Infiniti Q50 — the 10 years we've written up
2014–2023, side by side: what goes wrong on each, what the fix costs, and what they typically ask. 6 of the 10 carry a high-severity issue.
What this page is
These are the 10 Infiniti Q50 model years Kestrel has done the homework on — not every year Infiniti built one. A year that isn't listed here isn't a year we're warning you off; it's one we haven't written up yet. Ranking a whole model run would mean telling you about years we've never looked at.
Infiniti Q50 by year
How many owner complaints NHTSA holds. A big number usually means a lot were sold; the shape matters more than the total.
Year by year
Steering wanders over uneven pavement and feels loose or disconnected; alignment does not cure it — $0–$300 for an alignment or steering recalibration; $1,500–$3,500 if a steering component is replaced out of warranty
3.0t twin-turbo V6: turbocharger and engine failures documented on earlier years — $3,000–$7,000 for turbochargers; $10,000–$15,000 for a replacement engine
Engine computer can cut fuel and stall the engine after hard acceleration (recall) — $0 with the recall — verify it was performed
3.0t twin-turbo V6: the turbocharger and engine failures seen on 2018–2019 carry over — $3,000–$7,000 for turbochargers; $10,000–$15,000 for a replacement engine
3.0t twin-turbo V6 turbochargers fail; some engines follow with metal in the oil — $3,000–$7,000 for turbochargers; $10,000–$15,000 for a replacement engine
3.0t twin-turbo V6: turbocharger failure, then low oil pressure and engine knock — $3,000–$7,000 for turbochargers; $10,000–$15,000 for a replacement engine
VR30 twin-turbo: turbochargers fail into limp mode, coolant loss and overheating, engines replaced — $2,500–$5,000 per turbocharger; $8,000–$12,000 for an engine
Twin-turbo 3.0T cooling / oil maintenance — $200-$1,500
Direct Adaptive Steering (steer-by-wire) failures — $2,000-$5,000
Direct Adaptive Steering can lock, pull, or fail at startup — two recalls, five crashes in the record — $0 with the recall — verify it was performed; $1,500–$4,000 for DAS actuator or ECU replacement outside warranty
4 of these 10 have no high-severity issue in our write-up. That means we didn't find an expensive recurring fault — not that one cannot exist on the specific vehicle you're looking at.

This page covers the Infiniti Q50 in general. The Kestrel report covers the one you're looking at — the asking price against the market, the photos, the seller's description, and a BUY / NEGOTIATE / WALK AWAY verdict with a negotiation script.
