This article focuses on the seventh-generation Hyundai Sonata (LF) manufactured between 2014 and 2019. It provides fuse box diagrams for each year—2014, 2015, 2016, 2017, 2018, and 2019—showing where the fuse panels are located inside the car. You’ll also learn about the function of each fuse and relay through clear and straightforward explanations.
