Battery has 13.7 volts
That's smoking good voltage from a battery installed in a CTS with the ignition on and engine off, like a battery with no load at all on it. Check battery cable connections and don't trust that reading without a formal test. I didn't know a reading that high connected up was even possible from a typical car battery. I'm in agreement with the previous response as your symptom is characteristic of a bad battery, good enough to power up the dash, but no guts to start. Check your oil level also, a seized motor and or bad starter tends cause this kind of symptom, but then neither of those situations would leave a battery with a 13.7 v reading after the first start attempt.
Its because it has been hooked up to a trickle charger for about a week. I got the same reading using a multimeter on the contacts under the hood. I think this is definitely an issue with the battery connection, but I don’t think it’s the battery itself. Tried cleaning the battery connectors in the trunk and same results.
I just watched the video for the first time. The engine light flickering is concerning for a bigger problem than a battery connection issue, unless it's the result of the video. The engine light will flash under certain circumstances when there is a problem, but the only time I've ever seen an engine light flicker like that was when there was a problem with the engine computer. I noticed stabilitrack is off also at power on, I am under the impression that once the car is turned off it defaults to on until it is turned off again. I believe at this point the car needs to be scanned for computer codes.

I think this is definitely the cause. Any solutions?2008 CTS-won't start seems dead but weird stuff...
Have a 2008 CTS. Car was running great. Got OnStar report saying all is well. All of sudden I couldn't get the car to start. Lots of flashing lights when trying to start. But no go... Then when I got out doors all locked and I had to use the key to get in. Clock still keeping time. Earliest...
Water infiltration via clogged sunroof drains can be a contributing factor as well.
I swapped batteries with another one I know is in good shape, fully charged, and tried using portable jump starter too. Battery is measuring 13.7v.
It is a flicker. Not just the video. I will scan for codes and provide them.
That should prove very helpful as this is not to be confused with blinking and flashing, those terms are the same here, but flickering is uncommon. You may even have trouble linking up with a scan tool as a result.
Any luck on codes my car is doing same thing
Did you pull your codes? I don't think Crad will be back.
