NHTSA Complaint #11463463 — 2014 FIAT 500L

So the dealer fixed the transmission / power train recall in 2020, my car is now doing exactly what the recall states, getting stuck in park, asking me to put engine in neutral and then drive without the car moving, so on and so forth. Fiat, as well as the repair dealer northside imports, is refusing to fix this issue as they state the car is out of warranty, and they feel they fixed the recall. This car only has 73k miles on it. The other issue of complaint is that the wire melted on the blower fan for the ac unit. Smelled burning wires in the car, and both fiat and dealer state that is normal wear and tear. That is not, as it could have caused a fire inside the car, luckily i was able to pull over and put out the smoldering wire. I need this fixed, and fiat is refusing to cover. They stated i need a new power train module and transmission which cost 12k which is 4k higher than the actual value of the car. During this whole time, fiat and the dealership was recommending that i purchase a new car. I want to know how i can get this fixed or the manufacturer to acknowledge they have a safety issue. I also got charged 326 dollars just for them to diagnose the issue. nothing fixed. 326 dollars to plug in a machine for 15 minutes. This is very wrong.
