Cracked cylinder head oil drips onto exhaust manifold smoke gets into cabin and could cause fire on exhaust manifold car was purchased used 5/22 and with 46732 miles and now has 74000 in 2/24 it is now at central Maine Chrysler jeep where we purchased it having repairs done under extend warrantee that we bought with the car.we spoke with the service department at a mazda dealer and they said it is very common i feel that mazda should recall it passengers should not have to breath oil fumes or risk being in a car fire we are lucky to have purchased the warrantee but without it the repairs would be to cost prohibitive for the average person thanks

Vehicle engine has stalled multiple times at low speeds. Vehicle will not restart immediately. In order to get vehicle to restart, gas must be revved while pressing start button to get engine to restart. It appears as if fuel is not being delivered to engine. Electrical components remain functional. Vehicle was inspected by dealer and issue could not be recreated. No issues were found. No warning lights displayed or codes found upon inspection. No symptoms of problem; occurrence is sporadic. It has caused traffic and safety hazards due to stalling in roadways.

-cylinder head cracked resulting in leaking and burning oil from rear of cylinder head by exhaust manifold. Car has since been repaired by Mazda, but pictures are available from the incident. -Car was unsafe to drive due to leaking oil all over road (Environmental risks and hazard to others), black smoke and burning smell circulated into cabin via AC (health risks to passengers). Prolonged driving in this condition would have resulted in loss of oil and further damage to the car and others. -Car was towed to independent service center then subsequently towed to Mazda dealership -Mazda dealership inspected and confirmed that it was a manufactured defect that they have seen with other cars. Mazda has a Technical Service Bulletin (TSB) issued as well. -No warning lamps appeared prior to observed smoke and leak, though it was noticed that the car did jerk slightly at times when stopped at a traffic light

Cylinder crack. Recently got a oil change and driving to work couple days after and smelled oil burning into my cab and smoke coming from underneath my hood. Got to work and opened my hood and noticed large amount of oil on belly and leaking oil from my cylinder. I got this vehicle thru a dealership and when contacted, they stated if I pay $7,500 I could get a trade in!!! After numerous searching, I've found a lot of owners with the 2018 Mazda CX-5 are having the same issue with cylinder heads and no corrective actions. Now I have to pay Mazda (after their defective parts) for their mistakes

This vehicle has stalled out while driving at least 4-5 times since purchasing it in 2018, although issues started about 2020 or 2021. It usually starts with the radio console either malfunctioning or going dead completely while I’m driving and several minutes later (usually after stopping at a red light but sometimes while actively driving) the car stalls out in the middle of traffic. It starts up after few minutes but it’s a very dangerous situation. It also sometimes hesitates when putting my foot on the gas, as if there’s a fuel injection problem. I already got all the recalls fixed but there’s obviously other significant problems with this vehicle. If it causes me to get injured I will be taking legal action.
