First, the battery dies if the radio is turned on for more than 10 minutes with the engine off. The car needed a jump-start. This happened three different times. Second, there is a delay when trying to start the car. The dealer replaced the battery stating "the battery was defective. " less than a year later, same thing starts again. So I take it to the dealer for an inspection again. Ironically, this time the battery actually died at the dealership. After a few hours, the dealer states that the battery is "defective" again!! and now they're trying to make me pay for the old defective battery that they replaced. My 2007 Yukon denali xl was purchased brand new and went through three new batteries. The vehicle only has 30,000 miles on it. What will happen if my wife and three kids are stranded again??? this is not a battery problem. It is an electrical problem gm is trying desperately to cover up. Please help. Getting very aggravated and frustrated with this issue. It may not seem like a life-threatening issue but this problem does have the potential to become one.
