Should You Buy the 2020 Subaru Ascent?
The 2020 Subaru Ascent, while offering impressive utility and standard AWD, presents a moderate reliability risk primarily due to its early adoption of Subaru's turbo-four paired with the CVT. Early models faced significant powertrain and electrical issues, demanding a thorough pre-purchase inspection and a vigilant maintenance schedule to avoid costly surprises.
The 2020 Subaru Ascent has a well-documented history of significant issues, primarily centered around its CVT and electrical system.

Top Risk Areas
The systems that tend to fail first on the 2020 Subaru Ascent, 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 CVT is prone to judder, shudder, and in more severe cases, complete failure. This often stems from torque converter issues or valve body malfunctions, leading to costly replacements or rebuilds, as detailed in TSB 16-118-19R.
Owners frequently report battery drain issues, often caused by parasitic draws or glitches within the Starlink infotainment system (TSB 15-263-19). Rearview camera malfunctions and power liftgate problems are also documented.
Premature failure of the A/C compressor or refrigerant leaks are not uncommon, leading to a loss of cooling. This can be an expensive repair, especially if the compressor itself needs replacing, sometimes noted in TSB 12-293-20.
2020 Subaru Ascent Mileage Danger Zones
The mileage windows when the 2020 Subaru Ascent most commonly needs attention. Plan ahead, budget accordingly, and inspect before you cross each threshold.
Early Warning Zone
This mileage often marks the onset of potential electrical glitches like battery drains or infotainment system issues. It's also when early signs of A/C problems or premature brake wear might appear.
CVT Scrutiny Zone
This is a critical period for the CVT, where judder, shudder, or unusual noises might become apparent. Pay close attention to transmission performance and ensure all scheduled maintenance, especially CVT fluid checks/changes, have been p…
Elevated Risk Zone
Beyond 90,000 miles, the risk of major CVT failure increases. General wear items like wheel bearings, bushings, and ignition components may also begin to fail. This is where neglect of earlier issues truly compounds.
High Risk Zone
At this mileage, expect significant component wear. If the CVT has lasted this long without major issues, it's a good sign, but continued vigilance is key. Other age-related failures become more likely, including turbo components or acce…
