What this page shows
Everything below is an owner-reported complaint submitted to NHTSA about the 1994 Kia Sephia, grouped by the component NHTSA recorded on the report.

Complaints are reports submitted by owners and drivers to NHTSA. They are not verified and do not establish that a defect exists.
