DIC Messages
I was driving last week and the DIC started a stream of warning messages over and over until I returned home and turned the engine off. Started with "Service Vehicle Soon" then "Service Active Handling" Service Traction Control, Service ABS, Service Fuel System and finally Low Fuel. Took it to dealer next morning and the Tech cleared the error codes and told me to drive it and bring back if problem returned. Today after an hour of driving the exact same thing happened again. Vehicle is 4 month old GS with 2K miles.

I would also say the battery needs to be load tested before you do anything else. While it may not be the cause, those are common bad battery symptoms. I would guess you bought the car from the dealer lot which means the battery history is unknown. Typically, if they sit on the lot any amount of time, the battery may have run down and been recharged, sometimes multiple times. At any rate, its the easiest and cheapest thing to check and must be eliminated first.

Sorry, forgot to mention the battery and charging system was tested during first dealer visit. Vehicle was ordered and delivered a week after being built therefore it did not sit on the lot.

This is on a 2011 Vette? What a shame. I love my Vette, but GM's quality is crap!

The solenoid is the electrical center or distribution point of the car. Therefore the fuse boxes, alternator and battery all join there together. If that connection becomes lose, then you will have problems with lots of things.

The one thing I will add in this case is that the DIC also gave a "No Fob Detected" warning before I started the car. I had to slide the fob into the glove box slot to get the car started. Then when I turned the car off after the test drive, the doors wouldn't unlock or open. I had to use the manual release to get out. The car was definitely in the electrical twilight zone for some reason.
Keep me posted if you find out anything.

Wow...the B]same thing[/B] just happened to me last night on a test drive. The DIC went nuts and started throwing all the same messages you mentioned.

I'll still be very interested to hear about the OP's car.

Back to dealer yesterday morning and just received an update from the Service Manager. Bottom line is the car has not repeated the problem again however they have had a number of the modules disconnected so perhaps there was a loose connection that has is no longer. The GM TAC claims this problem has never been reported so they were no help. I'm going to pick the car up tomorrow and we'll see what happens. Thanks to all who have responded and wish me luck. BTW the Corvette Tech at this dealer has been with them 22 years and is an owner himself and I have faith in his work.

Hope it work out for you!
If I find out more details about the car I'm looking at, I'll post it here.

Interesting how they say this problem has never been reported, but I found at least 10 separate threads on this forum where the owner reports a continuous string of DIC warning messages that are obviously bogus...but not all were the result of weak batteries. Given that we represent a small number of Corvette owners, you'd think someone would have reported something similar by now.
Hope it work out for you! If I find out more details about the car I'm looking at, I'll post it here.

OK...in the case of the car I was looking at, the root cause of all the DIC messages turned out to be...(drum roll)....a clogged evaporator case drain. 
SAY WHAT!?!?!
Here's the full story. The drain tube from the evaporator case was pinched and wasn't allowing condensation to drain when the AC was being used. Almost a full gallon of water was sloshing around in the evaporator case (you could literally hear it sloshing around when making a turn).
This caused water to leak out of the evaporator and onto a BCM connector...which shorted the BCM in the process resulting in all the wacky DIC messages that made no sense. They dried out the connector, replaced the BCM, unclogged the evaporator drain line and now everything works just fine.
After hearing this, the owner did comment that he had never actually seen any water underneath the car whenever the AC was running.
So just when you think you've heard it all...

There's been lots of cases on the C-5's where the udders are plugged causing water to drip down onto and into the BCM, which in turn causes a nightmare in the car. Guess we need to start being concerned about the C-6's with this too.

While rare, a "new" battery can certainly be defective. Especially the riveted plate types that Delco uses
