I had purchased my car over a weekend and in less than 2 days, on my way to work, I noticed that the horn volume and reliability was severely diminished to the point where you can’t hear it if you have the windows rolled up inside the vehicle, and/or dsnt work at all. I used my warranty to replace the horn and have the dealership take a look at it. they recognized that it was a problem but even after replacing the horn, the issue still persisted.
