Common Problems & Known Issues

The 2006 Maxima with the VQ35DE is a solid performer, but transmission failure is the elephant in the room—the CVT (if equipped) is a ticking time bomb, while conventional automatics fare better. Engine oil consumption issues plague high-mileage units, sometimes catastrophically.

CVT Transmission Failure (CVT-equipped models)

Common · high severity
Typical onset: 80,000-130,000 mi
Symptoms: Shuddering or jerking during acceleration, especially 15-40 mph, Whining or grinding noise from transmission, Delayed engagement when shifting from Park to Drive, Check engine light with P0868, P0845, or P17F0 codes, Sudden loss of power or limp mode
Fix: CVT replacement is the only real fix once internal damage occurs—rebuilt units last 50,000-80,000 mi at best. Fluid changes every 30k can delay but not prevent failure. Figure 8-12 hours labor for R&R.
Estimated cost: $3,500-5,500

Excessive Oil Consumption / Piston Ring Failure

Common · high severity
Typical onset: 100,000-150,000 mi
Symptoms: Burning 1+ quart every 500-1,000 miles, Blue smoke from exhaust on startup or acceleration, Fouled spark plugs (oil-soaked), Rough idle and misfires as it worsens, Low oil pressure warning if neglected
Fix: VQ35DE engines develop ring land deposits and stuck rings. Band-aid: keep oil topped off religiously. Real fix requires engine disassembly, new rings, hone/re-ring job (20-25 hours), or short block swap (18-22 hours). Many shops just recommend used engine swap at this mileage.
Estimated cost: $3,800-6,500

Transmission Oil Cooler Line Corrosion

Common · medium severity
Typical onset: 70,000-120,000 mi
Symptoms: Transmission fluid leaking near radiator area, Pink or red fluid pooling under front of vehicle, Transmission overheating or erratic shifts if fluid level drops, Visible rust or green corrosion on steel cooler lines
Fix: Steel cooler lines rust through where they route near subframe—salt-belt cars worse. Replace both lines, not just the leaker. 2-3 hours labor, flush system.
Estimated cost: $350-650

Engine/Transmission Mount Failure

Common · medium severity
Typical onset: 80,000-130,000 mi
Symptoms: Excessive vibration at idle, especially in Drive, Clunking when accelerating or decelerating, Shifter vibration or hard engagement into gear, Visible tearing or fluid leaking from hydraulic mounts
Fix: Front and rear mounts collapse or tear—VQ35 torque plus CVT weight accelerates wear. Replace all three (front, rear, transmission) as a set. 3-4 hours labor.
Estimated cost: $450-750

Crankshaft Position Sensor Failure

Occasional · high severity
Typical onset: 90,000-140,000 mi
Symptoms: Random no-start condition—cranks but won't fire, Stalling while driving, especially when hot, Check engine light with P0335 or P0340 codes, Intermittent loss of RPM signal causes limp mode
Fix: Sensor mounted at rear of block near bellhousing—heat kills them. 1.5-2 hours labor due to access (tight space, requires raising engine slightly in some cases).
Estimated cost: $250-450

Front Lower Control Arm Bushing Deterioration

Occasional · low severity
Typical onset: 90,000-130,000 mi
Symptoms: Clunking over bumps from front suspension, Wandering or vague steering feel, Uneven tire wear on inside edge, Visible cracking or separation of rubber bushings
Fix: Bushings separate or tear—some opt for full control arm replacement vs. pressing new bushings. 2-3 hours labor for both sides, includes alignment.
Estimated cost: $400-700
Owner tips
  • If shopping used, avoid CVT-equipped cars over 80k unless transmission has been replaced with documentation—seriously
  • Check oil level every fill-up after 100k miles; VQ35DE oil consumption creeps up silently until catastrophic failure
  • Service CVT fluid every 30,000 miles with Nissan NS-2 fluid—extends life but won't prevent inevitable failure
  • Inspect transmission cooler lines annually in rust-belt states; catch leaks before fluid loss damages transmission
Great engine character and decent chassis, but CVT reliability makes this a gamble—buy a conventional automatic example under 80k with oil consumption test, or walk away.
