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.
Servo on transmission pushed snap out of retaining groove causing loss of transmission fluid while driving at speed. Servo pushed out of trans,car acted like it was in neutral than lurched ahead almost caused an accident.

I rented a car from thrifty in seattle, and was assigned an almost new Mustang. I found it extremely difficult to brake with my left foot without also hitting the accelerator. The pedals were very close and almost same height. I considered the car undriveable. I exchanged it ASAP, no surprise to thrifty.
