Data Sources & Methodology
Complaints: NHTSA Office of Defects Investigation consumer complaint database (10,783 records for this model). Public domain data, updated monthly.
Sales data: US annual vehicle sales from goodcarbadcar. Coverage: 64% of model years have sales data. Total US sales: 1,813,845.
Rate calculation: Complaints per 10,000 vehicles sold = (complaint count / US annual sales) x 10,000. This normalizes for sales volume so high-volume models like Civic or Camry aren't unfairly penalized.
Year classifications: AVOID = 1.5x+ the model's median complaint rate. GOOD = 0.6x or below. Years less than 3 years old are marked TOO NEW (insufficient data).
