For the 2016 Infiniti Q50, engine and steering complaints make up the largest share of what owners report. On the engine side, owners describe a range of failures including turbocharger oil leaks accompanied by heavy smoke, sudden loss of power with the check engine light illuminating, and coolant mixing with oil due to what owners describe as a porous engine block, the latter leading to bearing failure in some cases, sometimes at relatively low mileage. Electrical issues also come up, with a handful of owners reporting complete loss of vehicle power while driving, sometimes after earlier signs of battery trouble. The airbag category draws a few complaints centered on the passenger seat occupant sensor failing and triggering the airbag warning light without any prior collision. Steering complaints round out the picture, though the reported symptoms there are less consistent across the group.

With Injuries
By System
The 2016 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.
Two recalls involve the fuel pump control module software, both affecting 2.0L-equipped models: incorrect software can allow the fuel level in the main tank to drop too low to feed the engine, and a separate but related issue can prevent fuel from transferring from the sub tank to the main tank. Either way, the engine can stall while driving. On the steering side, the Direct Adaptive Steering system can encounter an error at startup that alters steering responsiveness and turning radius, causing the vehicle to handle differently than the driver expects. There is also a passenger airbag concern: a fault in the passenger seat occupant classification sensor can cause the front passenger airbag to not deploy correctly in a crash, raising the risk of injury to that occupant.

What can fail
The fuel pump control software uses an incorrect pressure map, which may prevent the pressure regulator from opening. This can leave the main fuel tank too low, starving the engine of fuel and causing loss of power.
What the fix does
Dealers will update the Fuel Pump Control Module software to correct the pressure map.
