Ok I did a search and came up with nothing.

On 3 occasions my horn has stuck on.

The first 11:30 at night hit the key fob and boom the horn sticks on. After about 4 minutes of it blareing I hit the horn on the wheel and it went off.

The second, driving down the highway and the horn just comes on. Same, hit the wheel and it went off.

Third again after depressing the key fob.

What the hell is going on here?

 

Its a defective Horn relay its likely not actuating correctly so a good bump or actuating it can cause it to stick.. its a dealer item and will be covered under warranty...

 

A lot of times, they replace the whole steering wheel altogether. Had that same problem with my previous car but it was worse. The horn got stuck on and we ended up pulling the wire on the horn itself. The dealer went ahead and replaced the entire steering wheel. So hopefully you aren't too attached to your current one...

 

I kinda thought it would be a dealer item and no I am not attached to the stock wheel..lol.

I need to get this taken care of soon before my neighbors kill me.

 

you could always pull the fuse.

 

At first I would have said there was something wrong with the button on the steering wheel, or in the steering column, but you described two occasions where it started beeping after hitting the key fob.. so I have to assume its a bad relay..

Find the relay or fuse and pull it out.. It should stop the noise until it can be replaced. The fuse may be running more than just the horn relay, but both should be under the hood..
