I can tell you this, there have been others as well. Your just going to have to take my word on it. As far worrying about it, I am not. There is to many variables to how or why they happen, ranging from the driver to inconsistencies in manufacturing. In the grand scheme of things engine failures in these cars are very few at best. Which is great! But all manufactures have them, hell Porsche recalled every 911 GT3 for engine failures.
