I have an 03 yukon and the battery keeps dying. I have replaced the battery and the alternator is putting out 12-14 amps and the diode test for the aalternator reads good. No lights seem to be on but every morning the battery is still discharged. Are there any known issues with the electrical system in these trucks

there are these couple of bulletins on it. I also read somewhere the BCM or PCM may need to be reflashed.

Thanks....... I brought it to the dealer and they first told me that the new battery was defective so I had it replaced. The put a drawe test on it and after the car was off it is still drawing 4 amps. I checked Gm TSB and they are aware of a "Parasitic draw" on these trucks now comes the fun and expense of them finding and fixing the problem
