The 2017 Altima sits in the middle of Nissan's notorious CVT reliability crisis, with the Jatco CVT being the dominant failure point. The 2.5L engine also developed a catastrophic internal failure issue related to oil consumption and bearing wear that can grenade motors unexpectedly.
CVT Transmission Failure (Judder, Slipping, Complete Failure)
Common · high severityTypical onset: 60,000-120,000 mi
Symptoms: Shuddering or jerking during acceleration, especially 15-40 mph, Whining or grinding noise from transmission, Hesitation when accelerating from stop, Check engine light with P0868 (transmission fluid pressure) or P17F0 (CVT stepmotor), Sudden loss of power or failure to move
Fix: CVT replacement or rebuild required in most cases. Nissan extended warranty to 84k miles on some units, but many fail just outside that window. Fluid changes every 30k can delay but not prevent failure. Replacement is 8-12 hours labor.
Estimated cost: $3,500-5,500
Catastrophic 2.5L Engine Failure (Bearing/Piston Failure)
Occasional · high severityTypical onset: 80,000-140,000 mi
Symptoms: Excessive oil consumption (1 quart per 1,000 miles or worse), Loud knocking or ticking from engine block, Metal shavings in oil during changes, Sudden loss of power with severe knocking, Catastrophic failure with rod through block in worst cases
Fix: Engine rebuild or replacement necessary — short block minimum, often complete longblock. Issue stems from inadequate oil flow to rod bearings and piston ring wear causing oil consumption. 18-25 hours labor for proper rebuild or swap.
Estimated cost: $4,500-7,500
Transmission Oil Cooler Failure / Coolant-CVT Fluid Cross-Contamination
Occasional · high severityTypical onset: 70,000-110,000 mi
Symptoms: Milky or strawberry-colored CVT fluid, Transmission overheating warnings, Sudden CVT failure after coolant leak, Coolant loss with no visible external leak, White residue in coolant reservoir
Fix: The internal transmission cooler in the radiator fails, allowing coolant and CVT fluid to mix. Requires radiator replacement AND complete CVT fluid system flush or CVT replacement if contamination occurred. 6-10 hours labor if caught early, add CVT replacement if delayed.
Estimated cost: $1,200-2,000 (early catch), $4,000-6,000 (with CVT damage)
Engine Mount Failure (Especially Transmission Mount)
Common · medium severityTypical onset: 60,000-100,000 mi
Symptoms: Severe vibration at idle, especially in Drive, Clunking when shifting from Park to Drive or Reverse, Excessive engine movement visible when accelerating, Vibration through steering wheel and floor
Fix: Front and transmission mounts are undersized for the CVT's characteristics and fail prematurely. Transmission mount is the worst offender. Replace all three engine mounts as a set for best results. 2-3 hours labor.
Estimated cost: $400-700
Hood Latch Failure (NHTSA Recall)
Occasional · medium severitySymptoms: Hood pops open while driving, Hood not latching properly on first attempt, Secondary latch not engaging, Hood flutter at highway speeds
Fix: Factory hood latch secondary mechanism fails. Covered under recall (NHTSA 18V-134), dealer replaces latch assembly. If not done yet, get it done — hood flying up at speed is obviously dangerous. 0.5-1 hour labor, free under recall.
Estimated cost: $0 (recall)
Fuel Gauge Sending Unit Failure
Occasional · low severityTypical onset: 80,000-130,000 mi
Symptoms: Fuel gauge reading empty when tank is full, Erratic gauge movement, Gauge stuck on full, Check engine light with P0462 or P0463
Fix: Fuel level sensor in tank fails. Requires dropping fuel tank to replace sending unit. More annoying than dangerous but can leave you stranded if you trust a bad gauge. 2-3 hours labor.
Estimated cost: $350-600
Hard pass unless heavily discounted — the CVT and engine failures are expensive, common, and often happen just outside warranty coverage, making this one of the riskiest used sedans in its generation.
