I bought a 2017 Mustang GT Premium from them in December and in February and, after 1000 miles I took it to my mechanic and he I were shocked to see corrosion/rust in a lot areas of the undercarriage and suspension components. There are some areas that are normal to see surface rust but this was far beyond that. It was on brake line brackets, painted surfaces of suspension components, etc. This car literally looks like it sat in water. This was obviously sold to me like this, as there is no way this could have happened to a Florida car in that period of time to a car that is garage kept and driven locally. After many emails and phone calls I took it in and looked at it with the service manager and he confirmed that it was excessive, and we compared to another 2017 next to it and it was obviously excessive.
He had previously told that per his warranty guideline this was not covered, and provided his guidelines. What he showed me did not match the warranty I received with the car, or what is available on Ford's website.
He said my best bet was to report it to the BBB Autoline as that would force Ford to take a look at it. According to him if either he or I called Ford about it they were unlikely to respond favorably.
I called Ford and they also referred me to the BBB Autoline, so he was correct on that.
I was then asked if I would be willing to trade it for another one, which I took as a even trade/swap. Boy was I surprised, although I don't know why.
To add insult to injury they tried to offer me trade in price for my car to go towards another one, which would have been almost a $5000 loss for me (not counting taxes, etc.). What a waste of time and disappointment. So much for doing the right thing. I guess it's on to the next step in the process....
To be clear I hold Mullinax Ford responsible, although they do not feel the same way. I feel it was like that when I bought it and they should have known better.
Buyer Beware, and make sure to check the undercarriage of your car.
The sad thing is I had recommended them to some friends, and had to take it back based on my experiences. I would give them a zero rating but I am not sure that is possible.
If you go to "mustang6g" forum and search for undercarriage corrosion you will see pictures.
Judge for yourself. Would you find this acceptable on your new car? Mullinax and Ford do.
