2011 NISSAN MURANO

Typical onset: 80,000-130,000 mi

Symptoms: Transmission overheating warning, Metal shavings in CVT fluid, Erratic shifting or shuddering, Coolant mixing with CVT fluid (milky appearance)

Fix: Replace CVT oil cooler, flush transmission lines, replace CVT fluid. Often requires radiator replacement if internal cooler failed. 3-5 labor hours depending on contamination severity. If contamination entered CVT, full transmission replacement may be necessary.

Estimated cost: $800-1,200 for cooler only, $3,500-5,500 if CVT replacement needed

Typical onset: 90,000-150,000 mi

Symptoms: Blue smoke from exhaust on startup, Low oil warnings between changes, Burning oil smell, Check engine light with misfire codes, Engine knock or rattle

Fix: VQ35DE piston rings can fail or carbon-pack, burning 1+ quart per 1,000 miles. Minor cases need more frequent oil changes; severe cases require complete engine rebuild with new pistons, rings, bearings, and often crankshaft machining. 25-35 labor hours for full rebuild.

Estimated cost: $4,500-7,500 for full rebuild, $3,000-5,000 for short block replacement

Typical onset: 70,000-110,000 mi

Symptoms: Clunking when accelerating or braking, Excessive engine movement visible from engine bay, Vibration at idle in gear, Harsh engagement into drive or reverse

Fix: Hydraulic transmission mount deteriorates, allowing excessive drivetrain movement. Replace mount and inspect other engine mounts. 2-3 labor hours.

Estimated cost: $350-550

Typical onset: 100,000-140,000 mi

Symptoms: Delayed engagement when shifting to drive, Shuddering during acceleration, Transmission slipping or hesitating, Whining noise from transmission, Limp mode activation

Fix: Internal CVT valve body wears out, causing pressure control issues. Requires transmission removal, valve body replacement, and fresh CVT fluid. Sometimes caught early with fluid changes every 30k, but often progresses to full CVT failure. 8-12 labor hours for valve body; if internal clutches damaged, full CVT needed.

Estimated cost: $1,800-2,800 for valve body, $3,500-5,000 for CVT replacement

Typical onset: 100,000+ mi

Symptoms: Heavy engine knock at idle or under load, Metal shavings in oil, Low oil pressure warning, Catastrophic engine seizure

Fix: Result of prolonged oil consumption issues or neglected maintenance. Requires complete engine disassembly, crankshaft machining or replacement, new bearings throughout. Often more economical to install used engine. 30-40 labor hours for in-frame rebuild.

Estimated cost: $5,000-8,000 for rebuild, $3,500-5,500 for used engine swap

Typical onset: 120,000+ mi

Symptoms: White smoke from exhaust, Coolant loss with no visible leaks, Overheating under load, Rough idle and misfire, Oil contamination in coolant or vice versa

Fix: Usually caused by overheating event or extreme age. Requires both heads removed, machined, new gaskets, timing components inspected. Often find warped heads requiring replacement. 18-24 labor hours.

Estimated cost: $3,500-5,500
