Battery Dead problems of the 2009 Buick Enclave

Two month old battery went dead. Discovered water surrounding the battery and soaked all under carpeting on floor boards. Warranty is expired and since I am a widow on fixed income can not take it to Buick as they charge exorbitant prices for problems that should be covered and not happen. Aaa driver said there appears to be a seal someplace near battery that has come off letting water come up through the underside and collect around battery .

Issue: battery not holding charge and frequently needs jump resolution: dealership verified and found that battery had bad cell. Battery replaced issue #4.

Purchased new 2009 Buick Enclave cxl fwd(3/30/09) fully loaded. 4 months later, battery died. Made 5 or more visits to gm dealership. They ran parasitic drain diagnostics over night , new upgrades installed, replaced battery twice and more than a year later, every couple of months battery dies. I think there are many people out there with this kind of problem that gm should fix the problem under a recall before some electrical catches on fire and gm will have to payout millions.
