BAD / VERY DISAPPOINTED

I bought a Car 2 Months ago from Nissan. Toyota Urban Cruiser XT , Yesterday Morning the Car struggled to Start , I didn't drive it the whole day , Last Night when I drove it still struggled to start and the engine light came on as well as the engine is boiling hot , It is a AT and it didn't even change gears while driving , I left my car at the place I was to phone Toyota this morning to find out what I should do , Toyota assisted me and took the whole day with the Car to find out what the problem is and I thank Toyota for helping me , but I need a car as they won't be able to give my car back to me today , Nissan is refusing to assist me , I phoned the head office and I phoned the management!!!! I am disappointed in NISSAN for selling a car to me and in 2 months time this is now a problem as well as they can't make a plan to assist with a Vechile until the problem is sorted out !! Head Office Nissan is telling me Toyota needs to give me a Vechile and not them !! I feel I bought the Car from Nissan it is not even 2 months old and on warranty and this is how they are treating me ??? NISSAN you will never see me buying a car from you again!!
