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 Infiniti’s current engine recall for select vehicles for premature engine failure and would like to know should this be extended to Q50 model.

Reading this record
No unusual pattern of severe incidents in the complaint record.
Complaint counts track how many cars were sold and how long they have been on the road as much as they track quality. A common model from 2013 has had a decade to accumulate reports; a rare one from last year has not. The signal worth weighing is in the severity columns, in whether the same component keeps appearing, and in whether the manufacturer eventually opened a recall for it.
Most recent recall on file: none. Source: NHTSA Office of Defects Investigation.
