The Infiniti QX80 ranks first among 19 luxury full-size SUVs with a 3.5 out of 5.0 reliability rating. Yet owners still face unexpected repair bills that catch them off guard.
Owner reports show transmission problems plague many QX80s. The seven-speed automatic models struggle with rough shifting, hesitation, and slipping. The 2014 QX80’s problems are among the worst, with timing chain failures and battery issues making it a year buyers should avoid. NHTSA reports show the 2019 model suffers from electrical system failures. Each model year from 2015 through 2021 comes with its own set of unique issues.
This luxury SUV can give owners an expensive headache. Problems range from excessive oil consumption to faulty suspension and air suspension systems. City driving fuel economy hits 8 mpg in some cases – nowhere near the official rating of 13 mpg city. The 2025 model will feature a new twin-turbo V-6 engine that promises better efficiency. Current owners must deal with these pricey repairs, so potential buyers should consider these issues carefully.
Timing Chain Failure
Timing chain problems are among the most expensive and troublesome issues Infiniti QX80 owners face, especially with older models. Your vehicle’s timing chain plays a vital role – it synchronizes the crankshaft and camshaft to make sure valves open and close exactly when needed for cylinder combustion.
Timing Chain Failure symptoms
Your QX80 will show subtle warning signs of timing chain problems that get worse over time:
- Unusual engine noises: You’ll hear a rattling sound from the front of the engine, especially during cold starts – this is usually the first sign. Many owners say they hear a whining noise that goes away once the engine warms up.
- Performance issues: The chain stretches and causes less power, rough idling, and engine backfires.
- Check engine light: Your car’s computer detects timing problems and turns on warning lights.
- RPM fluctuations: The engine speed becomes inconsistent, particularly at idle.
- Cold start problems: The symptoms become more noticeable after the car sits overnight.
A QX80 owner’s experience shows this pattern – their car had just passed 120,000 miles when they noticed a whining sound that disappeared after the engine warmed up.
Timing Chain Failure causes
Several factors lead to timing chain failures in the QX80:
The chain naturally wears down and stretches with regular use, typically after . Poor oil maintenance speeds up this wear since proper lubrication keeps the timing chain healthy. 80,000-120,000 miles
The QX80’s earlier version (QX56) had known timing chain problems from 2011-2013. The plastic chain guides wore out too soon. Infiniti recalled these earlier models, but that campaign has ended. Nissan doesn’t cover these parts under warranty anymore.
Mechanics often find the chain rubbing against the timing cover with an overextended tensioner. This contact creates the noise owners hear.
Timing Chain Failure repair cost
A timing chain replacement stands out as one of the most expensive QX80 repairs that can seriously impact your finances:
Expect to pay for repairs. Here’s the breakdown: between AED 10,556.83 and AED 14,184.71
- Labor runs from AED 7,766.15 to AED 11,394.03
- Parts cost around AED 2,790.67
The costs stay high across different model years:
- 2014 QX80: AED 10,670.66 to AED 14,419.71
- 2017 QX80: AED 10,134.56 to AED 13,483.37
- 2020 QX80: AED 10,780.82 to AED 14,526.20
The repair’s high cost comes from extensive labor requirements. Mechanics must remove many parts, including the oil pan, timing cover, and 32 bolts that hold the cover. The timing chain connects to multiple systems like the oil pump and variable camshaft sprockets, so repairs often involve several related components.
The job needs special tools to remove and reinstall the oil sprayer correctly. This ensures proper chain lubrication. Without this precise work, your new chain might develop similar problems quickly.
Exhaust Manifold Cracks
The exhaust manifold plays a crucial role in the QX80’s engine system that collects and directs exhaust gasses away from the engine. Cracks in this component can set off a chain reaction of issues that affect both performance and safety.
Exhaust Manifold Cracks symptoms
Your QX80 will show several warning signs when the exhaust manifold starts to fail:
- Ticking or rumbling sounds: Most owners notice a distinct ticking noise that ever spread through their vehicle, especially during cold starts or acceleration. The sound gets louder as engine RPMs climb.
- Louder exhaust note: The exhaust noise becomes much more noticeable as cracks get worse.
- Smell of exhaust near the engine: You’ll notice strong exhaust fumes around the engine compartment when the manifold leaks.
- Check engine light illumination: The engine control module usually spots the problem and lights up your dashboard.
