2019 Mazda CX-5

My engine started smoking while I was driving fast got out of car oil leaking everywhere there was a crack in the cylinder head, another few minutes of driving and the car could have burst into flames seems like it’s a common issue with Mazda cx5 a quick google search has shown me I’m not the only one with this issue, worst thing about it is Mazda refused to fix it.

My engine suddenly started smelling like burning oil. I was due for an oil change and needed it immediately so I went to a quick oil change shop. They told me oil was sprayed all over the engine and I should take it to the dealer. It's been at Napleton Auto Park in Urbana, Illinois for a week and they finally diagnosed a cracked cylinder head. They said it could take up to 2 months to repair and they're checking to see if it's covered by my warranty.

My 2019 Mazda CX-5 cylinder head cracked at only 60,000 miles. I noticed my breaks were smoking and stopped driving. I then noticed oil leaking from my engine which had blown into my breaks, causing the smoke. There was no check engine indicator on my dashboard, nor did it indicate that my engine had overheated. There was no indication that there was any issues with the vehicle until i noticed the smoke coming from my brakes. I towed the vehicle to the Captial Mazda Dealership in San Jose, CA. Per Mazda Dealership Repair Estimate: "cylinder head cracked by cylinders 2 and 3". When i asked the dealership service center why this happened, their only response was it was a engine failure and that "over time the cylinder can become warped and crack" and while it that doesn't happen often "it can happen" I asked if there was anything I did that caused this, their only response was "i can check with the technician again". Apparently I did not purchase the "extended warranty" so while the repairs are no fault of my own, I have to pay the $6,000 repair cost.

Noticed the smell of burning oil in the cab on 30 mile drive. No warning lamps or other symptoms; vehicle continued to operate normally. After parking and inspecting the engine for the burning smell, noticed oil dripping from underneath engine bay and a pool of motor oil was forming on the ground underneath the vehicle. The next day, vehicle was brought to local Mazda dealer for inspection. They diagnosed the cause and stated the engine needs a cylinder head replacement. Oil leakage was so prolific, if this were to occur during a long distance drive, the engine would have lost all of the oil and stranded motorist - safety concern. Cylinder head failure is a known issue (Mazda TSB [XXX] ) with this engine. This known safety issue should trigger a recall. At minimum, the repair should covered by manufacturer for life of vehicle.
