Why does Dodge go cheap with their steel?

Got a company 2013 Dodge minivan. It now has 52,000 miles on it and it has 2 HUGE rust bubbles on the leading edge of the hood on either side of the raised section. I am not too worried about it as it is still company vehicle and I am getting a new one in about 5 months but it is unbelievable, 4 years and 52,000 miles it's rusted.
