NHTSA Complaint #11499946 — 2011 FORD FIESTA

My 2011 Ford Fiesta shudders, has sudden or Delayed Acceleration,delays in downshift, difficulty stopping/braking,it hesitates when changing gears.also has harsh engagement.I purchased from a private owner in 2021. I have contacted Ford Motor Company Headquarters. I have taken it to my local Ford Dealership,told them what it does, they would not drive it so they could see what it does and how dangerous it can be at times. All they said was "oh it's the TCM and we got them back ordered for 6 mths" But if I want to pay for and order the part and just leave my car setting at the Ford Dealership until the part comes in I can do that. Then pay God only knows how much for them to put the part on. This is the only vehicle I have right now. I told them that. They said "oh we can't give ya no loaner car for that long. And the longer you drive it like that the more it's gonna tear up other parts of your car. And The Ford Motor Company said Oh you missed the deadline for the buy back program or any compensation for your carI Ford has failed to meet the standards required by The Federal Motor Safety Commission and yhey refuse to acknowledge me or help me in any way. All the other 2011 Ford Fiesta cars with the Dual Shift Clutch Transmission were fixed or bought back or the owners were compensated. I am in the same unsafe predicament as those consumers were. I'm not asking for a brand new vehicle Or thousands of dollars. I just want my car fixed and something to drive to work and to the grocery store while they fix it. Or another car of equal value to what my car is supposed to be. Thank you in advance for anything you can help me with.
