My Nissan Titan XD makes a sweet burning smell inside and around the vehicle when I drive long distances. So much so, I have had major headaches while I drive and now roll down the windows to get by. I live in WA and it is cold. This is a new vehicle and it started a year after I purchased. All Nissan did was replace the cabin filter and say it's fine. They don't understand it is poisoning me.

In the last year, my lungs have degraded and I cough constantly. I am wondering how many other people have had this problem and if I need to get a new truck before this one causes major health issues.
