Infiniti Q50 Problems by Year

The Infiniti Q50 is a sleek, handsome executive saloon that was Nissan’s luxury division's attempt to challenge the BMW 3 Series and Mercedes C-Class. It offered a high level of standard equipment, a comfortable ride, and uniquely aggressive Japanese styling. In the UK, it struggled to gain a foothold due to the dominance of German brands, making it a rare and depreciated used buy. The most controversial feature was the "Direct Adaptive Steering" (steer-by-wire system) on certain models, which felt artificial to driving enthusiasts. Reliability is generally robust, especially the Mercedes-sourced 2.2-litre diesel, making it a left-field bargain for buyers wanting a distinctive, reliable executive cruiser.

Buying Tips for the Infiniti Q50

  • If the car has "Direct Adaptive Steering" (steer-by-wire), test it extensively; ensure there are no warning lights, as repairs are highly specialized.
  • Check the dual-screen infotainment system, which is known to be laggy and can occasionally freeze or reboot unexpectedly.
  • On the 2.2d (Mercedes-sourced diesel), check for smooth power delivery and ensure the DPF is not blocked from short city trips.
  • Listen for suspension knocking, particularly from the front anti-roll bar drop links.
  • Inspect the interior trim; while luxurious, the leather on the driver's seat bolsters can wear prematurely.
  • Ensure the automatic gearbox shifts smoothly without hesitation, particularly when downshifting under load.
