In this guide, we’ll break down the INFINITI QX80 service intervals, explain why they matter, and highlight what services to expect at each milestone.
Why the INFINITI QX80 Service Schedule Matters
Luxury SUVs like the INFINITI QX80 are engineered with advanced systems that work together to deliver power, safety, and comfort. Regular service is crucial because it:
- Preserves performance: Oil changes, tire rotations, and brake inspections keep your QX80 operating smoothly and efficiently.
- Protects your investment: Keeping up with service enhances resale value and shows potential buyers you’ve cared for the vehicle.
- Prevents breakdowns: Catching small issues early—like worn belts or fluid leaks—can save thousands in repair costs.
- Ensures safety: Regular inspections of brakes, tires, and suspension components ensure your family’s safety on the road.
INFINITI recommends specific service intervals, usually every 5,000 miles, to address different systems and keep your SUV at its best.
INFINITI QX80 Service Intervals
Let’s walk through the major milestones in your INFINITI QX80’s maintenance schedule. While mileage is the most common marker, time also plays a role—so even if you don’t drive a lot, annual maintenance is still important.
Every 5,000 Miles / 6 Months
This is your basic maintenance interval, designed to keep the engine and tires in good health. Services typically include:
- Engine oil and filter change: Keeps the 5.6L V8 engine clean and protected.
- Tire rotation and inspection: Promotes even wear and prolongs tire life.
- Brake inspection: Checks pads, rotors, and fluid for safety.
- Fluid level check and top-off: Includes coolant, transmission fluid, windshield washer fluid, and power steering fluid.
- General multi-point inspection: Technicians will review lights, wipers, belts, hoses, and underbody components.
Even if you’re driving fewer miles, this service should be done at least twice a year to ensure your QX80 is always road-ready.
Every 10,000 Miles / 12 Months
At this interval, your QX80 will need additional care to keep major systems in good working order:
- Cabin air filter replacement: Improves air quality inside the SUV by removing dust and allergens.
- Engine air filter inspection/replacement: Ensures proper airflow and efficiency for the V8 engine.
- Brake fluid check: Brake performance can diminish over time if fluid absorbs moisture.
For drivers in harsh climates—hot, cold, or dusty environments—filters and fluids may need attention more frequently.
Every 20,000 Miles / 24 Months
This is a more comprehensive service interval where your INFINITI QX80 will undergo more detailed inspections and replacements:
- Replace engine air filter: Keeps the engine breathing clean air, which supports power and fuel economy.
- Inspect suspension and steering components: Ensures smooth handling and reduces premature tire wear.
- Check exhaust system: Identifies leaks, corrosion, or damage.
- Battery inspection: Tests charging and cranking performance, important for avoiding unexpected breakdowns.
This visit ensures that the larger systems in your SUV are functioning as intended.
Every 30,000 Miles / 36 Months
At this milestone, expect a more in-depth round of maintenance to address both wear items and preventative care:
- Brake fluid replacement: Helps maintain braking performance by flushing old, moisture-contaminated fluid.
- Replace cabin air filter: Keeps the interior clean and fresh.
- Inspect transmission fluid: Critical for smooth shifting in the QX80’s automatic transmission.
- Cooling system inspection: Helps prevent overheating and extends engine life.
This service is all about longevity, ensuring your QX80 continues to perform like new after years of use.
Every 60,000 Miles / 72 Months
This is one of the most important service intervals for your INFINITI QX80. Many major systems require attention at this point:
- Transmission fluid replacement: Essential for smooth gear changes and preventing costly transmission damage.
- Differential fluid replacement: Keeps your QX80’s AWD system operating properly.
- Inspect and replace spark plugs: Fresh spark plugs help maintain power, efficiency, and smooth starts.
- Cooling system service: Drain and refill coolant to prevent corrosion and overheating.
This milestone is an investment in your SUV’s long-term health and performance.
Every 90,000 Miles / 108 Months
As your QX80 enters higher mileage, more components require replacement to keep the vehicle safe and reliable:
- Replace spark plugs (if not already completed)
- Inspect timing components
- Inspect drive belts and replace as needed
- Brake system service (including fluid and hardware checks)
This is also the time for a very thorough inspection, catching any developing issues before they become serious.
Every 100,000 Miles and Beyond
Once your QX80 surpasses 100,000 miles, routine maintenance becomes even more important. Services at this stage may include:
- Coolant replacement
- Transmission fluid service
- Suspension and steering component replacement
- Regular tire and brake services
Many INFINITI QX80s can exceed 200,000 miles with proper care, making adherence to the maintenance schedule critical.
Additional Considerations for QX80 Owners
Beyond the standard schedule, your driving habits and environment can influence when service is needed.
- Heavy towing or hauling: Increases strain on the transmission, brakes, and cooling system. More frequent service may be necessary.
- Extreme climates: Hot summers or freezing winters can affect fluids, tires, and battery life.
- City vs. highway driving: Stop-and-go traffic causes more wear on brakes and fluids compared to long highway commutes.
Consult your owner’s manual or service advisor to tailor maintenance to your needs.

While independent shops may offer basic services, choosing an authorized INFINITI service center ensures:
- Factory-trained technicians with in-depth knowledge of INFINITI vehicles.
- Genuine INFINITI parts designed to fit and perform exactly as intended.
- Advanced diagnostic equipment for accurate and efficient service.
- Warranty protection on both parts and labor.
