Have a automatic sahara with 52,000 miles. My car will not always start. I turn the key and nothing happens. If I go for gas there have been times when the car would not start. It will take me at least 30 minutes with several tries and it starts. The car is out of warranty now. I have had the starter replaced, new battery, key modules, battery casement wiring replaced. Chrysler has absolutely no clue what is wrong with the car and is giving me a hard time because they get the car when it is running. Need help!!!
