3NHTSA owner complaints
0safety recalls
$5,500worst-case single repair
The last of a dying breed — a genuinely comfortable, V6-powered four-door 'four-door sports car' that Nissan killed off right after this generation, making it a swan song rather than a smart long-term bet.
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.
0k–15k mi● Watch$0–$400MODERATE
Early electronics gremlins — infotainment freezes, gauge cluster lag on electronic coolant temp display, occasional CD/media module glitches
How to catch it: Update infotainment software at the dealer at every visit — most of these early quirks are patched via software, not hardware swaps.

20k–50k mi● Watch$800–$1,800MODERATE
Panoramic sunroof seal/glass integrity issues (rare but documented explosive shattering reports across Nissan panoramic roofs)
How to catch it: Avoid slamming doors with windows/sunroof fully closed and have the roof drain channels inspected yearly — pressure buildup is the usual culprit.

60k–90k mi● Critical$150–$5,500MODERATE
CVT (Jatco) fluid degradation leading to shudder, hesitation, or judder under load
How to catch it: Do a full CVT fluid change (not the 'lifetime fluid' myth) every 30k miles using genuine NS-3 fluid — this single habit is the difference between 200k miles and a $5k bill at 90k.

70k–100k mi● Plan$300–$600MODERATE
Front brake rotor warping/pulsation, common on heavier Maxima trims with the sportier suspension tune

80k–120k mi● Watch$300–$600MODERATE
VQ35DE oil consumption creeping up, occasional intake valve carbon buildup (direct injection)
How to catch it: Run a can of quality top-tier gas system cleaner every 5k miles and check oil monthly — DI engines build carbon faster than port-injected ones.
