3 Power Train problem

Failure Date: 12/16/2023

The following problem happened to me a few years ago (twice within a couple of months) and again, 2 days ago. Each time I was standing at a traffic light when all of a sudden it accelerated at full throttle. I practically stood on the brake pedal, but the car was inching forward, as I put the transmission into park. This was not a subtle situation, it was dangerous. The engine went from idle to screaming within 2 seconds. I ruled out the floor mat as it was in the proper position and snapped into the floor. It did not cause any warning lights to come on. In may, I had the oil changed, at which time they suggested that they clean the throttle body, which they did. They never heard of the above problem.

4 Power Train problem

Failure Date: 08/22/2023

Was driving my vehicle on the freeway traveling about 70 miles per hour when the vehicle suddenly shifted into first gear. I was able to maintain control and the vehicle shifted back to sixth gear. Issue occurred again within 5 minutes of the first incident and then the vehicle went into "limp mode". I was able to drive the vehicle home under this condition. Vehicle check engine light turned on and the code p0720, which is the output speed sensor circuit. This is the same issue that occurred on 2011-2013 f-150 and Mustang vehicles that currently have a recall for this (safety recall 19s07). The same transmissions (6r80) are used in both vehicles, as well as the powertrain control modules, but my vehicle's VIN did not fall under this recall. This is a very dangerous issue that could lead to a deadly accident.

5 Power Train problem

Failure Date: 06/20/2023

On 5-26-22 I took my Mustang to roush Ford in hillard OH. They tested and found out that I needed a lead frame connector. Part # al327627v $ 226. 10. I paid in advance for this part as roush said they would not order unless I paid in advance. Roush stated they would call when part comes in. I made several attemps to get status of part and all they would say is they were still awaiting. On or about 6-20-23 I called again, at this time they stated the dealership had been sold to valley Ford and still no word on part arrival. I have owned several Fords in my life but after awaiting over 1 yr on a part and car I could not safely have my wife drive I decided to trade it in for another vehicle. I then called valley to ask for them to credit my card in the amount of the part. They told me that the money went with roush and they could not return my money?? they suggested I call roush auto group( Honda ). I made the call to service manager and he said that roush Ford was no longer in business and they could not refund my monies. In my mind Ford was paid the $226. 10 and someone should be able to pay me back. I am asking that the Ford motor CO honor the deal by paying me back. Thanks.

Having rear end whinning noise, Ford worked on rear end components 6 times now. The last repair they did the replaced housing and carrier- pretty much brand new rear end. I'm still having rear end noise and they refuse me of any further repairs. Vehicle is in motion when I hear this noise only when accelerating, as soon as I take my foot off the gas it stops. I have a long history of this problem with them in Fords records.

17 Power Train problem

Failure Date: 02/19/2015

I am having problems with the transmission shifting from 1-2-3 when cold. The transmission does not want to go into 1st or 2nd without grinding and will grind an pop out of 3rd when trying to shift into it sometimes. I have been to the Ford dealer and was told that Ford knows about the grinding issue in the Mustang but will do nothing to fix it. I was told by the Ford service advisor that Ford was doing a fluid change to a heavier trans fluid and now they have stopped. Now I am left with a brand new Mustang that grinds the gears every day.
