2008 gtx 155 is not starting perfectly. About 1 of 5 times I get a click, click sound. I can continue to fiddle w the button by pushing it several times and it will start nicely. The battery was dealer installed about 7 months ago and the connections seem secure. The symptom strikes me as a starter or push button problem vs battery but wondered if you all have seen similar instances and know the cause. Not overly concerning bc it doesn't take a lot to get it going but nonetheless, would like to disagnose and monitor in case it worsens.
