Introduction: Is the Subaru Ascent Worth It?

The Subaru Ascent burst onto the scene in 2018 as the brand’s first true three-row SUV, designed to compete with heavyweights like the Honda Pilot, Toyota Highlander, and Ford Explorer. With seating for up to eight passengers, standard all-wheel drive, and Subaru’s reputation for safety and durability, it quickly became a favorite among families. But like any vehicle, especially a new model, the Ascent had its growing pains—especially in its earliest years.

If you’re considering buying a used Subaru Ascent, you’re probably wondering: Which Subaru Ascent years to avoid? That’s a smart question. While the Ascent has evolved into a solid, dependable SUV, certain model years come with known problems that could lead to expensive repairs or frustrating breakdowns. In this guide, we’ll walk you through the best and worst years for the Subaru Ascent, highlight common issues, and give you practical tips to make a smart purchase decision.

Why Knowing Which Subaru Ascent Years to Avoid Matters

Buying a used car is all about balancing value and risk. A lower price tag might seem appealing, but if it comes with a history of transmission failures or engine problems, you could end up spending more in the long run. That’s why understanding which Subaru Ascent years to avoid is crucial—especially for a vehicle that’s meant to carry your family safely for years.

The Ascent’s early years were marked by teething issues common in new vehicle launches. From oil consumption to infotainment bugs, these problems affected real owners and led to recalls, complaints, and even class-action lawsuits. Later models benefited from Subaru’s updates and fixes, making them much more reliable. By knowing which years to steer clear of—and which to consider—you can avoid costly surprises and find a dependable SUV that fits your needs.

The Importance of Model Year Research

Every car model goes through a “honeymoon phase” when it’s first introduced. Engineers and designers work hard to get it right, but real-world use often reveals flaws that don’t show up in testing. The first year of a new vehicle—like the 2019 Subaru Ascent—is especially risky. Owners report issues that manufacturers may not yet be aware of, and fixes can take months or even years to roll out.

By the time the 2022 model year arrived, Subaru had addressed many of the Ascent’s early problems. That’s why researching model years isn’t just helpful—it’s essential. A few thousand dollars in savings on a 2019 model could cost you ten times that in repairs down the road. Knowing which Subaru Ascent years to avoid helps you make a smarter, safer investment.

The 2019 Subaru Ascent: Proceed with Caution

The 2019 Subaru Ascent was the first model year of this new SUV, and while it brought excitement, it also brought a host of problems. As the debut year, it’s often considered one of the riskiest Subaru Ascent years to buy—especially if you’re looking for a trouble-free ownership experience.

Excessive Oil Consumption

One of the most common complaints from 2019 Ascent owners was excessive oil consumption. Many drivers reported needing to add a quart of oil every 1,000 to 1,500 miles—far beyond what’s considered normal. Subaru eventually acknowledged the issue, attributing it to piston ring design flaws that allowed oil to burn in the combustion chamber.

This problem wasn’t just inconvenient—it was potentially dangerous. Low oil levels can lead to engine damage, especially if drivers don’t check their oil regularly. Some owners even reported engine failure due to oil starvation. Subaru issued technical service bulletins (TSBs) and extended warranties for affected vehicles, but the issue lingered for many.

CVT Transmission Shudder and Hesitation

The 2019 Ascent uses a continuously variable transmission (CVT), which is designed for smooth, efficient power delivery. However, many owners complained of a noticeable shudder or hesitation during acceleration, especially from a stop or when merging onto highways. This “jerky” feeling made the driving experience less enjoyable and raised concerns about long-term reliability.

Subaru released software updates to improve CVT performance, but some drivers said the problem persisted. In extreme cases, the transmission would fail entirely, requiring a costly replacement. While not every 2019 Ascent suffered from this issue, the frequency of complaints makes it a red flag for buyers.

Infotainment and Electrical Glitches

The 2019 Ascent’s Starlink infotainment system was another weak point. Owners reported frequent freezing, slow response times, and Bluetooth connectivity issues. Some even experienced complete system reboots while driving—a serious distraction and potential safety hazard.

Electrical problems weren’t limited to the infotainment screen. Some drivers noticed flickering dashboard lights, malfunctioning climate controls, and issues with the rearview camera. These glitches often required dealership visits and software updates, adding to the frustration of owning a brand-new vehicle.

Safety Concerns and Recalls

The 2019 Ascent was involved in several recalls, including one for improperly secured seat belts and another for a potential fuel pump failure that could cause the engine to stall. While recalls are common, the number and severity of issues in the first year raised concerns about build quality and oversight.

