2006 Ford Mustang GT Premium 2dr Coupe (4.6L 8cyl 5M)
Bought a new 06 GT leftover, after only one month and 1k miles the auto transmission started leaking, took it back for repair. A month later the car starts using lots of gas, running rough, no power, gas smell in car, and check engine light comes on. Take it back, dealer says 3 spark plugs are burned up, they give it back "fixed." Leaving the dealership same problems, take it back, they "reflash" the computer, say its fixed. Leave dealer, same problem, now the valves are clattering, take it back, they say "we'll have to talk to Ford and let you know." I call Ford, they say "we'll have to talk to the dealer and let you know." The dealer then says the valve racket is "normal" as is the gas smell.
Looks good sitting in the dealers service bay, appearance is all this car has going for it, the quality is horrible.
After 100 years Ford should know how to build a decent engine and driveline. Cutting corners on the important stuff has convinced me Ford and the Big 3 deserve to go broke.
