2006 NISSAN STAGEA

Typical onset: 80,000-140,000 mi

Symptoms: Harsh 2-3 or 3-4 shifts, flaring on upshift, Limp mode with P0841 or P0868 codes, Delayed engagement into Drive or Reverse, Whining noise from trans bell housing area

Fix: RE5R05A is notorious for C-clutch pack wear and valve body bore scoring. Proper fix is rebuild with updated clutches and valve body reconditioning—12-16 hours labor. Band-aid flush/fluid change buys 10-20k miles at best. External cooler upgrade helps longevity on replacement units.

Estimated cost: $3,200-5,500

Typical onset: 120,000-180,000 mi

Symptoms: Cold-start rattle for 2-5 seconds that worsens over time, P0011/P0021 cam correlation codes, Rough idle and reduced power at high RPM, Metallic rattling under load

Fix: VQ35 uses secondary timing chains that stretch with age. Requires front cover removal, both primary and secondary chains, guides, and tensioners. 10-14 hours labor. Not an interference engine but will run poorly and risk guide breakage if ignored.

Estimated cost: $1,800-2,800

Typical onset: 100,000-150,000 mi

Symptoms: Ticking/tapping from valve covers, worse when cold, Noise persists after oil change with correct viscosity, Occasional P0300-series misfire codes, Loss of low-end torque

Fix: VQ engines develop lifter tick from collapsed hydraulic lash adjusters or worn cam lobes. Full job is 24 lifters plus inspect/resurface cams—8-12 hours per bank. Many owners live with the noise if no performance loss, but worn cams require head removal and machining.

Estimated cost: $1,200-3,500

Typical onset: 90,000-130,000 mi

Symptoms: Transmission fluid dripping from radiator area or frame rails, Low fluid level on dipstick, slipping under load, Pink coolant or oily residue near radiator bottom tank, Burnt smell after highway driving

Fix: Steel cooler lines rust at bends and fittings, especially in salt states. Aftermarket stainless lines are $200-300 in parts, 2-3 hours labor. Critical to catch early—running low on ATF destroys the already-fragile RE5R05A fast.

Estimated cost: $400-700

Typical onset: 80,000-120,000 mi

Symptoms: Clunk on throttle tip-in or shift into Drive/Reverse, Excessive driveline vibration at idle in gear, Visible sag or torn rubber on front mount, Shifter shake during acceleration

Fix: Rubber mount fatigues from the V6 torque. OEM Nissan part recommended over aftermarket—1.5 hours labor, straightforward job. Poly mounts add NVH but last longer if driven hard.

Estimated cost: $250-450

Typical onset: 110,000-160,000 mi

Symptoms: Visible wobble or out-of-round on crank pulley at idle, Serpentine belt shredding or chronic squealing, Vibration at specific RPM ranges (1,800-2,200), P0335 crank position sensor code intermittently

Fix: Outer ring delaminates from hub due to heat cycles. Dorman replacements are hit-or-miss; OEM Nissan or Fluidampr recommended. 2-3 hours labor with belt and tensioner replacement while in there.

Estimated cost: $450-750