Despite these problems, the 2019 Ascent still earned high safety ratings from the IIHS and NHTSA. But safety scores don’t tell the whole story—reliability and owner satisfaction matter just as much.

Should You Buy a 2019 Subaru Ascent?

If you’re set on a 2019 model, proceed with extreme caution. Look for one with a full service history, low mileage, and evidence of oil consumption checks. A pre-purchase inspection is a must. Even then, be prepared for potential repairs and the possibility of ongoing issues. For most buyers, it’s safer to skip this year altogether.

The 2020 Subaru Ascent: Slightly Better, But Still Risky

The 2020 Subaru Ascent showed improvement over its predecessor, with Subaru addressing some of the 2019 model’s most glaring issues. However, it’s still considered one of the Subaru Ascent years to avoid if you’re looking for maximum reliability.

Ongoing CVT and Transmission Issues

While the 2020 model received software updates to improve CVT performance, many owners still reported shuddering and hesitation. The problem wasn’t as widespread as in 2019, but it remained a common complaint. Some drivers also experienced delayed shifting and rough gear changes, especially in cold weather.

Subaru continued to release updates, but the underlying design of the CVT remained the same. This meant that even with improvements, the transmission was still prone to wear and failure over time—especially if maintenance was neglected.

Engine Stalling and Rough Idling

A new issue emerged in the 2020 Ascent: engine stalling. Some owners reported their SUVs shutting off unexpectedly at stoplights or while idling. In most cases, the vehicle would restart, but the problem was alarming and potentially dangerous, especially in traffic.

Investigations pointed to a faulty fuel pump or sensor, and Subaru issued a recall for certain vehicles. However, not all affected Ascents were included, leaving some owners to deal with the issue out of pocket. Rough idling and hesitation during cold starts were also common, often linked to the same fuel system problems.

Infotainment and Software Bugs

The 2020 model’s infotainment system was slightly more stable than the 2019 version, but glitches still occurred. Freezing screens, unresponsive touch inputs, and Bluetooth dropouts were frequently reported. Some owners found that a hard reset helped, but the problem often returned.

Subaru released over-the-air updates for some models, but many owners had to visit dealerships for software patches. This added inconvenience and downtime, especially for busy families relying on their SUV for daily commutes and road trips.

Is the 2020 Ascent a Safe Buy?

The 2020 Subaru Ascent is a step up from 2019, but it’s still not the most reliable choice. If you find a well-maintained example with low mileage and a clean service record, it might be worth considering—especially if the price is right. But for peace of mind, most experts recommend skipping this year in favor of newer models.

The 2021 Subaru Ascent: A Turning Point

The 2021 Subaru Ascent marked a significant improvement in reliability and owner satisfaction. Subaru had time to refine the design, address early complaints, and improve manufacturing quality. While not perfect, the 2021 model is generally considered a safe bet—especially compared to its predecessors.

Reduced Oil Consumption Issues

By 2021, Subaru had made changes to the engine design, including updated piston rings and improved oil control. As a result, oil consumption complaints dropped dramatically. Most owners reported normal oil levels between changes, and the need for frequent top-offs became rare.

That said, some 2021 Ascents still experienced minor oil burn, especially in high-mileage examples. Regular oil checks are still recommended, but the problem is no longer a widespread concern.

CVT Performance Improvements

The 2021 model benefited from further CVT software updates, resulting in smoother acceleration and fewer shuddering incidents. While the transmission still isn’t as responsive as a traditional automatic, most drivers found it acceptable for daily driving.

Maintenance is key—CVT fluid should be changed every 60,000 miles to prevent wear and overheating. Skipping this service can lead to premature failure, even in newer models.

New Issues: Rear Differential and Suspension

As the Ascent aged, new problems emerged. Some 2021 owners reported a whining or grinding noise from the rear differential, especially during acceleration or deceleration. In some cases, the differential required replacement—a costly repair that could exceed $2,000.

Suspension components, including struts and control arms, also showed signs of premature wear. This was more common in vehicles driven on rough roads or used for towing. Regular inspections can help catch these issues early.

Is the 2021 Ascent Worth Buying?

Yes—with caveats. The 2021 Subaru Ascent is a solid choice if you find one with good maintenance records and low mileage. It’s more reliable than 2019 and 2020 models, and many of the early issues have been resolved. Just be sure to have it inspected by a mechanic, especially the rear differential and suspension.

The 2022–2024 Subaru Ascent: The Best Years to Buy

If you’re looking for the most reliable Subaru Ascent years, the 2022–2024 models are your best bet. These vehicles benefit from years of refinements, improved build quality, and fewer reported problems. They represent the mature phase of the Ascent’s lifecycle.
