What are the Common Problems with Infiniti Cars?

When it comes to luxury vehicles, Infiniti is a household name that is synonymous with style, comfort, and performance. However, like all car brands, Infiniti models have their share of common issues that necessitate an occasional visit to an Infiniti service center.

This article seeks to provide a comprehensive understanding of some of the most frequently reported problems with different Infiniti models, along with the solutions offered by Infiniti repair services.

An Overview of Infiniti and Its Reputation for Reliability

Infiniti is a luxury vehicle division of Nissan, known for delivering reliable vehicles. However, it’s important to understand that no car is entirely free from problems. As the car ages, the likelihood of needing repairs increases. To help you prepare for potential repair costs, it’s beneficial to know the common issues that your specific Infiniti model may develop.

On the bright side, Infiniti generally receives average ratings from experts regarding reliability. J.D. Power often recognizes Infiniti models for their reliability, and Repair Pal awards Infiniti a respectable 3.5 stars out of 5 for reliability. According to Repair Pal, the average annual repair cost for Infiniti models is roughly $638, which is slightly less than its average across all models.

Identifying the Most Common Infiniti Problems

Although Infiniti cars are generally reliable, they do have some commonly reported problems. Here, we’ll list some of the most frequently reported issues that may require you to visit an Infiniti garage.

Continuously Variable Transmission (CVT) Problems

A common issue with Infiniti vehicles is problems related to the Continuously Variable Transmission (CVT). Infiniti uses this type of transmission due to its ability to provide smoother acceleration and improved fuel efficiency. However, CVT problems can lead to the car not responding to accelerator inputs or jerking when driving.

Airbag Recalls

Infiniti vehicles have also faced various recalls due to airbag issues. The most notable of these is the Takata airbag recall, which affected numerous car manufacturers worldwide. The problem with these airbags is that they have the potential to explode when deployed, causing serious injury.

Crankshaft Angle Sensor Failures

Another common issue among Infiniti models is the failure of the crankshaft angle sensor. This sensor monitors the crankshaft’s rotation speed and position, sending this data to the car’s computer system. If this sensor fails, it can cause issues with the vehicle’s engine performance, including stalling or failing to start.

Notable Infiniti Models and Their Issues

Now, let’s take a closer look at some specific Infiniti models and the common problems associated with them.

Infiniti G37

The Infiniti G37, particularly the 2009 model, has been known to experience issues with the passenger airbag warning light. This light would often illuminate without cause, leading drivers to question the airbag’s functionality in the event of a crash. The average annual repair cost for the G37 is estimated to be around $540.

Infiniti G35

The 2003 Infiniti G35 model has had the highest number of recalls and complaints. The main problems reported for this model include fuel filler hose cracking, crank and cam position sensor weld issues, and exterior lighting problems. The average annual repair cost for the G35 is around $476.

Infiniti FX35

First-generation Infiniti FX35 models have a unique problem of melting dashboards, which is not only unsightly but can also cause visibility issues due to the glare it creates. The average annual repair cost for the FX35 is estimated at $617.

Infiniti Q50

The 2014 Infiniti Q50 model has the highest number of recalls and complaints, with issues related to unexpected vehicle acceleration, steering, and airbag deployment. The average annual repair cost for the Q50 is estimated at $648.

Infiniti QX56

The 2008 Infiniti QX56 model had a recall related to faulty airbags. Other complaints include cracked radiators, fuel system problems, and transmission issues. The average annual repair cost for the QX56 is estimated at $807.

Infiniti Iniouch Lawsuit

Another notable issue that Infiniti faced was related to their InTouch infotainment system. A lawsuit filed in 2014 claimed that the system required an app for software upgrades, but the app wasn’t available for over a year. While the lawsuit was not granted class-action status, Nissan offered settlements to the affected owners.

Infiniti Service: Addressing the Issues

Fortunately, most of these common Infiniti problems can be addressed at any authorized Infiniti service center. These centers are equipped with state-of-the-art facilities and trained technicians who understand the intricacies of Infiniti vehicles. So, whether it’s a minor issue with the infotainment system or a major transmission problem, an Infiniti garage can provide the necessary repairs.


While Infiniti vehicles are generally reliable, they do have their share of common problems. As an owner, it’s important to be aware of these issues and get them checked at an authorized Infiniti service center to ensure your vehicle’s longevity. Remember, preventative maintenance is always better than costly repairs down the line.
