How Long Do Infiniti QX50 Last? (12 Important Facts) - Engine Patrol (1)

Here is the short answer to how long the Infiniti QX50 lasts:

The Infiniti QX50 is a highly reliable and durable crossover that can last 250,000 to 300,000 miles when properly maintained and driven conservatively. Based on driving 15,000 miles per year, you can expect the Infiniti QX50 to last 17 to 20 years before requiring overly expensive repairs.

How Many Miles Can You Expect from a Infiniti QX50?

It should come as no great surprise that the QX50 is expected to go the distance.

Infiniti is the luxury division of Japanese automaker Nissan, who have earned a reputation for building durable and dependable vehicles.

On the Nissan and Infiniti owners forum, one long-term member posted: “I know several people that have taken them to 200k and beyond…they’re an extremely well-built car, just like the Nissans….(they are Nissan!)”

Repair Pal ranks the EX35 3rd out of 11 for luxury compact SUVs and you can expect the same high standard from the QX50, which is essentially the same car.

On used car websites such as Car Gurus and AutoTrader, you can find lots of high mileage EX and QX models, many of which with over 200,000 miles and still going strong.

Once you approach the 250k mark, there’s a greater chance of incurring uneconomical repairs such as engine or transmission failure and there’s also a greater chance of poor reliability despite constant repairs.

At which point it’s best to invest your money into a new vehicle.

Keep in mind, if you want to reach high miles in your QX50 you have to be very pro-active with maintenance, and it’s even advised to go above and beyond the factory recommended maintenance as this is considered the bare minimum.

This means keeping all your filters and fluids fresh and of high-quality, preferably synthetic. Oil change intervals are critical for longevity.

Your style of driving is also a key factor; smooth controlled use of the gas and brake pedals will ensure wear and tear of components is kept to a minimum.

The life expectancy of your Infiniti QX50 will be cut short if you avoid:

  • Using quality parts
  • Service appointments
  • Routine oil changes
  • Regular car washes
  • Tire rotations
  • Driving smoothly

Do Infiniti QX50 Rust Easily?

The INFINITI QX50 is not expected to rust easily and there are minimal customer complaints pertaining to rust issues for both the EX35 and QX50. Infiniti models benefit from high-quality rust protection as standard from the factory and good quality paintwork.

According to INFINITI’s website, they provide an 84-month limited warranty on corrosion.

If your INFINITI QX60 is 7 years and younger, your local INFINITI dealership will cover the rust protection, treatment, repaint, and replacement of affected parts under warranty.

It’s important to note that the salt used to de-ice the roads has an adverse effect on cars. Salt, moisture, and salty air can accelerate the spread of rust.

Rust can affect any vehicle, but with regular car washes (including the under chassis and wheel wells) and the occasional wax coat, you should be able to keep it to an absolute minimum.

What is High Mileage for a Infiniti QX50?

An Infiniti QX50 with over 120,000 miles is considered high mileage. This means there is a higher chance of problems arising as most parts will have some degree of wear and tear. However, you should not assess the car on mileage alone.

Buying a high mileage QX won’t necessarily lead to a sour outcome – it really depends on how well it’s been looked after.

A well-maintained model with over 120,000 miles could well be a better option than one with 80,000 miles that had many owners and led a tough life or was previously a hire car.

If you’re buying a used Infiniti QX50, consider the following:

  1. Check that the car was properly maintained and the owner can provide evidence of this.
  2. Take it for a test drive, ask the owner to leave the engine cold and listen out for strange noises.
  3. Check for rust including under the car. Rust is a problem that will spread.
  4. As a general rule, less previous owners is better. More owners usually equate to more wear-and-tear. If one family owned it and drove the full mileage and serviced the car, then you can almost guarantee they took good care of it throughout their ownership.
  5. Examine the interior. The condition of the interior tells the story of how well the car was maintained and cared for.

Is the Infiniti QX50 Reliable?

The Infiniti QX50 and its predecessor the EX35 have received solid reliability ratings from the major auto review sites and it is considered one of the most reliable vehicles in the luxury compact SUV segment.

The QX50 isn’t perfect though and you’ll find a few complaints about it online here and there, but this is common for any vehicle.

The most common grievance professional reviewers have pertains to the inconsistent power delivery due to CVT automatic transmission although one owner had this to say:

“The car ‘experts’ love to complain about the CVT transmission. Don’t listen to that nonsense. You won’t be able to tell. Infiniti has done a great job with it. Drive the car. See for yourself.”

