Engine Clicking And Tapping Noises problems of the 2013 Ford Fiesta

Purchased this vehicle as a certified used directly from Ford dealership. Since the second day of owning it, on acceleration there is a buzzing noise under the hood (sounds like a go-cart) and feels like it is clogged. Will accelerate suddenly or will have trouble accelerating especially when getting onto highway which have put me in a few dangerous situations. When coming to a stop or accelerating from a stop you can hear lots of metal clanking and sounds like its chugging. The vehicle vibrates, skips, like it is trying to get in gear on acceleration. Having trouble finding a Ford house that has time or willingness to repair. Any I have called have said it would be 3-4 days before it can get looked at and won't issue a loaner in the meanwhile. I can't go 3-4 days without a car. Monday morning, I am taking in to a dealership and leaving for them to access. This car was purchased for my teenage child who will be getting her license soon, after driving this car for 2 months I do not feel it is safe for her to drive and will be looking at other options for a vehicle.

I purchased my 2013 Ford Fiesta from a dealership in may of 2013, in October of 2013, my not even 6 month old car, started to make grinding and crunching noises in the engine and the transmission was slipping. I called the dealership and took it in. They replaced the transmission and after 8 weeks, I picked it up. The noises were gone, but quickly came back a couple months later, I kept getting told it was normal, but it has gotten worse. I am trying to work with my dealership now to quickly get this resolved. I am also only getting 25 mpg.

Within 1 month of driving I kept hearing crazy grinding noises and it would bog out between 0-30. . -rpm would jump to 5 on slight acceleration than dive back to 0; Ford dealer did "computer update on electronics" - did not fix problem; they said I needed to "adapt to the different clutch"; car continued to have problems between shifting into 2nd gear- took to dealer and another "update" was done. I was driving on major highway and had to drop speed from 45 to 30 to crossover to different highway and the car completely locked up as if it went into neutral. I managed to get car home without having a stroke and shut it off. When I got home I called dealer who came and towed it- the dealer replaced the clutch. After about 2 mos I noticed it was not shifting right again and became concerned for my safety due to prior highway incident. I took it in and the transmission was completely replaced; along with another clutch. Now it is making a ticking sound and I am concerned of a gas odor. I will be taking it back again. I filed lemon law on it after the highway incident. My greatest fear is that this car is very popular for middle class families looking for an affordable car for their new teen driver. The new driver will not be experienced enough to realize how to handle the situation or know that the car is malfunctioning. The 2013 Ford Fiesta needs to be recalled!!!.
