How to interpret the counts
Complaint totals are not failure rates
A popular or older model can accumulate more complaints simply because more vehicles exist and have spent longer on the road. The categories above aggregate the counts embedded in each model year's leading issues. Use recurrence across years and severity signals to decide what to inspect; use the VIN and a mechanical inspection to judge one car.
Source trail
Where this Kia Soul data comes from
VinExposed combines model-level research with the vehicle-specific history you get from a VIN. Reliability scores and complaint patterns come from Auto Reliability Index's Kia Soul research, which analyzes NHTSA records and independent repair data.
Recall counts describe a model year, not the repair status of one car. Confirm the exact VIN with the official NHTSA recall lookup and a vehicle-history report before buying.
