My 2005 Dodge Ram 1500 was in the garage and all of the sudden the horn started to honk. Put the key into the ignition and started it up and it quit but when turned off it would start to honk again. This went on for about 5 minutes and finally when I turned off the vehicle it quit doing it. But the first time was 6 months ago and the 2nd time was 2 days prior to this time time. You can hear that the locks are also trying to lock and that is the reason it makes me believe that it is a security issue with the vehicle. Anyone else have this issue and if so what was done to resolve the issue?

This doesn't sound like the same issue, as it honks continually and doesn't stop just after 3 beeps.

 

More people here discussed with some solution like the dealer replaced the relay or the power distribution center:
