounds from the transmission are potential indicators of a problem. 
• Delayed acceleration: The vehicle may hesitate before it starts to accelerate. 
• Sudden failure: In some cases, the transmission can fail completely, leading to a loss of forward or reverse gear engagement. 

Causes and contributing factors

• Degraded transmission fluid: The fluid in CVTs is critical for operation and cooling. If it's old, overheated, or broken down, it can lead to premature wear and failure. 
• Internal wear: Components like the valve body or clutch packs can wear out over time. 
• Software issues: Software updates have been issued by Subaru to address some problems, though they don't always fully resolve the issue. 

What you can do

• Perform regular maintenance: Follow the recommended service schedule, which includes checking and replacing the transmission fluid. Some mechanics suggest fluid changes as frequently as every 15,000 to 30,000 miles for optimal performance. 
• Be aware of extended warranties: Subaru extended the powertrain warranty on certain CVT models to help cover potential issues. 
• Address issues promptly: If you experience any of the symptoms listed above, have your vehicle inspected by a qualified mechanic. Ignoring the problem can lead to more extensive and costly damage.
