How it compares in its class

Percentile ranks against other compact cars in the catalog.

Reliability: better than 9% of compact cars
Longevity: better than 27% of compact cars
Running costs: better than 100% of compact cars
Value retention: better than 85% of compact cars

Which of these numbers are measured

What stands behind each score for this car:

Reliability 63: from NHTSA recalls and complaints, divided by approximate units sold so it is comparable between models.
Longevity 74: an estimate from powertrain and brand record. No 200,000-mile population exists for a 2011 car yet, so this is a prior, not evidence.
Maintenance 90: repair-cost data where we have it for this model, otherwise a mechanical-complexity estimate from engine size, cylinder count and drivetrain.
Safety 67: NHTSA crash testing blended with IIHS awards.

Common questions

What goes wrong with the 2011 Honda Civic CNG?

Owners have filed 166 complaints with NHTSA for this model-year, and air bags is the most reported area with 37 of them (22%). No recalls are on record for it.

Is the 2011 Honda Civic CNG reliable?

AVOIR scores its reliability 63/100 (average) from NHTSA recall campaigns and complaint density, adjusted for how many were sold so a popular model is not penalised for having more owners.

How long will a 2011 Honda Civic CNG last?

AVOIR scores its longevity 74/100, 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.

Should I buy a 2011 Honda Civic CNG?

AVOIR's read: be careful, because the numbers are mixed and the complaint record is worth reading before you commit. Its overall ownership score is 67/100. Condition, mileage and service history still matter more than any score, so get a pre-purchase inspection on the specific car.
