2014 Infiniti Q50
Vehicle Specs & Maintenance Data
The 2014 Infiniti Q50 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 Q50.
For oil changes, the 2014 Infiniti Q50 takes 5W-30 Full Synthetic motor oil with a capacity of 5.1 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 Q50, 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 2014 Infiniti Q50 owners, with recommended fixes and estimated repair costs.
Electronic Steering Rack Failure (Direct Adaptive Steering)
Models equipped with the Direct Adaptive Steering (steer-by-wire) system experience vague, disconnected steering feel and, in rare cases, complete loss of steering assist. Warning lights for the steering system appear on the dash. The steer-by-wire system uses electronic actuators rather than a traditional mechanical connection.
A steering ECU software update can improve the steering feel and responsiveness. If the steering actuator or the backup clutch mechanism has failed, the electronic steering rack assembly requires replacement. Traditional steering column models do not have this issue.
Est. Cost: $0 (software update) / $2,000 - $4,000 (steering rack replacement)InTouch Dual-Screen Infotainment Freezing
The dual touchscreen InTouch infotainment system frequently freezes, responds slowly to inputs, and occasionally displays a black screen on one or both displays. The system struggles particularly when using navigation and Bluetooth audio simultaneously. The design has not been significantly updated since the Q50's 2014 launch.
Perform a system reset by holding the power buttons on both screens simultaneously. Infiniti software updates improve stability marginally. Some owners have replaced the internal storage with a faster unit. Persistent issues may require head unit replacement.
Est. Cost: $0 (software update/reset) / $1,000 - $2,500 (head unit replacement)VR30DDTT Engine Oil Galley Gasket Leak
The 3.0L twin-turbo V6 (VR30DDTT) engine develops oil leaks from the oil galley gaskets, which are located between the engine block and the timing cover. Oil seeps onto the engine and can drip onto the exhaust, creating a burning smell. The leak is slow but persistent.
Replace the oil galley gaskets. This is a labor-intensive repair as it requires removal of the timing cover. Using the updated gasket part number is essential to prevent recurrence. The timing chain should be inspected while the cover is off.
Est. Cost: $1,200 - $2,500 (labor-intensive gasket replacement)Premature Brake Wear and Rotor Warping
Front brake pads and rotors wear prematurely, often requiring replacement by 25,000-30,000 miles. The rotors are prone to warping, causing brake pedal pulsation and steering wheel shimmy during braking. The 400 Red Sport model with larger Akebono brakes is less affected.
Replace front brake pads and rotors with quality aftermarket components rated for higher heat tolerance. Proper bed-in procedure for new pads and rotors is essential. Upgrading to slotted or drilled rotors with ceramic pads can extend replacement intervals.
Est. Cost: $300 - $600 (pads and rotors per axle) / $800 - $1,200 (upgraded brake kit)Rear Differential Pinion Seal Leak
The rear differential pinion seal develops a leak, causing differential fluid to drip from the front of the differential housing where the driveshaft connects. If the fluid level drops too low, differential gear damage can occur. A humming or whining noise from the rear may develop as fluid is lost.
Replace the pinion seal, which requires removing the driveshaft. The differential fluid should be drained and refilled with the correct specification fluid during the repair. Inspect the pinion bearing for wear while the seal is being replaced.
Est. Cost: $300 - $700 (pinion seal replacement)
