Verbatim excerpts from NHTSA complaints, by component

Power train

2 reports
“2020 Infinity Q50 RWD- Issues with premature twin turbos oil leak. Issue occurred just 850 miles over the 70K mile warranty expired. Same issue as the 2018 model. Infinity USA refused to cover repairs. Repair quote was for $10K”

Engine

1 report
“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.”
