Business ProfileforCoeur d'Alene Honda

I purchased a brand new car from this dealership in June of 2017. I specifically purchased from this dealership due to the lifetime powertrain warranty they offer. At their recommendation, I keep record of every service the car has ever had. In september 2022 I had my car looked at by this dealership due to seepage from the transmission, which they noted but said it wasn't a problem and to keep an eye on it. It is now May 2023 and I have taken the car in again to a different honda dealership and they determined the gasket on my transmission pan has failed, which is not an inexpensive fix. I contacted the warranty company who stated they will not cover this because replacement of gaskets in the transmission is not covered in the warranty. This is confusing to me because I assumed that all parts of the powertrain would be covered under their "lifetime powertrain warranty."I contacted Coeur D'Alene Honda to express my frustration with their lifetime powertrain warranty not actually covering the full powertrain. I spoke with **** in the service department who confirmed to me that the gasket on the transmission pan going out is not typical for a car with less than ****** miles on it. Whose responsibility is it that this gasket went out? I spoke with them at length and stated I understood that the gasket was not covered under warranty, but I don't understand how they can advertise lifetime powertrain warranty but not actually cover all parts of the powertrain.