- Reduced acceleration and power: The car feels sluggish because exhaust gasses mess with combustion efficiency.
- Poor fuel economy: Your fuel efficiency drops by a lot as the engine runs less efficiently.
It’s worth mentioning that these symptoms might vanish temporarily once the engine warms up. The metal expands with heat and can temporarily seal small cracks, which makes diagnosing the problem trickier.
Exhaust Manifold Cracks causes
The QX80’s V8 engine has earned a reputation for exhaust manifold leaks after extended use. These problems are systemic and affect the Nissan Armada and Titan too, since they share the same platform and engine.
Here’s what causes these issues:
Heat cycles: The exhaust manifold goes through extreme temperature changes that make it expand and contract repeatedly. The metal structure weakens over time and eventually cracks.
Design issues: Some years of the QX80 seem more likely to have this problem. Infiniti tried to fix part of the issue in 2017 by adding an EGT (Exhaust Gas Temperature) sensor inside the exhaust manifold.
Failed support components: The manifold can crack faster if the system’s brackets or “hangers” fail because it has to support weight it wasn’t built to handle.
Exhaust Manifold Cracks repair cost
A cracked exhaust manifold ranks among the most expensive QX80 repairs. Here’s what you might pay for a complete replacement:
The average cost ranges between . This breaks down to: AED 9,877.52 and AED 11,114.96
- Labor: AED 2,643.80 to AED 3,877.57
- Parts: Around AED 7,237.39
Model-specific costs look like this:
- 2022-2021 QX80: AED 12,804.06 to AED 14,037.83
- 2019-2017 QX80: AED 8,474.84 to AED 9,712.28
- 2016-2015 QX80: AED 10,270.42 to AED 11,507.86
- 2014 QX80: AED 10,156.59 to AED 11,390.36
Repairs get complicated because the QX80’s exhaust manifold comes as one unit with the front catalytic converters. You’ll usually need to replace both parts together.
The manifold assembly alone costs between according to OEM parts listings. This doesn’t include labor or extra components. AED 4,278.91 and AED 5,523.70
You might save money by catching the problem early. A muffler shop can weld the exhaust leak if the catalytic converters haven’t been damaged yet. This option costs nowhere near as much as a complete replacement.
High Fuel Consumption
Poor fuel efficiency tops the list of Infiniti QX80’s problems. Owners often feel let down by the huge difference between advertised numbers and real-life fuel consumption. This luxury SUV guzzles premium fuel, creating hefty expenses that buyers rarely anticipate.
High Fuel Consumption symptoms
QX80’s excessive fuel consumption becomes obvious when you need frequent refills. Here’s what owners notice:
- Official vs. Reality Gap: Infiniti claims . Yet owners report much lower numbers.16 MPG city, 19 MPG highway, and 17 MPG combined
- Fuel gage drops faster: The needle moves quicker than expected, even during highway drives when the car should be most efficient.
- Range isn’t what you’d expect: The QX80’s massive 23.59-gallon fuel tank should give you 400 miles, but reality tells a different story.
- Numbers don’t add up: Manual calculations (miles driven divided by gallons used) usually show worse results than what the trip computer claims.
Most vehicles get better mileage as their engines break in. The QX80 bucks this trend. Fuel economy often gets worse as these vehicles age, especially in 2014-2019 models.
High Fuel Consumption causes
The QX80’s thirsty nature stems from several factors:
Vehicle-specific issues:
- Engine design: The 5.6L V8 engine focuses on power (400+ horsepower) rather than saving fuel.
- Weight: The QX80 weighs over 5,800 pounds, needing lots of energy to move.
- Aerodynamics: Wind resistance hits hard at highway speeds due to its tall, boxy shape.
- Drivetrain: The four-wheel-drive system adds extra weight and friction.
Maintenance-related causes:
- Dirty air filters: The engine burns more fuel when airflow gets restricted.
- Clogged fuel injectors: Bad spray patterns mean incomplete fuel burning.
- Wrong tire pressure: Under-inflated tires can cut fuel economy by up to 3%
- Bad oxygen sensors: These mess up the air-fuel mixture calculations.
- Stuck brake calipers: These create constant drag on the wheels.
Driving habit influences:
- Quick starts: Sharp acceleration drinks up fuel.
- Speed matters: Fuel efficiency drops after 50 mph.
