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. …
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.
