Subaru Ascent Years to AvoidThe weakest years — and the one you should buy instead
After reviewing every Subaru Ascent we've analyzed (7 years), these are the 2 weakest. Each one has either an absolute low reliability score, chronic repair issues, or unusually high ownership costs relative to other Ascent years.
Proceed with caution
2019 Subaru Ascent
The 2019 Subaru Ascent offers compelling family-hauling capabilities and standard AWD, but its inaugural model year suffered from significant reliability concerns, primarily centered around its continuously variable transmission (CVT). While many owners enjoy their Ascents, the potential for costly CVT failures makes this a vehicle to approach with considerable caution; comprehensive pre-purchase inspections are paramount to mitigate risk.
Why this year scores low
Owners frequently report shuddering, hesitation, slipping, and complete transmission failure. This often stems from torque converter issues, valve body problems, or internal component wear. Subaru issued multiple technical service bulletins (TSBs) for software updates and component replacement.
Common complaints include parasitic battery drain leading to dead batteries, freezing or crashing infotainment screens (Starlink system), non-responsive touchscreens, and occasional issues with the power liftgate motor or sensors.
Early models of the FA24DIT engine, especially in the Ascent, have been linked to PCV valve failures. This can lead to excessive oil consumption, oil leaks, and potentially turbocharger damage if not addressed. Some owners report burning a quart every 1,000-3,000 miles.
Proceed with caution
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.
Why this year scores low
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.
