Ok - last year this car blew a head gasket - luckily under warranty - NOW one year later the engine has blown - took car to dealer and luckily still covered under warranty - HOWEVER we must show receipts that the car was regularly maintained since it wasn't done at the dealer - the problem here? Well my son in law is a certified mechanic (for 20 years) and of course he is the one that has done all the maintenance on this car - saved us alot of money over the years but of course no receipts - a blown engine at 50,000 miles - are you kidding me? Not sure how this is going to pan out but this car is a piece of crap - will never buy another Nissan - I will stick with Fords!!!!!!!
