What the numbers tell you

Understanding the 2001 Hyundai Sonata complaints

Which systems appear most often?

The largest component group is structure: 71 entries, or 24.2% of classified component entries. Next is airbags: 49 entries, or 16.7% of classified component entries. A complaint can name several components, so these percentages describe the entries in the file, not the percentage of vehicles affected. Only the leading component groups are displayed.

At what mileage were problems reported?

The median reported mileage is 86,000 miles, based on 137 complaints with usable mileage (66.8% of the 205 complaint incidents). Half of those reported mileages are at or below the median and half at or above it. This sample excludes missing or unusable mileage and does not predict when another vehicle will develop a problem.

Use these patterns to prepare questions about a particular vehicle's service history. Complaint reports describe submitted experiences; they do not establish the cause, repair cost, or condition of every 2001 Hyundai Sonata. Read the symptom groups below alongside the source documents and a VIN-specific recall check.

Cluster 3 of 32001 Hyundai Sonata

Each complaint is assigned to the first matching keyword group, even if it mentions several symptoms. Only the leading published groups are shown. Unmatched reports and other groups remain in the total, so these percentages need not add to 100%. A keyword match can miss context; it is not an owner quotation or proof of a defect.
