So I go out to start my fiancee's car and it does not start. I tried a second time and it didnt start. I check the information center on the dashboard and it reads that my battery voltage is at 8.4V. I'm sure it should be higher; from general knowledge of vehicles. I went to check to see if anyone else has had a similar issue with same models online and I found that it was more common than i suspected. I need help sorting this out.
