The 2011 Nissan Cube with the 1.8L MR18DE is a quirky box on wheels with typical Nissan CVT reliability concerns and a notable timing chain wear issue that can lead to catastrophic engine damage if ignored. The 1.5L variant is less common in the US market.
CVT Transmission Failure / Judder
Common · high severity
Typical onset: 80,000-130,000 mi
Symptoms: Shuddering or jerking during acceleration, especially from a stop, Whining or grinding noise from transmission, Hesitation or delayed response when accelerating, Check engine light with CVT-related codes (P0731, P0732, P17F0)
Fix: Nissan's Jatco CVT7 is notorious for premature failure. Fluid changes every 30k can help but won't prevent underlying design flaws. Replacement or rebuild required, typically 8-12 labor hours for R&R plus rebuild time. Many shops recommend remanufactured units with updated components.
Estimated cost: $3,500-5,500
Timing Chain Stretch / Guide Failure
Common · high severity
Typical onset: 100,000-150,000 mi
Symptoms: Rattling noise from engine on cold start that quiets after warmup, Check engine light with timing correlation codes (P0011, P0021), Rough idle or misfires, Metal shavings in oil
Fix: The MR18DE is known for timing chain stretch and guide wear, especially if oil changes were neglected. Requires complete timing chain kit including guides, tensioners, and often the oil pump chain. 10-14 labor hours. If chain jumps timing, valve damage is likely, adding head work or full engine replacement.
Estimated cost: $1,800-3,200
Engine Oil Consumption / Lifter Noise
Common · medium severity
Typical onset: 70,000-120,000 mi
Symptoms: Ticking or tapping noise from valve train, Low oil light between changes, Burning 1+ quart per 1,000 miles, Blue smoke from exhaust on startup
Fix: MR18DE engines can develop excessive oil consumption due to piston ring wear or valve seal issues. Lifter noise often accompanies this due to oil starvation. Minor cases respond to high-mileage oil and frequent top-offs. Severe cases need engine rebuild with new rings, lifters, and seals. Full rebuild: 18-25 hours.
Estimated cost: $3,500-6,000
Transmission Oil Cooler Line Corrosion
Occasional · medium severity
Typical onset: 80,000-140,000 mi
Symptoms: CVT fluid leaking from front of engine bay, Low CVT fluid warning, Transmission overheating, Red fluid pooling under vehicle
Fix: Steel cooler lines rust through where they connect to radiator or run along subframe, especially in salt-belt states. Replacement requires draining CVT, replacing lines, and refilling with NS-2 or NS-3 fluid. 3-5 labor hours. Critical to address immediately to prevent CVT damage from low fluid.
Estimated cost: $600-1,200
Transmission Mount Failure
Occasional · low severity
Typical onset: 60,000-100,000 mi
Symptoms: Clunking when shifting from Park to Drive, Excessive engine movement visible when accelerating, Vibration at idle, Transmission noise louder in cabin
Fix: The front transmission mount deteriorates from CVT heat and age. Easy diagnosis by having someone rock the shifter while you watch engine movement. Replacement is straightforward, 1.5-2.5 hours with proper support equipment.
Estimated cost: $250-450
Fuel Pump / Fuel Filter Clogging
Occasional · medium severity
Typical onset: 90,000-140,000 mi
Symptoms: Hard starting, especially when hot, Sputtering or stumbling under acceleration, Stalling at idle after driving, Fuel pump whining audible from rear seat
Fix: The in-tank fuel pump strainer clogs or pump weakens over time. Filter is non-serviceable; requires fuel pump assembly replacement. 2-3 hours for pump R&R, requires dropping tank or using access panel if equipped.
Estimated cost: $500-900
Owner tips
Change CVT fluid every 30,000 miles with Nissan NS-2 or NS-3 spec fluid only—aftermarket fluids cause problems
Use quality 0W-20 or 5W-30 synthetic oil and change every 5,000 miles to prevent timing chain stretch
Inspect timing chain for rattle at every oil change after 80k miles; early replacement at first sign saves engine
Keep fuel tank above 1/4 to extend fuel pump life and prevent sediment issues
A fun, practical city car if you find one with documented CVT fluid changes and no timing chain rattle—otherwise, budget $4-6k for major repairs within 20k miles of purchase.
