2007 Saturn ION irratic shifting, speedo, tach, door locks, PWR STR

2007 Saturn ION. Many things happening and problems are intermitant. Starts and idles fine. Power locks start clicking randomly. Speedometer and tach both move irratically. PWR STR showing, but electric steering is working. When driving, it shifts hard and up and down shifts irratically at every speed. I only have disconnected battery, let sit all day and reconnected. Same issues.

I hope you get some great feedback from the community here! If I can help by looking up open recall or warranty information on your vehicle, please send me the last 8 of your VIN via private message.
