2.0L Turbo (M274) - GT/Sport
Petrol
While accelerating gently, feel for any hesitation or 'flutter' from the turbocharger, as the M274 engine's induction system can occasionally develop minor boost-related quirks.
Check the Direct Adaptive Steering (DAS) system by navigating a few roundabouts; ensure there is no unusual feedback or warning lights, as the electronic steering setup is complex.
While parked on a flat surface, listen closely to the engine idle; a faint rhythmic ticking is often normal for direct-injection engines, but distinct rattling could suggest the timing chain tensioner requires a check-up.
Check the infotainment system by cycling through the dual-screen interface; ensure both displays respond promptly, as the secondary screen can occasionally lag on older units.
Consider a full transmission fluid service to ensure smooth shifts from the 7-speed automatic.
Recommended inspection of the cooling system, specifically the water pump and thermostat housing.
Standard time to assess the suspension components, particularly the control arm bushings, which often show wear on heavier sedans.
Keep up with strict 10,000km oil change intervals to keep the turbocharger and variable valve timing components happy.
Ensure the premium fuel (95 or 98 RON) is used consistently to prevent carbon buildup on the intake valves.
Check the battery health regularly, as the electronic features in the Q50 are quite sensitive to voltage drops.
Verify that the cabin air filter is replaced annually to keep the dual-screen interior climate systems running efficiently.
Monitor the tyre pressure closely, as the run-flat tyres often fitted to these models can mask alignment issues if not kept at the correct PSI.
Estimated repair costs if issues arise
While not an immediate failure point, it's worth keeping in mind that on the M274 engine, the tensioner may eventually need replacement as part of preventative maintenance. It's a proactive measure to ensure long-term engine health.
If the car is equipped with the drive-by-wire steering system, it is quite sophisticated. Should it require recalibration or sensor attention in the future, it is best handled by a specialist who understands Infiniti's specific diagnostic software.
Depending on the car's history, you might eventually need to budget for some attention to the turbo wastegate. If you notice a loss of boost power later down the road, this is a common component to inspect.
