How it compares in its class

Percentile ranks against other midsize & large cars in the catalog.

Reliability: better than 44% of midsize & large cars
Longevity: better than 56% of midsize & large cars
Running costs: better than 72% of midsize & large cars
Value retention: better than 22% of midsize & large cars

Which of these numbers are measured

What stands behind each score for this car:

Reliability 81: from NHTSA recalls and complaints. This one is a raw count: we do not have a sales figure for this model, so a high-volume car looks worse here than it should.
Longevity 78: an estimate from powertrain and brand record. No 200,000-mile population exists for a 2013 car yet, so this is a prior, not evidence.
Maintenance 80: repair-cost data where we have it for this model, otherwise a mechanical-complexity estimate from engine size, cylinder count and drivetrain.
Safety: no score. NHTSA crash testing thins out for older vehicles and we would rather show nothing than guess.

Common questions

What goes wrong with the 2013 Infiniti G37?

Owners have filed 63 complaints with NHTSA for this model-year, and air bags is the most reported area with 31 of them (49%). No recalls are on record for it.

Is the 2013 Infiniti G37 reliable?

AVOIR scores its reliability 81/100 (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.

How long will a 2013 Infiniti G37 last?

AVOIR scores its longevity 78/100, but that figure is an estimate built from the powertrain and the brand's record, not a measurement. A 2013 car has no 200,000-mile population to observe yet, so treat it as a prior rather than evidence.
