Who or where did you buy this Crossfire? A dealer or a private owner? Since you bought this car in December 2023, was it acting like this when you test drove it? Do you have the maintenance history on this 27K miles car?
  1. How old is the battery? Did you check the output, if less than 12 volts, you need a new battery, since the electronics requires at least 14 volts to run the systems. Get a voltmeter and check the output of the battery.
  2. Who told you to change the RCM and a CPS? This type of scenario will empty your wallet quickly, unless you have unlimited funds.
  3. The alarm siren maybe draining your battery, since the internal batteries tend to fail on our cars, since yours is 19 years old.
When you open a thread, we need a little more info from you, to enable a correct diagnosis.

Good Luck
