2022 Infiniti Qx50
Vehicle Specs & Maintenance Data
The 2022 Infiniti Qx50 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 Qx50.
For oil changes, the 2022 Infiniti Qx50 takes 0W-20 Full Synthetic motor oil with a capacity of 4.5 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 Qx50, 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.
Owners of the 2022 Infiniti Qx50 have reported 5 common issues including "VC-Turbo Engine Excessive Oil Consumption", "CVT Jerkiness and Hesitation" and "ProPilot Assist Camera Fogging and Failure". Scroll down to the Diagnostics tab for detailed descriptions, solutions, and estimated repair costs.
Specifications on this page are compiled from multiple publicly available sources including manufacturer documentation, NHTSA data, and automotive databases. Always cross-reference with your owner's manual or official factory documentation before purchasing parts or performing any service.

Common problems reported by 2022 Infiniti Qx50 owners, with recommended fixes and estimated repair costs.
VC-Turbo Engine Excessive Oil Consumption
The 2.0L variable compression turbo engine (KR20DDET) consumes oil at an abnormally high rate, with some owners reporting 1 quart every 1,500-2,000 miles. The variable compression mechanism adds complexity that contributes to oil seepage past piston rings. Low oil warnings appear frequently between oil changes.
Nissan/Infiniti considers up to 1 quart per 3,000 miles within specification. An oil consumption test must be performed to document excessive use. If consumption exceeds the threshold, piston ring replacement or short block replacement may be authorized under warranty.
Est. Cost: $0 (warranty) / $4,000 - $8,000 (out of warranty engine work)CVT Jerkiness and Hesitation
The CVT transmission paired with the VC-Turbo engine exhibits jerky acceleration from a stop, rubber-banding effect during moderate acceleration, and hesitation when passing. The combination of the variable compression engine and CVT creates an unusual and often unpleasant driving experience.
A TCM software update can improve shift simulation behavior. TSB ITB20-019 addresses CVT programming updates for improved driveability. A CVT fluid exchange with NS-3 fluid may also improve smoothness. The CVT re-learns driving patterns over 200-300 miles after a reset.
Est. Cost: $0 (warranty software update) / $200 - $400 (CVT fluid exchange)ProPilot Assist Camera Fogging and Failure
The forward-facing camera used for ProPilot Assist and automatic emergency braking fogs up internally or develops condensation, causing the driver assistance systems to deactivate with a warning. The camera is mounted behind the windshield in a sealed housing that traps moisture.
The camera housing or the camera module itself must be replaced to resolve internal fogging. Aftermarket moisture absorbing packets placed near the camera area are not a permanent fix. Ensure the windshield is properly sealed around the camera mount area.
Est. Cost: $300 - $800 (camera module replacement)Rear Hatch Strut Weakness
The rear hatch gas struts lose their holding force prematurely, causing the hatch to not fully open or to slowly close on its own. The issue is especially problematic in cold weather and for shorter owners who may be struck by the descending hatch.
Replace both rear hatch gas struts as a pair. OEM replacement struts have the same tendency to weaken, so some owners opt for aftermarket power liftgate strut kits. The struts are relatively easy to replace without special tools.
Est. Cost: $100 - $250 (pair of gas struts) / $500 - $1,000 (power liftgate conversion)Automatic Emergency Braking False Activation
The AEB system activates without any obstacle present, causing sudden unexpected braking. Reports mention it triggering near guardrails, parked cars on the side of the road, and overhead signs. NHTSA has received numerous complaints about false AEB activation on QX50 models.
Dealer recalibration of the front radar and camera sensors. Infiniti has issued software updates to reduce false activation sensitivity. If the radar sensor has been damaged by a minor front-end impact, it may need replacement and recalibration.
Est. Cost: $0 (software update) / $400 - $1,000 (sensor replacement and calibration)
