Ford Fiesta biggest mistake EVER!

I'm a rep on the road, my car is my most valuable assets.<br> After extensive research I decided to go for the 1.4 Ford Fiesta,<br> I bought a '14 model from Avis in Jan 2015. It had 15 000km on the clock. I have done just over 23 000km to date.<br> On Tuesday the 21st of April my horror story began. I was in Johannesburg CBD doing my rounds when i saw that my heat gauge was abnormally high before stopping at my first client in Plein Street. I thought it might have been all the stopping and going in the CBD that might have caused it to over heat. I let the car cool whilst seeing my client. On my way to the 2nd client i was forced to stop in Selby when the temp. warning light came on. I had to stop the car various times in a very dangerous areas. I feared for my life! The oil and coolant levels were perfect and couldn't see any leaks. Called the AA and a hour later I was towed to Eagle Corner, Thursday i was informed that a Plastic Bag had burnt out my cooling fan ***! Thus over heating. If something small like this can cause a \Ford"to fail. This will be my last ford as It can cost you your life. The air-con needs to be re-re-gassed and no leaks were found? ITS a CLOSED System!?! Ford=FAIL :("""
