NHTSA Complaint #11583891 — 2014 MAZDA MAZDA3

While accelerating onto a highway, my engine overheating light flashed then stayed on and my acceleration suddenly throttled back and my car started slowing down. I was able to pull over on the shoulder, but there was a close call with a semi bearing down. I had my car towed to a repair shop, where they told me the water jacket had cracked and the overheating caused a blown head gasket. This was repaired and tested. A week later, I got the car up to highway speeds and the engine overheating light flashed again. When I stopped and looked at the engine, there was foamy tan coolant all over the place. Towed it back again and was told the weld had failed. But in trying to find a used cylinder to replace mine, the shop told me that all of their sources said they had no used ones available because the same crack happened on those as well.
