How it compares in its class

Percentile ranks against other pickup trucks in the catalog.

Reliability: better than 51% of pickup trucks
Longevity: better than 62% of pickup trucks
Running costs: better than 95% of pickup trucks
Value retention: better than 91% of pickup trucks

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 79: an estimate from powertrain and brand record. No 200,000-mile population exists for a 2001 car yet, so this is a prior, not evidence.
Maintenance 86: 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 2001 GMC Sonoma?

Owners have filed 90 complaints with NHTSA for this model-year, and structure is the most reported area with 26 of them (29%). There is 1 recall on record. Check any specific car against its VIN before buying.

Is the 2001 GMC Sonoma 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 2001 GMC Sonoma last?

AVOIR scores its longevity 79/100, but that figure is an estimate built from the powertrain and the brand's record, not a measurement. A 2001 car has no 200,000-mile population to observe yet, so treat it as a prior rather than evidence.
