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.
Try to start the car, run it for like 5 secs, then turn it off right away. See if the car can re-start right away. If it does then wait 5 secs then turn it off again. If it's the battery problem I don't think it will be able to do 3 quick starts. Only a healthy battery can do that.
Have you noticed if you car cranks at a slower pace than normal ? Do you live in a cold area ? If you live in a warm area, battery problems take more time to detect.
Unless you have a dead spot somewhere in your starter solenoid but with such low mileage I doubt it.
I just had my starter Solenoid replaced under warranty, but I am having the same issue. I think its just the battery not holding a charge. I'm gonna get my Altinator check just in case, but I have just been too lazy to go get a new battery.
Keep an eye on the voltage reading on your radio display when it's running mine says 14.6v. That should be as good as getting the alternator tested. If you replace the battery, look for one that is around 800 CCA or better. No need in spending $150 at the Dealer.
I noticed yesterday while i was looking under the hood that this was not the original battery. This wasnt even close. It was like half the size of the battery tray and was only 525 CCA. That has to be why it was having trouble starting randomly.
I am going to look around today and see what i can find to replace this one.
