It might be a week or a month or 3 months. Sometimes my car wont start. Example - I have been driving around and i am getting ready to stop and get some gas. When i get back in the car to start it sometimes it just wont turn over. If i get it jumped it does and its fine.
This also happens if i keep the car in AUX and listen to radio for more than 2 mins. Is it just the battery? Or is the alternator a problem?
Once the car starts the battery levels read fine. This doesnt happen at any normal time. It is completely random and happens at different times, temps, places, everything. Also if it happens today i can drive it around and it might not happen again for awhile or it might happen the next time i try to start it.
This is a 2003 Cadillac CTS with 37,000 miles on it.
