Vehicle Specs & Maintenance Data
The 2019 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 2019 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 83 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 2019 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)3 NHTSA safety recalls for the 2019 Infiniti Qx50. Check your VIN at NHTSA.gov
ENGINE AND ENGINE COOLING:ENGINE:HARD PARTS INTERNAL/MECHANICAL
Nissan North America, Inc. (Nissan) is recalling certain 2021-2024 Rogue, 2019-2020 Altima, 2019-2022 Infiniti QX50, and 2022 Infiniti QX55 vehicles equipped with 3-cylinder 1.5L or 4-cylinder 2.0L variable compression turbo (VC-Turbo) engines. The engine bearings may have manufacturing defects that can lead to engine failure.
Engine failure increases the risk of a crash. A bearing failure may cause a breach in the engine block, allowing hot oil to be discharged, increasing the risk of an engine fire.
Dealers will reprogram the engine control module (ECM) software, free of charge. Owner letters were mailed February 2, 2026. Owners may contact Nissan's customer service at 800-647-7261 or Infiniti's customer service at 1-800-662-6200. Nissan's numbers for this recall are R25A8/A9 and R25B1/B2.
BACK OVER PREVENTION: SENSING SYSTEM: CAMERA
Nissan North America, Inc. (Nissan) is recalling certain 2018-2019 Nissan Altima, Armada, Frontier, Kicks, Leaf, Maxima, Murano, NV, NV200, Pathfinder, Rogue, Rogue Sport, Sentra, Titan, Titan Diesel, Versa Note and Versa Sedan vehicles, as well as Infiniti Q50, Q60, QX30 and QX80 vehicles. Additionally included are 2019 Nissan GT-R and Taxi and Infiniti QX50, QX60, Q70, Q70L vehicles. The back-up camera and display settings can be adjusted such that the rear view image is no longer visible and the system will retain that setting the next time the vehicle is placed in reverse. As such, these vehicles fail to comply with the requirements of Federal Motor Vehicle Safety Standard (FMVSS) number 111, "Rear Visibility."
The lack of an image in the back-up camera display increases the risk of a crash.
Nissan will notify owners in phases, having dealers update the back-up camera settings software, free of charge. The recall began November 11, 2019 and all affected VINs should be activated. Owners may contact Nissan customer service at 1-800-867-7669 or INFINITI customer service at 1-800-662-6200.
AIR BAGS:KNEE BOLSTER
Nissan North America, Inc. (Nissan) is recalling certain 2019 INFINITI QX50 vehicles. In the event of a crash in very cold temperatures, the trim cover may separate unexpectedly from the passenger-side knee air bag module instead of splitting at the trim cover tear seam as designed.
If the passenger-side knee air bag cover detaches during deployment, it can increase the risk of injury.
INFINITI will notify owners, and retailers will replace the passenger-side knee air bag module, free of charge. The recall began October 23, 2018. Owners may contact INFINITI customer service at 1-800-662-6200.
