Horn not sounding on 2015 WK2! Big time safety issue: when driving would hit horn and no sound INITIALLY.
After three or four hits, the horn would then sound. So when depressing certain areas of the steering wheel center the horn would not sound, other areas of the steering wheel it sounds.
So it wasn't a full failure, but highly unreliable and annoying, and the one time you need instantaneously horn sound, like running into somebody, your in trouble.
Resolution: Took it to dealer and they replicated the problem. They ordered a new drivers side air bag w/assembly, apparently the horn is part of this assembly. (Note: took about 4 wks to get parts from corporate and about 2 hrs to install)
With new air bag parts, the horn now works anytime it is touched as expected. All under warranty. Happy again.
Hope this helps others...
