Default 2005 C6 False TPS Warning

I just purchased a very clean 2005 Roadster Base Model with 49,000 miles. Love the car, but it has an electrical issue:

1) Occasionally thinks it has a flat tire for 2 minutes before recognizing it doesn’t.
2) Cruise Control never works on the first start each day, but does on the subsequent starts of the day.
3) Traction Control never gives a DIC message, but also doesn’t control traction (wheel spin is more fun when it happens on purpose.)

I’ve read a bit about the need for a battery tender and I am wondering if a new battery wouldn’t solve these issues or if this cluster of problems is indicative of something else being wrong.

Thanks in advance for any counsel you can offer.

For one TPMS on tires may need to be changed.

I have a 05, and tell you when you get false warning in my car I replace the battery and everything disappeared.

If your getting TPMS false reading, does it read 0 PSI or XXXX, it could be your sensors needs replacing, I replaced all 4 at the same time when I started getting XXX reading. Those battery in them don't last forever.
