I bought a used BMW X3 from a dealership and it had the manufacturer 100, 000 mile CPO. I took the car into Classic BMW after detecting a leak in the car. The leak was determined to be coming from the transmission cooler line. This line is an integral component of the transmission and it should be covered under the CPO but the dealer advised that it was not covered as it is "hose". The "line" is solid metal pipe about two foot long and is in no way a wear and tear item, an upkeep item or a "hose" as the definition of hose per Webster includes the fact that it bends. I contacted BMW of North America and they claimed this is an issue for the dealer..The dealer told me to complain to BMW North America as they determined it was a "Hose". I called BMW North America again and they said dealer made the call. There is no means to get this worked out as each BMW entity point fingers and meanwhile I'm out $1000 for parts labor and rental car. Don't buy BMW products thinking major components are covered under warranty as they find loopholes to not cover repairs under CPO warranty program.
