I have owned 2 Cruzes. The last 2 days I have smelled rotten eggs. I checked and the battery seems to be overcharging and spilling bad stuff! I admitt I am a woman and know very little about cars. I have a 2014 Cruze that I bought 3 years ago used from a dealership. Obviously I need a new battery, but why is the old one boiling? Will the car destroy a new battery? Please advise. I have had terrible headaches for the last 2 weeks....
