Data Sources & Methodology

Complaints: NHTSA Office of Defects Investigation consumer complaint database (2,569 records for this model). Public domain data, updated monthly.

Sales data: Not yet available for this model. Complaint counts are shown as raw numbers.

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 count. GOOD = 0.6x or below. Years less than 3 years old are marked TOO NEW (insufficient data).
