I had bought a 2013 MKX from Planet Lincoln. The vehicle had a lot of interior noise from the road and surroundings. I was told by the service manager that this was normal. I went back to the sales associate and explained that I was not satisfied with the noise the response I got was too bad there is nothing we can do for you. Very pricey for a sub par vehicle
Sorry to hear about your MKX and the troubles you seem to be having.
If you are somewhat in the area of North Florida, feel free to swing by North Florida Lincoln and allow us to service your MKX, as our service department is without peer, and our personal service is above reproach.
Just ask for Keith, and I will ensure that everything possible will be done, in order to ensure your satisfaction.
