Yeah, we haven't finished endurance for the last 3 years. It's always a design failure. Two of those three years the car drove only four hours before the actual competition. The result is a car that dies in the "infant mortality" mode thus pointing to an obvious design failure.
FSAE cars are light and the engine runs restricted so all the components you can buy are overkill for our applications.Barring any misuse of OEM parts, it's the parts you design that will fail.