- Too much idling: Your car can burn half a gallon per hour just sitting there.
- Extra weight: Every bit of unnecessary cargo costs you at the pump.
High Fuel Consumption repair cost
The QX80’s poor fuel economy hits your wallet in several ways:
Direct fuel expenses:
- Premium fuel requirements make each mile costlier than other SUVs.
- Yearly fuel costs run AED 3,700 to AED 7,400 more than expected, depending on how you drive.
Maintenance costs to improve efficiency:
- Air filter changes cost AED 150-300
- Fuel injector cleaning runs AED 400-800
- New oxygen sensors set you back AED 675-807
- Full brake system fixes (stuck calipers) cost AED 1,500-3,000
Long-term ownership costs:
- Ten-year maintenance and repair costs average AED 46,170.98.
- Yearly maintenance starts at AED 2,122.38 and climbs to AED 6,719.65 by year ten.
You can maximize your QX80’s fuel economy by:
- Keeping steady speeds and driving smoothly
- Planning trips to keep the engine warm
- Taking off roof racks when you don’t need them
- Using the right motor oil
- Checking tire pressure monthly – proper inflation saves up to 3% on fuel
The upcoming 2025 QX80 switches to a 3.5L twin-turbo V6. This new engine pumps out 450hp while promising better fuel economy than its V8 predecessor.
Infiniti QX80 Transmission Problems
Transmission problems in the Infiniti QX80 stand out as some of the most frustrating and expensive repairs among luxury SUVs. Many owners report these problems in several model years, which should raise red flags for anyone looking to buy one.
Transmission Problems symptoms
QX80 owners quickly notice a distinctive flutter or hesitation between gear shifts, especially between 2-3 or 3-4 gears. This fluttering usually happens around 1900 RPMs. Drivers also face these issues:
- Complete loss of acceleration after driving for short periods
- A whining noise coming from the transmission
- Stuttering/skipping sensation, especially when going uphill
- Problems that go away temporarily after letting the vehicle rest
The symptoms get worse as the transmission heats up. The QX80 sometimes loses all power after 10-30 minutes of driving, and drivers need to let it cool down before it works again.
Transmission Problems causes
A faulty torque converter causes most of the QX80’s transmission issues. This part moves power from the engine to the transmission, and bad shifts happen when it fails.
The other common causes include:
Worn internal components in the valve body, software glitches in the transmission control module (TCM), and transmission fluid problems. Sometimes transmission lines burst, which leads to fluid leaks and total failure.
One owner learned the hard way that towing in hot weather speeds up these problems after pulling a boat in 105-degree heat. These issues can show up early – some QX80s have transmission problems before hitting 30,000 miles.
Transmission Problems repair cost
Transmission repairs hit the wallet hard. A new transmission costs between AED 19,659.57 and AED 28,916.53. The torque converter alone sets owners back about AED 11,015.82.
Some owners still face similar issues even after such expensive repairs. One owner got a whole new transmission under warranty but ran into the same problems afterward.
Budget-conscious owners might find some relief with transmission fluid changes and special additives like “Shudder Fix”. ECM/TCM reprogramming sometimes fixes the issue temporarily.
Dealerships push for factory-authorized repairs with official parts. These come with a manufacturer’s warranty – something worth thinking about given the high costs.
Air Suspension Failure
The Infiniti QX80’s air suspension system combines pneumatic and electronic components to deliver unmatched ride comfort and proper vehicle height. Despite its sophisticated design, this system has become a frequent point of failure across several model years.
Air Suspension Failure symptoms
Your QX80’s air suspension problems show up most clearly through uneven vehicle height. Here’s what you might notice:
- Sagging rear suspension: The rear end sits lower than normal on one or both sides
- Gradual height reduction: The vehicle sinks lower when parked overnight
- “Nosedive” appearance: The front sits lower than the rear
- Excessive bouncing: The ride feels like a boat on rough water
- Compressor noise: The compressor makes strange sounds similar to “two rocks tumbling in a can”
- Intermittent height correction: The system lifts the vehicle at startup but sags again during drives
Many QX80 owners report their suspension works fine right after starting the vehicle but sags again while driving or after parking.
Air Suspension Failure causes
Service records show several factors that lead to air suspension failures:
The air compressor often fails because its exhaust valve solenoid seizes up internally. This vital part pumps high-pressure air to the springs to maintain system pressure.
