How Long Do Infiniti QX80 last? (12 Important Facts)

Formerly known as the QX56, the Infiniti QX80 is a full-size luxury SUV with seating for up to 8 people.

It boasts a stylish, upscale design both inside and out and offers a smooth ride and strong engine.

In this article we’ll take a closer look at the QX80’s average lifespan.

Here is the short answer to how long the Infiniti QX80 lasts:

The Infiniti QX80 is a durable luxury SUV that can last 250,000 to 300,000 miles when routinely maintained and driven conservatively. If you drive 15,000 miles per year, you can expect the Infiniti QX80 to last 17 to 20 years before requiring uneconomical repairs or breaking down.

How Many Miles Can You Expect from a Infiniti QX80?

For those that don’t know, Infiniti is the luxury division of Japanese automakers Nissan – a brand that has proven itself time and time again and has become synonymous with reliability.

The QX80 shares the same engine as the Nissan Armada, a 5.6-liter V8 capable of producing up to 400 horsepower, and these engines are well known to go the distance.

You can even find Armada, QX56 / QX80 models on the used market that have clocked mileages in excess of 300,000 miles.

A general estimate though will see these vehicles lasting in the 250 – 300k region, although there’s no set lifespan, it really depends on the owner and to some extent luck.

Sure they could last longer if you keep repairing them but the truth of the matter is, once a vehicle gets old the cost of repairs can be uneconomical, and you’d be better off just buying a new one.

If you follow the routine service intervals, drive sensibly and keep your SUV clean you’ll have every chance of hitting high numbers.

Failure to do so will see your vehicle scrapped before its reached any notable milestone.

Do Infiniti QX80 Rust Easily?

The Infiniti QX80 has good overall rust protection as standard from the factory and whilst there are few rust complaints some owners have complained about paint issues. Good ownership habits can reduce rust issues significantly.

One owner on the Infiniti Scene posted:

“Paint chipping, (100% not from road stones ) the chipping started after a couple of months, I have one chip at hood, one chip at the right rear door, one under the 5.6 lettering on the right side, one chip on the roof in front of the glass sunroof window.”

We would advise that if you encounter this problem, contact your dealer and have them touch up the paint chips, or better still, invest in a paint protection film or ceramic coating.

Due to the size of the QX80, it will encounter more road chips simply because it’s a bigger target.

In terms of rusting, which no vehicle is immune from, some known trouble spots on the QX80 are:

  • The roof
  • Exhaust system

Generally speaking, German luxury vehicles seem to have the upper hand in all things rust-related however you can minimize rust issues by:

  1. Regular car washes – especially after encoutering coastal air which is very salty and road salt, both of which will accelerate rust.
  2. If you have access to a garage, keep your QX80 stored inside to protect it from harsh weather elements.
  3. Waxing a couple of times per year will not only add a nice shine but will also help protect the paintwork.

What is High Mileage for a Infiniti QX80?

A Infiniti QX80 with over 100,000 miles is considered high mileage. The downside of high mileage cars is that they will likely need some repairs or replacing of parts in the not too distant future, although they may still have plenty of life left.

Purchasing a high mileage Infiniti QX80 won’t necessarily lead to a sour outcome – it really depends on how well its been looked after.

A well-kept Infiniti QX80 with over 100,000 miles will be a better option than one with 70,000 miles that’s been driven like a race car and poorly maintained.

Mileage isn’t everything.

If you’re buying a used Infiniti QX80, consider the following:

  1. Maintenance history. Check that the car was properly serviced and the owner can provide proof of this.
  2. Check for rust and paint chips. Make sure to check the roof and the underside of the vehicle, a bit of rust or a paint chip isn’t the end of the world but it may offer you some leverage when agreeing a price.
  3. Number of previous owners. As a general rule, less 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.
  4. How long you are planning on keeping the car. If you’re planning on keeping the car for a long time, evaluate whether the short-term savings outweigh spending extra on something more reliable.
  5. Examine the interior. The condition of the interior tells the story of how well the car was maintained and cared for. Does the steering wheel, pedals, or shifter look suspiciously new? If so, there’s a good chance that the car was heavily used, and those parts were just replaced before sale.

How Long Do the Brakes Last?

Infiniti QX80 brake pads will typically last between 30,000 and 40,000 miles. This can vary and depends mostly on your style of driving and the traffic conditions you normally drive in.

  • You can expect your brakes to wear out sooner if you frequently stop and accelerate in rush-hour traffic and last longer if you spend more time cruising on the highway
  • Full and complete stops from a high speed are the #1 cause of premature brake pad wear.

How Long Do the Tires Last?

The Infiniti QX80’s stock tires usually last around 40,000 to 50,000 miles or 3 to 5 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 QX80 Engines Last?

  • Reduced gas mileage
  • Lack of acceleration
