2017 INFINITI Q60

Typical onset: 40,000-80,000 mi

Symptoms: Excessive oil consumption (1+ quart per 1,000 miles), Rattling/knocking from lower engine on cold starts, White or blue smoke from exhaust under acceleration, Metal shavings in oil during changes, Check engine light with misfire codes or low oil pressure warnings

Fix: Complete engine rebuild or replacement required. Piston ring failure leads to bore scoring, necessitating short block replacement at minimum. Some cases require full long-block. 24-35 labor hours depending on approach. Infiniti extended warranty to 84k mi on some VINs but coverage inconsistent.

Estimated cost: $8,500-15,000

Typical onset: 50,000-90,000 mi

Symptoms: Harsh shifting or delayed engagement, Transmission slipping between gears, Coolant mixing with transmission fluid (strawberry milkshake appearance), Overheating transmission temperature warnings, Erratic gear hunting on highway

Fix: Internal cooler in radiator fails, cross-contaminating ATF and coolant. Requires radiator replacement, complete transmission flush (often multiple cycles), new ATF, and coolant system flush. If contamination is severe, transmission rebuild needed. 6-8 hours for cooler/flush, add 18-25 hours if trans damaged. Catch early or face total transmission failure.

Estimated cost: $1,800-3,200 (cooler/flush only), $5,500-8,000 (with trans rebuild)

Symptoms: Engine stalling while driving, especially under load, No-start condition with crank but no fire, Rough running and loss of power at highway speeds, Fuel pressure warning on instrument cluster, Sputtering or hesitation during acceleration

Fix: Low-pressure fuel pump in tank fails prematurely. Covered under NHTSA recall 21V-542 but many owners report dealers can't get parts or claim VIN not affected. Requires tank drop and pump replacement. 3-4 hours labor. If out of pocket (no recall coverage), parts are expensive from dealer.

Estimated cost: $0 (recall), $1,200-1,800 (if paying)

Typical onset: 45,000-75,000 mi

Symptoms: Clunking when shifting from Park to Drive/Reverse, Vibration through chassis at idle in gear, Excessive drivetrain movement felt during hard acceleration, Knocking sound over bumps from transmission tunnel area

Fix: Rear transmission mount (sometimes front as well) collapses due to soft rubber compound and torque from the twin-turbo. Simple replacement but requires trans support. 2-3 hours labor for rear mount, 4-5 hours if doing both mounts.

Estimated cost: $450-750 (rear only), $800-1,200 (both mounts)

Typical onset: 60,000-100,000 mi

Symptoms: Rough idle and misfires on cold starts, Loss of power and throttle response, Check engine light with multiple misfire codes (P0300-P0306), Hesitation or stumble during light acceleration, Increased fuel consumption

Fix: Direct injection with no port injection means intake valves never get fuel wash, leading to heavy carbon deposits. Requires walnut blasting or chemical cleaning of intake ports. Must remove intake manifold and injectors. 5-7 hours labor. Preventive cleaning every 50-60k miles recommended on VR30.

Estimated cost: $650-1,100

Symptoms: Dual screens freeze on startup, requiring hard reset, Backup camera displays black screen or 'no signal', Navigation system crashes or reboots randomly, Bluetooth connectivity drops repeatedly, Touchscreen unresponsive to inputs

Fix: InTouch dual-screen system plagued with software bugs and failing camera modules. Software updates help some cases; camera replacement requires rear hatch trim removal. Module reflash takes 1-2 hours, camera replacement 1.5 hours. Infiniti issued several TSBs but no permanent fix for chronic freezing.

Estimated cost: $200-400 (software), $600-900 (camera hardware)
