There is a constant source of water that lines my passanger side carpet floor, anything that is on the floor soaks the water up and gets wet and the carpet is always damp with liquid, I'm told it's something with the air conditioning but it happens when I use the heat as well.
Either in 2008 or 2009, shortly after purchasing a brand new 2007 Ford Fusion, I was greeted with the first major issue of my brakes going out on me while driving. Find out this was due to a defective master cylinder. The engine light turned on within 3-4 years of having the vehicle, and was found to be related to the thermostat, the engine would always run towards the cool end, never going above 1/3 of the way to the halfway mark. That was fixed after years of failed attempt. And all the while, I never had a functioning air condition unit and would have to repair yearly, and then found to be related the car always running too cool. Over the past two years, I have had to replace the gasket twice, because oil would appear in places it should not (I always maintain my car by doing the oil changes, etc on time). This past Sunday, I was driving and going around 70 mph when my car started to decelerate to 65, then 60, then would not go past 40 so I pulled off the interstate and drove back home. Over the next couple of days I smelled burnt oil, and the same issue with oil being where it should be happened again. Mechanic is telling me it is done, and after researching, this is not something unique to just my car. This is dangerous and people have reported many horrifying stores on the same issue, with some people's Fusions combusting and stalling them on the highway. I did notify the Ford company today of all the safety issues and other issues related to my car, just so they have it documented on their end as well. I am appalled this car does not have recalls other than the one related to the airbags, which they can not fix yet, posing my passenger at risk.
