“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 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.”
