•Pull the dipstick cold and warm, check for milky or frothy oil indicating coolant intrusion; walk away if found
•Listen specifically for turbo whirring or whistling at idle and under boost during test drive, early turbo wear is common even below 50,000 km
•Run a full NHTSA VIN check and confirm the adaptive steering recall, airbag sensor recall, and driveshaft recall have been completed
•Request complete oil change service records, irregular or extended oil intervals are a direct predictor of turbo failure on this engine
•Scan with OBD-II reader for pending or stored fault codes across engine, transmission, airbag, and steering modules before agreeing to purchase
•Inspect the serpentine belt visually for cracking or glazing and ask for documentary proof of replacement; budget for immediate replacement if history is unknown
•Confirm whether the car is the base 3.0t (300hp) or Red Sport 400 (400hp) tune, since the higher-boost Red Sport tune runs the turbos harder

Twin Turbos (both units)
Inspect for shaft play and listen for whirring/whistling; budget for replacement or install BOV kit proactively

Serpentine Belt
Replace if no documented history; do not skip, failure causes cascade damage

Coolant System / Head Gasket Area
Pressure test cooling system and check oil for contamination before purchase and at each service

Steering – Automated/Adaptive Steering
Loss of steering control due to fault in the automated steering system on 2014-2016 Infiniti Q50 vehicles, increasing risk of crash.
Air Bags – Occupant Classification Sensor
Faulty occupant classification sensor may cause airbag not to deploy correctly in a crash, increasing risk of injury to occupants.
Powertrain – Driveshaft/Driveline
Driveshaft may fracture on certain 2014-2018 Q50 vehicles, potentially causing loss of vehicle control and crash risk.

The base 300hp tune and the Red Sport 400hp tune share the same turbos, oiling system, and known failure modes, so the reliability gap between them comes down to boost level rather than a hardware revision. A Red Sport driven hard sees more turbo stress than a base 3.0t, but a neglected base car can fail just as easily. Prioritize oil change history and any evidence of a factory blow-off valve delete or aftermarket BOV installation over chasing the higher horsepower figure. If choosing between two similarly priced examples, the one with denser service records and a lower boost tune is the safer buy, not necessarily the one with more power.
