    I have a 2015 Toyota Highlander XLE. Last winter I began noticing a burning smell which I believed to be electrical inside the vehicle. I was able to determine it was the driver seat heater and the burning smell continued even with the toggle switch turned off. I stopped at a local Toyota dealership, Koch Toyota, who refused to show me which plug under the seat to unplug to disconnect power. They tried to insist that I drop the car off and let them check it. Due to past…

    My Highlander had a strange burning smell and we couldn’t find where it was coming from. We took it to a shop where they checked everything over and suggested that the smell was our brakes. They lubricated the brakes and replaced my tires and struts. When I went to pick up the vehicle I still noticed the strange smell, and I had the mechanic come out and check. He suggested that it was the leather conditioner that our detailer had used. I left and headed for home and in…

We have pictures of the damage. 2) A second issue is totally separate from the first. This one has to do with the…
