The 2009 Nissan Cube uses the CVT-equipped MR18DE 1.8L four-cylinder powertrain shared with Sentra/Versa, and inherits their notorious CVT failures and timing chain wear issues. Quirky styling hides serious mechanical vulnerabilities that make high-mileage examples expensive to keep running.
CVT Transmission Failure (RE0F08A/B)
Common · high severityTypical onset: 80,000-130,000 mi
Symptoms: Shuddering or lurching during acceleration, especially 20-40 mph, Whining or grinding noises from transmission, Hesitation when accelerating from stop, Check engine light with P0868 (low line pressure) or P0721 (output speed sensor), Transmission overheating warnings
Fix: Nissan's early CVTs are fundamentally flawed with inadequate cooling and weak valve bodies. Replacement with remanufactured unit is typical solution, 8-10 hours labor. Fluid changes every 30k miles may延 delay but not prevent failure. No affordable rebuild option that lasts.
Estimated cost: $3,200-4,800
Timing Chain Stretch and Guide Wear
Common · high severityTypical onset: 90,000-140,000 mi
Symptoms: Rattling noise on cold start that subsides after 10-15 seconds, Check engine light with P0011/P0021 (cam timing over-advanced), Rough idle and sluggish acceleration, Noise that persists indicates severe wear - catastrophic failure risk
Fix: MR18DE chain tensioners fail, allowing chain to slap against guides. Requires timing chain kit with guides, tensioners, and both camshaft position sensors (oil contamination kills them). Front cover removal, 9-12 hours labor. Do NOT ignore the rattle - jumped timing destroys valves.
Estimated cost: $1,800-2,600
Valve Lifter Collapse / Rocker Arm Wear
Occasional · medium severityTypical onset: 100,000-160,000 mi
Symptoms: Ticking or tapping noise from valve cover area, hot or cold, Noise increases with RPM, Loss of power and rough running if multiple lifters fail, May set misfire codes P0300-P0304
Fix: Hydraulic lifters wear or collapse, requiring replacement of all 16 lifters plus rocker arms if worn. Must remove camshafts. Often done alongside timing chain work since labor overlaps. Figure 7-9 hours standalone, 2-3 hours added if doing timing chain simultaneously.
Estimated cost: $1,400-2,200
Transmission Oil Cooler Leaks
Common · medium severityTypical onset: 70,000-120,000 mi
Symptoms: CVT fluid leaking from cooler lines at radiator, Pink/red fluid puddles under front of vehicle, Transmission running hot, Milky transmission fluid if cooler fails internally (cross-contamination with coolant)
Fix: External cooler lines corrode and leak, or internal radiator cooler fails allowing fluid mixing. External line replacement is 2-3 hours. Internal cooler failure requires radiator replacement AND complete transmission fluid flush, 4-5 hours total. Check fluid condition religiously.
Estimated cost: $400-900
Engine Mount Failures (Especially Front and Transmission)
Occasional · low severityTypical onset: 80,000-130,000 mi
Symptoms: Excessive vibration at idle in Drive, Clunking when shifting or accelerating, Engine rocking visible from driver's seat, Transmission mount failure causes severe gear change harshness
Fix: Cube's tall body amplifies mount wear. Transmission mount (3-4 hours) fails most often due to CVT vibration characteristics. Front mount adds 2 hours. Replace in pairs for best results. Aftermarket mounts acceptable for this application.
Estimated cost: $350-700
Fuel Sending Unit Failure
Occasional · low severitySymptoms: Fuel gauge reads empty when tank is full, or vice versa, Erratic gauge movement, Gauge stuck at one position, No check engine light typically
Fix: Fuel level sensor in tank fails. Requires fuel pump module removal, 2.5-3 hours. Can replace just the sender if available separately, otherwise full pump assembly. Tank must be dropped or body lifted for access.
Estimated cost: $400-650
Pass unless under 80k miles with documented CVT services and priced under $4,000 - the CVT time bomb and timing chain issues make high-mileage examples financial traps.
