What Infiniti QX50 Years Should You Avoid?

Now that we know the most reliable Infiniti QX50 models, how about the worst ones? We have curated a list of the QX50 models that you should avoid below.

Let’s get into it, shall we?

4.  2010 Infiniti QX50 (EX35)

The 2010 Infiniti QX50 is one of the not-so-great QX50 models, especially in terms of the number of issues.

On Car Complaints, it has a total of 5 reported problems, and two of these issues occupy the first and second spot on the list of worst EX35 problems.

One of its worst problems is the steering lock issue, which costs thousands of dollars to fix. It also has a coating issue, which, according to one owner, looks really horrible. 

It, however, manages a 76/100 customer rating on J.D. Power, all thanks to its lively acceleration, dashboard styling, and navigation system. On the flip side, the 2010 QX50 also suffers poor forward visibility and bad second-row seats. 

Talking about poor visibility, you might be interested in learning about SUVs with the most blind spots.

While it isn’t a terrible vehicle overall, you might want to avoid this and go for less problematic models.

5. 2015 Infiniti QX50

The 2015 Infiniti QX50 is ranked as the worst model by Car Complaints, even though it has fewer complaints than a couple of other models.

The model suffers premature rotor wear, which is ranked as the worst Infiniti QX50 problem. This problems occurs at an average mileage of 18,000 miles and costs about $500 to fix. 

Owners also complain about poor rear visibility and bad seating in the second row. However, it does have a few great attributes including great acceleration and an improved audio system.

Overall, the 2015 Infiniti QX50 isn’t a terrible car, it just happens to have one of the worst problems in the model’s history. That alone might be enough reason to avoid and go for more reliable models. 

6. 2016 Infiniti QX50

The 2016 Infiniti QX50 has a total of 4 reported issues on Car Complaints.

The most notable issue is the swamped ICU unit, which costs nearly $2,000 to fix, according to a complainer. The average mileage for this issue is 32,000 miles, which is why it ranked as one of the worst issues. 

Interestingly, besides this disconcerting issue, the 2016 Infiniti QX50 is great in most other departments. Owners and critics have praised its acceleration, improved audio system, and simple folding mechanism for the rear seats. 

If a swamped ICU isn’t something you want to risk dealing with, you might want to avoid this model. 

7. 2019 Infiniti QX50

The 2019 Infiniti QX50 has the highest number of complaints of all QX50 models on Car Complaints with 5. That’s even more concerning when you realize it is one of the most recent models on the platform.  

Three of these issues are engine problems, two of which have a serious severity rating of 10.0. There were also complaints about the model’s front suspension, which reportedly involves serious knocking and rattling. 

Car and Driver gives it a measly 6/10 rating owing to its unimpressive fuel economy and noisy engine amongst other issues. In all fairness though, its cabin is more comfortable than previous model years. 

Overall, the 2019 Infiniti QX50 is one of the worst QX50 models, and while it’s not all terrible, we advise avoiding it entirely. 

8. 2021 Infiniti QX50

The 2021 Infiniti QX50 closes out our list of the worst QX50 models to avoid and we are about to see why. While it’s not listed yet on Car Complaints, the model caught a lot of flak for some very serious issues.

According to Consumer Reports, the 2020 QX50 model has issues with body hardware, in-car electronics, and power equipment. That explains why it got bad reliability and owner satisfaction ratings on the famed platform. 

If you are looking to buy a recent luxury compact crossover, we advise going for better options than the 2021 Infiniti QX50.

Side Note: The Infiniti QX50 models from 2008 to 2013 were known as Infiniti EX35 as we have dutifully indicated in the article.

Additionally, as you have probably noticed, the Infiniti QX50 generally had very few reported issues on Car Complaints and other such platforms.

This is most likely a result of its “luxury” status, which means low production output and low sales. For some context, the Infiniti Q50 sold a total of 19,196 units in 2021.
