Electrical Issues + horn


Recommended Posts

So the other day I pull up to daycare to pick up my son. It's cold out so I decide to keep car running while I go inside to get him.

I open the door with key fob in hand and as I am getting out of the car, the horn starts blaring. It wont shut off. Turned car off, horn still on. Turned car back on then off and the horn finally died. So I chalk one down to WTF and move on.

The very next day I go to get in my car after work and the battery is dead. (2012 crew v6 AWD I bought 11mo ago). I jump the battery, the horn goes off again second I connect to battery. Jump it and go straight to dealer.

Dealer said switch that controls horn and dash instrument in center cluster. Anyways that drained the battery, they replace defective switch and battery.

I come by to pick up car. I'm inside car and as I leave the car to get service paperwork from Dealer, the horn goes off again just as it did the other day. This time dealer was right there to see it. Then i tested panic button, just flashes lights, no horn. 15min later, panic works fine.

To top it all, car doesn't detect key fob after car running and can drive car without key fob in the car, it is supposed to shut off engine in that scenario.

Has anyone had any of these issues?
