I’ve had my car 2007 Solstice for 4 years now. This battery issue has been going on the whole time. I’ve taken it to the dealership 3 times and they say they’ve tested the entire electrical system and find nothing draining my battery. I’ve replaced the battery numerous times and the dealership has just replaced it. Still having the same issue. Try to start my car it will start, next day, try to start it and nothing! I’m pulling my hair out! The transmission modulator valve was replaced prior to me purchasing this car. Please help!
