This is my first volvo, great car, but sometimes won't turnover. I have had the ignition switch replaced, that seemed to help for about 3 weeks. The battery has been checked and is fine. The dealer said he has not heard of any problems like this.....suggestions??

 

Welcome to the Forum. Have you posted this in the S40 section?

Your car should not be having issues like this already. It is a 2008 after all. So the dealer really has no idea what is going on? Did they check the computer for codes?
