I have a 2010 La Crosse CX, tonight the horn started to blow like an alarm and the lights flashed with no one in it. Any idea what is going on?

Something is haywire with your security system. You will need to find someone to track down the problem. If you had a service manual you might be able to either pull the fuse or unplug the security module but you need to know where it is located
