Having a similar design based on the Infinity Essence, the Infiniti Q50 made its debut in the 2013 Canadian International AutoShow and wowed the audience but left a lot of room for car enthusiasts to speculate about the reliability and durability of the car.

People’s main concern with this new lineup was “How long do Infiniti Q50 last?”.

This and all other concerns would later be squashed when it was discovered that the vehicle could easily last an average of 250,000 miles and had the capability of reaching 300,000 miles if given proper upkeep.

This would, however, not be enough to please fans who were skeptical of these statistics as many things go into determining the car’s lifespan, and a lot of things can go wrong.

For this reason, I will be taking a close look at the Infiniti Q50 and see the car’s capabilities and how long it can last compared to other vehicles.

What Is The Average Life Expectancy Of An Infiniti Q50?

Does an Infiniti Q50 last long? Let's find out

Seeing the minimum and maximum mileages that you can get with your Infinity Q50, it should be clear that you can easily get a minimum of 13 years with the vehicle if you abuse it regularly.

Moreover, being a responsible owner who takes care of the vehicle can lead to a significant boost in the lifespan of the car which results in it lasting for upwards of 20 years which is extremely competitive against high-end luxury cars currently available in the market.

On average, it should easily last you 250,000 miles or 16+ years which is, in some cases, the maximum life some vehicles can reach, making the Infinity Q50 a very long-lasting and reliable vehicle that you should consider.

Does Infiniti Q50 Last Longer Than Other Similar Vehicles?

Having such a long-lasting nature and a reliable reputation across the community, it is fair to say that the Infinity Q50 is a really good vehicle that honors its reputation as a luxury vehicle.

However, many people do not know how it compares to other vehicles that are found in its class which is why, in this article, I will be directly comparing the Infinity Q50 to other well known and prominent luxury midsized vehicles so that you know how reliable and long-lasting the Infinity Q50 can be.

For this experiment, I will be checking various aspects and qualities of the vehicles that affect their lifespan and reliability to see how the Infinity Q50 can compare to this bunch.

1. Infiniti Q50 Vs. Acura TLX

The first car I will be comparing with the Infinity Q50 is the Acura TLX, one of the best and most highly respected midsized luxury vehicles on the market.

  • Going up against a highly rated car, the Infinity Q50 is slightly less reliable than the Acura TLX, which is consistently regarded as one of the best of its class.
  • Both the Infinity Q50 and the Acura TLX have the same relative lifespan and can reach 300,000 miles.
  • When it comes to problems and complaints, the Infinity Q50 is much less prone to issues than the Acura TLX, which had most of its problems scattered in its first model.
  • The maintenance and repair costs of the Infinity Q50 are exponentially more expensive than the Acura TLX, which is $200 cheaper than it’s the average vehicle which is already $100 cheaper than midsized luxury vehicles.

In this first comparison, the Infinity Q50 tries its best and has much fewer issues but still fails to overtake the Acura TLX, which is simply more reliable and cheaper to maintain.

2. Infiniti Q50 Vs. Lexus ES 300h

The next car I will compare to the Infinity Q50 is the Lexus ES 300h, another prominent figure in the midsized luxury market.

  • Like the Acura TLX, the Infinity Q50 cannot beat the Lexus ES 300h, which boasts higher reliability stats throughout various reports.
  • These same reports state that both the Infinity Q50 and the Lexus ES 300h have similar longevity, providing the same maximum service period and lasting the minimum time.
  • Only being one year older than the Infinity Q50, the Lexus ES 300h has much fewer issues when compared to the vehicle, even in its first model, which did considerably well.
  • Things go even further against the Infiniti Q50 as the Lexus ES 300h is much cheaper when compared to both the Infinity Q50 and the average vehicle.

The Infiniti Q50 stood no chance against the Lexus ES 300h, which is simply better than it is in all regards that have been discussed above.

3. Infiniti Q50 Vs. Acura TSX

The final car I will place against the Infiniti Q50 is the Acura TSX, a vehicle with a similar name and reputation as the Acura TLX.

  • Following the same trend as the previous two comparisons, The Infinity Q50 is less reliable than the Acura TSX, which is more reliable across the board.
  • This reliability is further supported by the fact that both the Infinity Q50 and the Acura TSX share the same service period of 250,000 miles to 300,000 miles at max.
  • The Infinity Q50 has been stable mostly throughout the lineup; however, the Acura TSX has seen a lot of problems and issues throughout its many models.
  • Despite the many issues, compared to the Infinity Q50, the Acura TSX is much cheaper to repair and maintain.
    It is clear that the Acura TSX is the winner in this comparison, despite being more problematic than the Infinity Q50.

Still, it matters very little as proper care and treatment can significantly reduce these problems, and even if you do encounter them, they are extremely cheap to repair.

Life Expectancy Of Infiniti Q50 Car Parts

A car is only as reliable and healthy as the components inside it.

