Did you mean to say DELPHI module?

I've had some issues with Delphi aftermarket parts but not ACDelco.

Bummer. Hope it was just a defective ICM.
There are things you wouldn't even think of which will cause ICMs to keep failing.
One thing I wouldn't have suspected is excessive AC voltage leaving the alternator.
Worse still, the ICM isn't the only component that can get damaged by this.
Just something to check.
