It doesn't sound like a car or a truck. Mine sounds like a dying seal.

Anyone else notice this? Maybe I'll put some air horns on that bitch.

 

haha you have dual horns. One of them could have gone bad. Have a dealer check it out.

 

Funny you mention that... I used the horn in mine for the first time in probably 6 months just the other day and I didn't remember it sounding like it did. It does sound like something between a car and a truck but it got the moron in front of me moving, though, so it did its job.
