A couple of days ago I'm driving and all of a sudden I get a series of warning lights and error codes on my dash. The error messages showed both the air suspension and HDC not working and the warning lights came on for the brakes and ASR. There was no change in how the vehicle drove. After I got home I turned the car off and came back a bit later and started it up. No error messages at all. Any ideas? Just an electrical issue? BTW, it is a 2003 RR HSE.

 

could be anything but get it checked out or else it might fail and leave you stranded.
