Ive had this car for 2 years and for the most part of the second year ive spent a considerable amount of time jumping my car. I replaced the alternator, and bought a new battery. 3 weeks into feeling good about the solved problem my new battery is drained out again.
please help.

I recommend measuring the key off current draw with all the doors shut and the car in "sleep" mode. The general module may be suspect if the car will not go to sleep. Sleep is achieved with the car off and all the lids shut, wait 16 minutes and see if the shifter indicator light goes out and stays out. If not then it may well be the general module.
