NHTSA Complaint #11541198 — 2017 FORD EXPEDITION

I've received several letters about Motor Vehicle safety since last year. I contacted the Ford dealership last year for it, and instead of fixing my car, they hit it while waiting in the dealer, so they focus more on fixing the hood that was damage and body of the car, and pressured me to sign a document to agree to fix it, while I had my husband at the hospital in ICU. But, the recall problem was never fixed, they said because they didn't have the part. Something in the engine was damage, so i had to take the car almost every month to try to fix it. I kept getting letters about the recall, and they kept saying that the part was ordered and they were going to call me when ready. Never did. Last week around August 25 i received another recall letter. I added in my to DOs to call, as a single mom now, its a little difficult, so i could not call during the week, and Sunday 8/26 while I was driving my car with my children, we could hear a weird noise, then smell of smoke, and some smoke coming from the front AC blower, then the AC stopped working. I contacted the dealership this morning, and I was asked to bring the car, that they have the part ready (Which i never was notified before), so I dropped my kids in school and took the car to the dealership, after waiting for more than 2hrs, they said they part wasn't good, and they couldn't get it fixed. I need help to get this fixed, and to have a warranty that this is safe and will work.
