What to do
- Check whether your car is affected: enter your 17-digit VIN at nhtsa.gov/recalls. A recall covers specific VINs, not every 2012 OPTIMA HYBRID.
- Book a repair at any authorized Kia dealer. Quote NHTSA campaign 20V750000 (manufacturer code SC200).
- The repair is free. By US law, safety recall repairs cost the owner nothing, no matter the car's age or mileage.
- Manufacturer hotline: 1-800-333-4542.
- Buying this car used? Ask the seller for proof the recall was completed, or run the VIN yourself before paying.

2. Airbags
What's wrong, in plain English: The airbag system — the part that is supposed to protect you in a crash. In the event of a crash, the air bag control unit (ACU) may short circuit, preventing the frontal air bags and seat belt pretensioners from deploying.
What could happen: If the frontal air bags and seat belt pretensioners are disabled, there is an increased risk of injury to the vehicle occupants in the event of a vehicle crash that necessitates deployment of these safety systems.
The fix: Kia will notify owners. For model year 2011 Sedona vehicles, Kia will instruct dealers to verify the ACU part number and, if necessary, install an extension wire harness kit between the ACU Connector and the Vehicle Harness Connector. For all other affected vehicles, Kia will instruct dealers to install the extension…
