Was in the car during a very slow, around 5mph front end collision. The knee airbag went off at low speed. I. Exited the vehicle to look at damage and then I sat back in the driver seat. Upon sitting back in the driver seat I noticed the smoke that had cleared from the airbag had started to build back up and became more dense. I had my feet outside the door while sitting in the driver seat and when I when I looked around I noticed a fire getting larger and larger from the pillar to my left, between the rear seat and the front driver seat. I didn't have anything to put it out so I tried to blow it out and it was getting larger and larger melting more of the plastic up the pillar. I ripped off a work shirt I had and was able to smother the fire with it. Had I not been able to smother it this fire would have engulfed the whole vehicle. …

The 2015-17 all have the same issue with the ac system as a whole, it is very faulty and not safe. This is due to a manufacturing defect. The ac constantly blows hot air even when on cold and only on to the windshield which causes visibility issues which could be fatal for me or anyone on the road. I went to ford yesterday to ask about the issue which I was told "we only have one person today that can look at it" and was later told that he wouldn't take a look, without any reasoning. I had to go to a different company to get my car diagnosed. As I stated before this is a occurring issue with the year make and model of my vehicle.

Was driving, all the sudden I heard a pop and a little bit of smoke and the smell of burning plastic came from under passenger seat. Pulled over, noticed it was coming from electrical harness under seat that controls the heated and cooled seats. Disconnected plug and saw that it had burnt out & caught fire. Have left it unplugged with no incident since.
Was driving and the traction control light came on car started shaking, pulled over got out to look and the car was on fire. Fire started in the right rear of the trunk Where the backup camera wire harness is located. It has not been inspected. Car is currently at an impound lot but is available for inspection.
This 2017 Ford Mustang was taken into Gillespie Ford for the RECALL on the rear back up camera. This was done on May 31, 2023. The dealer said they fixed the camera. I have only taken this vehicle out twice since they "fixed" it. Yesterday was extremely hot. When I used the backup camera in my garage after I got home, the camera image was distorted just as it was before the RECALL REPAIR. This problem with the camera has not been fixed properly and the dealer wants to charge me for any further repairs, even though it has not been fixed properly or FORD still has a severe issue with these cameras when they get hot. I would like someone to step up and make the dealer fix this as it was a RECALL. I believe I should NOT have to pay for another repair. They have not done this properly.
I had a recall repaired on my 2017 Ford Mustang at a Ford dealership, the recall repair had to do with the backup/rearview camera not working properly. After they repaired the wiring in the trunk compartment, the back up camera is still not working properly and becomes blank or distorted when putting the vehicle in reverse. I called the dealership to have it looked at and fixed because the nhtsa website states that "Dealers will inspect and repair the decklid wiring harness AND/OR REPLACE THE REARVIEW CAMERA, as necessary, FREE OF CHARGE.". The dealership inspected my 2017 Mustang, again, and sent me a text message with a website link attached stating the cost for the repair and that I would need to pay for the repair totaling $316.59.
