The luxury sedan segment may not be as popular as it was a decade or so ago, but it’s still a compelling class due to the numerous sporty sedans available. Offerings such as the Audi A4 and the BMW 3-series are excellent options if you want exhilarating performance and pure driving dynamics to make your day. With that said, one model that’s worth checking out is the Infiniti Q50 luxury sports sedan.

The Infiniti Q50 is praised for its gorgeous bodywork, smooth and satisfying engines, and good value for the money. While it doesn’t come close to segment competitors like the BMW 3 Series, the Q50 offers decent driving dynamics and enjoyable handling for demanding drivers. So is the Infiniti Q50 worth buying as used?

When buying used, you have to take long-term reliability into account. Like all vehicles, not all Infiniti Q50 years are created equal, and some models are simply more reliable than others. So for today’s post, we compiled the worst Infiniti Q50 years to avoid and which ones you should consider buying used. Let’s take a look.


You’ll only want to spend your money on the most reliable Infiniti Q50 year you can. If you don’t know what that year is, keep reading; we’ll break down the answer to this question and more.

Which Infiniti Q50 Years To Avoid?

According to RepairPal, the Infiniti Q50 has a reliability rating of 4.0 out of 5.0, an Above Average score. This puts the Q50 in the 10th spot of the most reliable luxury midsize cars. Thus, buyers looking for a luxury midsize sedan that doesn’t require much maintenance should consider the Infiniti Q50. Having said that, below are the worst Infiniti Q50 years to avoid:

  • 2014 Infiniti Q50
  • 2015 Infiniti Q50

2014 Infiniti Q50

Debut models are generally prone to reliability issues, and the 2014 Infiniti Q50 is no exception. When the 2014 Q50 was released, it didn’t exactly light the market on fire. Nevertheless, the Q50 was praised for its potent V6 engine and upmarket cabin quality. Unfortunately, the Q50 also happens to be the worst model in terms of reliability.

Warped Brakes

According to, the 2014 Infiniti Q50 has received 21 complaints, and its most common issue is the warped brakes. Frustrated owners were forced to prematurely replace their brake rotors and pads due to warped brakes. A user from New York wrote:

Brakes were warped after being cut twice. Sport brakes were terrible..they tried to fix the issue. The only way was to replace the brakes. They also make horrible groaning noises sounded like a rusty swing set.

In other cases, drivers also experienced various symptoms like squeaking noises, excessive vibrations, and grooves from the rotor. We highly recommend checking this Q50 model year for warped brakes before considering it for purchase.

Steering Issues

The Q50 offered various driving features for a more engaging ride, and one of the most notable ones was the Direct Adaptive Steering System (DAS). The DAS was designed to streamline the steering mechanism for precision driving, but it became a trouble spot for the Q50. It was Nissan’s attempt at autonomous driving capabilities, but it fell flat on its face in the Q50.

According to various reports, the DAS can cause multiple problems during startup and may lead to decreased responsiveness and turning radius. Apparently, the DAS was also known to disable the electronic steering system when the temperature dropped.

As a result, this steering issue has forced Nissan to recall 60,000 Q50 sedans. According to Nissan representative Stefan Weinmann:

That system could malfunction “in certain rare circumstances, just after starting the vehicle” when a software glitch “can lead to a lack of steering responsiveness and change in turning radius,”

This issue shouldn’t be much of a deal breaker since the steering troubles were fixed by reprogramming the steering ECU software.

2015 Infiniti Q50

The 2015 Infiniti Q50 is much more reliable than the debut model – but it has its fair share of issues that make it hard to recommend. Two of the most common problems of the 2015 Q50 are:

Premature Tire Wear

A few owners of this midsize sedan claimed they had to replace their tires due to premature wear. According to a user from Philadelphia:

Went through 5 tires in 2 years. These tires cannot handle any potholes. I have 3 other cars in the house and none of the other cars have this issue. The roads are bad in Philadelphia but they are not bad enough to go through 5 tires.

This reliability issue was particularly frustrating because it’s a low-mileage issue at around 12,100 miles. Thankfully, this issue was covered by warranty. 


Buying a used or CPO luxury car is one of the smartest buys you can make - you can get a lot of car for not much money. You can pick up a three-year-old luxury car for about half of what you’d pay new. Check out this list of the best used luxury cars on the market to find the best deals. 

Brake Issues

Although less prevalent, the 2015 Infiniti Q50 also struggled with brake issues like the debut model. According to the reports, the Q50’s brake rotors were prone to warping, which accelerated the wear and tear of the brake pads. Frustrated drivers had to replace their brake pads a lot sooner than expected. One user wrote:

Started to detect a light vibration while braking at around 4,500 miles, took it to my dealer to get it checked out. Service Adviser told me that because of how I drive, the rotors are warped and would require resurfacing. Advised him that my commute is less than 7 miles each way to work and that there is absolutely no stop/go city traffic in my suburbs at that time of night.

While brake rotors may warp over time because of wear, it certainly is not normal for them to happen at such low mileage. This makes the 2015 model one of the worst Infiniti Q50 years to avoid.

Which Infiniti Q50 Years To Buy?

The 2019 and 2020 Q50 models are the most reliable for the current lineup. The 2019 Q50 received good reliability feedback from critics and customers alike. According to J.D. Power, the 2019 Infiniti Q50 scored 82 out of 100 in Quality & Reliability. Consumer Reports also rated the 2019 Q50 with a high score of 4.0 out of 5.0 for reliability.

Meanwhile, the 2020 Q50 also scored high marks in reliability. J.D. Power gave the 2020 model year a respectable reliability score of 81 out of 100, which is rated Great. It’s a solid pick for a used luxury midsize sedan.
