7known failure points
350NHTSA owner complaints
3safety recalls
$5,000worst-case single repair
Cheap to buy, expensive to keep — the CVT is a ticking clock
Every documented failure, earliest first
Ordered by the mileage the problem typically appears. VERY HIGH
confidence means it's tied to a documented NHTSA recall, and 2 of these are rated Critical.
30k–70k mi● Watch$700–$1,100MODERATE
AC compressor clutch failure / weak cooling
How to catch it: Run AC year-round for 10 minutes weekly to keep seals lubricated; catch a whining clutch early before it grenades the compressor.

40k–80k mi● Watch$250–$500MODERATE
Front strut mounts and sway bar end links clunking over bumps
How to catch it: Replace end links with Moog K750168 as a cheap DIY before spending money chasing a phantom strut noise.

50k–90k mi● Plan$900–$1,600MODERATE
MR18DE timing chain rattle on cold start (tensioner wear)
How to catch it: Use only 0W-20 full synthetic on strict 5k intervals; a brief cold rattle is common, a sustained one means the tensioner is going.

60k–100k mi● Critical$3,500–$5,000MODERATE
JATCO CVT-7 (RE0F11A) judder, shudder, and complete failure — the defining defect of this car
How to catch it: Change CVT fluid with genuine Nissan NS-3 every 30k miles (Nissan says 'lifetime' — ignore them); if it shudders in traffic, get to a dealer while any extended warranty still applies.

60k–100k mi● Watch$300–$500MODERATE
Wheel bearings (particularly rear) howling above 40 mph
How to catch it: Listen for a drone that changes with steering input during test drive — a howling bearing is a bargaining chip, not a dealbreaker.

70k–120k mi● Critical$1,200–$2,200MODERATE
CVT valve body / stepper motor causing hesitation, whine, and erratic RPM
How to catch it: A fluid + valve body service is a fraction of a full replacement — do it at the first sign of hesitation between 40–60 mph.

80k–130k mi● Plan$200–$1,200MODERATE
O2 sensors and P0420 catalytic converter efficiency codes
How to catch it: Replace the downstream O2 sensor first (~$80 part) before assuming the cat is dead; often clears the code for years.
