In that case I wouldn't be too concerned . Being a recent purchase and if you haven't had a TF or F before , do please keep a check on the coolant level . The 'N' series engine has the more resilient gasket but the cooling system is quite complex and has hoses that if not checked fail just like any vehicle. Your LE will have the low coolant level warning system to give advanced warning of coolant loss so you have some comfort in that. 
Enjoy your purchase . I'm still loving mine.
