Odd!
Nothing about what you were told would have been my first guess/suspect.
The coolant temperature sensor would have been my first test.
Clearly it's telling he ECU the engine is cold so it starts,
but it's signal is supposed to vary as the engine gets hotter,
and it sounds like yours is still giving a signal it's cold.
What used to be "the choke is stuck on!"
From memory a new CTS is around £!0-15.
