2009 Ford Mustang acceleration problems

Filed Nov 13, 2023 · Acceleration, Engine · MI

The clutch/flywheel/ and or other components of the drive train/engine/transmission connection are faulty and are known to fail for the 2007-2009 Shelby Ford Mustang GT 500 as documented in the numerous Ford Technical Service Bullitens (TSB). This vehicle is available for inspection upon request. Late this summer (2023), I was driving this vehicle with my kids in the car and attempting to merge on the entry ramp for the expressway. I experienced a sudden loss of acceleration and the RPMs immediately "redlined". I had to pull over to the shoulder of the expressway so I would not be rear-ended. I researched this issue and found hundreds of posts on Mustang forums documenting this known issue and the TSB issued by Ford. I have reached out to Ford directly and had my vehicle inspected at a Ford Dealership. The Ford Dealership indicated the issues were consistent with the known defective parts. There were zero warnings either by warning lights or symptoms and I am just fortunate to have been in an accident with my children. I only have approximately 27,000 miles on this vehicle and it is not modified in any way. I have the dealership documentation as well that I can email at a later date. I unfortunately do not have it in electronic format at this time.

My son was driving his 2009 mustang and after stopping at a stop sign in a residential neighborhood, he slowly accelerated and the car suddenly accelerated quickly on its own. He said the gas pedal went to the floor, he tried pushing brake and it was not stopping the car. It sent him through another intersection, he engaged emergency brake to no avail. Luckily his car went through an area of soggy grass that helped slow the car down, and came to a stop by running into hedges and resting next to a brick church. He described hearing the RPM's revving up along with the sudden acceleration. He also described the steering wheel as "locking up".

I was traveling at about 40 MPH in mid morning traffic. I went through a traffic signal on a city street at which time my engine accelerated at a high RPM. I could not control the vehicle or stop it even though I had depressed the brake pedal. I did lose control of my vehicle, spun around totally my vehicle and another and then stopping against guide wire. The engine was still revving when the car stopped. No airbags deployed and I was transported by ems to the er.

My car stalled a few times when I stopped at stop signs then it didnt happen again for a few weeks. This time I was running into dunkins to get a coffee shut the car off came out 2 min later started the car went to drive away and the car would not accelerate. Shut off car waited a min restarted it and no problem drove on. A few days later same thing ran in store came out and it did it again. Brought it to a mechanic he hooked it up told me it was the electronic throttle control and it had to be replaced. He told me ford had recalls on many of the cars for this but no idea why the mustang was not recalled cause it used the same part as the other car. Had to get it replaced. They said if I kept driving it like that it would go into limp mode and thats very bad while driving on the highway cause that could cause a fatal accident. Not happy about this and don't understand why the mustang would not be on the recall list for this problem. The car tachometer was racing up and down periodiclly when I bought the car but the couldn't figure out the reason and said the car was fine. I'm not sure what kind of photo you want below. I have the original part the mechanic took out of my car and I have the invoice for getting it done. Is that what you need?

"takata recall" I was driving my 2009 ford mustang on a neighborhood street 30 MPH, when I turned a corner (10 MPH) I attempted to honk my horn and the passenger airbag deployed, my car accelerated with a hard right straight into a dumpster damaging the drivers side of the vehicle, the drivers side airbag did not deploy. I had purchased the car 6 months before this accident and the horn had not worked, we did not know there was a recall on the airbag at this time. This accident could have killed someone because the car became uncontrollable, the impact was so forceful it bent the frame of the car the damage to the vehicle is estimated at $7000.00.

I was driving along heading to the freeway and the car accelerator caused the car to speed up and I couldn't stop the car. I had to choose between going on the freeway or driving the car in a parking lot and into a pole to stop it.

I pulled into my driveway after returning from the store. As I began to slow down to pull in the garage the car accelerated causing me to crash into the front of my garage. The brakes were locked and the car did not stop but continued to push forward. I have skid marks the whole way up my drive into my garage from the car being pushed forward by the front tires..... I will be reporting this to ford motor company as their was a class action lawsuit for ford mustangs 2005-2010 if purchased in select states, mine being florida, which was part of this lawsuit. (was reported in usatoday for 3/23/13) I never received any information from ford regarding this. My car's front end and entire left driver side is destroyed as well as my garage. The accident caused my son's bike to come through my house.

My son was pulling the car into the garage which is a short distance from driveway into the garage. The car suddenly accelerated to a high speed. He stepped on the brake and pulled the emergency brake but the car would not slow down or stop. He rammed into a weight machine and cabinet in the garage which stopped the car. The car was put into park but the engine was still revving. There was front end damage across the entire front bumper and the air bag did not go off. This incident was reported to the ford motor co and I requested an inspector to come and examine the vehicle's gas pedal, brake override and air bags for defects but they have not been very cooperative. I do not want to have just the body work done and then be put back into the car and have the situation happen again.
