    Anyone have any idea what can cause this?Just bought car 1 month ago not familiar with what can usually cause this.It just blinks on and off real quick maybe once or twice on a long drive.Oil life still at 75% life remaining fluid levels good,checked gas cap.Seems to be running fine.

    Take it to a parts store and have it scanned for codes. It will point you in the right direction. The computer is trying to tell you something. Just post the code(s) here and we can help out.

    does it flash when your flooring it? could be misfires aka needs a tune up, or the cat is clogged up. parts store for a free scan, autozone is free and easy to deal with if you got one near by.

    No happened once while sitting in parking lot.Also happened once while turning a corner after a 4 way stop.I recently replaced the interior lights with led's read that could trigger it to.So I removed them all and put back factory ones.I'll swing by Auto Zone to be safe.I will post codes though,thanks for your help.

    if its just the service vehicle message you wont be able to get a code at autozone. I have no idea what is bringing mine up. No cel light just the message in the dic. My dealer said it could be a number of things that needs a tech 2 to actually see it.

    Scanned min gxp today and got a U0073 control module communication bus off code.Sounds like it could be several things.From everything I'm reading as well it's something GM tech may need to see to figure out.$$$$$$$$$$ ouch.
