Six times horn has stopped working. Had into dealer every time, sometimes they could duplicate, sometimes they could not. Their solution was to replace everything in the horn area electrical at a significant cost - with no guarantee that the problem would get fixed.

Found, and reported, that problem occurs when you adjust the steering wheel up to a higher position. Evidently wires (which ones unknown to dealer) are pinching and causing a short circuit. Solution which is not acceptable is to not move the steering wheel to adjust for a different driver.