If even one part of the car starts to malfunction or break apart, it can lead to serious issues, which can significantly reduce the lifespan of other components and the car itself.

This is why you should make sure to keep extra care of certain parts and components of the Infiniti Q50.

To that end, I will be discussing the different major parts that are found in the Infinity Q50 and tell you how long you can expect them to last before needing a replacement.

I will also provide tips and tricks which will increase the lifespan of these parts a swell.

Average Lifespan Of Infiniti Q50 Brake Pads

The brake pads of the Infinity Q50 can last slightly longer than other vehicles.

They are capable of going up to 65,000 miles at the most, which is 5,000 miles less than other brake pads, which is why their average lifespan is also a bit less than its competitors.

To make sure that you get the best possible lifespan from your brake pads, you must avoid quick starts, city driving, and short trips which involve a lot of braking.

Any braking you should do should also involve engine braking, and you should make sure not to slam the brakes suddenly to avoid extreme wear and tear.

Average Lifespan Of Infiniti Q50 Battery

Most batteries that are found in other vehicles and cars are capable of lasting at most five years and have a minimum of 3 years of usage.

This is the same for the Infinity Q50, which can provide a battery life of up to 75,000 miles and does not offer any improvement from its competitors.

To further extend the battery of the car, make sure it lasts as long as it possibly can, make sure that you protect it from the cold while driving, and have all nonessential applications which use the battery off.

Limit any short rides and regularly clean the terminals of the battery.

Average Lifespan Of Infiniti Q50 Tires

As mentioned above, the Infiniti Q50’s tires have an issue that leads to premature brake wear.

Assuming that this problem does not occur in your particular model, you should be able to get an average of 40,000 miles and at most 50,000 miles if you use them well.

If you want your tires to last as long as possible, you must make sure the tires are regularly inflated and make sure to visit a mechanic regularly so that they can properly balance out the wheels.

Average Lifespan Of Infiniti Q50 Transmission

The transmission of the Infinity Q50 can last just as long as the car itself, which means that you should not feel the need to get a replacement for the car as long as you avoid issues and give the proper transmission care.

This will involve you keeping a lookout for any problems and immediately taking the car to a mechanic if you feel there is a problem in the car.

Avoid grinding the gears, slipping the clutch, and changing the gears at the wrong RPMs.

Average Lifespan Of Infiniti Q50 Spark Plugs

Depending on the model of your Infiniti Q50, your spark plugs life will vary considerably, with the least durable spark plug capping at 45,000 miles and the most durable ones lasting as long as 100,000 miles.

Most will recommend you to replace the spark plugs at 30,000 miles afterward, but if you use higher durability spark plugs, they can last much longer.

If you want to extend how long they can last, then you must maintain the spark gap and regularly clean the mounting area.

You must also use a dielectric compound to coat the insulator and secondary wire.

Average Lifespan Of Infiniti Q50 Key Fob

The key fob of the Infinity Q50 is similar to the key fobs of other vehicles, providing a lot of utility at the same lifespan, lasting 3 to 4 years.

This mostly depends on the battery life of the key fob, which should last you the same amount so long as you do not abuse it.

If you make sure that you use the key fob sparingly, opting to use the key itself to open the car and trunk, the key fob should last much longer than it would normally have.

What Is Good Mileage For A Used Infiniti Q50?

A used Infinity Q50 is, as I will explain later in this guide, is a good purchase in almost all regards.

But there is always a certain mileage you should get a used car so that it does not give a lot of issues to you right out of the gate and also is capable of providing you a decent amount of mileage before it starts to break down.

Typically, a used Infinity Q50 is great to purchase if you are getting it below 50,000 miles, but considering the Infinity Q50’s great and reliable nature, you can even extend this to 100,000 miles as long as you are getting it in good condition.

How To Increase How Long Your Infiniti Q50 Last

If you make sure to follow the various tips scattered above, you should see a significant decrease in the number of problems in your Infinity Q50, but the car itself, despite having a few of them, is still prone to a few issues which can reduce its lifespan.

I will discuss these issues later, but for now, here are a few tips you can use to make sure that your Infinity Q50 will last much longer:

  • Lubricate the rotors and pads of the car.
  • Limited use of the turbocharger.
  • Limit off-roading and drifting.
  • Efficient and proper shifting of the gears.
  • Proper servicing and maintenance of pump seal.

By making sure to follow these specific tips, you will eliminate the biggest and most common problems which surround the Infinity Q50 and make sure that the issues which I will discuss below never happen.

This will overall also lead to a much better improvement in the lifespan of the vehicle.

Problems That Limit The Life Of Your Infiniti Q50

Such problems include:

  • Blown transmission.

Each car and model has its own gimmick or specialty, which a particular customer may enjoy and feel as if it is the main selling point of the vehicle.

Each car has a plethora of different features and utilities that many consider being must-buys which is why in this part of the article, I will highlight a few things which you should be looking for when buying an Infinity Q50.
