[](https://pixabay.com/photos/infiniti-q50s-red-sport-racing-2758996/)The compact luxury car segment is a somewhat unique niche that has enjoyed quite a lot of popularity in recent years. The segment is where elegance meets everyday usability, with models like the BMW 3 Series, Mercedes-Benz C-Class, and Audi A4 bearing the flag of the compact luxury car market. Despite their smaller stature, luxury compacts are engineered for spirited driving experiences, with powerful engines, agile handling, and sport-tuned suspensions. One of the noteworthy entries in this market is the Infiniti Q50.

The Infiniti Q50 is a small luxury car that combines elegance and fun driving dynamics. It may not have created a splash compared to its aforementioned popular rivals. Still, the Q50 is a perfectly capable compact luxury model with muscular V6 engines, a striking exterior design, and a host of standard features. What truly sets the Infiniti Q50 apart from its counterparts is its commitment to safety features without compromising on style.

If you’re buying this small luxury car, you’re probably asking: how long do Infiniti Q50s last? In that case, you came to the right place. Luxury cars (even small ones) can be a significant investment, so it’s only natural you want to know how long they will last. So today, we discuss the longevity of the Q50, how many miles it will last, and if it’s a good investment for used car buyers.

Just How Reliable is the Infiniti Q50?

How long do Infiniti Q50s last? First, let’s talk about its reliability. More than anything, reliability is a vital factor when it comes to luxury vehicles. A reliable car needs fewer fixes, meaning it’s well-made and high-quality. So, a car with good reliability usually lasts longer, ensuring you get the most out of your luxury car investment.

Having said that, the Infiniti Q50 is a reliable luxury midsize car, according to RepairPal, with a rating of 4.0 out of 5.0 - making it the 10th most reliable out of 31 luxury midsize cars. It also has a low ownership cost (at least with luxury vehicle standards) and an average annual repair cost of $648, which is lower than the average of $652 for all vehicle models. In addition, the Q50 received a favorable rating of 83 out of 100 for Quality & Reliability from J.D. Power.


OTHER CAR SHOPPING APPS ARE OUTDATED

You won’t realize how outdated other car searching apps are until you try the CoPilot car shopping app. CoPilot does the hard work for you by searching all of the listings in your area and intelligently creating a personalized list of the best buys in the area that match what you’re looking for.


People all over the web echo the sentiment that the Q50 is a highly reliable small luxury car. For instance, users from this Reddit thread have lauded the Q50 for its reliability and have reported no significant issues with their vehicles, especially when they are well-maintained. A user highlighted that they’ve driven their Q50 for 50,000 miles since 2019 without any turbo or powertrain issues, stating the importance of regular oil changes every 7,500 miles at the dealership. Some users recommended getting the car as a Certified Pre-Owned (CPO) for added peace of mind. 

Like all vehicles, not all Q50 years are created equal, as some model years are less reliable than others. For example, the debut 2014 Q50 model grappled with reliability woes like warped brakes and steering issues.

How Many Miles Can an Infiniti Q50 Last?

Fortunately, the Q50’s inherent reliability has supported its life expectancy rather well. With proper maintenance, the Infiniti Q50 can last up to 200,000 miles. If you typically drive around 15,000 miles yearly, you can expect the Q50 to remain reliable for approximately 15 to 20 years. However, it’s worth noting that the actual lifespan of the vehicle may vary depending on how well it’s maintained and how it’s used.

Again, owners online have some positive things to say about the Q50’s lifespan. At the Infiniti Q50 Forum, one user expressed his opinion that the Q50 engine should last for at least 10-15 years, regardless of the annual mileage, as long as regular maintenance is carried out. He also highlighted that Infiniti cars are often driven harder than other brands, such as Subaru, due to their higher power. Another person pointed out that the Q50’s V6 engines are built to last. He believes that other components of the car, such as the body or electronics, might fail before the engine does.

As expected, the key to achieving such a high mileage for a Q50 requires religious care and maintenance and ensuring you stay on top of repairs and replacements.

How Many Miles are Too Many for a Used Infiniti Q50?

The general consensus is that the Q50, especially with the 3.7L engine, is mechanically reliable – but that doesn’t mean that a high mileage unit isn’t a red flag. While mileage is an important metric to consider, there are other factors to keep in mind when buying a used Q50 luxury sedan.

  • Geographical Considerations: The region where the car was used can affect its condition. For instance, cars from areas where road salt is used might have more wear and tear due to rust.
  • Warranty Considerations: Any car you can’t purchase a warranty for has too many miles. The Q50’s reliability is relatively on-point, and that a higher mileage Q50 might still be a good buy if it’s relatively problem-free
  • Engine Preferences: The 3.7L engine is recommended for its reliability, while the newer 3.0T engines have had reported issues with leaking turbos and water pumps.
  • Maintenance History: It’s crucial to check the car’s maintenance history. Regular servicing, fluid changes, and checks for rust or body damage can indicate how well the car was maintained.

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. 


Is a Used Infiniti Q50 a Worthy Investment?

How long do Infiniti Q50s last? We hope this quick guide has answered your burning questions about the Q50’s lifespan. The Infiniti Q50, especially models with the 3.7L engine, is often praised for its mechanical reliability. Additionally, many users on dedicated forums have expressed confidence in its longevity, even when considering higher mileage units.

When considering the longevity and reliability of a Q50, it’s crucial to take into account not only its mileage but also its overall condition and maintenance history, as well as the specific model year.
