Concentration in one or two component groups is the classic signature of a systemic defect; a flat distribution usually reflects normal aging, warranty complaints, or isolated build-plant variability.
NHTSA currently has 7 investigation files overlapping the 2020 Q50. Owners comparing this cohort against neighboring years should pair the counters above with the complaint-by-year trend on the parent model page — a spike in a single year often tracks to a platform refresh, a new transmission supplier, or an updated ECU calibration.

20250822ENGINE
Recently, the turbochargers on my vehicle failed prematurely and had to be replaced. Shortly after this repair, and with the vehicle still under 60,000 miles, the engine exploded and failed while driving. This incident posed a severe safety hazard not only to me but to other drivers and pedestrians as I lost propulsion and had to swerve to the shoulder to avoid oncoming traffic. Fortunately, no one was injured, but the sudden failure could have led to a much worse outcome as not only did it fail but hot oil and coolant both poured out of the hole in the engine creating a hazard. I believe this failure is not only unacceptable for a vehicle with such relatively low mileage, but it may indicate a systemic or design flaw, particularly if turbo and engine failure is a recurring issue among other owners of this make and model. I am aware of Infinitiâs current engine recall for select vehicles for premature engine failure and would like to know should this be extended to Q50 model.
