Volvo XC60200K250K$328
Ford Escape150K250K $272

The Acura RDX and Toyota Highlander have an expected lifespan of over 300,000 miles if well cared for, but these are on the higher end of the spectrum for mid-size SUVs.

The Audi Q5 and BMW X3 tend to be less durable, with their lifespans hovering around 175,000 miles before major repairs are needed. The Mazda CX-9 lands between these two vehicles with an estimated lifespan of around 200,000 miles when properly maintained.

Which model years of Mazda CX-9 are not reliable regarding longevity?

The Mazda CX-9 was first released in 2007, and since then, there have been a few model years that are not as reliable regarding longevity. 2008, 2010, 2011, and 2012 models of the CX-9 are notorious for having transmission problems, and even if they were properly maintained, the transmission could still fail. In addition, some owners have reported that the engine mounts and spark plugs can wear out prematurely in these model years.

The 2013 Mazda CX-9 improved reliability in certain areas, but there are still some reports of transmission issues with this model. The 2014-2015 models have improved slightly from the earlier versions and are more reliable. However, they have been known to have electrical issues due to faulty wiring harnesses.

Overall, we can say that the first-generation Mazda CX-9 (2007–2015) tend to be less reliable compared to later generations (2016–present). That said, if you own a second-generation CX-9 (2016–present), you can expect it to provide dependable service for many years—provided that it’s properly maintained.
