Does Any One Know Why The Passenger Side Battery Leaks Out The Vent?? The 3 Rd Battery Since 05 Is Now Leaking -- Dealer Say Theres Nothing Wrong With System And That Gm Wont Pay Them To Replace Battery Again! The Service Manager Suggest That I Replace Battery With One That The Vents Are Located Else Where.. The Truck Is Still Under Warranty. Any Input Would Be Greatly Appreciated . Thanks

3rd, take a look at this thread... I've had the same problem. My opinion is that the AC Delco batteries are junkola.

My passerger side firewall batt is doing the same thing. but I am to hardheaded to bring it in. My truck is still starting good when it starts giving me problems I will take the time and fight with the stealer.
