2015 Kia Optima Hybrid recalls & complaints
Source: NHTSA, updated daily. Last checked 2026-10-18. Recalls apply to specific VINs — run your VIN to confirm.
4 safety recalls, most serious first
1. Fuel system
What's wrong, in plain English: Fuel lines, tank or pump. Fuel problems usually mean a leak, and leaks mean fire risk. The high pressure fuel pipe that connects to the fuel pump outlet may have been damaged, misaligned or improperly torqued during the engine replacement procedure, possibly causing a fuel leak.
What could happen: A fuel leak in the presence of an ignition source can increase the risk of a fire.
The fix: Kia has notified owners, and dealers will inspect and replace the fuel pipe, as necessary, free of charge. The recall began January 17, 2019. Owners may contact Kia customer service at 1-800-333-4542. Kia's number for this recall is SC172.
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 2015 OPTIMA HYBRID.
- Book a repair at any authorized Kia dealer. Quote NHTSA campaign 18V907000 (manufacturer code SC172).
- 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.
