Our Data Journalism Methodology

CarCodeFix is a data journalism platform that aggregates and analyzes real owner experiences from automotive communities. Here's how we transform thousands of discussions into actionable repair insights.

📡Step 1

Data Collection

We scan 50+ automotive communities including Reddit, dedicated forums, and YouTube

🔍Step 2

Data Extraction

Pattern matching identifies OBD codes, parts, costs, mileage, and symptoms

📊Step 3

Clustering

Similar issues are grouped by vehicle, problem type, and solution approach

📝Step 4

Analysis

We synthesize findings into comprehensive repair guides with statistics

🌐Data Sources

  • Reddit automotive communities (r/MechanicAdvice, r/Cartalk, brand-specific subs)
  • Dedicated automotive forums (model-specific communities)
  • YouTube repair video comments and tutorials
  • NHTSA complaint database for safety-related issues

🔤Text Analysis Pipeline

  • OBD code extraction using pattern matching (P0xxx, B0xxx, C0xxx, U0xxx)
  • Cost extraction from mentions like "$150", "$1,200" with context analysis
  • Mileage parsing from "85k miles", "100,000 miles" formats
  • Part and symptom identification using automotive vocabulary patterns
  • Sentiment analysis to gauge owner satisfaction with repairs

Solution Verification

  • [SOLVED] tag detection in post titles and updates
  • Follow-up analysis: "fixed it", "that worked", "problem solved"
  • Community validation through upvotes and reply patterns
  • Cross-referencing solutions across multiple sources

📈Statistical Analysis

  • Repair cost distribution with min/max/average calculations
  • Mileage occurrence patterns (when problems typically appear)
  • Success rate analysis for different repair approaches
  • DIY vs professional repair tracking
  • Trend analysis over time (increasing/decreasing problem frequency)

🛡️Quality Assurance

  • Minimum data threshold: 5+ owner reports before publishing
  • Source diversity requirement: data from multiple communities
  • Spam and bot filtering using automated detection
  • Confidence scoring for extracted information
  • Regular updates when new data becomes available

Transparency Commitment

We believe in full transparency about our process. Our content is created by analyzing real owner discussions - we don't fabricate data or invent solutions. Every statistic can be traced back to actual community discussions. When we don't have enough data for confident analysis, we clearly indicate this with a "Preliminary Data" label.

Human Expert Review

While our data pipeline is automated, high-traffic articles undergo review by certified mechanics and automotive professionals. We partner with ASE-certified technicians through Upwork to verify technical accuracy of our most-viewed content.
