Problem with my Hyundai Sonata 2013 GLS taillights/brake lights are not turning off. The car is off, key out of the ignition, lights switched off and foot not on the brake and lights are remaining on. They stay on throughout the night and day. The worst time is while driving , they remain on as if I'm driving with my foot on the brake. This is ridiculous. I am left to figure it out on my own as there is no recalls and I refuse to pay the dealership for something that should clearly be a recall. With hundreds if not thousands of people reporting this issue with Sonatas from modules dating back that I can tell from 2007 to current. I refuse to get this car agai and as soon as I can sale it consider it sold!.
