The 2009 Nissan Quest is powered by the generally reliable VQ35DE 3.5L V6, but this generation suffers from catastrophic transmission cooler failures that can destroy the CVT, plus a documented engine oil consumption defect that leads to expensive rebuilds.
Transmission Oil Cooler Failure Leading to CVT Destruction (Strawberry Milkshake of Death)
Common · high severityTypical onset: 60,000-120,000 mi
Symptoms: Pink or milky transmission fluid (coolant contamination), Transmission slipping, delayed engagement, or complete failure, Overheating transmission, Check engine light with transmission codes
Fix: The radiator has an integrated transmission oil cooler that fails internally, allowing coolant and ATF to mix. This destroys the CVT transmission. Requires radiator replacement plus external transmission cooler installation (2-3 hrs labor) if caught early. If CVT is contaminated, add CVT replacement or rebuild (8-12 hrs labor). Many techs install an external cooler bypass as preventive measure.
Estimated cost: $800-1,200 radiator only; $4,500-7,000 with CVT replacement
Excessive Oil Consumption / Piston Ring Failure (VQ35DE Defect)
Common · high severityTypical onset: 80,000-150,000 mi
Symptoms: Burning one quart of oil every 500-1,500 miles, Blue smoke from exhaust on startup or acceleration, Fouled spark plugs, Low oil warning lights, potential engine damage if not monitored
Fix: The VQ35DE in this generation has documented piston ring and cylinder bore issues causing oil consumption. Nissan issued TSB NTB09-073a but no recall. Fix requires engine rebuild with new pistons, rings, and possibly bore work (18-24 hrs labor), or short block replacement (16-20 hrs labor). Some owners manage by adding oil frequently, but risk is catastrophic failure.
Estimated cost: $4,000-6,500 rebuild; $5,500-8,000 short block replacement
Transmission Mount Failure
Common · medium severityTypical onset: 70,000-120,000 mi
Symptoms: Clunking noise when shifting from park to drive or reverse, Excessive vibration at idle in gear, Visible sagging or movement of transmission, Harsh shifting feel
Fix: The front transmission mount (also called torque mount) deteriorates from the CVT's weight and vibration. Rubber separates from metal housing. Replacement is straightforward but requires supporting the transmission (1.5-2.5 hrs labor). Often replaced along with other motor mounts.
Estimated cost: $250-450
Fuel Filter Clogging (In-Tank)
Occasional · medium severityTypical onset: 100,000+ mi
Symptoms: Hard starting after sitting, Loss of power under acceleration, Sputtering at highway speeds, Check engine light with lean fuel codes
Fix: The fuel filter is integrated into the fuel pump assembly inside the tank. Not a common maintenance item, but when it clogs (often from contaminated fuel or tank debris), requires dropping the tank and replacing entire fuel pump assembly (2.5-3.5 hrs labor). Some techs replace just the filter if accessible, but pump assembly is more reliable long-term.
Estimated cost: $400-700
Power Sliding Door Motor and Cable Failures
Occasional · low severityTypical onset: 80,000-140,000 mi
Symptoms: Door opens or closes partially then stops, Grinding or clicking noises during operation, Door won't respond to switch or key fob, Error messages on dash about door system
Fix: The power sliding door motors and drive cables wear out from repeated use and exposure to elements. Each door has its own motor and cable system. Requires door panel removal and motor/cable replacement (2-3 hrs labor per door). Cables can fray and jump off track. Motors burn out from strain.
Estimated cost: $500-900 per door
Brake Pedal Linkage Bushing Wear (Recall 13V-421)
Occasional · high severitySymptoms: Increased brake pedal travel, Spongy brake pedal feel, Pedal goes closer to floor than normal, No change in braking performance initially, but increases stopping distance
Fix: NHTSA recall 13V-421 addresses brake pedal linkage bushing that can wear and separate, increasing pedal travel. Covered under recall - dealers replace the brake pedal push rod bushing (0.5-1 hr labor). Check if recall was performed on any used Quest. Critical safety item.
Estimated cost: $0 if recall not yet completed; $150-250 if out of pocket
Hard pass unless you can verify the radiator/cooler has been bypassed and the engine doesn't burn oil - the catastrophic transmission cooler failure and widespread oil consumption issues make this generation Quest a financial gamble even at low purchase prices.
