The engine developed a sudden coolant leak on the rear of the engine. A warning comes up stating that the car could overheat and lose power. After a few minutes and no sign of the car overheating, the car loses power and slows down on its own. The car has not yet been seen by the dealer or a repair shop due to no appointments available. Mazda USA has issued a TSB stating the issue with the engine and they state that a design flaw causes the cylinder head to crack because of the external forces from the exhaust system over bumps. The failure appeared all of a sudden with no warning lights or indications, it just started leaking a small amount of coolant one day. Now I'm waiting for Mazda USA to tell us how they are going to remedy this issue and provide assistance. According to their TSB this affects three different vehicle models with the same 2.5L turbo engine built from 2016 to 2020.
