Launched in 2007 the CX-9 is a 3 row, 7 passenger SUV from Japanese automaker Mazda.
Through its two generations of production, it has won over many families thanks to its ample space, lively performance and abundance of style.
If you’re considering purchasing a CX-9 you might be wondering about its average lifespan.
We’ll cover that in this article, read on to find out…
Here is the short answer to how long Mazda CX-9 last:
The Mazda CX-9 is a robust SUV that can last between 200,000 – 250,000 miles on average when properly maintained, driven conservatively and well looked after. Based on an annual mileage of 15,000 miles, it can last 13 to 17 years of service before breaking down or requiring uneconomical repairs.
How Many Miles Can You Expect from a Mazda CX-9?
The CX-9 is a highly durable full-size SUV.
This model is regarded as one of the most dependable vehicles on the market today and has received glowing reviews from owners, car experts and auto journalists alike.
In their most recent annual reliability survey, Consumer Reports named Mazda’s new cars as the most reliable in the world, and the CX-9 is ranked the most reliable in its segment according to Repair Pal.
There are many reports of satisfied owners that have breezed past the 100,000-mile mark in their CX-9 with little more than following Mazda’s recommended service intervals.
We even encountered owners with over 250k miles although they are in the minority and these types of mileages shouldn’t necessarily be expected.
For the most part, a well-kept CX-9 can certainly last 200,000 – 250,000 miles however this will require work on the owners part.
After accumulating high miles big-ticket items have a much greater chance of failure such as the engine or transmission – when that happens the car costs more to fix than it is worth.
The life expectancy of your CX-9 will be cut short if you avoid:
- Service appointments
- Routine oil changes
- Tire rotations
- Using quality parts
- Driving smoothly
As a general rule, the newer CX-9 models are expected to last longer due to advances in design and quality.
Do Mazda CX-9 Rust Easily?
The modern-day Mazda CX-9 does not rust easily and is generally considered to be quite rust resilient, across owner forums CX-9 rust complaints are rare. However, Mazda did recall nearly 200,000 CX-9 SUVs from the 2007 – 2014 model year due to the front suspension ball joints being susceptible to rust.
In recent years Mazda has shaken off their reputation for cars that rust easily thanks to advances in rustproofing technology.
Rust on a new CX-9 is out of the ordinary and should you experience any issues your first port of call should be your Mazda dealership.
Residents of cold-weather states that aggressively salt the roads in the winter should take extra precautions though, as salt can drastically accelerate rusting.
Similarly, those living by the coast where salt in the air is prevalent should also be mindful.
Owners residing in drier, hotter states such as Arizona are far less likely to experience rusting issues – although paint fading is more common.
Tips to keep your CX-9 rust-free:
- Regularly wash and dry your car: This includes its underside (especially during the winter) to remove the salt, dirt and grime that causes rust. We recommend having a detail-shop wash everything underneath at the end of each winter.
- Repair paint damage and scratches: Exposed metal will oxidize. If it’s beyond a DIY fix speak to your local body repair shop.
- Garage: Store your CX-9 in a garage to protect it from harsh weather and bird droppings.
- Waxing: Wax your car twice a year. Not only will this make your CX-9 look amazing, it also gives a protective coating against rust.
- Rustproofing: If you’re planning on keeping your CX-9 well past it’s warranty you might want to consider a rustproofing treatment, popular choices are Krown and Rust Check.
- Ceramic Coating: A popular choice for those who want to add an extra layer of protection to the paint job.
Mazda offers a 5-year/unlimited mileage limited warranty against corrosion perforation for CX-9 models.
What is High Mileage for a Mazda CX-9?
A Mazda CX-9 with over 120,000 miles is considered high mileage, and a riskier investment although there are many factors to take into account, primarily the vehicle’s maintenance history, its overall condition and number of previous owners.
Buying one with over 120,000 miles won’t necessarily equate to a sour outcome.
A well-maintained CX-9 with 120,000 miles might be a better purchase than one with 80,000 miles that had lots of owners and led a rough life or was previously a rental car.
When buying a second-hand CX-9, consider the following:
- Maintenance history. Check that the car was properly serviced and the owner can provide evidence of this.
- Get a second opinion. Take it to an independent auto diagnostic clinic or have it inspected by a mechanic.
- Check the CarFax. This doesn’t guarantee anything but it will provide a clearer picture of wear-and-tear. Ensure it has minimal damage, if any. Review the information to make sure if something happened such as engine- or transmission-related.
- Number of previous owners. As a general rule, less is better. More owners usually means more wear-and-tear. If one family owned it and drove the full mileage and serviced the car, then you can almost guarantee they took good care of it throughout their ownership.
- How long you are planning on keeping the car. If you’re planning on keeping the car for a long time, you should evaluate whether the short-term savings outweigh spending a bit extra on something more reliable.
If the car has averaged a lot more or less than 10,000 to 15,000 miles per year, you might want to further investigate why – for example – a 4-year-old model that has 100,000 miles.
