I am the owner of a 2012 Ford Mustang GT currently located in Kuwait. My vehicle has an open Takata airbag safety recall, which is a life-threatening defect. I contacted the authorized Ford dealer in Kuwait and Ford Middle East, but both refused to perform the recall repair, stating that the vehicle is a "gray market import" and not eligible. They also attempted to condition the repair on paid service, which is unrelated to safety recalls. Additionally, the authorized dealer informed me that my vehicle has a total of four open recalls, not just the Takata airbag recall. Despite this, they still refused to perform any of the recall repairs due to the vehicle being a "gray market import." This refusal leaves me driving an unsafe vehicle with no official repair solution. …
I bought the car on Dec 20th 2024. The dealership informed me of the recall and turned off the passenger side airbag. I returned to the dealership as scheduled about 2 weeks later. When I went to pick up my car after work the service center said they couldn't fix the problem because the airbag didn't exist and sent me on my way. I tried calling the sales person but had to leave a message. There has been no other communication.

Recently started having erratic shifting issues. Will downshift randomly out of nowhere while driving. Sometimes will just be stuck in 1st gear and won't go anywhere until I pull over and shut off/start up again. Dangerous because I never know when it will do it. Might seem like everything is fine and then all of a sudden, it downshifts and loses power. Rpm's rise but car has no power. Have to figure out how to get out of the way. As stated in ford's " Customer Satisfaction Program 16N02," my 2012 has all the symptoms and I have DTC code P0731 but dealer refused to service my vehicle because it doesn't show up with my VIN, even though it's a 2012 and I clearly need my Molded Leadframe replaced.
Speedometer went to zero while driving and seemed to be in neutral. Could not accelerate. Also low fuel warning light came on when I had a full tank. After car was shut off and restarted speedometer seemed fine for about 1 mile, then self accelerated. Now continues to read zero and can not accelerate unless I restart engine.
