2014 INFINITI QX60

Typical onset: 70,000-130,000 mi

Symptoms: Coolant mixing with CVT fluid (strawberry milkshake appearance in radiator or transmission), Transmission slipping, shuddering, or delayed engagement after cooler breach, Check engine light with P0868 (transmission fluid pressure low) or P17F0 codes, Overheating transmission, burnt fluid smell

Fix: The built-in radiator cooler fails internally, cross-contaminating coolant and CVT fluid. Requires CVT replacement if contamination occurred (12-16 hours), plus radiator, fluid flush of entire cooling system, and often auxiliary cooler installation. If caught immediately before mixing, external cooler bypass and radiator replacement may save the CVT (6-8 hours).

Estimated cost: $5,500-8,500

Typical onset: 60,000-100,000 mi

Symptoms: Vibration or shudder during light acceleration 15-40 mph, Hesitation when accelerating from stop, Roughness disappears when transmission is cold, returns when warm, No check engine light in early stages

Fix: Valve body wear causes pressure control issues. Nissan issued TSB NTB13-068a addressing this with updated CVT fluid (NS-3) and valve body replacement if needed. Fluid change alone sometimes helps temporarily (2 hours), but valve body replacement is the real fix (8-10 hours). Some cases require full CVT replacement if internal wear is advanced.

Estimated cost: $400-3,800

Typical onset: 120,000-180,000 mi

Symptoms: Cold-start rattle for 2-5 seconds from engine front, Check engine light with P0011/P0021 (cam position timing over-advanced), Rough idle or poor performance, Metallic rattling under acceleration

Fix: The VQ35DE's secondary timing chains and guides wear, causing slack. Requires front timing cover removal, replacement of primary chain, secondary chains, tensioners, and guides (12-15 hours). Critical to address before chain jumps timing or breaks—catastrophic engine damage results. This job requires dropping the subframe for access on the transverse V6.

Estimated cost: $2,800-4,200

Typical onset: 80,000-120,000 mi

Symptoms: Clunking or thudding when accelerating or braking, Excessive engine movement visible when shifting from Park to Drive, Vibration transmitted through steering wheel or floorboard, Metal-on-metal contact noise over bumps

Fix: The hydraulic front mount (torque strut) separates internally, allowing excessive engine movement. Common across Nissan V6 FWD platforms. Replacement is straightforward but requires supporting engine weight (1.5-2 hours). Often replaced along with transmission mount which shows similar wear pattern.

Estimated cost: $350-600

Typical onset: 100,000-150,000 mi

Symptoms: Grinding or whining noise from center of vehicle during turns, AWD warning light illuminated, Fluid puddle under center of vehicle (differential area), Binding sensation in tight turns

Fix: The rear-mounted transfer case develops chain stretch or bearing wear, especially if fluid service was neglected (30k mile intervals recommended). Seal leaks are common at output shaft. Transfer case R&R and rebuild or replacement required (6-8 hours). Many shops opt for reman units due to parts availability.

Estimated cost: $2,200-3,500

Typical onset: 90,000-140,000 mi

Symptoms: Power steering fluid leak at inner tie rod boots, Groaning or moaning noise when turning at low speeds (parking lots), Intermittent heavy steering effort, especially when cold, Fluid drips visible on subframe or ground

Fix: Rack seals fail, leaking fluid into tie rod boots. The electronic power steering pump can also develop noise issues. Rack replacement requires subframe lowering and alignment (5-7 hours). Pump replacement alone is 3-4 hours if that's the noise source.

Estimated cost: $1,400-2,200
