Owner-reported complaints filed with NHTSA, grouped by component

Data refreshed

Owner complaintsComplaints are reports submitted to NHTSA by owners and drivers. NHTSA does not verify most reports before publishing them, and a complaint does not establish that a defect exists. Volume is influenced by how many of a vehicle were sold, how long it has been on the road, and how much attention an issue has received.

Reports naming the engine itself — including stalling, misfires, oil consumption, cooling and internal engine components.

report

From owner reports, verbatim

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.

Higher-selling and older vehicles accumulate more reports. Counts are not failure rates and are not directly comparable between vehicles that sold in very different numbers.
