2005 Corvette Electrical Issues
Hello,
I bought my 2005 Corvette two years ago. Car had 87k miles on it. I've had some minor electrical issues. Sometimes display says my front right tire is flat, or it doesn't remember my memory seat programming. Just minor stuff that I can live with. However last week I went to start car and there was about 1/4 of a crank and then nothing. Panel and radio was just on. Was pressing button to turn it off and everything was frozen. Disconnected negative on the battery for a few minutes and reconnected and now nothing would turn on. Only headlights and trunk(from remote) would open. AAA said that there could be a faulty ground wire. Searched around and looks like that would be hard to locate. Was wondering if anyone else had these electrical issues.

And the most common issue when this happens is a bad battery. Mine recently died and I had all kinds of wacky problems when it was low. Idiot lights, only passenger side headlight on, ignition wouldn't turn off. New battery and good as new. Your tpms battery getting weak is likely the cause for not reading tire pressure. They are supposed to average about a 10 year life.

How old's the battery?
In hot climates batteries really don't last as long as many assume, especially w/ C6.
When these new fangled batteries go they go, one moment car starts next it doesn't.
Only real clue is when/if mysterious electronic issues pop-up w/ an ordinarily reliable car.
Have battery load tested regardless if relatively 'new', could have a defective cell/internal failure.
Also, checked for codes?
If no reader most all parts stores will read codes for free, providing it can get to store
They'll 'load-test' the battery w/ a quality load tester free, too.

My 05, gives me all kinds of faulty problems when it need a new battery, I have learned after years of owning it.
I would say for your TPMS problem, you might say they need replacing after all, replaced when I had new tires installed couple years back getting low pressure reading, but when it goes to XXX, the battery are dead.
Someone else asked how old is your battery??????
