The 2024 Infiniti Qx80 maintenance specs on this page cover the key fluids, torque values, and wear items you need for routine service. Use these numbers as a quick reference when performing oil changes, tire rotations, brake jobs, and other scheduled maintenance on your Infiniti Qx80.
For oil changes, the 2024 Infiniti Qx80 takes 5W-30 Full Synthetic motor oil with a capacity of 6.4 quarts. Brake fluid type is DOT 3, the recommended coolant is Blue Long Life Coolant (OAT), and transmission fluid is Nissan Matic S. Always use the manufacturer-recommended fluids to maintain warranty coverage and engine longevity.
When mounting wheels on the Infiniti Qx80, torque the lug nuts to 80 ft-lbs using a calibrated torque wrench. Over- or under-torquing can lead to warped brake rotors or loose wheels. Re-torque after 50 to 100 miles on newly installed wheels.

Common problems reported by 2024 Infiniti Qx80 owners, with recommended fixes and estimated repair costs.
Dated Infotainment System Lag and Crashes
The dual-screen infotainment system, carried over from previous generations, is extremely slow and prone to freezing and crashing. The upper screen frequently goes black when switching between navigation and audio. Boot-up time after starting the vehicle can exceed 30 seconds.
Infiniti has released software updates to improve system responsiveness, but the underlying hardware limitations persist. A full system reset by disconnecting the battery for 15 minutes can temporarily improve performance. Some owners have opted for aftermarket head unit upgrades.
Est. Cost: $0 (software update) / $1,500 - $3,500 (aftermarket head unit)Hydraulic Body Motion Control (HBMC) Suspension Leaks
QX80 models equipped with the Hydraulic Body Motion Control system develop fluid leaks from the interconnected shock absorbers and hydraulic lines. Symptoms include a bouncy ride, uneven vehicle stance, and wet spots on the shock bodies. The HBMC system is complex and costly to service.
Identify the leaking component (shock absorber, hydraulic line, or accumulator) and replace it. The HBMC fluid must be bled and refilled correctly using the Infiniti procedure. Some owners convert to conventional shock absorbers for reduced maintenance cost.
Est. Cost: $500 - $1,500 per shock / $2,000 - $4,000 for full system repairFuel Gauge Inaccuracy
The fuel gauge reads inaccurately, often showing significantly more or less fuel than is actually in the tank. Some owners report the gauge dropping suddenly from half to near-empty, while others report it reading full for an unusually long time before dropping. The issue is related to the fuel level sending unit.
Replace the fuel level sending unit in the fuel tank. In some cases, the fuel pump assembly must be replaced as a unit since the sender is integrated. Infiniti service bulletin addresses fuel gauge calibration procedures.
Est. Cost: $400 - $900 (sending unit) / $600 - $1,200 (pump assembly)Transfer Case and 4WD System Clunk
A noticeable clunking or banging noise occurs when transitioning between 2WD, Auto, and 4HI modes, or when making tight turns on dry pavement in 4WD mode. The transfer case shift fork and synchronizer wear prematurely, causing the harsh engagement.
A transfer case fluid change with the correct Nissan/Infiniti-specified fluid can improve shift quality. If the shift fork or synchronizer is worn, internal repair or transfer case replacement is needed. Avoid engaging 4WD on dry pavement.
Est. Cost: $150 - $300 (fluid change) / $1,500 - $3,500 (transfer case repair)Exhaust Manifold Cracking (VK56VD V8)
The VK56VD 5.6L V8 engine's exhaust manifolds are prone to cracking, typically at the weld joints connecting the tubes to the flange. Symptoms include a ticking noise on cold starts that may diminish as the engine warms up, exhaust smell in the cabin, and eventually a check engine light.
Replace the cracked exhaust manifold(s) with updated parts. Both driver and passenger side manifolds should be inspected, as the issue often appears on both sides. Aftermarket stainless steel headers are available as a longer-lasting alternative.
Est. Cost: $800 - $1,500 per side (OEM manifold) / $1,500 - $2,500 (aftermarket headers)
