5known failure points
184NHTSA owner complaints
2safety recalls
$5,500worst-case single repair
A cheap-to-buy commuter appliance sitting on a CVT time bomb — buy it for the price, not for the peace of mind.
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 1 of these are rated Critical.
20k–60k mi● Watch$0–$150VERY HIGH
Brake light switch failure (subject of NHTSA recall) causing no-start and brake light malfunction
How to catch it: Confirm the recall (brake light switch contamination) was actually performed by VIN before buying — many used examples slip through uncompleted.
Source: documented (NHTSA recall)
40k–80k mi● Watch$300–$900MODERATE
Forward Emergency Braking / radar sensor false activations or failures behind the grille emblem
How to catch it: Keep the front emblem/sensor area clean and undamaged — even minor front-end bodywork can throw the FCA system out of calibration.
Source: owner-reported (12 NHTSA complaints)
50k–90k mi● Critical$3,500–$5,500MODERATE
CVT (Jatco JF015/JF016-derived Xtronic) shudder, whine, or catastrophic failure — often preceded by a 'loud pop' then stuck in reverse or limp mode
How to catch it: Change the CVT fluid (Nissan NS-3 spec only) every 30k miles regardless of what the 'lifetime fluid' sticker says — this is the single biggest lever you have.
Source: multi-source pattern (AI synthesis)
60k–100k mi● Plan$400–$800MODERATE
Front strut mounts and lower control arm bushings wearing, causing clunks over bumps
How to catch it: Have a shop check strut mounts at 60k during any other suspension work — cheap to bundle, annoying to do alone.
Source: multi-source pattern (AI synthesis)
80k–120k mi● Watch$200–$700MODERATE
Ignition/push-button start electrical gremlins tied to body control module or clock spring wear
How to catch it: If the horn or steering wheel controls get intermittent, diagnose the clock spring early before it fails completely and disables airbags/horn.
Source: owner-reported (8 NHTSA complaints)
