Fuel economy data from fueleconomy.gov (EPA / U.S. Dept. of Energy). Annual cost based on 15,000 mi/yr at 55% city driving and current fuel prices. MPG is U.S. gallons; L/100km converted. Ranges reflect the 6 tested variants for this model year.
Engine-related complaints make up the largest share of what 2017 Q50 owners report, with recurring accounts of oil consumption, oil burning, stalling, and white smoke from the rear of the vehicle, several owners describe these symptoms appearing well before high mileage. Turbo and broader engine system failures also appear across multiple reports. The electrical system draws the next-highest complaint volume, and a specific pattern stands out: owners report the passenger seat occupant sensor triggering fault codes that cause the passenger airbag warning light to illuminate, with at least some dealers confirming the sensor reads the seat as unoccupied even when someone is sitting there. Seat-related complaints, which rank third, overlap with this sensor issue. A handful of owners also describe persistent brake grinding or rattling that remained unresolved after dealer service.

By System
The 2017 Infiniti Q50 has 5 recalls, the most serious being a driveshaft that can fatigue and break, causing sudden loss of drive power or allowing the vehicle to roll away when parked without the parking brake applied.
On the fuel and engine side, certain Q50s with the 2.0L engine have a software error in the fuel pump control module that can allow the main tank to run too low to supply the engine, causing a stall while driving. There are also two airbag concerns: the driver's frontal airbag inflator can crack during deployment and fail to properly inflate the bag, and the passenger seat sensor that determines whether the front passenger airbag should deploy may not function correctly, leaving the passenger without proper airbag protection in a crash.
