Read on to find out more about the Subaru Ascent’s expected average lifespan

Here is the Short Answer to How Long Subaru Ascent Last:

The Subaru Ascent is a robust SUV that can last between 200,000 miles and 250,000 miles. This means with an average of 15,000 miles driven per year, you can expect the Ascent to last around 13 – 17 years. This is dependent on proper maintenance and good driving habits.

How Many Miles Can You Expect from a Subaru Ascent?

By our estimates, and in comparison with other vehicles manufactured by Subaru, the Subaru Ascent can last between 200,000 and 250,000 miles, with proper care and maintenance.

Not much data is provided with regard to the longevity of the Subaru Ascent. This is understandable since this is a newly released vehicle, having been in the market for just about 3 years. 

According to driving tests conducted by, in which they drove a Subaru Ascent for up to 40,000 miles, they claimed that there were no major issues, and that they only had to make unscheduled maintenance trips to the service center three times.

Based on Subaru’s track record, we expect the Subaru Ascent to comfortably make the 200,000 mile mark.

According to a study conducted by, 97% of Subaru vehicles that were sold in the past decade are still performing on the road today.

Some owners have even reported reaching 300,000 miles with their Subaru, especially the Outback and Forester models – we would expect the Ascent to perform much the same.

Hitting these types of numbers will require meticulous maintenance and should not necessarily be expected.

It must be noted, however, that our expected lifespan is only an approximation, as there are several factors that still need to be considered that may prolong or shorten lifespan, including how it is driven and how well it’s looked after.

How Soon Should You Expect Rust on a Subaru Ascent?

Across three generations of Subaru Ascent models, and over 185,000 units sold in the US, there have relatively few complaints regarding rust.

A few Subaru Ascent owners have reported rust concerns in the undercarriage of their models.

By our estimates, you could expect your Subaru Ascent to have some degree of corrosion in four to five years, however this can vary based on factors such as:

  • Exposure to road salt (road salt combined with moisture leads to corrosion)
  • Humidity (amount of moisture in the air)
  • Salt in the air (coastal regions are notorious for vehicle rusting)
  • Where the vehicle is stored (parking in a garage reduces exposure to the elements)
  • How often the vehicle is washed (dirt can trap moisture which can lead to corrosion)

Subaru offers a 5-year corrosion warranty for all its modern vehicles, including the Subaru Ascent.

However, this only applies if rust and corrosion are detected inside the panels or metal sheets, not just surface rust.

Here are a few tips to reduce the chances of rust and corrosion:

  • Wash your vehicle regularly, including the undercarriage.
  • Buy a high-quality car cover, especially if the car is typically parked outside.
  • Apply rust proofing sprays or invest in a ceramic coating
