Has anyone had their horn beep while driving down the road? This has happened to me three times in the last month. When it happens, the horn will give a single beep and then ramain silent for a few days to a week. At first I didn't realize it was coming from my car. I thought it was someone beeping at me.

if its at the same speed. its your setting for the overspeed chime

Your horn is beeping while your driving? That's a new one for me. Has your car ever had front end damage? Possible grounding issue? Hope it's not your BCM acting up.

Yep is it horn honking or a tone beeping from inside the car?
