2012 Infiniti Fx35
Vehicle Specs & Maintenance Data
The 2012 Infiniti Fx35 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 Fx35.
For oil changes, the 2012 Infiniti Fx35 takes 5W-30 Full Synthetic motor oil with a capacity of 4.6 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 Fx35, 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 2012 Infiniti Fx35 have reported 5 common issues including "Timing Chain Stretch and Noise", "Brake Caliper Seizure and Uneven Wear" and "AC Compressor and Condenser Failure". Scroll down to the Diagnostics tab for detailed descriptions, solutions, and estimated repair costs.

Common problems reported by 2012 Infiniti Fx35 owners, with recommended fixes and estimated repair costs.
Timing Chain Stretch and Noise
The VQ35HR engine's timing chain can stretch over time, causing a rattling or whining noise from the front of the engine, particularly on cold starts. As stretch progresses, camshaft timing codes (P0014, P0024) may appear, and the engine may run rough or lose power. The timing chain tensioners lose effectiveness as the chain elongates beyond their compensation range.
Replace the timing chain, chain guides, and tensioners as a complete set. This is a labor-intensive job requiring significant engine front disassembly. Use OEM Nissan/Infiniti timing components for reliability. Address the issue promptly, as a severely stretched chain can jump timing and cause valve-to-piston contact.
Est. Cost: $1,500 - $3,000Brake Caliper Seizure and Uneven Wear
The front brake calipers are prone to slide pin seizure, causing uneven brake pad wear where the inner pad wears significantly faster than the outer pad. This results in reduced braking efficiency, a pulling sensation during braking, and premature rotor damage. Road salt and lack of maintenance accelerate caliper pin corrosion.
Remove, clean, and relubricate the caliper slide pins with silicone-based brake grease. If the pins are severely corroded or the caliper bore is damaged, replace the caliper assembly. Replace brake pads and resurface or replace rotors. Perform this maintenance at every brake service to prevent recurrence.
Est. Cost: $200 - $800AC Compressor and Condenser Failure
The AC compressor can fail internally, sending metallic debris throughout the AC system. The condenser, located at the front of the vehicle, is also vulnerable to damage from road debris causing refrigerant leaks. Some owners report the AC system cycling on and off rapidly, blowing warm on one side, or failing to cool at all.
Replace the AC compressor, condenser, receiver/drier, and expansion valve as a system. Thoroughly flush all AC lines to remove any debris from the failed compressor. Failing to flush the system will cause the new compressor to fail prematurely from circulating debris.
Est. Cost: $1,000 - $2,500Power Steering Pump Whine and Leak
The power steering pump can develop a whining noise during turns and at low speeds, indicating worn internal vanes or low fluid from a leak. The high-pressure power steering lines and the pump itself can develop leaks at the seals and fittings. Low power steering fluid increases steering effort and accelerates pump wear.
Check the power steering fluid level and inspect all hoses and connections for leaks. If the pump is whining with correct fluid level, the pump needs replacement. Replace any leaking high-pressure or return lines. Use only Infiniti-specified power steering fluid (PSF) to prevent seal damage.
Est. Cost: $300 - $800Sunroof Drain Clog and Water Leak
The sunroof drain tubes can become clogged with debris, causing water to back up and leak into the cabin through the headliner, A-pillar, or onto the floorboards. The water can damage electrical components under the carpet, cause musty odors and mold growth, and stain the headliner material.
Clear the sunroof drain tubes by blowing compressed air through the drain channels at each corner of the sunroof tray. Some owners use a thin flexible wire to dislodge blockages. Clean the sunroof tray of debris regularly. If water has entered the cabin, dry the carpet and padding thoroughly to prevent mold and electrical damage.
Est. Cost: $50 - $400
