2023 INFINITI Q60

Typical onset: 60,000-90,000 mi

Symptoms: Excessive oil consumption (1+ quart per 1,000 miles), Blue smoke on startup or under load, Fouled spark plugs, Check engine light for misfire codes

Fix: Requires engine teardown to replace piston rings, often all pistons. Some cases need cylinder honing if wear is significant. Expect 25-35 hours labor for a proper job with new rings, gaskets, and timing components while it's apart.

Estimated cost: $6,500-9,500

Typical onset: 70,000-110,000 mi

Symptoms: Metallic knocking from lower engine, Oil pressure warning light, Sudden loss of power, Metal shavings in oil filter during changes

Fix: Catastrophic failure requiring short block replacement or complete engine rebuild. Crankshaft typically needs machining or replacement. 30-40 hours labor minimum, often more economical to source a low-mileage used engine.

Estimated cost: $8,000-14,000

Typical onset: 50,000-80,000 mi

Symptoms: Transmission fluid in coolant or vice versa (strawberry milkshake in reservoir), Transmission slipping or harsh shifts, Overheating transmission temp warnings, Coolant loss with no external leaks

Fix: Oil cooler integrated into radiator fails internally, cross-contaminating fluids. Requires radiator replacement, complete transmission fluid flush (multiple cycles), often transmission filter and pan. Contamination can damage transmission if not caught early. 6-8 hours labor.

Estimated cost: $1,800-3,200

Typical onset: 40,000-70,000 mi

Symptoms: Clunking when shifting from park to drive, Vibration at idle that changes when in gear vs neutral, Excessive driveline movement on acceleration, Visible cracking or separation of rubber mount

Fix: Passenger-side transmission mount wears prematurely, especially on the 400hp Red Sport models. Replacement is straightforward but requires supporting the transmission. 2-3 hours labor.

Estimated cost: $400-650

Typical onset: 55,000-95,000 mi

Symptoms: Hard starting especially when hot, Intermittent loss of power, Engine running rough under load, Fuel pressure fault codes (P0087, P0191), Metallic debris in fuel filter

Fix: Direct-injection high-pressure pump fails, sometimes sending metal debris through system requiring fuel rail and injector cleaning/replacement. Pump replacement alone is 4-5 hours, but contamination cases require full fuel system service adding 6-8 hours.

Estimated cost: $1,500-4,500

Typical onset: 80,000-120,000 mi

Symptoms: Rattling on cold start for first 2-3 seconds, Check engine light for cam/crank correlation, Rough idle, Timing codes (P0011, P0021)

Fix: VR30 tensioners and guides wear over time, especially if oil changes were extended. Requires front engine disassembly, replacing chains, tensioners, guides, and VVT components. 12-16 hours labor.

Estimated cost: $3,200-5,000
