Reliability, what owners report, and what it costs to keep.
AVOIR's read: a solid ownership case with specific caveats below.
Owners have filed 36 complaints with NHTSA about the 2011 Infiniti M37, and it carries no recalls. These are owner allegations rather than confirmed defects, but the pattern of what people complain about is the most useful signal a used buyer has.

What stands behind each score for this car:
Owners have filed 36 complaints with NHTSA for this model-year, and power train is the most reported area with 12 of them (33%). No recalls are on record for it.
AVOIR scores its reliability 89/100 (excellent) from NHTSA recall campaigns and complaint density. That figure is a raw complaint count, not yet adjusted for sales volume, so a high-volume model scores worse than it deserves.
AVOIR scores its longevity 81/100, but that figure is an estimate built from the powertrain and the brand's record, not a measurement. A 2011 car has no 200,000-mile population to observe yet, so treat it as a prior rather than evidence.
AVOIR's read: worth a look, because a solid ownership case with specific caveats below. Its overall ownership score is 72/100. Condition, mileage and service history still matter more than any score, so get a pre-purchase inspection on the specific car.
