Big Valley Ford Lincoln

Big Valley Ford sold me this brand new rusted/corroded Ford Expedition Platinum in late August 2016. At first, it all seemed very nice. After around three weeks, my nephew, who likes car a lot, was amazed at this brand new car, and looked all around and even the bottom of the vehicle, which found out that there are a lot of rust/corrosion on the suspension system. We went back to Big Valley Ford the following day (Sunday) and tried to find our sales guy Aaron and JZ, who didn't do anything and asked me to come back at a weekday. So the following week (Wednesday), I took a day off for that and found their Sales Manager Eric, who took my car to Big Valley Ford's body shop, and took pictures of the rust/corrosion. He said he'd seen this before and he assured me that the situation will be remedied and fixed. I waited for them to call, but no response for a couple of days, then I went to the dealership again and the sales manager Eric assured me again that the situation will be fixed and asked me to wait for his call. But I didn't get a call from him a couple of days later. So I called back and he told me that Ford said it's normal SURFACE rust (how surprising!) and they wouldn't fix it. It's a brand new car with that much rust/corrosion on the suspension and they claimed it's normal. I called them again to their service manager Jesse who wouldn't help either. Ford and it's dealership Big Valley Ford totally deceived their customers. They didn't tell me the rust situation when I bought the car. After the situation is discovered, they wouldn't fix it. I believe Ford had totally tarnished its brand. I don't think anyone seeing this would like to buy a Ford again.
