Horn failure. Sounded my horn at another vehicle and the horn continued to sound even after I took my had off of it. This continued on for about 10 to 15 minutes, including turning car on and off, until the point the horn completely died on it. Horn has intermittently worked on and off for about 2 years now. I was driving on a highway on I-55 southbound between California Ave and pulaski road in chicago. This is a major failure as it is a small car and larger vehicles (suvs/semi-trucks/etc. ) do not always see me. Makes vehicle very unsafe to drive.
