But how does it fare in terms of reliability?

JD Power gives the Q50 a “Great” reliability rating of 83/100, while it’s a Below Average rating of 6.4 Edmunds, citing the model is showing its age, especially compared to newer and more affordable sedans.

When it comes to keeping Infiniti Q50 in top shape, its maintenance costs are lower than most luxury midsize models, at around $650 annually, according to RepairPal. It’s also less likely to undergo severe repairs at 8%, compared to 12% for luxury midsize vehicles.

What Are the Most Common Issues with Infiniti Q50s?

While the Infiniti Q50 is not usually one of the first that come to mind when talking about reliable cars, relatively few issues have been reported throughout its decade-plus in production—although there have been several recalls with specific model years.

Warped Brakes

Some model years of the Q50 were reportedly prone to warping brakes, resulting in a loud groaning noise when stepping on the brakes. Replacing both the brake rotors and the brake pads usually fixes this issue.

Affected Model Years:

Steering Issues

The direct adaptive steering system can develop errors while the vehicle is being started. This anomaly changes steering response and turning radius, making the vehicle suddenly very difficult to control. This is covered by a recall where the system is reprogrammed, but if the recall hasn’t been done, it can be an issue.

Affected Model Years:

  • 2014
  • 2015
  • 2016

Driveshaft Failure

Several model years of the Q50 along with other Nissan vehicles were issued a recall due to the driveshaft being prone to breakage. This can lead to significant power loss and the vehicle rolling away when the parking brake isn’t applied. Nissan has instructed dealers to replace affected driveshafts free of charge.

Affected Model Years:

  • 2014
  • 2015
  • 2016
  • 2017

  • 2018
  • 2019

Defective Steering Components

A recall has also been made for certain Q50, QX50, and QX60 model years for a defective front steering knuckle and rear axle housing. These components have been known to deform upon impact, such as hitting a curb, which can lead to loss of steering control or wheel separation. Dealers will check and replace any affected components for free, as necessary.

Affected Model Years:

Malfunctioning Engine Control Module

The engine control module (ECM) in some Infiniti Q50 and Q60 models have been reported to reduce engine power and restrict fuel supply to the engine when it detects rapid acceleration. This may cause the engine to stall and increase the risk of a crash. Dealers have been instructed to reprogram the ECM to resolve this issue free of charge.

Affected Model Years:

FAQ

Are Infiniti Q50 vehicles expensive to insure?

The Infiniti Q50 can be expensive to insure for several reasons. First, luxury cars like the Q50 generally cost more to insure because of the high purchase price and specialized labor needed for repairs and maintenance. Its luxury status also makes it especially prone to theft, which insurance companies factor into premiums.

How long does the Infiniti Q50 last?

Infiniti and Nissan vehicles in general have been known for their longevity and the Q50 is no exception. With proper driving habits coupled with regular maintenance, the Infiniti Q50 can last 200,000 miles or 20 years, although there have been reports of vehicles passing the 300,000-mile mark. In comparison, most luxury vehicles have an average lifespan ranging from 200,000-250,000 miles.
