“The cylinder head has cracked and is leaking externally. The engine oil that is leaking out is leaking directly onto the hot exhaust manifold. This can place us as risk due to the engine oil getting ignited by the hot exhaust manifold. There were no warning lamps that came on but there was a smell of burning oil that all of a sudden came up through the vents. This vehicle is currently at Woodhouse Mazda in Bellevue, ”NHTSA complaint, 2019 Mazda CX-5 owner
“The engine has an oil leak from the head. It is a common problem with this year and make. It is a manufacturer's defect called a porous head where oil leaks through the casting not a seal. I've already spent $2000 to repair but still leaks. Oil leaks onto the exhaust and smokes causing fumes in the inside of the car and can be a fire hazard. Mazda is well aware of the problem but has yet to address it.”NHTSA complaint, 2019 Mazda CX-5 owner
“We began occasionally smelling an acrid smell, but didn't think much of it due to lack of visible leaks or warning lights. During a routine oil change at the mazda dealer, we asked about the smell, and the tech almost immediately found the issue, saying he had seen it a few times before. The oil is leaking from the head down onto the manifold due to what seems to be a recurring defective casting issue. quote from ma”NHTSA complaint, 2019 Mazda CX-5 owner
