Hyundai Sonata and Kia K5 Sedans Recalled to Fix Fire Risk

The problem is caused by a faulty check valve that can allow air into the fuel tank, causing it to expand and come into contact with hot exhaust components. If this happens, fuel could leak and start a fire. Drivers may first notice a popping sound coming from the area of the fuel tank, an illuminated check engine light, a rough-running engine, an engine that won’t start, or a fuel odor.

To fix the defect, dealerships will replace the faulty check valve, inspect the fuel tank and replace it if necessary, and provide a software update. As with all recalls, this repair will be free of charge.

Hyundai has an ownership stake in Kia, and both companies share parts and vehicle designs. In this case, both vehicles used the same faulty check valve and hose assembly from the same supplier. In recent years, both brands have occasionally announced similar recalls.

According to documents provided to the National Highway Traffic Safety Administration, both automakers have reported leaks but no fires, crashes, or injuries related to the problem.
