2018 Mazda CX-5 UNKNOWN OR OTHER,ENGINE

The cylinder head cracked and broke resulting in a massive oil leak that covered all the parts under my car and under the hood and engine which in result started to smoke. This is not only a major issue of extremely costly repairs but more importantly also serves as a major safety issue. This could had caused fire to the vehicle and also engine misfire resulting in engine failure while in drive and potentially lead to critical injury or death for me and my family. Mazda was aware of their poorly designed engineering for this critical and extremely important component and it is known Mazda recognized the issue by issuing a TSB. After further research there are numerous TSB issued for multiple engine failures with Mazda. It is also known that certain VIN number vehicles manufactured with this defect are commonly reported and have experienced this exact same issue within only a few years and or very low mileage. This is a major mechanical failure to happen to vehicles within a short time span of purchase and results in loss of customer trust and loyalty. As a first time car buyer I am deeply dissatisfied and disappointed with Mazda. I would not had purchased a brand new car if I would had known I would experience this only at 5 years and 71 thousand miles. My vehicle was inspected and diagnosed by a certified Mazda dealership. I was advised and informed that this is a huge issue that has happened with all customers. Mazda knowingly neglected the proper manufacturing and engineering for the cylinder head and other engine parts, which is the most critical component to any vehicle to function and operate. Lastly what is more concerning was that there was no warning signs such as lights or sensors that were triggered as warning of the issue and vehicle failure posing as another safety concern for drivers.
