Dug out my warranty info, Rvn you are spot on. I couldn't find the leak coming from the radiator or hoses so I took it to the dealer hoping it was a warranty issue. Took them two days and they finally found it...a seal in front of the flywheel, said they have yet to see it. They'll have to pull the tranny and flywheel to get at it. I'm definitely not happy but glad it's still under warranty. My '02 never had any issues other than the the injectors. So far (on my '15), I've had my oil pan leak, def heater fail, and now this.
Anyone else have a similar seal failure?
