About once a week, we'll go to start it and will get a click, then nothing. All electrical stuff comes on when the key is in the on position though every time. No replacement parts have ever been required on this 2 and 1/2 year old vehicle. First time we jumped it and that worked, second time we just waited a little bit and tried to start and it did. We are on third try now, kinda tired of it. My wife thinks it's only after rain. Got any advise?
