With so many models to choose from, it can be difficult to decide which one to buy and which to hold out on? This is why I will be talking about the best and worst years for Mazda CX-9.

What Are The Worst Years For The Mazda CX-9? Which Years To Avoid

Here are the top 5 models of the Mazda CX-9 that you should avoid at all costs. These models are known for their major and sometimes life-threatening issues.

1. 2012 Mazda CX-9

Most car problems are an annoyance and, at worst, only prevent the car from starting, but in the case of the 2012 Mazda CX-9, one of the major problems can put your life at risk.

The greatest issue you could face with this model is the brake booster unit failing.

This would make it quite difficult for the car to engage the brakes. Along with this, the braking time of the car would also increase significantly.

You can see why this can put you and any passengers in the car at risk, which is why it takes the top spot on this list.

While many of the other models in this section of the article will display the same problems, they are much fewer in number than this model.

This 2012 model had it the worst, which is why it deserves to be at the top of the list of worst models of the Mazda CX-9.

2. 2010 Mazda CX-9

If you think the 2012 model was the only one to have the brake boost unit problem, then you are mistaken, as the 2010 Mazda CX-9 model also has this issue and a variety of other issues.

Even though the brakes are integral, you cannot apply them if your car does not start in the first place.

This model of the Mazda CX-9 had issues with the water pump, which caused it to fail.

In turn, that issue would lead to the engine failing as well. This issue would persist but was mostly associated with this model.

3. 2011 Mazda CX-9

If the models before and after had the issue, it would make sense that the 2011 Mazda CX-9 would also have the brake boost unit issue.

This is a huge oversight when it comes to Mazda as to how they could allow this major problem to persist for such a long time.

Aside from this major problem, the 2010 Mazda CX-9 also had many other engines and drive train issues.

These issues were few and far between, which is why this model only gets the 3rd spot on this list.

4. 2008 Mazda CX-9

One of the earlier models of the lineup, the 2008 Mazda CX-9, was not a good successor to the original Mazda CX-9, which is mainly why it gets 4th place on this list.

It had a wide range of engine issues and standard braking problems that people had to deal with.

The water pump failure dates back to this model, which, as I have discussed, would cause the engine to eventually fail.

The brakes had a stiff pedal, and premature brake wear was common. Along with that, the engine also had issues with the ignition coil.

5. 2013 Mazda CX-9

Another year the Mazda CX-9 featured the dreaded brake boost issue, which caused a lot of backlash from the community.

The 2013 Mazda CX-9 model was a clunker but made good on various improvements, which is why it only gets last place on this list.

Water pump and engine failure are common trends when talking about the Mazda CX-9.

This, along with the brake boost unit failing, makes it such that the entire list is ordered on which model had it the worst.

What Are The Best Years For The Mazda CX-9? Which Years To Buy

Now that I have discussed everything from failing engines to water pumps, it is time to discuss the best models of the Mazda CX-9 lineup.

These models are where the magic happens and are the ones that should be on your radar at all times.

1. 2018 Mazda CX-9

Starting off this section, I present the 2018 Mazda CX-9. This model takes first place on this list because it has virtually no complaints.

This particular model came with a very powerful engine for passing and presented itself with excellent handling. The model was available in 4 different trims.

Bring more active safety features into the fray, and featuring seven seats, the car was available in AWD & FWD.

It came to the market and was universally loved by fans of the lineup and car enthusiasts. This is also why it boasts such high scores on various lists.

Aesthetically, the 2018 Mazda CX-9 can be hit or miss, but for many, the design choice is very nice and adds to most Japanese cars’ luxury.

While it is missing a few features, they are by no means crucial to the car, which is why it can still claim the top spot.

2. 2021 Mazda CX-9

While it added a lot more to the table, it also came with a few negatives, which is why the 2021 Mazda CX-9 model takes second place on this list.

The car features amazing handling similar to the 2018 model but with a much more responsive drive train.

The year added another trim into the mix, increasing the total number of trims to 5.

Depending on the trim, you could get your hands on a luxurious interior. This would only be available in the signature trim.

The turbo four-cylinder engine, 10.25-inch screen, AWD, and FWD were all available in all trims.

3. 2020 Mazda CX-9

While the 2021 model was impressive, to say the least, it was a derivative improved upon the 2020 Mazda CX-9.

This model featured the same improvements to the drive train and handling, which is now synonymous with the lineup. It also had adaptive cruise control, which worked flawlessly.

The model had one less trim than the 2021 Mazda CX-9 but featured its group of new active safety features, which were standard.

Among the various features added were heated front seats which were also standard. Despite all of this, the 2021 Mazda CX-9 is better, which is why this model is below it.

4. 2019 Mazda CX-9

Many people were expecting great things from the 2019 Mazda CX-9, especially since it was coming off the praise of the 2018 model.

While it could not live up to the hype surrounding it, the 2019 Mazda CX-9 was still able to wow the crowd with its stellar handling and drivetrain.

It made the turbo four-cylinder engine standard which many regarded as the best engine in the entire lineup.

Additionally, it also brought Android Auto and Apple CarPlay into the fray. It got in a 360-degree camera system as well.

5. 2017 Mazda CX-9

Before the success of the 2018 model, the community was talking about the 2017 Mazda CX-9.

While it was mostly just an improved version of the model before it, the previous model was also quite respectable.

Mazda applied the mentality of “if it ain’t broke, don’t fix it,” which worked.

People appreciated the improvements to the interior, especially when it came to the multimedia system.

While little changed elsewhere, the 2017 Mazda CX-9 model still provided a spectacular driving experience far better than its competition at the time.

It is a great model but pales compared to the rest, which is why it takes last place.

How Reliable Is A Mazda CX-9?

According to various consumer reports, you will find the Mazda CX-9 to be quite reliable.

Many of these reports have gone up to an 80% approval rating, while the recent models of the Mazda CX-9 have even gotten a perfect score.

This should be more than enough to give you an idea about how reliable the Mazda CX-9 is, but if you are not convinced, let me elaborate.

Along with boasting great scores, it also ranks well above its competition in mid-sized SUVs and has a lower repair cost in its body type range.

How Long Do Mazda CX-9 Last?

A typical Mazda CX-9 should last around 200,000 and 250,000 miles.

This is a very good amount for mid-sized sports utility vehicles as it allows you at least 13 to a little over 16 years of service, assuming you drive 15,000 miles a year.

You can bump this life considerably or decrease it by a lot; I will talk about this in the next section of the article.