Worn height sensors cause system failures quite often, especially on the driver’s side rear. These sensors keep track of the vehicle’s ride height and tell the compressor when adjustments are needed.
Air line leaks create another common problem, usually at connection points or where rubber components have deteriorated. Small leaks force the compressor to run non-stop, which leads to early failure.
Air Suspension Failure repair cost
Air suspension repairs rank among the costliest problems QX80 owners face:
A new air compressor costs between AED 2,805.36 and AED 2,930.21. The price jumps to AED 16,890.93 for a complete air suspension replacement that includes lines and components.
Your repair options include:
- Replacing just the failed component (compressor or height sensor)
- Converting to traditional suspension (not possible with QX80s that have the Deluxe Technology Package)
- Comprehensive system overhaul
Diagnostic costs start at AED 477.35 because the job needs specialized equipment to review the system properly. After replacing components, the vehicle needs a specific “height setting” procedure to ensure everything works correctly.
Battery Drain Issues
QX80 owners face a surprising problem – their luxury SUVs won’t start after sitting idle for just a few days. This is a big deal as it means that these vehicles can’t hold their battery charge during normal periods of inactivity.
Battery Drain Issues symptoms
The QX80’s battery problems show up in these ways:
- Complete failure to start: The vehicle won’t crank at all after sitting idle for 3-4 days
- Rapid battery discharge: The battery drains in just 25 minutes when owners use factory features like the DVD system
- Electrical component failures: Dashboard lights, headlights, and power windows act up before the battery dies completely
- Check engine light illumination: The vehicle’s computer gets wrong energy levels and triggers this warning
- Clicking sounds: A rapid clicking noise means the starter isn’t getting enough current
The strange part is that these problems pop up in newer models with low mileage and charging systems that work fine.
Battery Drain Issues causes
The QX80’s battery drain problems come from several sources:
Smart charging system design flaws: The QX80 uses a “smart charging” system that adjusts alternator output based on what it thinks the car needs. The system gets confused with short trips or irregular use.
Current sensor malfunction: The voltage sensor’s silicon parts age and drift on the negative cable, which leads to constant undercharging.
IPDM issues: The Intelligent Power Distribution Module should control charging but its logic can fail, preventing proper battery maintenance.
Parasitic drains: Electronics like the DVD player keep drawing power even when they seem off.
The problems are systemic enough that lawyers started a for 2019-2021 QX80 models class action investigation
Battery Drain Issues repair cost
Here’s what you’ll pay for battery fixes:
A new battery costs about AED 602, plus AED 514 for labor, adding up to AED 1,116. The real costs run higher since owners often need multiple batteries before finding the root problem.
Model-specific costs:
- 2023 QX80: AED 2,772 to AED 3,336
- 2017-2021 QX80: Around AED 1,743
- 2014-2016 QX80: About AED 1,743, like newer models
Nissan’s technicians found a that works well. They disconnect the “smart wire” between the IPDM and alternator. This change makes the alternator produce a steady 14.2V no matter how you drive permanent fix
Inaccurate Fuel Gage
QX80 owners face an unsettling quirk that ruins their peace of mind during road trips. The fuel gage drops dramatically after minimal driving. This strange behavior shows up most often in 2015-2016 models, making it one of the oddest infiniti qx80 problems owners should know about.
Inaccurate Fuel Gage symptoms
The fuel level readings drop way too fast right after filling up the tank. Here’s what happens:
- Accelerated initial drop: The gage falls to about 7/8 tank after just 10-15 minutes of driving
- Inconsistent behavior: The gage starts behaving normally at half tank and drops at a reasonable rate
- Misleading refill amounts: The tank only takes about 10 gallons at half-tank instead of what you’d expect
The gage drops so fast that many owners think they have a fuel leak. A 2016 QX80 owner reported, “After about 40 miles it reads 3/4 of a tank and around 125 miles it’s down to 1/2”. The range estimate stays pretty accurate despite the gage’s weird behavior.
Inaccurate Fuel Gage causes
The fuel level sending unit usually causes these inaccurate readings. This part uses a float mechanism with a variable resistor that sends signals to the dashboard gage.
Infiniti released a Technical Service Bulletin (TSB) for 2015-2016 models that pointed to a calibration problem in the gage cluster. The combination meter had a programming error that misread signals from working sensors [107, 108].
