NHTSA safety recall · Dec 19, 2018
NHTSA campaign data lists the defect, safety consequence and manufacturer remedy. The manufacturer filing lists 71,653 potentially affected units across the complete campaign.
Confirm who pays before authorizing work
A recall remedy follows the campaign and VIN eligibility. A service bulletin provides diagnosis or repair instructions; it does not by itself promise payment. Manufacturer warranty extensions and support programs have their own conditions.
Compare recalls, bulletins and warranty extensions →Keep a current problem separate from future coverage
These files do not supply a shop quote. Ask for a diagnosis and written estimate, then check recall remedies or existing coverage. A new vehicle service contract generally excludes pre-existing conditions.
Prepare a useful description for the mechanic →Each file retains its original source review date. Historical remedy wording can change; check the current manufacturer notice and NHTSA VIN lookup for your vehicle. The separately dated NHTSA counts elsewhere on this page use a different dataset and scope.

What can the data tell you about 2015 Kia Optima?
No model-specific individual-repair price keys are retained for Kia Optima in this library. Generic parts and labor estimates, public records and separate annual cost references may still be available.
An unmatched specification is an information gap. Do not borrow an engine or drivetrain from another year.
Recall and communication counts describe records. They cannot establish a breakdown probability or current VIN status.
Price-key audit reviewed October 12, 2026; EPA source snapshot 2026-08-07. Individual-repair ranges and annual repair-budget references are different datasets.
