Is this an issue with the ecm,bcm or the pcm. Any advise would be great, thanks.

Any body or engine codes or dash codes?
What waring lights come on?
Real bright or dim light?
Bad ground/turn/tail/parking lights can cause feed back on dash stuff.
Also.
Have dealer check and run vin no. for tsb,s know problems on it.
