Column Lock Module Replaced - Now Low Voltage Issues
I recently had my column lock module replaced due to the infamous column lock fuel cutoff issue....now I am getting a low voltage error and the car delays on start up. Any ideas?

The fact that you are seeing low voltage issues (with the engine off, right?) confirms a battery problem. The cure is to replace the battery.

Paul Koerner, GM World Class technician and Corvette specialist, says that the #1 cause of the column lock issues is low battery voltage. He's kept records on hundreds of column lock problems that he's worked on, and says over 80% of the time the root cause was a weak battery. The column lock sensor looks for under-voltage.

I would see if you can have them remove it and refund your money (assuming you're talking about the lock mechanism itself). The locking mechanism will fail and you will want to buy an LCM5. No matter what the dealer says the column lock issue was never fixed, even with the various recalls. If you do a search on here for LCM5 you can see all the in-depth discussions about it.
I know this isn't helpful to solving your issue but if you can get your money back and spend a fraction of it on the LCM5 which is a permanent fix then I'd go that route.

Or first make sure the battery is fully charged and have it tested to make sure it wasn't bad. It could just be low or have a parasitic drain and just needs a full charge. It would be a shame for someone to spend the money on a brand new battery when all they needed to do was charge their perfectly good one.
If battery tests good, but low voltage problems persist, then two possibilities include excess parasitic drain, or weak/inoperative charging system.
