AI vs methodology

Why use Norjin if AI exists?

AI answers questions

AI can use different data and its answers can depend on how a question is asked.

Norjin evaluates vehicles

Norjin organizes possible risks into a comparable format. Its AI-assisted score is a starting point for research, not a verified prediction of what will happen to a particular car.

Worked example

From raw findings to a score

Step 1 — Component ratings
Engine30% · 68/100
Transmission20% · 72/100
Electrical20% · 74/100
Suspension & brakes15% · 84/100
Body & interior15% · 88/100

In this illustration, the weighted average is 75 points. These weights are examples, not live scoring rules.

Step 2 — Issue deductions
Timing chain tensioner wear
Common · 60–120k km
−6
Water pump / thermostat leak
Common · 80–140k km
−4
Carbon build-up on intake valves
Occasional · 100k+ km
−2
DSG mechatronic faults
Rare · 120k+ km
−1

Illustrative deduction = −13 points. These penalties are not derived from a verified per-model sample.

Step 3 — Final index
75 − 13 = 62

Example calculation only; live Norjin scores are not calculated using this displayed formula.

Step 4 — Rating class
Average — budget for maintenance

85–100 Excellent · 70–84 Good · 55–69 Average · 40–54 Weak · below 40 Poor.

What it means

In this hypothetical case, ask for evidence of timing-system and cooling-system maintenance before buying.

Methodology

How the scores are built

Norjin's 0–100 number is an AI-assisted risk assessment, not the percentage of cars that will avoid a breakdown. Use it as a starting point for inspection, not a guarantee.

01 / Scope

Specify the vehicle

A model name alone can cover different engines and gearboxes. Add the year, engine and transmission when you know them; otherwise the assessment may be too broad.

02 / Evidence

Inspect the references

Reports suggest regional sources, but a listed source does not prove a particular defect applies to your exact car. Inspection results, recalls and owner posts each have different limitations.

03 / Interpret

Read the score cautiously

The index is AI-assisted and not calculated from a published, fixed set of source weights. Per-vehicle sample sizes, observation periods and error margins are not currently available.

Data sources
Official registries & recalls
Inspection statistics
Road service & breakdown data
Consumer agencies & magazines
Owner forums & communities
Technical service bulletins
Regional parts & labour rates
Model-specific engineering data

Source lists are starting points, not a traceable dataset of every observation behind the number. Forum posts overrepresent problems; recalls and technical notices do not tell you how common a fault is. No independent validation of the index against future breakdowns is currently available.

Norjin index, not a failure probability

A score of 87/100 does not mean an 87% chance of reliability. The Norjin index is an AI-assisted assessment, not a measured failure rate or a validated prediction. Official inspection statistics, when available, are shown separately and do not validate this score. Do not use the score alone to decide whether to buy.
