I got one for ya.
Backstory: Saturday we drove 400 miles north to Minnesota to purchase a 'new' 2016 Fiesta ST from Autonation Ford White Bear Lake. Mind you I work for Autonation Toyota in Libertyville. I get there, look at the car, looks great but gotta go (we drove straight up there to get the car and straight back home to Chicago so time was short) plus it was Saturday evening and we were one of the last deals of the day. The car had 806 miles when I purchased it, and it was titled new, not used, was told it was a dealer trade.
Problem: When I hopped on the highway away from Minneapolis, I hear this loud whiny supercharger like noise at around 70mph. It only comes alive under light load (cruise) or any load for that matter. Goes away when decelerating. Now that I'm focused on the noise you can hear it starting around 25mph, faintly. I didn't hear it right away because it was -7 outside and I got heat and radio on, no way I'm driving around in a frozen car to make sure noises were ok before I purchased it. I'm trying to figure what this is as I'm trying to get home, and once I started to hit the Wisconsin boarder from Minnesota I realized this was transmission related. It's too late to call the Autonation dealer, and I have to get back home because my gf has to work in the morning, so I figured it would be warrantable anyway. I took it to the Ford dealership next to my work first thing Monday morning. They tell me the teeth in the transmission are chipped, and it is not under warranty because they claim it is from abuse. I call the MN dealer and raise hell because the first 800 miles of the car was not a dealertrade, they had it the whole time, and tried to sell it 4 times. June was the last repair order they had for prepping the vehicle for a sale and it had 7 miles on it until the day I arrived last Saturday to purchase it (I can see this now because I'm at work and Autonation dealers can see everything in our region), there was a previous owner who turned it back in days later with 800 miles on it and they voided the deal, so it looked like no one bought it, so they can label it 'new'. Well, AN Ford tried to tell me to take it to the Lincoln dealer across the street and they would see what they could do, and re-diagnose it. They claim it is from the differential, and they cannot repair it because they don't know how to replace manual transmissions (wtf?). But they told me when the transmission becomes available, because they are on backorder apparently, they would sublet my car back across the street for that Ford dealership and force them to replace under warranty. The other day MN dealer calls me and tells me to bring it to a different Ford dealer that was 30 minutes away from me, because apparently they know some good people there that would do it and not be grumpy about it, apparently the Ford service manager next to my work told the AN Ford service manager to F off in different words. Anyway I take it to this other Ford dealership, and he was all bent out of shape, telling me how he has to fix other peoples problems, blah blah blah, during the test drive. Then he verifed something is wrong with the transmisssion and I told him yeah Lincoln said it was coming from the differential, and he was like 'this car doesn't have a differential', I'm like "... omg...", I just let him vent he didn't seem like he was having a good day anyway. He told me to bring the car back in 2 weeks and he will have his tech take the transmission apart, he said if it was a defect he would warranty it, if it is from abuse, I have to pay for it. I told him "AN Ford said you would take care of it", then he told me to just take it back then. So right now it sits at my house and I've been trying to contact a certain person, won't mention names, back at AN Ford and they are not responding back to me, but the Sales Manager did say if I don't want it they will take it back and void the title, probably like they did with the customer before me. Last I heard AN Ford was willing to order the transmission if it turns out to be customer pay and ship it to that other Ford dealer that is doing the teardown. I told them that I liked the car and I want to keep it but wanted this trans fixed without me footing the repair bill.
Mileage: 800, now 1300
Problem Fixed: No, unsure if warranty or customer pay at this point.
