Carrier/rack problems of the 2014 Ford Fiesta

Have had constant issues with the radio unit, now on my 2nd unit. Radio starts making a popping, crackling, thumping loud sound from the speakers, until stops working with no sound. Then these thumping sounds are generated even with the radio off (not playing anything)! which I presume a short or wiring issue. I'm shocked we haven't gotten in an accident from jumping/jerking the steering wheel when it happens. Many complaints online to Ford about Fiestas and focus vehicles but they have not done anything, and the dealer just wants to charge for labor just for inspecting. Please look into this issue. Thanks.

Car overheated, blew hose, and cracked cylinder with new fan and fluid. Car does not shift correctly and will speed forward.

The car would make a crackaling sound through the speakers for months starting in March of 2018 and on July 5, 2018 the radio , & blue tooth options have now ceased to work.

While driving, speakers start to crackle loudly. Its actually startling. Then the radio doesn't work until the vehicle is turned off and then on again.

Snow is entering through the cowl top are and melting, the water enters the blower motor and then freezes the blower motor. This makes it so my car has no heat or functional defroster. When I brought the car back to the dealership I purchased it from they stated it was a "design flaw" and "common problem. " the suggestion they gave me was to keep snow and ice away from the cowl top which is unrealistic for where I live. I have driven to and from work three times this winter without heat in my car, and since there is no defroster my windows also have to be cracked open to make sure that windows do not fog.

The hinge on back driver side cracked first ,,,got fixed ,,now back passenger side cracked and they wont fix . . Warranty expired. Also my front passenger door don't latch closed must tie shut.
