My vehicle has 64k miles and has had regular maintenance — oil changes, etc. it has recently developed an oil leak. I took it to the dealer today & they said the cylinder head and gasket needs to be replaced. My car has not overheating or even run warm. I understand there are 2019 CX-5S that have had a casting issue with cylinder heads. I feel sure thatas what the issue is here yet they want almost $6k to repair my vehicle!
