The 2012 Nissan Elgrand is a JDM luxury minivan sharing the VQ35DE V6 with other Nissans of the era, inheriting that engine's well-documented timing chain and oil consumption issues. Transmission cooler failures and CVT concerns (on CVT-equipped models) are the other major headaches.
Timing Chain Stretch and Guide Failure (VQ35DE V6)
Common · high severityTypical onset: 80,000-130,000 mi
Symptoms: Cold-start rattle for 2-5 seconds that worsens over time, Check engine light with P0011/P0021 cam correlation codes, Loss of power and poor fuel economy, Catastrophic engine failure if chain jumps timing
Fix: Complete timing chain kit replacement including guides, tensioners, and both chains. Requires front cover removal, 8-12 hours labor. Often discover worn cam phasers and oil pump wear during teardown. Some techs replace valve cover gaskets and front main seal while in there.
Estimated cost: $2,200-3,800
Transmission Oil Cooler Failure (Coolant-ATF Cross-Contamination)
Common · high severityTypical onset: 70,000-120,000 mi
Symptoms: Milky pink fluid in coolant reservoir or on dipstick, Transmission slipping or delayed engagement, Overheating transmission or engine, Complete transmission failure if not caught early
Fix: Replace external oil cooler, flush both cooling system and transmission completely (multiple drain/fills), replace radiator if internal cooler has failed. If ATF contaminated coolant system, heater core may clog. If coolant entered transmission, rebuild/replacement often required. 4-6 hours for cooler only, 15+ hours if transmission damaged.
Estimated cost: $800-1,200 (cooler only), $3,500-6,500 (with transmission damage)
Valve Lifter Tick and Collapse (VQ35DE)
Occasional · medium severityTypical onset: 90,000-150,000 mi
Symptoms: Persistent ticking noise at idle that doesn't go away when warm, Noise increases with RPM, Misfires on specific cylinders if lifter fully collapses, P0300-P0306 codes when lifter fails completely
Fix: Replace all 24 lifters as a set—never do singles. Requires valve cover removal and cam carrier work. 6-8 hours labor. Critical to use OEM lifters and fresh 5W-30 oil; aftermarket lifters often fail quickly on this engine.
Estimated cost: $1,400-2,200
CVT Transmission Judder and Failure (CVT Models)
Occasional · high severityTypical onset: 60,000-100,000 mi
Symptoms: Shuddering or lurching during acceleration from stop, Whining or grinding noise from transmission, Hesitation or slipping between 20-40 mph, Overheating warnings, Limp mode or complete loss of forward gears
Fix: CVT fluid and filter service can help early symptoms (3 hours), but most judder cases progress to valve body or full CVT replacement. Nissan extended warranty to 120k/10yr on some CVTs but verify VIN eligibility. Used CVT replacement 12-16 hours, remanufactured unit recommended over used.
Estimated cost: $600-900 (fluid service), $4,500-7,000 (CVT replacement)
Excessive Oil Consumption (VQ35DE)
Occasional · medium severityTypical onset: 100,000+ mi
Symptoms: Burning 1 quart per 1,000-1,500 miles, Blue smoke on cold start or deceleration, Fouled spark plugs on cylinders 2, 4, 6 (exhaust side), Low oil pressure warning in extreme cases
Fix: Caused by worn piston rings or valve stem seals. Valve seals can be replaced with cylinder heads on (8-10 hours), but high-mileage engines often need full rebuild with rings, bearings, and honing. Top-end refresh buys time; full rebuild is permanent fix.
Estimated cost: $1,800-2,800 (valve seals), $5,000-8,000 (full rebuild)
Transmission Mounts Deterioration
Common · low severityTypical onset: 80,000-130,000 mi
Symptoms: Clunking when shifting from Park to Drive/Reverse, Excessive vibration at idle in gear, Visible sagging or torn rubber on mount inspection
Fix: Replace upper and lower transmission mounts. Access is tight but straightforward with proper lift. 2-3 hours labor. Recommend replacing all engine/trans mounts as a set if multiple are deteriorated.
Estimated cost: $400-700
Head Gasket Failure (QR25DE 2.5L I4)
Rare · high severityTypical onset: 120,000-180,000 mi
Symptoms: External coolant leaks from head/block mating surface, White smoke from exhaust, Coolant loss with no visible leaks, Overheating and bubbling in coolant reservoir
Fix: Head gasket replacement requires head removal, resurfacing, and often new head bolts (TTY). Check for warpage; excessive warpage requires head replacement or resurfacing. 10-14 hours labor. Less common than VQ35 timing issues but still seen on high-mileage 2.5L models.
Estimated cost: $1,800-2,800
Buy the V6 if you can afford the eventual timing chain job and stay on top of oil changes; avoid high-mileage CVT models unless transmission has been recently replaced or extensively serviced.
