If you’re eyeing the Infiniti QX80, you’re likely drawn to its V8 engine, roomy interior, and imposing road presence. But as a savvy car buyer, you’re probably wondering: how long does the Infiniti QX80s last?

We’re here to dive into the QX80’s longevity, reliability, and common quirks. Whether you’re considering a new model or hunting for a used gem, we’ll give you the lowdown on what to expect from the QX80’s lifespan. For today’s post, let’s talk about its durability, highlight key factors for used models, and weigh in on whether high-mileage QX80s are worth your investment.

Just How Reliable is the Infiniti QX80?

You might be surprised to learn that the Infiniti QX80 punches above its weight in reliability. RepairPal gives this luxury titan a 3.5 out of 5.0 reliability rating, crowning it the champion among 19 luxury full-size SUVs. That’s an impressive feat in a segment not typically known for bulletproof dependability.

The QX80’s reliability story gets even better when you look at the numbers. Owners spend an average of $718 annually on repairs - significantly less than the $1,127 typical for its luxurious peers. You might find yourself at the mechanic a bit more often (0.7 times a year versus 0.4 for average vehicles), but here’s the kicker: only 8% of these visits involve serious issues. Compare that to 19% for other luxury full-size SUVs, and you’ll see why the QX80 earns its reliability stripes.

In essence, while you might need to roll up to the shop a tad more frequently, your wallet won’t take as big a hit when you do. This resilience plays a significant role in answering the question: how long do Infiniti QX80s last?

How Long Do Infiniti QX80s Last?

When it comes to longevity, the QX80 can be quite the marathon runner. With proper care, many of these SUVs cruise well past the 100,000-mile mark, with some pushing beyond 200,000 miles.

Take this owner’s tale: their 2011 QX56 (the QX80’s predecessor) clocked an impressive 305,000 miles with minimal repairs beyond routine maintenance. Another driver reported putting 180,000 miles on their Nissan Armada (the QX80’s cousin) before passing it on - and it was still going strong.

While not exactly conclusive, these anecdotes suggest that a well-maintained QX80 could be your trusty road companion for a decade or more, potentially racking up 200,000+ miles. Just remember, your mileage may vary depending on how you drive, maintain, and where you live. So when asking, “How long do Infiniti QX80s last?” the answer often depends on how well you care for your vehicle.

How Many Miles are Too Many for a Used Infiniti QX80?

When you’re prowling the used car lots for a QX80, don’t let high mileage scare you off immediately. While some buyers get jittery about six-digit odometer readings, the QX80’s solid construction and reliability record suggests there’s often plenty of life left in these high-milers.

Many car experts agree that today’s well-maintained vehicles can often soldier on for 200,000 miles or more. For a QX80, a model with 100,000 to 150,000 miles could still have plenty of road trips in its future, provided it’s been treated right.

That said, as the miles pile up, so does the chance of needing bigger repairs. If you’re eyeing a QX80 with 150,000+ miles, you’ll want to put on your detective hat. Scrutinize its condition and maintenance history closely. Pay extra attention to big-ticket items like the transmission, suspension, and engine.

Should I Buy a Used Infiniti QX80 with More Than 100k?

Snagging a used QX80 with over 100,000 miles can be a smart move for the right buyer. You’re getting a lot of luxury and capability for a fraction of the new car price. But before you sign on the dotted line, consider these factors:

  1. Maintenance records: A detailed service history is gold. Regular oil changes, timely timing chain replacements, and other scheduled maintenance can add years to the QX80’s life.
  2. Overall condition: Give the vehicle a thorough once-over. A well-kept exterior and interior often indicate an owner who took good care of the mechanical bits, too.
  3. Price: High mileage should mean a lower price tag. Make sure you’re getting a fair deal based on the vehicle’s age and odometer reading.
  4. Your plans: If you’re aiming to rack up miles quickly, a lower-mileage option might serve you better. For occasional use, a higher-mileage QX80 could be a budget-friendly choice.
  5. Repair budget: Even with the QX80’s good reliability record, older, high-mileage vehicles typically need more frequent TLC. Make sure you’ve got some cash set aside for potential repairs.

If these boxes check out and the price is right, a used QX80 with 100,000+ miles could give you years of luxurious cruising without breaking the bank.

Common Infiniti QX80 Problems

While the QX80 boasts above-average reliability, it’s not immune to issues. Knowing these common quirks can help you spot potential problems and budget for future repairs:

  1. Transmission hiccups: Some drivers report rough shifting, hesitation, and slipping, especially in models with the seven-speed automatic.
  2. Engine quirks: Earlier models might guzzle oil faster than expected. Some owners have experienced stalling and rough idling, often tied to wonky ignition coils or fuel injectors.
  3. Electrical issues: The infotainment system can be a source of frustration, with reports of unresponsive touchscreens and connectivity issues. Some models also struggle with various sensors and electronic components.
  4. Suspension woes: Premature wear of parts like struts and bushings can lead to a bumpier ride and more road noise than you’d expect in a luxury vehicle.
  5. Batteries not holding charge: Some owners, particularly of the 2014 model, found their batteries struggling to hold a charge.

Keep in mind that these issues aren’t universal. They may pop up more in certain model years or under specific conditions. Staying on top of maintenance and addressing problems early can help keep many of these headaches at bay.

Final Thoughts

The Infiniti QX80 offers a unique blend of luxury, power, and surprisingly good reliability that makes it an intriguing option in the used market. With proper care, these SUVs can easily surpass 200,000 miles, providing years of comfortable cruising.

While high-mileage examples can be tempting budget-wise, you’ll need to weigh the potential savings against the likelihood of more frequent repairs. A thorough inspection and complete maintenance history are your best allies when considering a used QX80. In the end, how long Infiniti QX80s last largely depends on their past treatment and your future care?
