2011 Mustang GT with manual transmission- inability to shift into 3rd gear. It almost caused an accident as I was stuck slowing down into on coming traffic. The car is been in the shop multiple times. Also has severe knocking in the engine that goes way after 5 minutes. Ford states this is piston rattle and they tried a software fix. Nothing helped.I'm afraid of the engine damage or catastrophic engine failure while driving. There are youtube videos posted labeled 2011 Mustang knock. Ford is aware... they referred me to it(at least the service tech did. Ford is doing nothing!!! the car has been in the shop 5-6 times and there is under 5000 miles. The car had only 300 miles on it when they had to replace the gas tank pump because it dropped to zero at with a half tank of gas left. There is a bulletin on this. Help before some gets hurt by the transmission problem or the engine blowing out!!!!

The contact owns a 2011 Ford Mustang GT. The contact stated that the check engine light was illuminated. The vehicle was taken to the dealer who diagnosed that the vehicle had a defective after market programmer and as a result, the engine exhibited an internal motor failure. The manufacturer was made aware of the failure but did not offer any assistance and voided the warranty. The VIN was not available and the vehicle was not repaired. The failure and current mileage was 7, 800.
