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 about 5 miles the control for the drivers heated seat started smoking and about 30 seconds later the plastic around the control began to melt and flames were coming out of the area next to the control. I was able to use a fire extinguisher to put the fire out. All of the heated seat components were original and we haven't had any work done to it. …

The rear tail gate seal for lamps on both the left and right side have failed and the lamp assemblies condense and fill with water. I have read other reports on your website of the same problem with the highlander. In your other reports the a person was told Toyota will not warranty the lamps because of moisture in them because it is not a safety issue. While it is because the moisture blocks the light for the vehicle behind to see and thus rear end. I live in Massachusetts and there is a yearly vehicle inspection and when I went to get it done I was told it would not pass safety inspection with moisture in the lamp so I had to get the left hand one replaced to pass. Now 6 months later my righthand tailgate lamp is full of moisture and will not pass my upcoming Massachusetts safety inspection. The cost was $205.44 now another of the same. …
