2005 C6 throws up random warning, service soon, low fuel, anti-lock brakes abs lights, shocks inoperative, and more. Then you can shut it off and sometimes it will go away. And sometimes it will come back.

Possible Bad battery

Yup, sounds like a likely place to start! These cars are really dependent upon a good battery.
I'll vote battery also .My strategy is if the car sets for 7 days put a tender on it ,if stored in the winter disconnect .Also every few years I get a new battery and put the old battery in my wife's car .I don't fully explain this process to my wife but she gets excited that I'm concerned about her well being .She also believes the car runs much better after I change the oil .

Suggest you NOT disconnect battery if you have a GPS clock in there.
The GPS clock issue has nothing to do with long-term storage, indexing windows, reprogramming radio, or anything else like that. If you have a GPS clock, and maybe you don't, and your vehicle is less than a 2011 I believe, you will lose your clock permanently if you disconnect the battery from the system. Are you aware of the situation? If you have no GPS system or a more modern one in your Vette, then not to worry.Well Ted this has long been a debatable issue .I worked at Bowling Green and I asked engineering what were the thoughts pertaining to this issue .Yes it may require indexing windows and a couple other items but that's it .In some of the C5 and C6 owner manuals disconnect for long term storage is recommended .
2008 3lt with nav .
Every year since 2003 I drive my corvette from Maine to Florida and place it in a self storage near the Orlando airport .I disconnect the battery until I fly down a couple times a month connect the battery and away I go .I would guess my 08 has been disconnected 30 or more times and other than indexing no problems .
So your saying if someone changes out a battery or service requires a disconnect your clock is toast .Every one who owns a C5 or C6 on this forum has disconnect the battery for one reason or another .
I'm not egging on ya but please explain how you plan to replace the battery when it's time for replacement without disconnecting .
None taken ,so I will except possibly being half wrong .Not trying to get in the middle too much, but there are memory savers than can be plugged into the OBD2 port to save memory in the computers while changing out the battery.
Also I have read about problems with owners losing their clock after disconnecting the battery in certain model C6's. I believe there might be a post on this site about it.
Ok I'm done. No offense intended.
vett boy,
When was the last time you disconnected your battery on your C6? I am not trying to be facetious, just helpful. If you have done this since, say mid-to-late December 2018 to present, and you still have your GPS clock, then you are blessed because there are thousands of folks with C6's between 2005 and 2011 who have disconnected their battery and now have no GPS clock, and this includes those who have had GM dealer's do their disconnects before GM knew there was a problem. If you read up you will find that the problem was most probably caused by the Air Force, who controls all GPS satellites, changing the clock download signal to a higher "bit" value. I'm just trying to save you a major pain. I am going to attach here, a thread where you can read all about this on-going problem. Let us know what you think. Oh, and LLC5 has a post just below that indicates that there is a way to disconnect your battery safely. My brother, a certified ASE, uses a rather older device that plugs into the lighter/12vdc socket to maintain a low voltage for short times while the battery is disconnected to replace the battery, work on air bag systems, etc. This device also will obviously maintain power to your GPS clock. Okay, those of you who know about this problem, please chip in to help those who may not know.