The QX50 received the following reliability reviews:

  • Kelley Blue Book’s consumer rating index gave the Infiniti QX50 an above-average reliability rating of 4.4/5.0.
  • J.D. Power gave the Infiniti QX50 an average reliability rating of 77/100.
  • Repair Pal ranks the EX35 (essentially the QX50) in 3rd place out of 11 luxury compact SUVs with a reliability score of 4.0/5.0

As with longevity, the reliability of your Infiniti QX50 will also depend on regular maintenance and adopting good driving habits.

The Best and Worst Years for the Infiniti QX50

We’ve done some digging to find the best and worst model years for the Infiniti QX50.

Worst Model Year

The worst year for the QX50 is the 2019 model year, it has received the worst customer feedback score across all model years.

On the popular car website the 2019 model year stands out as one to avoid, its overall rating based on owner reviews is 2.8 / 5.0 stars which is notably lower than its other years.

Complaints from unhappy owners include:

“Bought this car three weeks ago and it’s already in the shop for gas smells filling up my garage. So strong in fact that I have to either park my brand new luxury SUV outside in the cold or leave my garage door open for hours while it ‘cools off’.”

“This car has been with us for 75 days, of which it’s been in the shop for 70 of those days. Infiniti has been terrible to deal with. They “know” it has a lot of problems, but refuse to buy it back.”

And the most common and worrying complaint seems to be the car randomly stopping and hitting the brakes for no apparent reason.

Best Model Year

The 2023 and 2024 Infiniti QX50 models are the best model years, benefiting from a 2019 redesign that introduced a more luxurious interior and an innovative turbocharged engine, enhancing the driving experience and efficiency.

Each trim is powered by a turbocharged 2-liter 4-cylinder engine (268 horsepower, 280 pound-feet of torque) paired to a continuously variable automatic transmission (CVT).

Are Infiniti QX50 Expensive to Maintain?

The Infiniti QX50 is one of the most affordable vehicles in its class in terms of maintenance with costs averaging at $588 per year.

How Long Do the Brakes Last?

Infiniti QX50 brake pads will typically last between 25,000 and 65,000 miles although some will last beyond 80,000 miles. Brake pad longevity depends on a multitude of factors including style of driving, traffic conditions and climate.

  • You can expect your brakes to wear out sooner if you frequently stop and accelerate in rush-hour traffic.
  • Full and complete stops from a high speed are the #1 cause of premature brake pad wear.
  • A sporty driving style will lead to faster deterioration of brakes. A slow and steady style will help them last longer.

How Long Do the Tires Last?

The Infiniti QX50’s stock tires usually last around 30,000 to 50,000 miles or 2 to 4 years. However, they can wear out much sooner. This depends on various factors, such as driving habits, climate, and road conditions.

  • Rotate tires every 5,000 miles to ensure even wear.
  • Check your tire pressure every few weeks to make sure they’re at the correct tire pressure.
  • Have a mechanic or tire shop check your wheel alignment every 6 months.

How Long Do Infiniti QX50 Engines Last?

The Infiniti QX50 features a turbocharged 16-valve 2.0 liter engine producing 268hp which should last at least 250,000 miles with proper maintenance.

If you want your engine to go the distance then routine oil changes are a must.

How Long Do Infiniti QX50 Batteries Last?

The Infiniti QX50 12V battery should last between 3 – 5 years. A vehicle’s battery life varies depending on many factors such as climate, driving habits, and battery type, among many others.

  1. Keep your battery tightly fastened: The vibrations of your car can loosen the connections, potentially resulting in short circuits and internal damage.
  2. Limit short rides: Quick car rides prevent the battery from fully charging.
  3. Storage: Keep your Infiniti QX50 stored indoors to protect it from extreme temperature changes.
  4. Control Corrosion: Clean the terminals (toothbrush dipped in baking soda and water mixture) and keep them free from build-up.

How Long Do the Spark Plugs Last?

For the Infiniti QX50, Infiniti recommends changing the stock iridium spark plugs every 100,000 miles although they may last much longer with some owners changing them at 130,000 miles.

Spark plugs are usually inspected every time you take your car in for routine maintenance.

Signs of a fouled spark plug include:

  • Reduced gas mileage
  • Lack of acceleration
  • Rough idling
  • Hard starts
  • Engine misfires

What About Insurance Costs?

The average cost of full comprehensive coverage for an Infiniti QX50 is $1,586 per year or around $132 per month.

Insurance costs can vary from person to person; be sure to shop around to find the best potential deal.

Tips to Prolong the Life of Your Infiniti QX50

  1. Adopt smooth driving habits.
  2. Keep up to date with factory-recommended maintenance.
  3. Use quality parts and fluids.
  4. Keep on top of repairs to prevent them from developing into larger problems.

  6. Check your Infiniti QX50’s engine oil, coolant, brake, and transmission fluid levels and top them up when required.
  7. Keep your Infiniti QX50 stored in a garage to help protect it from the elements.
