How AVOIR Scores Reliability

AVOIR · updated 2026-07-18

AVOIR scores every vehicle 0–100 across seven ownership factors — reliability, longevity, maintenance cost, depreciation, performance, efficiency, and safety — from transparent public and market data. Here's how the reliability score, the one most people search for, actually works.

Reliability: observed data, not surveys

Most "reliability ratings" come from owner-satisfaction surveys. Those are slow, subject to recall bias, and reflect how owners feel. AVOIR uses observed signals instead:

These roll into a single 0–100 reliability sub-score. Higher means fewer serious, frequent problems than comparable vehicles.

Longevity, cost, and safety

Reliability answers "will it break?" — longevity answers "how far will it run?", estimated from high-mileage survival data and a proprietary used-market resale panel. Maintenance and depreciation capture what ownership actually costs. Safety blends NHTSA 5-star crash ratings with IIHS awards.

Why we show our work

Every AVOIR score links to the data behind it — you can see exactly why a vehicle scored 61 instead of 74. No proprietary black box, no editorial mystery rating. Look up any make, model, and year on askavoir.com, or browse the most reliable used SUVs.

FAQ

How does AVOIR measure reliability?

From observed data — NHTSA recall counts, verified complaint density, and multi-year defect trends — combined into a 0–100 score, rather than owner-satisfaction surveys.

Is a higher AVOIR score better?

Yes. Every factor is scored 0–100 where higher is better — including cost factors like depreciation and maintenance, where a higher score means lower real cost.
