I have a 2011 Sonata GLS with power option and over the least week noticed an issue with the brake pedal. The car stops just fine, but after 15 minutes or so of driving when i go to depress the pedal lightly i am feeling someting coming off of the pedal. I would compare it to if a door was creaking, but no noise just the funny feeling you get. I am having as i said before no brake issues what so ever and there is no noise coming from the brake pedal itself. I can really feel it as i am entering into my parking garage and have to slow doen for speed bumps and when pulling into a spot; any thoughts?
