I have a very small and sporadic coolant leak that drips directly on the gas pedal. It only happens after the car is parked or drove up a steep hill. I do not lose enough coolant to drop the level on the reservoir. It has been to the dealership twice in the past, (June 2008) 1st trip they replaced the heater hoses and gaskets, (Oct 2009)2nd trip new heater core and gaskets. I am going to contact the dealership Thursday and see if they will stand behind their work and make it right. What do you think could be leaking and do you think they will warranty the repair since they have never corrected the original problem?
