vehicle high pressure fuel pump is attached to and a part of the left camshaft in the engine. Although a major and critical component of the engine and propulsion, the fuel pump seized, exploded and shredded itself and the camshaft at the connected point sending shards of metal chunks and pieces into the engine causing catastrophic engine failure. The engine immediately went into limp mode on the highway at no less than 70 miles per hour while passing an 18 wheeler which, was a major safety issue and could have caused a crash causing serious bodily injury or death as a result. According to my research, this is a known problem. Porsche was contacted and ignored the complaint. The engine had to be completely replaced.
