These years are not necessarily “bad” but represent a period where known issues were still being ironed out, making them less desirable than later, more refined models.
Common Problems Across Infiniti QX80 Model Years
Beyond specific problematic years, certain issues tend to appear across various Infiniti QX80 models. Being aware of these can help you during a pre-purchase inspection, regardless of the year.
Hydraulic Body Motion Control (HBMC) System
As mentioned, the HBMC system is a frequent culprit for expensive repairs. This advanced suspension system, designed to provide a smoother ride and better handling, can develop leaks or outright failures.
Symptoms include a noticeable change in ride quality, vehicle leaning, or warning lights on the dashboard. Repair costs can easily run into thousands of dollars.
Brake System Wear
The QX80 is a heavy vehicle, and its braking system takes a significant load. Many owners report premature wear of brake pads and rotors, sometimes requiring replacement every 15,000-20,000 miles.
While regular maintenance is key, the frequency of these complaints suggests that the stock braking components might be undersized for the vehicle’s weight and performance capabilities.
Electrical and Sensor Malfunctions
Modern luxury vehicles are packed with electronics and sensors, and the QX80 is no exception. Owners have reported issues with:
- Parking sensors failing.
- Backup cameras glitching.
- Power liftgate motors malfunctioning.
- Infotainment screen freezing or becoming unresponsive.
- Issues with keyless entry and push-button start systems.
These issues, while often minor individually, can accumulate and detract significantly from the luxury experience.
Fuel System and Emissions Components
Some QX80 models have shown a tendency for issues related to the fuel system or emissions components. This can include problems with fuel pumps, oxygen sensors, or catalytic converters.
These issues often trigger “check engine” lights and can lead to reduced performance or failed emissions tests.
Interior Wear and Tear
While the QX80 boasts a luxurious interior, some owners have reported issues with the durability of certain materials. This can include:
- Cracking or fading of dashboard materials.
- Premature wear on leather seating surfaces.
- Malfunctioning interior trim pieces or buttons.
These are often aesthetic but can be frustrating in a premium vehicle.
Why Do Some Years Have More Problems?
Understanding the reasons behind certain model years being less reliable can provide valuable context when considering which Infiniti QX80 years to avoid.
First Model Year of a New Generation
The first year of a completely new generation (like the 2011 QX56) often comes with “teething problems.” Manufacturers introduce new designs, technologies, and production methods, and unforeseen issues can emerge once thousands of vehicles are on the road in various conditions.
These early production runs often serve as real-world testing grounds, and subsequent years typically benefit from these initial discoveries and refinements.
Significant Facelifts and Mid-Cycle Updates
While facelifts (like those in 2015 and 2018) often bring welcome improvements in styling and features, they can also introduce new components or integrate existing ones in new ways. Sometimes, this can lead to new or different issues, especially with complex electronic systems.
Component Sourcing and Design Flaws
A particular component from a supplier might have a design flaw or a batch of faulty parts. If this component is critical (like the HBMC system), it can affect a broad range of vehicles produced during that period.
Manufacturers often issue recalls or technical service bulletins (TSBs) to address these, but not all problems result in a recall.
Lack of Long-Term Testing
While vehicles undergo extensive testing before release, real-world conditions over tens of thousands of miles can reveal durability issues that short-term testing might miss. This is particularly true for heavy-duty components like transmissions, suspensions, and braking systems in large SUVs.
What to Look for When Buying a Used Infiniti QX80
Even if you’re looking at a year generally considered reliable, a thorough inspection is paramount. Here’s what to prioritize:
Check the Suspension System
Pay close attention to the ride quality. Listen for any unusual noises (clunks, squeaks) over bumps. Inspect for fluid leaks around the wheels and under the chassis, especially if it has the HBMC system. Look for any warning lights related to suspension.
A full suspension inspection by a qualified mechanic is highly recommended.
Inspect the Brakes
Look for signs of uneven rotor wear or excessively thin brake pads. During a test drive, pay attention to any pulsation in the pedal, squealing, or pulling to one side when braking. Ask for service records to see how often brakes have been replaced.
Test All Electronics
Spend time checking every button, switch, and screen. Verify that the infotainment system, navigation, climate control, power windows, seats, and all driver-assist features (if equipped) are functioning correctly.
Small electrical gremlins can be annoying and surprisingly expensive to trace and fix.
Examine the Transmission
During the test drive, pay attention to how the transmission shifts. It should be smooth and consistent, without any harsh jerks, slipping, or delayed engagement.
If possible, test it in various driving conditions, including highway speeds and stop-and-go traffic.
Review Service Records
A complete service history can reveal a lot about how the vehicle was maintained. Look for regular oil changes, transmission fluid services, brake replacements, and any major repairs.
A well-documented history indicates a diligent owner and can be a strong indicator of future reliability.
Get a Pre-Purchase Inspection (PPI)
This is arguably the most critical step. Have an independent, trusted mechanic perform a comprehensive inspection of the vehicle. They can identify potential issues that you might miss, including frame damage, engine problems, or hidden electrical faults.
This small investment can save you thousands in unexpected repairs down the line.
More Reliable Infiniti QX80 Years
While our focus is on which Infiniti QX80 years to avoid, it’s also helpful to know which years generally fare better. Later models, particularly those from 2016 onwards, tend to benefit from refinements and improvements made based on earlier model year feedback.
The 2018 facelift also brought significant interior and exterior updates, making these models feel more modern and potentially having fewer of the initial production issues.
- 2016-2017 QX80: These years generally show improved reliability compared to their predecessors, with many of the early second-generation kinks worked out.
- 2018-Present QX80: The refreshed models often represent the most refined versions of a generation. While no vehicle is perfect, these years typically offer the best blend of updated technology and proven mechanicals.
Always remember that individual vehicle history and maintenance are critical factors, regardless of the model year’s general reputation.
Alternative Luxury SUVs to Consider
If the potential issues with certain Infiniti QX80 years give you pause, there are several other full-size luxury SUVs worth considering. These alternatives might offer different balances of reliability, features, and price points.
- Lexus LX: Known for its legendary reliability and strong resale value, though often at a higher price point.
