Took my 2012 500 Sport in for its first oil change yesterday. Service guy called me back to the work area to show me something. Car was up on the lift and he pointed out engine oil at the rear of the engine. Got a call this evening with the diagnosis---rear seal needs replacing. Car is 5 months old and has 6500 miles on it. Should be ready to go Monday or Tuesday. Hopefully this will be the only issue I have with this car. Its been running and driving perfectly so far. Really love it and plan on keeping it for many years.
