2014 Honda Pilot wheels problems

Issues: 1 - steering constantly vibrates at speeds above 45MPH. Smooth roads higher vibrations. This vibration increases to extent that you feel that you are loosing control of the car at speed above 70MPH and you can see the steering vibrating. So effectively, you cant drive you car beyond 70MPH. 2 - transmission shutters at cruising speed above 35MPH and searches for gears while going down hill. 3 - sudden burning smells in the cabin to an extent of air becoming toxic inside cabin.

I have been noticing that when I brake my vehicle shakes - took it in to have the brakes done and the dealership told me that my brakes looked brand new and wanted to send me on my way. I asked well why is it shaking then and I was told that maybe the roaters needed machining a $207 service. This was after they did not bother to call me to tell me my vehicle was ready I just happened to show up an hour after my scheduled appt time so machining my roaters would have been another hour to 2 hour wait.
