Here's another

And another

These all came from a google search for 'c41 error' and 'c41 corvette'.
Could be a PCM module, a bad wire somewhere in the data communication wiring. Doesn't look like an easy find or fix.
bad grounds. On the C5 there are 13 different ground locations with multiple connection
points at each, I'm sure it's the same on C4's. Any bad ground will give bad voltage message
to any system and that will produce a code for that system. Good luck.
Thank You

Thanks for getting back to me!! :sick:
Still, I am suspicious of all the build up you found on the battery and cable terminals and the fuses(?) too. Cleaning the ends that are visible is no indication that corrosion/damage didn't travel up the cables. A change in cable resistance (due to corrosion) could easily explain your troubles.
I'm not a mechanic - just my opinion.
:confuse: :sick:
And according to my dealer, wait until you try and check or change spark plugs!
I'll give updates when i can.

It has nothing to do with starting the car.
any ideas what the problem is?
2) You may need a new battery.
I'm very sorry to hear that you're experiencing these electrical issues with your new Corvette. Are you planning on working with a dealership to get this looked into? If we can look into anything on our end (open recalls, for example), please get in touch via email at socialmedia@gm.com
All the best,

There is a significant design flaw in these vehicles and I'm sure Corvette Division knows about it. I don't even think it's all that rare. But make no mistake, these are death cars. Any car that will electronically cut off power while driving and lock you in your own car is a car you don't want too own.
God help you if there was a fire and that safety latch fails like mine did. Toast. (if it happened to me again, I'd release the roof and knock it out, probably destroying the roof panel but at least escaping. Still you wouldn't want to do this at night in the fast lane on Interstate 5, would you??) Doors that require an electrically driven solenoid to open are just plain stupid and should never be used. They're not cool, or cute, just stupid.
Don't buy these cars.
I personally wouldnt touch an 8 year-old car with only 11,000 miles on it. Cars need to be driven, otherwise youre just asking for problems.
Actually all had nothing wrong with them. I know these guys have families and house payments etc but it's a shame they don't work some place like dsw shoes where they can do no harm.
No, the corvette elect system is a special kind of lunacy that one has to see up close to fully appreciate. there have been over 250 sbs on this model and half were related to the electrical system.
The sad thing is that the car doesn't need any of this crap. The engine, transmission and suspension are enough. The quality of most of the other components is exceptional. But the elec system is something that should never have been allowed on the car. Turning a car into a 'system' is risky at best and the gm people have not been up to the challenge.
Your comment tells me you have never heard of the 'Serivce trac system - Reduced Power Mode' phenomenon on these cars.
I'm sorry that this happened to you in your Corvette and we want you to feel that you have a safe and reliable vehicle. Have you made a case with GM Customer Service already about this? If not, we would like to start one for you within our system. If this interests you, please email us your full name, VIN, contact info, mileage, dealership, and a few details of your experience to socialmedia@gm.com.
Thank you

Agreed. Edmunds is a great place to chat about cars, but for deeper, more specific information/discussion, the specialty enthusiast forums are where you need to be.
PS: No, I haven't heard of the specific failure you mentioned. These systems are very (and unecessarily) complex and interconnected, so Im not surprised the dealer is struggling to figure it out. I had a Buick that had all kinds of electrical gremlins that could never be repaired. I lemon-lawed the car and GM bought it back.
Good luck!
