has anybody with the 3.7 engine had any starting issues...the jeep only has 44k miles on it and every so often we go to start it and get one click like the starter took a crap.try starting it again and it starts up no problem.i checked identifix at work and got no helpful info.it has a brand new mopar battery so i know its not that. before i throw a starter in it, just want to check feedback from you guys, maybe its a freak bad ground or something let me no what you guys think.
