Does Subaru Ascent have transmission problems?
Yes, there have been transmission-related complaints about the Subaru Ascent, particularly with its continuously variable transmission (CVT) in some early model years. Subaru has responded with software updates, service bulletins, and recalls to address these concerns, and many owners report reliable operation with proper maintenance. This article examines the issues reported, the model-year context, and practical guidance for buyers and current owners.
What drivers are reporting
Automotive outlets and owner forums have highlighted a range of CVT-related symptoms in certain Ascent models. The following issues have been most frequently mentioned by readers and reviewers:
- Shuddering or surging sensations during low-speed driving or light acceleration
- Delayed engagement or hesitation when starting to move from a stop
- Unusual noises or perceived slipping when the CVT is under load
- Warning lights or diagnostic trouble codes related to the transmission
- Isolated reports of transmission failure or transient loss of power
These problems are not universal and tend to vary by model year, maintenance history, and driving conditions. Many owners experience smooth CVT performance with routine maintenance and software updates.
Subaru's response and recalls
In response to reported CVT concerns, Subaru has issued several service actions and advisories aimed at improving transmission behavior and longevity. Key elements of the automaker’s approach include:
- Software updates and recalibration of the CVT control module to improve shift feel and response
- Service bulletins addressing CVT fluid specification, cooling, and related components to reduce wear or overheating
- VIN-specific recalls or dealer campaigns for CVT-related components or software, with eligibility determined by vehicle identification number
- Guidance to use factory-specified CVT fluid and follow Subaru’s recommended maintenance intervals
Owners should verify that any recalls or TSB-related repairs have been completed, keep thorough service records, and check for warranty coverage if a defect is diagnosed. If considering a used Ascent, confirming prior CVT service and recall work can be important to ongoing reliability.
Model-year considerations and reliability perspective
The Ascent debuted in 2019 as Subaru’s three-row family SUV, powered by a 2.4-liter turbocharged engine paired exclusively with a CVT (Subaru’s Lineartronic transmission). Early model years drew more attention to CVT behavior, while later updates and ongoing dealer actions helped to mitigate many complaints. Overall reliability for the Ascent remains competitive within the midsize SUV segment, but prospective buyers and current owners should pay particular attention to transmission history, recall status, and routine CVT maintenance. When evaluating a used Ascent, prioritize vehicles with documented CVT service completion and up-to-date software updates.
Maintenance and inspection tips
To reduce the risk of CVT-related problems and to support long-term reliability, consider these steps:
- Use Subaru-approved CVT fluid and follow the recommended service intervals
- Keep up with preventive maintenance and address any warning lights promptly
- Check for open recalls or TSB campaigns and have them completed by an authorized dealer
- When test-driving a used Ascent, assess acceleration smoothness, hesitation, and any unusual CVT behavior
In addition, maintain overall vehicle health, including the cooling system, as CVTs can be sensitive to overheating or overheating-related fluid degradation.
Summary
Bottom line: The Subaru Ascent has experienced transmission-related complaints in some model years, predominantly involving the CVT’s behavior rather than catastrophic failures. Subaru has addressed these issues with software updates, service bulletins, and recalls, and many owners report solid reliability with proper maintenance. Buyers and owners should verify recall and service history, use the correct CVT fluid, and stay current with recommended maintenance to maintain smooth operation.
For readers seeking a final takeaway: while the CVT in the Ascent can present challenges in certain cases, informed purchasing, diligent maintenance, and timely dealership support significantly influence long-term reliability. Always check current recall status for any used vehicle and have a qualified technician assess the transmission before purchase.
