Why Do Mazdas Experience More Engine Blowouts?
2 Answers
This is an extremely rare occurrence. The engine bolts broke inside the cylinder block without any external force, which definitely does not indicate a quality issue. It might be caused by the driver applying excessive force when braking, or the use of counterfeit engine oil that softened and deteriorated the bolts, leading to the fracture.

Speaking of Mazda's engine knocking issues, I've driven many cars and studied design details. Mazda's SKYACTIV engine emphasizes high efficiency, using high compression ratio design to enhance power and fuel economy, which is originally a good thing. However, it becomes a burden in real-world usage. If the fuel quality is poor, such as using low-octane gasoline, it's prone to abnormal combustion during operation, leading to engine knocking. Additionally, the turbocharging system in some models increases the load, making this issue more likely to occur under high-speed or high-temperature conditions. Owners report that this knocking phenomenon mainly occurs during aggressive driving or continuous uphill climbs, which is quite annoying. To avoid it, good habits must be developed: first, insist on using high-grade fuel; second, regularly check spark plugs and the cooling system to ensure the engine doesn't overheat. I've personally encountered similar close calls, but after adjusting my approach, I've had no further issues.