Inaccurate Fuel Gage repair cost
The fix needs a complete replacement of the combination meter assembly. The repair process includes:
- Removing the instrument cluster
- Installing an updated part with corrected calibration
- Ensuring the odometer reading transfers correctly
Parts and labor costs run between AED 8,034 and AED 8,408 for 2015-2016 models. The fuel level sensor costs about AED 952. Just replacing this sensor won’t fix the programming issue in affected vehicles.
Infiniti covered these repairs under warranty. Owners with expired warranties might save money with aftermarket instrument cluster repair services that charge around AED 660.
Camera and Sensor Malfunctions
Modern technology in the Infiniti QX80’s camera and sensor systems can be both a blessing and a curse. These advanced systems come with Around View Monitor cameras, sonar sensors, and parking assistance technologies. Owners often struggle when these complex systems start to fail.
Camera and Sensor Malfunctions symptoms
QX80 owners typically see these warning signs when cameras and sensors fail:
- Red X display: The screen shows a red X instead of camera footage from one or more cameras
- Continuous warning sounds: Empty spaces trigger false alerts from front sonar sensors
- Blank screens: Camera views become inaccessible when the infotainment display goes black
- System errors: The dashboard shows “Front sonar/sensor malfunction” messages without clear reasons
- Intermittent operation: The system works fine sometimes but fails randomly
These problems often show up at speeds under 10 mph, which makes parking especially difficult when drivers need these features most.
Camera and Sensor Malfunctions causes
Several factors can lead to these technological failures:
Rocks and road debris damage the protective plastic covers of sensors and cameras. The internal components can fail even when the damage isn’t visible.
Weather and environment take their toll too. The driver’s side mirror camera often fails because water collects inside mirror housings. Sensors give wrong readings from frost, snow, and dirt buildup.
The 2025 QX80 models face a specific issue. A software bug in the AVM system makes rearview cameras freeze and screens go blank. Nissan recalled to fix this problem about 37,000 vehicles.
Camera and Sensor Malfunctions repair cost
These high-tech systems don’t come cheap to fix:
A new park assist camera costs between AED 6429.57 and AED 6719.65. Labor runs from AED 627.90 to AED 921.66, while parts cost about AED 5801.67.
Model-specific repair costs:
- 2019 QX80: AED 6881.22 to AED 7174.97
- 2018 QX80: AED 6881.22 to AED 7174.97
- 2015-2016 QX80: AED 6249.64 to AED 6543.40
Backup warning sensors cost even more to replace—between AED 7369.58 and AED 7494.43.
Infotainment Screen Blackout
QX80 owners face frustrating screen blackouts that turn their luxury SUV’s high-tech infotainment system into a blank canvas. This problem affects multiple model years but shows up most often in 2020-2022 vehicles.
Infotainment Screen Blackout symptoms
The main sign that indicates trouble is when one or both screens suddenly go completely dark. QX80 owners also experience these issues:
- Color distortion: Screens might show incorrect brightness, saturation, and overexposed colors after software updates
- Clock freezing: The dash clock stays stuck at the time the car was last turned off
- Multiple system failures: Dark screens lead to other connected features stopping at once, including CarPlay, navigation, cameras, and climate controls
- Intermittent problems: The issue comes and goes randomly, sometimes fixing itself after restarts
A 2022 QX80 owner shared this experience: “Screens were off for a day or two then miraculously came back suddenly”.
Infotainment Screen Blackout causes
The investigation reveals several reasons why this happens:
Bad wiring harnesses behind the head unit create connection problems and need complete replacement. Software bugs from recent updates can “brick” the system, according to many complaints from 2021 model owners.
The Display Control Unit (DCU) sometimes fails and prevents text from showing up properly even when the backlight works. The system can also unexpectedly enter deep sleep mode due to electrical problems.
Infotainment Screen Blackout repair cost
Parts for a new Display Control Unit get pricey at AED 1,285.18. Both screen assemblies could cost up to AED 2,318.65 for parts alone.
Owners can try these temporary fixes before expensive repairs:
- Hold the volume knob/power button for 10-15 seconds to force a system reset
- Disconnect the negative battery terminal for 15-20 minutes
- Wait for official software updates from Infiniti
Infiniti released multiple software updates in 2021 to fix screen blackout problems, which shows they’re working to solve these systemic issues.
