Front Suspension Stabilizer Bar problems of the 2015 Ford Explorer

I bought the car in September of 2015 and noticed upon hard acceleration such as entering the interstate or passing a car there is a smell of exhaust that comes into the cabin area and in order to relieve the smell the windows need to be cracked a little bit and this only happens upon hard acceleration. I have not had this experience with any other vehicle. I have also had problems with the transmission but they cannot seem to figure out when accelerating between 20 and 40 miles per hour you feel a shift in the transmission which for a new vehicle is a bit odd. At 10,000 miles I had to have a stabilizer bar in the front and replaced I notice a lot of heavy clunking as I drove my car around and this seems to be the problem. I I have also had issues with the headliner coming out on the driver side front door this is been pushed in and replaced 3 times and it's working on its fourth time. The issues with the transmission and the exhaust fumes in the cab and have yet to be resolved.
